Notre-Dame de Paris: What to Do with This?

Coincidences and connections: life presents us with some interesting situations. “Pre-ordained” is not the proper phrase for what sometimes occurs, and yet the situation is often rather inexplicable – puzzling, to say the least.

My wife and I were at the gym, yesterday morning, for our usual Monday workout. Linda was already upstairs on the treadmill, and I came up to join her. As in most workout facilities, there is a bank of televisions overhead for the patrons.

As I stepped up on the machine next to hers, she said to me, “Notre-Dame is on fire!” There, directly overhead, was an image that was no less unbelievable than was the sight of New York’s twin-towers smoldering some eighteen years ago.

As the day played itself out, we, collectively, slowly but surely, lost one of civilization’s most precious icons. Notre-Dame de Paris has exemplified, for over nine-hundred years and many generations, what humans can accomplish by setting their sights beyond existing horizons…and working together on a common cause.

These past few weeks, my wife and I have been busily reorganizing our household with an eye to streamlining and simplifying our future lives. This has entailed going through the myriad of memories preserved over our lifetimes, memories residing on bookshelves and within file cabinets. Accordingly, the house is currently a mess, with papers, files, and “stuff” scattered all over.

Why This One?

Slowly, but surely, we have discarded “stuff” and consolidated storage for all the rest. There was one item whose future fate I had not yet been able to determine: “Shall I keep this or not, and if I do keep it, where will I put it?”

“It” is a travel guidebook from 1975 with illustrations and information on Notre-Dame de Paris. Two days ago, with a sense of frustration and after hours of difficult mental verdicts on so much “stuff,” I laid the book on our living room end-table: “Fate to be determined, later,” I thought to myself. And then yesterday happened. Yesterday, I took these pictures, as well.

We had been to Paris as a family in 1994, and we acquired this little book at the very same time indelible and precious memories of Notre-Dame de Paris were being formed. I will find a good, safe place for this little book as we all grieve for our loss in far-away Paris, the City of Light.

The Navy’s Blue Angels Begin Another Season

This past weekend brought the 2019 version of the Navy’s renowned flight demonstration team, the Blue Angels, to Salinas, California. Salinas marked the second of many stops on the Blues’ performance calendar for this year.

For the uninitiated, I offer the following:

-The mission of the Blue Angels is to demonstrate the performance capabilities of the modern Navy’s latest aircraft and the Naval/Marine aviators who fly them. The carefully chosen team of six aviators is comprised of the best of the best in Naval and Marine aviation. They execute the team mission by flying difficult maneuvers at high speed while maintaining very close proximity to one another in formation. This is not stunt flying. The difficult and precise routines are performed to demonstrate the ultimate capabilities of both men and machines.

-If you have never seen the Blue Angels, by all means, go do it! I can confidently speak not only for myself, but for millions of others who have attended their airshows when I say that the excitement of seeing a Blue Angels performance will rank near the top of anything the average person will experience in a lifetime. I still recall the memories of my earliest exposure, nearby at the-then Moffett Field Naval Air Station; that was in the mid-nineteen-fifties. Since then, I have seen the Blues perform several times: the thrill is ever present with each performance!

The Blue Angels were formed in 1946, just after the war. During that first year, they flew the venerable Navy warbird, the Grumman F6F Hellcat. The following year, the team embraced the faster Grumman F8F Bearcat. The team entered the jet age in 1950 with the Grumman F9F Panther. The Blues’ current ride is the McDonnell Douglas F/C-18 Hornet, an iconic airplane which has earned the longest tenure with the Blues of any airplane (the F/A-18 in1986).

This airplane is currently transitioning into an advanced configuration called the “Super Hornet.” The Navy has chosen to forego the latest high-performance airplane available in the arsenal, the advanced F-35. Procurement, maintenance and operating costs for the F-35 relative to the Hornet dictate that decision.

While anyone witnessing a Blue’s performance cannot help but admire the capabilities of the men who fly these yellow-trimmed, azure blue Hornets, my mind also focuses heavily on the aerodynamic beauty and raw power of the F-18 itself. The brute power of the airplane manifests itself with a deafening roar as the Blues roll down the runway using full afterburners during take-off. For much of the performance, the sleek Hornets slice through the air almost silently at first, only to be followed a split second later by the throaty roar from their powerful jet engines – even with afterburners off.

During their performance demonstration, the Blues’ two solo airplanes, tail-numbers five and six, employ full afterburners as they skim low across the field and rapidly swing nose up into a vertical position prior to heading several thousand feet straight up into the deep blue sky – all with no loss of momentum. To witness such performance from a flying machine is to marvel at the vision, determination, and engineering brilliance of its creators. Equally incredible is the realization that what is on display right before one’s eyes is occurring a mere one hundred and sixteen years after the Wright Brothers first left the ground for twelve seconds in 1903. That fragile machine was powered by a tiny 12 horsepower, four-cylinder piston engine machined by the Brothers’ bicycle shop mechanic, Charlie Taylor.

I like to call such positive experiences like the Blue Angels “perspective builders,” experiences which go a long way toward neutralizing the demonstrated array of follies and foolishness that history attributes to the human-race – individually and collectively. There is a sad irony, however, in the realization that some of the greatest and most rapid advances in aviation have been motivated typically by the prospect of fighting wars!

At the Airshow, It’s Time to Fly: The Excitement Builds!

In the opening moments of the program, the pilots stride six abreast with military precision along the flight line as they approach their airplanes which are precisely parked in numerical order along the line. The eyes of the crowd are affixed on the pilots, naturally, but I tend also to notice the crew chief assigned to each pilot/airplane standing by his/her aircraft, hands behind the back, waiting to swing into action. Like their crew chief counterparts in World War II combat aviation, they, too, are unsung heroes tasked with the responsibility of keeping their airplane in flying condition. In the same vein, I also appreciate the skilled mechanics who travel with and are part of the Blue Angels organization, responsible for the perfect condition of all six airplanes. There is no room, here, for less than “perfect.”

The group commander flying Blue Angel number one moves first to his airplane from his position in the procession down the flight line, followed sequentially by the pilot of number two, and so on. Each pilot “mounts” his aircraft and deftly clambers into the cockpit of an airplane which is meticulously groomed ahead of time by the support staff under the watchful eyes of each crew chief. The crew chief helps each pilot “strap” into his airplane. Then, matching yellow helmets are donned by each pilot and electrical connections made to the vital on-board communications equipment which connects all six airplanes with each other… and the ground. Now the crew chiefs step nimbly down off their airplanes and, starting with Angel number one, the Hornets’ canopies close in sequence down the line.

The excited tension in the crowd is now palpable as a perceptible “whine” and loud “whoosh” emanates from the engines of Blue Angel number one, usually accompanied by a thin puff of white smoke expelled from the tailpipe. The same scenario repeats with Blue Angel number two and so-on down the line until a very robust whining/shhhhh sound emanates from the entire flight line. Now number one pulls out from the flight line turns and starts for the taxiway, followed, as always, in sequence by the rest of the team. In a few minutes, the crowd will hear all engines release the throaty roar which signifies the take-off roll with afterburners and the start of yet another in the long line of incomparable Blue Angels flight demonstration performances.

The airshow crowd is peppered with young children whose parents brought them to see the modern-day version of the barnstorming phenomenon of the nineteen-thirties: a pilot and his Jenny bi-plane landing in a farmer’s field to demonstrate to the amazement of local folks what he and his airplane can do.

My wife and I took our two young grandsons to the airfield last Saturday to see the Blues. I wanted them to experience the same inspiration and unforgettable panorama that I was fortunate enough to witness as a teen-ager – the impressive display of men and machines at their very best. The boys loved it! They all do.

 

 

 

 

 

 

 

 

 

 

 

“While England Slept”: Winston Churchill and Serendipity at the Book Fair

Last weekend, Linda and I went to a book fair in South San Francisco: I had a very interesting experience as a result. We had a choice between attending this smaller, “book and paper” fair or the annual International Antiquarian Bookfair across the bay in Oakland, one of the largest of its kind in the world. We have been to many of those over the years, and they provide a dazzling experience for any bibliophile. But we opted for the simpler afternoon excursion closer to home where book prices are not so astronomical. Linda bought a few inexpensive items, but I came home with an empty shopping bag. There was one book which did capture my attention – a very nice but pricey copy of the 1940 publication by a recent Harvard graduate, one John F. Kennedy. Its title: Why England Slept. That title rang a bell in my mind: I believed it to be an important book explaining how England was so unprepared to deal with Adolph Hitler’s subjugation of Europe in the late nineteen-thirties. Because I have a very strong interest in the subject matter, the book was tempting but for the price and a considerable degree of uncertainty on my part. I decided to pass and do some research on both the subject and the book.

Caution can be a very rewarding virtue, and so it was in this case. Back home, I quickly discovered that young Kennedy’s book sprung from his senior year college thesis and was ostensibly a coat-tail project which followed Winston Churchill’s 1938 publication titled, While England Slept. This latter book contains a collection of Churchill’s opinions and speeches in the period from 1932 to 1938 whose intent was to warn a “sleeping” England and Europe of the dangers posed by Hitler’s rapidly spreading dark shadow. Young Kennedy’s book focuses on the reasons why England was so unprepared prior to Dunkirk and the ensuing Battle of Britain. At least one reviewer panned the book as the relatively immature effort which might be expected of a recent college graduate, no matter how bright! Whatever merits Kennedy’s effort might possess, it also seems clear that old Joe Kennedy had a hand in his son’s publication and its success in the marketplace by calling-in a few personal favors within the publishing world.

It was immediately clear to me that Churchill’s book was THE book to have and read, and it was this title of which I was vaguely aware. Of course, only Winston Churchill could be the author of such an important book, a book that gives throat to a lone voice warning of impending disaster for Britain, indeed for all of western civilization. I am relatively new to the detailed panorama that was the thirties, with its dark Nazi storm clouds forming, and the forties when lightning struck the world at large. But I do know this much: Winston Churchill was likely the greatest figure of the twentieth century. This uniquely colorful character of a man seemed, by some pre-ordained, divine destiny, to be uniquely qualified to do what he did – which was no less than saving the world from Nazi tyranny. Indeed, Churchill himself deeply believed that such a destiny was his protection from risk and harm when he often emerged from underground air-raid shelters to quickly survey the damage from Hitler’s latest blitz attack on London. These images of him amid the smoking rubble and his desire to be among his people were not lost on Londoners.

England survived two major crises subsequent to the infamous appeasements of an invading Hitler by then Prime Minister Neville Chamberlain in the vain hope that an independent England and a Nazi dominated Europe could peacefully coexist – never a possibility in Churchill’s mind. The first crisis was the potential immediate loss of most of Britain’s 250,000-plus army at Dunkirk after Nazi tank divisions and the Luftwaffe had forced the weary remnant of British troops to the sea near that small French village. Only a miraculous small-boat “armada of the people” saved the army by ferrying it across the English Channel to Dover, literally overnight, while the Nazi’s bided their time, assured of victory, so they thought.

The second historic event that saved the nation, known as the Battle of Britain, was fought in the skies above the English countryside. From July to October of 1940, a planned German invasion across the English Channel from occupied France was stymied by the intrepid young fighter pilots of the Royal Air Force. These youngsters, most barely 20 years of age, were badly outmanned in number and equipment, yet they answered the call to scramble their Hurricanes and Spitfires three, four, and sometimes five times a day, intercepting German bombers and fighter escorts of the Luftwaffe whose directive was to destroy RAF airfields and aircraft in preparation for Hitler’s imminent invasion of the island nation. The invasion never happened. The Luftwaffe’s losses signaled the beginning of its end.

After three months of deadly combat in the skies and destruction rained down on British soil, Hermann Goering’s superbly equipped Luftwaffe was beaten back by the courage and skill of the young pilots of the Royal Air Force. Today, there are barely any of them left, those young Brits who flew Hurricanes and Spitfires against the Luftwaffe. Thankfully, there exist a number of excellent interviews and film documentaries which feature the dozen or so survivors still alive several years ago. Go find them and watch them and find out for yourself why Churchill eulogized them forever with his famous words, “Never in the field of human conflict was so much owed by so many to so few.”

“Alone.” That word for many months symbolized the state of both Winston Churchill and the British island nation after Hitler crashed his way across Europe, finally occupying neighboring France on June 17, 1940. Weeks earlier, on May 10, Winston Churchill replaced Neville Chamberlin as Prime Minister. England finally had heeded Churchill’s urgent warnings about Hitler and the need to rearm, but almost too late. Churchill had thought it might be too late, once France had fallen.

So, it is this 1938 book of Churchill’s, While England Slept, which I purchased from a bookseller last week, that embodies those urgent warnings of Churchill to pay heed to the Nazi threat while putting aside the memory of Britain’s revulsion to the all too recent World War I experience. Late last year, the fine movie, Darkest Hour, had implanted in my head the full measure of Churchill’s greatness. His written and spoken eloquence remind me of another great leader/statesman with similar attributes, Abraham Lincoln. It is said of Lincoln, that he saved the union. It can truly be said of Churchill that he saved Europe and western civilization. Lincoln also found himself very “alone” during his first months in the White House as the Civil War raged around him. Although from opposite ends of the personality spectrum, similarities between the two men and their history abound – including well-honed personal senses of irony and humor.

I had already been into Churchill and World War II history for some years before serendipity brought me to this latest book acquisition last week. I now have all the material resources required to truly learn the subjects in greater depth. Along with the problem of available bookshelf space, only available time can slow me down!

 

World War II Aviation at the Lyon Air Museum

While visiting our daughter and two granddaughters at Christmas, I received a very nice Christmas present from them: an afternoon at the Lyon Air Museum, in Southern California! The Lyon Air Museum is located at Irvine’s John Wayne Airport and contains many vintage World War II airplanes, all beautifully restored, most in flying condition. In addition to the airplanes, many other vintage conveyances from the era are displayed, including one of Adolph Hitler’s personal staff cars, presumably used by him to ride into Paris after conquering the French in 1939.

One of the museum’s prized flying airplanes is the B-17 heavy bomber, Fuddy Duddy. The tradition of painted “nose art” on World War II aircraft was prevalent particularly on heavy bombers such as the B-17 “Flying Fortress” and the B-24 “Liberator.” These four-engine, long-range bombers were as instrumental to the defeat of Germany as any weapons in the U.S. arsenal. The B-17 earned its renown by destroying much of Germany’s military and civilian infrastructure, flying out of large air fields located in the English countryside.

I relished the afternoon we spent in the museum with our girls, not only because I have long appreciated the history of World War II aviation, but also because I had a rare chance to give my grand-daughters an up-close-and-personal awareness of another time, the “greatest generation,” and aviation’s important role in defining the path of world history. There is no substitute for experiencing, up-close, the mystique of these great airplanes in order to appreciate their role in that history.

Peering up into the underbelly of Fuddy Duddy through the crew entry hatch is bound to stimulate any teen-ager’s appreciation of the courage it took for crew-members to clamber up inside such a large, complex airplane for dangerous mission after mission over enemy territory. So many crews and men never made it to the magic mark of twenty-five completed missions which would give them a one-way ticket back home, perhaps to become a flying instructor training pilot-recruits. Many thousands of B-17 and B-24 crew members went down in the gunsights of swift and deadly German fighter planes whose mission was to intercept and destroy the “heavies.” And there were the thousands of huge, long barreled German flak guns on the ground, poised and ready to fill the high skies with exploding shell fragments, any one of which could rip apart men and machines alike.

It was gratifying to observe the curiosity and interest which quickly developed as we began our tour of the museum! Soon after we started at the B-17, we spent a half-hour in the museum’s mini-movie theatre to watch a film documentary on the air war over Europe which included much aerial footage and commentary from Andy Rooney. Rooney was the long-time, now deceased, CBS commentator on 60 Minutes. During the war, he served as a war correspondent experiencing, first hand, the B-17 during actual missions. I was pleased to note that the film was one included in my personal DVD collection of worthy war documentaries; one cannot help but be impressed by the viewing experience!

A museum docent approached us as we examined the B-17 and produced two dummy bullets to illustrate the fire-power of the thirteen .50 caliber machine guns positioned at six locations around the airplane. Alongside the .50 caliber sample, the .22 bullet looks downright puny, and, yet, these airplanes were still very vulnerable to German fighter interceptors until late 1943 when the fabled P-51 Mustang fighter was introduced which could escort the bombers deep into German territory and back. The .50 caliber machine guns on the B-17 fired thirteen rounds per second, all fed from long cartridge belts. After a protracted aerial battle with German interceptors, the waist gunners stationed inside the fuselage at both sides of the airplane were typically ankle-deep in empty brass shells ejected from hot, rapidly firing guns!

One of Hitler’s several Mercedes Benz personal staff cars –likely the one in which he entered Paris after the Nazi victory in France.

A sign on the wall provided a summary of the debt owed to the men of the Mighty Eighth Air Force which operated B-17’s out of England. Among its stats:

“Hitler started boasting that he converted Europe into an impregnable fortress. But he neglected to provide that fortress with a roof.” Franklin D. Roosevelt, message to Congress, September 17, 1943.

-2,300,000 sorties flown
-24,228 enemy aircraft downed
-350,000 served in the Eighth Air Force.
-47,742 killed in action.
-696,351 tons of bombs dropped.

Of course, these numbers pertain only to the Eighth Air Force, not including the other arms of the Army Air Force and their theatres of operation.

All in all, we had a very fine afternoon at Irvine’s Lyon Air Museum. I heartily recommend it for adults and youngsters, alike! Our thanks to the spirit and generosity of Gen. William Lyon for preserving this important collection and for making it available to the general public.

Time to say goodbye: our Southwest Airlines 737 pulls into the gate at John Wayne Airport for the trip home.

My Childhood Wood Pond Boat: Retired in Dry-dock After 72 Years!

For as long as I can remember, this proud little pond sailboat has been a part of my life. My parents bought it for me in Chicago, Illinois, before we moved to California in 1948. I would guess I must have been five or six when I received it.
After decades of lying around in some obscure corner of my den and early boyhood bedrooms gathering dust, my little boat now rests in a “display dry-dock” which I installed above my garage workbench. Now it is out of the way, protected, and easier to see and enjoy!
My earliest recollection of this little wood boat lingers, still, in my mind’s eye: My parents and I were at a public park in Chicago which contained a large, shallow lake/pond with a fountain in the middle. My sturdy little boat was well underway on its first trip across the pond that day, sails full of a fairly brisk breeze which blew across the water. Suddenly, my excitement turned to dismay as my little craft leaned heavily to the side and capsized. With her sails now wet, she had no chance of righting herself and drifted aimlessly on her side, quite some distance from where we launched her on the pond’s edge.

The situation called for a daring rescue plan! I removed my shoes and socks, stripped down to my underwear and waded into the knee-deep pond – all modesty abandoned and intent on rescuing my little craft – which I did. That episode ended my boat’s sailing adventures for a long time; clearly, she would again meet the same fate if the breeze were sufficient to capsize her.

In 1948, my father was transferred by United Air Lines to San Francisco, California, and we settled near San Francisco Airport in nearby Millbrae. Soon afterward, my father – who possessed a superb mechanical engineering mentality in addition to being, by far, the finest craftsman I have ever encountered – must have begun thinking about my little boat and its obvious sailing limitations.

The July, 1950 issue of Popular Science magazine contained my father’s article titled, Make That Toy Really Sail, which documented nifty modifications which he made to my boat to deliver the sailing performance promised in the article’s title. In the magazine layout for his brief article, my father used my younger sister Karen’s boat (originally identical to mine) to illustrate the modifications required. Although hers was purchased a few years later than mine, it was from the same manufacturer. The accompanying picture shows Karen at Stow Lake in San Francisco’s Golden Gate Park launching her modified craft for a brisk, straight sail to the other side of the pond. She and I would launch our boats and run around the short-side lake perimeter to be there in time to greet our arriving sailboats.

After Dad’s ingenious fixes, our boats no longer could capsize because of the lead fishing weight hammered onto the keel. The end of the rear sail boom was now attached with string to the limited-range rudder tiller which counteracted the tendency for the boat to align with the wind and stall-out. In simplified terms: The rudder now could assume one of two “fixed” positions, determined by which side of the sail was receiving wind. The wind force on the main sail and its rigging acting alone generated a torque which tended to turn the boat, aligning it with the plane of the wind at which point the sail would ineffectively flap back and forth, stalling the boat. The action and slight angle of the rudder steered the boat in the counter-acting direction to the torque from the sail. Now, our little boats steered quite steadily across the pond in the direction of launch with no danger of capsizing…a great improvement!

I presented my sister with the original article and magazine cover which we found in my father’s papers after he died in 1992. Typical of his other early contributions to Popular Science, he likely received around $40 for his article – a fair sum in 1950 and a welcome assist to our young family’s strained budget in those days!
I feel a real kinship with this little boat of mine: We have been together, now, for almost seventy years; although a little worse-for-wear, my sturdy ship is still intact although not as seaworthy as she once was. I cannot help but appreciate how aptly these circumstances apply to her owner, as well! I also love my little boat as a constant reminder of the close family ties my sister and I have long enjoyed. And finally, my little boat reflects the industry, ingenuity, and craftsmanship that were among the hallmarks of my father, Alfred C. Kubitz – a most uncommon man.

Thomas Edison’s Biggest Mistake and Nikola Tesla’s Greatest Triumph: AC vs. DC Power for America’s Power Grid

Thomas Edison, America’s homegrown inventive genius, and Nicola Tesla, an immigrant from Serbia who arrived with four cents in his pocket at Castle Garden, New York, in 1884, were as different as day and night. Both men are remembered, today, as inventors with “genius” insights, and they each set out to tackle one of history’s great engineering challenges and commercial opportunities at the close of the nineteenth century. Their technological approaches to the challenge were diametrically opposed: one of these men was destined to win and the other to lose and lose big.

Thomas Edison, whose triumphantly successful electric lightbulb began to light the nation’s darkness in 1879, was to fail miserably in his efforts to provide the nation with sufficient electrical power to light the millions of his bulbs which rapidly materialized in homes and businesses across America.
Edison’s encore to his triumph with the light bulb was nothing short of designing and installing a series of prototype electric power stations which, if successful, would serve as a prototype for America’s first true power “grid.” Whoever first established a foothold in electric power would reap immense financial rewards.

On our recent vacation trip to Michigan, we spent a full day at Henry Ford’s Greenfield Village (see my previous blog post) and toured the recreation of an early Edison electric power station. Inside the brick building, a remarkable collection of Edison artifacts included one of the original steam-powered dynamos (electrical generators) used by Edison in one of America’s earliest power stations. That “Pearl Street station,” located in the heart of New York, was used from 1882 to 1890 to illuminate and power several square blocks of buildings which had installed Mr. Edison’s recently perfected lightbulbs. A fire destroyed the station in 1890 along with five of the six identical generators installed therein. The sixth and surviving unit was the very one on display at Greenfield Village.

This machine delivered low-voltage, direct current (referred to as “DC”) to its electrical load within the Pearl Street neighborhood – presumably a large array of electric light bulbs as well as small electric motors and electric appliances. A dynamo, when appropriately configured, can also generate alternating voltage, thus delivering alternating current (referred to as “AC”) to an electrical load. The reality is that a DC dynamo is slightly more complex electro-mechanically than is an AC dynamo. A DC machine is an AC machine with an electrical polarity-switching device called a commutator installed on the rotor.

Why Did Edison Choose a DC Based System? GOOD QUESTION!

First, a little elementary background: no formal math/science required!

The simplest version of rotating dynamo inherently generates alternating voltages in its individual rotating coils. The term “alternating” implies that the voltage generated is not constant in value and polarity over time: instead, the amplitude of the voltage varies while the voltage polarity reverses between “positive” and “negative” and back again some sixty times each second (in the North American, 60 cycle, AC system). This polarity reversal can be visualized as alternately a push then a pull on electrons whose resulting mobility/response constitutes electrical current in the connecting wire.

A garden hose analogy will help to visualize AC/DC current behavior!

Think of a DC electrical circuit as a garden hose (the wire) through which water (electrical current) flows at a constant rate in one direction into a basin/receptacle (the electrical load) in response to a steady water pressure (voltage) at the supply side of the hose.

Now imagine the same garden hose feeding the same basin of water (the hose output submerged in it), only now, the water pressure at the supply side alternates between positive and negative (akin to alternately blowing into and sucking out of the hose). In this case, water would alternately travel down the hose and into the basin and back up from the basin into the hose and into the negative (sucking) water pressure source during each repeating cycle.

As already noted, a rotating dynamo inherently develops an alternating, or AC, voltage across its rotating coils, not a DC, constant voltage. The DC voltage which appears at the output of a direct current machine is artificially produced by an electro-mechanical switching mechanism within the generator called a commutator which automatically reverses the polarity of the rotating coils on the armature as they rotate in such a way as to produce a voltage at the output terminals which is essentially “direct” (unipolar and roughly constant in value over time).

Can AC and DC each be used for electrical power?

Yes, AC as well as DC electrical current can deliver useful electrical energy to a compatible electrical load… like a light bulb or a toaster!

What would not constitute a “compatible” electrical load?

Here, is the crux of our story: In 1879, the year that Edison’s practical lightbulb materialized, the only electric motors in existence required DC power. While AC could be used to power Edison’s light bulbs, no electric motors existed which could run on AC power!

The absence of motor designs at the time that could run on AC power steered Edison and others in the direction of DC for power generation and transmission in their proposed central power stations; this decision proved to be extremely unfortunate for Mr. Edison!

Enter Nikola Tesla, Electrical Engineering Genius;
Tesla’s AC Electric Motor Is Developed in 1887

Oft-times, one is tempted to revert to the expression, “Fact is stranger than fiction: you just cannot make this stuff up!” Nikola Tesla illustrates the truthfulness of the contention. Often called, “the master of lightning,” Tesla displayed levels of imagination, creativity, personal eccentricities, and electrical genius never-before seen in the long history of technological progress.

Tesla sits amid extremely high voltage electric discharges in his laboratory!

Whereas Thomas Edison famously claimed that, “Inventive genius is one percent inspiration and ninety-nine percent perspiration,” Nikola Tesla’s greatest inventions came to him in meditative, “dream-like” states of consciousness while his mind was set free to roam. Striking, indeed, were the differences between the men, their methods, and their personalities. Tesla revealed that not only new ideas came to him in these mental states, but detailed implementations of these ideas materialized in his mind’s eye as well. There is one other striking contrast between the two men to be highlighted: although Edison ultimately lost big in the “AC/DC current wars” with Tesla and his industrial partner, George Westinghouse, Edison died a rich and very famous man. Tesla lived his last years in virtual poverty, penniless and forgotten by the general public, yet it was he who revolutionized electrical power engineering at the peak of his fame, and it was he who determined the future implementation of America’s power grid in partnership with industrialist and Edison competitor, George Westinghouse.

Tesla Arrives at Castle Garden, New York, in 1884 with a Letter of Introduction to Thomas Edison and Four Cents in His Pocket.

In spite of being an immigrant, “fresh off the boat,” Nikola Tesla was very familiar with the international reputation of his then-hero, Thomas Edison. Soon after arriving in New York, Tesla appeared before the great man in Edison’s offices at the Edison Electric Light Company, 65 5th Avenue. In hand, was a letter from one of Edison’s important associates in Paris, one Charles Batchelor. In the letter of introduction Batchelor had penned to Edison on Tesla’s behalf, he wrote: “I know two great men and you (Edison) are one of them; the other is this young man.” Most likely Edison viewed the young man standing before him with considerable skepticism: he undoubtedly thought Batchelor’s favorable comparison of this youngster to his accomplished self to be a rather large stretch, but Edison did need an engineer to help with myriad electrical problems he was dealing with at the time. Tesla was quickly employed by Mr. Edison, his hero, and was floating on cloud-nine.

It took barely one year before Tesla walked away from his position after some questionable re-negging on incentive bonus promises Edison had made to the young engineer who had performed superbly enough to earn them. Nor was it helpful to the relationship between the two men that Tesla was speaking forcefully about his visions for AC current electrical systems as opposed to DC systems in which Edison was already heavily invested. Also invested and looking over Edison’s shoulder was J.P. Morgan, the banker/financier who had an uncanny nose for financial opportunity. As one of Tesla’s biographers expressed the situation, when Morgan invested in a fledgling venture, the venture quickly became “Morganized,” meaning subject to very close scrutiny and a 51% controlling share for Morgan – considerable pressure for any entrepreneur!

The year 1887/88 found Tesla employed digging ditches – for Edison’s New York underground electrical transmission lines. The labor was hard…and demeaning for the proud young man who arrived from Serbia with such a solid technical education and such supreme confidence in his own abilities. During this trying period, he wondered if all his years of schooling were wasted when contemplating the practical, real-world financial successes of Edison, his former boss and hero, who had barely the semblance of a grade school education.

During this period, Tesla pursued his electrical visions and was issued seven patents; such accomplishments paired with his ever-active intellect began to attract attention and backing for the new Tesla Electric Company, located at 33-35 South 5th Avenue – literally just down the street from Edison’s offices. Quickly, Tesla began filing patent applications on no less than three complete AC power systems and their requisite electrical components: AC dynamos, AC motors, power transformers, and various automatic controls. Working feverishly day and night, it took Tesla but a matter of months to transfer his long-held mental images for these components into solid patent applications. The sudden blizzard of tremendously important patent filings was quite unlike anything the patent office had ever seen.

Wall Street and academics quickly became aware of these patent activities, and, soon, an invitation came for Tesla to address the prestigious American Institute of Electrical Engineers. On May 16, 1888, he delivered his presentation, “A New System of Alternate Current Motors and Transformers.” The lecture was received with widespread acclaim and was soon referred to as a “classic,” both in style and substance.

The Nikola Tesla/George Westinghouse Alliance Is Formed

At this time, there were several companies tinkering with the possibility of AC power. Most of these were small start-ups (or upstarts, shall we say). One of the serious players was The Westinghouse Electric Company founded by its namesake, George Westinghouse. Westinghouse immediately recognized the newly assembled technical mother lode of Tesla’s mind recently put to patent-paper. The industrialist made an offer to license the inventor’s patents. For his forty patents, Tesla received $60,000 – $5000 in cash and the remainder in Westinghouse stock. In addition, Westinghouse reportedly agreed to a mind-boggling offer of a $2.50 royalty to Tesla for every horsepower of electricity sold by the company. A few years later, when Westinghouse Electric found itself in financial straits due to market conditions and its heavy, up-front investment in AC electricity, Tesla supposedly agreed to help save the company by canceling the royalty agreement.

In less than a decade from that point, Tesla would have personally made millions of dollars in royalties which Westinghouse was at least morally obligated to pay per the original “agreement.” The reputed royalty situation may have literally been a “gentleman’s agreement,” originally. A modern Westinghouse historian states that there exists no written record of a legal, binding agreement and goes on to say that such royalties would, today, have been worth trillions of dollars to Mr. Tesla’s estate! The episode, whether true or not, does reflect Tesla’s disregard for money for money’s sake. The personal, intellectual satisfaction garnered from the success of his ideas was a far more valuable currency to Tesla than greenbacks!

George Westinghouse, the industrialist, was necessarily far more pragmatic about money matters than was his brilliant associate (discounting the aforementioned royalty “agreement”). Nonetheless, he was an honest broker with his Westinghouse employees and truly cared about them. Any patent granted within his company had the originator’s name on it. Patents granted to Edison’s companies based on the work of an individual employee invariably carried the name, “Thomas A. Edison.” George Westinghouse was not only the antithesis of the great industrial “robber barons” of the age, he was a dedicated husband and family man, as well – a decided distinction in such circles.

The Vicious AC/DC Current Wars:
Westinghouse Versus a Ruthless and Desperate Edison

The marketing battle waged between Westinghouse and Edison to win the favor of industries and public opinion was quite unlike anything ever seen before – and possibly since. The Tesla/Westinghouse alliance touted the logic and superior efficiency of the AC system as reasons why it should be the roadmap for America’s future power system. As events unfolded to his disadvantage, Edison proceeded to employ scare tactics through advertising in order to convince the public that the high AC voltages carried in the Westinghouse transmission lines posed a danger to the unwary public. Electricity seemed a mysterious entity to most of the public at the end of the nineteenth century, and fear of the unknown always sets a high bar. The fear of being electrocuted in one’s home while changing a lightbulb or making breakfast toast was palpable to much of the uninformed public, and Edison worked to capitalize on those fears.
Animals were electrocuted outside of Edison’s West Orange, New Jersey, laboratory in staged, public executions using high-voltage AC current to emphasize the supposed danger inherent in the Westinghouse system. The concept of capital punishment using a high AC voltage “electric chair” was the by-product of another campaign waged by the low-voltage Edison capitalists.

Edison was fighting a losing battle all along, as he likely soon realized after Tesla began his one-year tenure with Edison after arriving in New York.

Here is a brief outline of the Tesla/Westinghouse system of AC power generation and transmission which won the day and doomed Edison’s DC system after the latter had blown much capital and waged his vicious, but losing campaign against the Tesla/Westinghouse system:

-A (typically) steam-powered AC dynamo generates a moderate to low AC voltage (let us say 115 volts) at 60 cycles per second.
-The dynamo feeds a step-up transformer which boosts the voltage by an arbitrary factor, say 50X, resulting in 115 volts times 50 = 5,750 volts!
-The resulting higher voltage/lower current equivalent power is fed to the transmission line which can now be constructed of lower current-capacity (smaller diameter) copper conductors, thus minimizing voltage-drop (and power loss) in the line.
-At the “load” end of the line, step-down transformers reduce the line voltage by the original factor of 50 which makes 115 volts AC safely available to homes and businesses. Note: the step-up/step-down process occurs with minimal power loss.

After his tremendous accomplishment of quite single-handedly visualizing, designing, and birthing hardware for the master template of America’s future power grids, Nikola Tesla moved on to what, for him, were still more interesting and challenging endeavors.

One of Tesla’s long-lived and stubborn visions involved the wireless transmission of significant levels of electric power over long distances using the earth’s ionosphere as a conductor/conduit. In middle age, he relocated to Colorado and carried on his investigations into ultra-high voltage and wireless transmission utilizing the tower-dome of a specially designed and constructed laboratory. Among the many inventions for which Tesla justifiably claimed at least partial success and credit was a “death-ray” which could immobilize and destroy most anything in its path. The so-called “star-wars initiative” which President Ronald Reagan touted during the cold war with the Soviet Union was based on a satellite system of laser/death-rays in space, reminiscent of Tesla’s vision.

Upon Tesla’s passing in 1943, the U.S. military classified some of his work, and portions of it quite possibly remain classified, to this day.

The Personal/Mystical Side of Nikola Tesla:
Writing This Post on the Man

Nikola Tesla was the quintessential loner – a man who never married and a man who traveled through life with few close friends. He was entirely immersed in and consumed by the gyrations of his imagination and the work necessary to implement his far-reaching visions. The more one learns about Tesla, the greater is the intrigue that settles-in. I began this post with the intent of profiling him and his importance to technology in several written pages; I soon found myself right here, already on page eleven of this document, yet with much left to say in my efforts to convey the uniqueness of the man and his impact on society.
Those who knew him well, and they were few, recalled an earnestness, an old-world gentility, and a sweetness in his persona that does not usually pair with the notion of an edgy, narcissistic loner. At the height of his considerable fame and powers after the resounding successes of the Westinghouse system at Chicago and Niagara Falls, he became quite the celebrity and did allow himself to enjoy the spotlight for a time. He was courted by the rich and famous, became friends with the Astors and the Vanderbilts and was pursued by society women. Although never married, he appears to have had a definite attraction to the feminine mystique; he certainly enjoyed female companionship at that time in his life, yet he related that any serious relationship would have been incompatible with his driving ambition and the need to devote full time to exploring and implementing his personal visions.

As a young man, Tesla viewed the proper role of women as life-partners to men, to be respected and cherished for their role in a collaboration which implements God’s plan for humans. In his youth, Tesla expressed doubt that he could be worthy enough for a young woman, but in later years he wrote against the trend in women’s liberation. In 1924 he wrote, “In place of the soft-voiced, gentle woman of my reverent worship, has come the woman who thinks that her chief success in life lies in making herself as much as possible like man – in dress, voice and actions. In sports and achievements of every kind…The tendency of woman to push aside man, supplanting the old spirit of cooperation with him in all affairs of life, is very disappointing to me.”
Despite his intense focus on technology and creative innovation, Tesla was very much a renaissance man, a philosopher with wide-ranging ideas on many fronts. Although he lived an ultimately isolated life, the image he projected was that of an extremely bright and informed man, impeccably groomed and dressed – fluent with a genteel personality and a noble, old-world bearing.

At the height of his fame, Tesla could be seen dining nightly at Delmonico’s, a fashionable and exclusive New York restaurant. He was there, at the same table every night, precisely at 8:00 pm, dining alone. He was indulged by the management with his own personal waiter and his required stack of freshly laundered napkins. Personal tidiness and cleanliness seemed rather an obsession with the man, to the extent of seemingly obsessive/compulsive behaviors.

Tesla’s Late Years – A Bittersweet Ending

Tesla’s passion to achieve the wireless transmission of electrical power levels (as opposed to weak radio signals, for example) led him astray beginning in mid-life. By his later years, potential investors lost faith in the halting progress and promise of his still-considerable efforts. The local establishments including hotels like the elegant Waldorf Astoria and, later, the New Yorker, catered to him initially as a steady, good customer. Later, when his money was gone, Tesla would be carried along with credit by some out of a charitable recognition of his earlier achievements and personal uniqueness. He became, in other words, a local fixture, a notable, easily recognizable, once-famous “character.” It appears that the Westinghouse Electric Company stepped in at one point and committed to help with Tesla’s support in recognition of his past importance to the company and his role in its history.

At the end, as Tesla’s mind dulled and his money was gone, his life and his passion became the simple, daily ritual of sitting in local parks and feeding his loyal friends, the pigeons.

Nikola Tesla died alone in his room at the New Yorker hotel on January 7, 1943, in New York City at eighty-six years of age.

There is a concluding section to this post which follows. If you have read this far and found the material interesting, I urge you to continue on, forsaking any natural fears of a few simple algebraic equations. Your reward: a layperson’s easy-to-digest understanding of the great Edison vs. Tesla/Westinghouse “current wars” and insight into the basic technology behind today’s vast electrical grid, a technological marvel not to be taken for granted. Let the primer begin:

Ohm’s Law: a fundamental precept of electrical science and engineering was central to the failure of Edison’s DC power distribution scheme; let us begin here to follow the logic of the Tesla/Edison “AC/DC current wars.” First stated by Georg Simon Ohm in 1827, Ohm’s law is taught on day-one in all beginning electrical engineering courses.

Ohms Law: V = I R

Easy digestible translation: Ohm’s Law declares that a voltage-drop, V, along a wire (or electrical transmission line) carrying an electric current, I, is equal to the current, I, times the electrical resistance, R, of the line. For any current conductor, the overall resistance of the line can be quantified and shown to become proportionally higher, the longer the conductor/wire (twice the length, twice the resistance). For long wires like electrical transmission lines which carry large current, the voltage-drop along the line can be significant, resulting in less voltage, hence less electrical power transmitted to the load at the far end of the line. Ohm’s law also tells us that for a given fixed source voltage (at the dynamo output, for instance), the voltage drop in any given line will be proportional to the current being supplied by the line to the load (twice the current, twice the voltage-drop).

Ramifications of Ohm’s Law on Edison’s proposed system of power stations:

-In order to minimize voltage-drop in the transmission lines between Edison’s proposed low-voltage DC generator stations and intended customers, Ohm’s law dictates that either the current to be transmitted and/or the line resistance must be kept low.
-A low current transmitted means lower available total power at the customer end. Therefore, fewer customers can be served by each power station/transmission line, and more power stations are required. This is not an economical system.
-A low resistance requirement for the transmission line (wires) would mean shorter runs between power station and customer (again, more stations required) and/or thicker, heavier wire which offers less resistance per unit length and proves to be more expensive and more difficult to install over long runs due to the greater weight. Note: twice the diameter of a given wire yields one-fourth the total resistance in the same length of line. Copper is among the best-known conductors of electricity, thus very desirable, but copper has become very expensive, today! Another comment: long runs of thicker, thus heavier, copper wire between power station and customer pose structural challenges and greater expense for the construction of transmission towers.

The simple equation for deliverable power (from station to consumer):

P = V I

which declares that the power delivered, P, equals the voltage supplied by the dynamo to the transmission line, V, times the current delivered to the load, I, (assuming zero power dissipated/lost in the transmission line resistance).

Note from the above simple equation that the same numerical power can be delivered at one-hundredth of a given current if the applied voltage is boosted by a factor of one-hundred times! Small-gauge transmission lines could then be used to save cost and to simplify their construction. There is a problem, however: dynamos (generators) that directly supply high voltages are difficult to implement and operate. A second problem: at the customer’s end, a high voltage at the wall outlets in one’s home would be very problematic from a safety standpoint!

What Is Needed? A “Magic Black Box”

If the inherently lower voltages generated by dynamos could be boosted by some arbitrary factor, say, 50X by passing them through a “magic black box” before being applied to the transmission line, half the problem would be solved. If another, “inverse magic black box” which reduces the voltage at the transmission line output by that same factor of 50 before being distributed to homes and businesses, such a system would be safe for the consumer, economical in operation, and a commercial winner with huge financial rewards.

Two key items had yet to appear in 1882 when the AC/DC current wars began and Edison had already fatally committed to DC power: practical designs for both AC powered motors and for high-power transformers.

An electrical transformer in its rudimentary form is simply a magnetically soft-iron core shaped like a doughnut with two electrically separate coils of wire wound around the core. One of these coils is the “primary winding,” and the other is the “secondary winding.” Although the two coils are electrically separate from one another, they are magnetically coupled together via changing magnetic fields in the doughnut core which are generated by voltage changes across the primary winding. If the voltage from an AC (alternating current) dynamo is connected across the primary winding, an AC output will appear across the secondary winding according to the following relationship:

secondary voltage = primary voltage multiplied by the ratio Ns/Np where

Ns is the number of coil-turns of the secondary winding and Np is the number of coil-turns of the primary winding.

The transformer and its magnetic induction principle were first demonstrated in 1831 at the Royal Institution of Great Britain by Michael Faraday, one of history’s greatest physicists and electrical experimenters. Faraday truly was the “father of the electrical age,” having built and demonstrated the first electric motor (DC, of course!), the first dynamo, and the first transformer. Faraday was first to envision electric and magnetic “lines of force,” paving the way for the foundational electromagnetic theories of James Clerk Maxwell. With less than a grade school education, Faraday ascended to the pinnacle of science. Only names like Einstein, Newton, and Galileo, rank higher. An interesting comparison comes to mind: what the barely-schooled Edison ultimately was to invention and technology, Faraday, with his minimal schooling was to research and science – only in spades!

 

 

 

 

 

 

       Faraday’s induction ring       Faraday’s diary entry: Aug. 29, 1831

Faraday’s diary entry of August 29, 1831 reveals the details of his discovery of the principle of electromagnetic induction. Faraday showed that a voltage could be induced in the secondary coil of wire by a changing voltage applied to the primary coil even though they are electrically insulated from one another. His critical observation was that an induced voltage in the secondary resulted only when the voltage across the primary coil was changing. An unchanging DC voltage applied to the primary coil produced no voltage across the secondary coil. It was not until decades later that transformer designs emerged which were capable of high-power operation at relatively low AC frequencies like 60 Hertz (cycles per second).

In Nikola Tesla’s eyes, the potential of a transformer design capable of high power operation was the green light for AC power stations and transmission systems. Such a device, in concert with his own AC motor patents, foretold the demise of Edison’s DC power schemes. Tesla not only had the foresight to see the complete big picture clearly, his detailed designs for the first practical AC motors and suitable power transformers led the AC power revolution. Tesla personally calculated the optimal AC line frequency of 60 Hz (cycles per second) which is used exclusively today in North America. The levels of insight, engineering, and formal mathematics required to visualize the ultimate system and to invent/perfect its necessary components all speak to Tesla’s genius and ability. Thomas Edison’s cleverness and his grade school education were no match for Tesla’s engineering credentials and genius in the AC/DC current wars. Mr. Edison was, sadly, way over his head in this arena.

George Westinghouse and the Westinghouse Electric Company had, by 1888, licensed Tesla’s AC motor, power transformer designs, and other auxiliary system components.

Here, once again to recap, is the short-form essence of the Tesla/Westinghouse system of AC power generation and transmission which won the day and doomed Edison’s DC system:

-A (typically) steam-powered AC dynamo generates a moderate to low AC voltage (let us say 115 volts) at 60 cycles per second.
-The dynamo feeds a step-up transformer which boosts the voltage by an arbitrary factor, say 50X, resulting in 115 volts times 50 = 5,750 volts!
-The resulting higher voltage/lower current equivalent power is fed to the transmission line which can now be constructed of lower current-capacity (smaller diameter) copper conductors, thus minimizing voltage-drop (and power loss) in the line.
-At the “load” end of the line, step-down transformers reduce the line voltage by the original factor of 50 which makes 115 volts AC safely available to homes and businesses. Note: the step-up/step-down process occurs with minimal power loss.

In the end, Edison had blown much of his own capital as well as investment money from the storied financier/banker, J.P. Morgan. What remained for Edison was the memory of both a failed system technology and a vicious, slanderous campaign against the Tesla/Westinghouse system.

Big “Wins” for the Tesla/Westinghouse AC Power System

Westinghouse outbid the Edison Electric Company for the rights to power the massive and important 1893 Chicago Columbian Exposition. A system of steam-powered AC dynamos was installed to power the Exposition and the thousands of lightbulbs supplied by the Westinghouse Electric Company. Westinghouse’s bid was far lower than Edison’s and, although perhaps not very profitable to Westinghouse, signaled a major triumph for the more efficient AC system over Edison’s DC proposal. Chicago proved to be a complete success for the AC system of Westinghouse Electric.

The success of the Westinghouse AC system in distributing power to the northeast sector of the United States from the newly harnessed hydro energy of Niagara Falls provided further and final credence to the early claims of Tesla and Westinghouse regarding the promise of AC power for the country.

The Final Strange Twist to This Story

As is often the case, technological innovation moves relentlessly forward and often changes the status-quo in strange ways. Recent decades and huge technological progress have produced electrical components and systems that now make the generation and transmission of extremely high-voltage DC currents feasible. Many selective portions of today’s power grid now transmit DC power over long runs using voltage levels of hundreds of thousands of volts. As pointed out in the preceding technical primer, high voltage and low current is the preferred balance for long distance power transmission. In the early decades, there was no way to accomplish this other than using AC, alternating current. Even so, the use of AC does impose secondary power losses in the system which can be minimized using today’s ultra-high-voltage DC transmission. So, in retrospect, Edison was accidentally prescient with his early DC proposals, yet he deserves no credit for his advocacy of DC in the “current wars” of his time. History has justly and amply rewarded Nikola Tesla and George Westinghouse for their engineering expertise, efforts, and conviction.

In Conclusion (For Anyone Still Standing):

I now find myself on page 21 of this post (the longest and most challenging of my many efforts on this blog), yet my efforts to portray the full story of the brilliant, eccentric visionary that was Nikola Tesla necessarily fall far short. Tesla’s many other innovations, his name, and his story have been largely forgotten more than once by the public at-large. Today, the Tesla automobile and the engineering unit for magnetic flux density, the “Tesla,” have kept his name alive. That is as it should be!

Greenfield Village, Michigan: Henry Ford’s Historic Legacy

Last month, Linda and I spent eight days vacationing in Michigan. We went there with two goals in mind: first, to see October’s fall colors minus busloads of New England tourists; second, to visit Henry Ford’s Greenfield Village. Greenfield Village can best be described as the personal passion and indulgence of one man, and that would be Henry Ford, one of history’s greatest industrialists and one of its richest men.

We stayed at Ford’s Dearborn Inn, a short walk from Greenfield Village and “The Henry Ford,” a vast and incredible museum – the indoor manifestation of Henry Ford’s personal desire to preserve the past and a reflection of his young world and the ideals he held dear. Henry Ford and his favorite motorcar, the ubiquitous Model T Ford, were driving forces behind the great mobilization of America at the turn of the twentieth century. Ford quickly became one of the country’s richest and most famous men. With both the means and a personal vision, Ford spent millions to create a living legacy to both the technology of his day and the way of life which invention and industrialization were busily changing… forever.

Greenfield Village is a concentrated restoration/recreation of many of America’s finest times and places. Thomas Edison’s famous research laboratory from Menlo Park, New Jersey, is faithfully recreated and, indeed, literally reassembled in the Village. The first viable electric light bulb was perfected in 1879…in this building!

Also present is the original bicycle shop brought from Dayton, Ohio, in which Orville and Wilbur Wright conceived and developed the first powered airplane. Their first successful heavier-than-air flight in 1903 ushered in the era of aviation.

A significant part of the Wright Brothers’ research into the controllability and sustainability of flight took place behind the storefront of the Wright Cycle Shop. Much of the activity and the equipment is beautifully displayed, here.

I was long skeptical, early-on, about the concept of Greenfield Village, visualizing it perhaps as a sort of historical Disneyland creation. Once there, I was pleasantly surprised to learn that Henry Ford was maniacally dedicated to authenticity and to preserving as much of the original buildings and artifacts as humanly possible. The original buildings restored/recreated here were literally disassembled by teams of Ford workers on their original, distant sites, packed and crated, and shipped at great expense to Dearborn on the way to their final resting places at Greenfield Village. Greenfield represents Henry Ford’s fervent devotion to authentically preserving a way of life which, perhaps sorrowfully, he realized would be unalterably changed by the industrialization and modernization for which he, as much as anyone, was responsible.

Mr. Ford, it seems, realized early the undeniable fact that tangible property and historical sites, no matter how important, were doomed to succumb to “progress” unless privately owned, funded, and maintained. As Linda and I strolled from attraction to attraction and learned from the docents inside, I came to realize the wisdom in Ford’s contention. Yes, it would be wonderful if Edison’s famous research laboratory still sat beautifully preserved on its original site in Menlo Park, New Jersey; the same can be said of the Wright Cycle Shop in Dayton, Ohio. The odds against that being the case were always practically zero in a society which is ruled by money and which too often looks forward and, almost never, backward to absorb the lessons and wisdom inherent in historical perspective. To his great credit and our good fortune, Henry Ford understood and acted by leaving us the next best thing.

Thomas Edison and Henry Ford: Kindred Spirits

The influence of Thomas Edison is seen throughout Greenfield Village. Like Edison, Henry Ford had little formal education. Ford also realized two facts at an
early age: one, that he could never be happy following his parents as farmers; two,
that he had both an interest in and an aptitude for things mechanical. In fact, as a young man, he went to work in Thomas Edison’s light bulb factory, becoming foreman in less than a year. Soon, Ford’s growing ambition to work on things strictly mechanical led him to begin pondering the possibility of building an automobile. Others had similar ideas, but no one else envisioned the automobile as anything other than a toy for the wealthy, let alone as a necessity for the average man. It was Ford’s vision and ingenuity which led him, quite literally, to “invent” both the notion and the process of mass production. His embodiment of that vision came with the Model T which was introduced in 1908. In a market where others sold their fancy automobiles for close to $2000, Ford was selling his down-to-earth, practical and reliable Model T for $650 – and you could get it in any color as long as it was black! Of course, the economics of the production line dictated a single color only at such a price, but Ford carried his analysis of production line realities far beyond the obvious. As one of the early practitioners of production line time-and-motion studies, Henry Ford had determined that black paint dried much more quickly than did other colors – a fact supported by scientific knowledge that explains the fact that black absorbs heat much more readily than lighter colors. One might counter that the difference would prove minimal, but one would be wrong given that multiple paint coats were applied. In fact, a light color such yellow or white would consume twelve times the total drying time in the Ford process than would black! I found that fact to be extremely interesting.

Thomas Edison and Henry Ford both placed a premium on ingenuity, common sense, empirical testing, and hard work as the primary ingredients of success. They also displayed an inherent distrust of venturing too far into scientific research and theoretical speculation. This alienation from advanced learning and engineering was to cause them both problems along the way, especially Edison who utterly failed in his massive bid to supply direct current electricity to the many minions who had bought his light bulbs before the turn of the nineteenth century. My next blog post will deal with that dramatic and extremely important story.

The marker adds: “Henry Ford greatly admired Thomas Edison.” It goes on to say that Edison sat for the sculpture during the last months of his life.

Another Edison site in Greenfield Village that re-kindled my interest as a retired electrical engineer was the reconstructed Edison “electric power station” which contains one of the original six DC (direct current) dynamos (electrical generators) used by Edison to power and illuminate several square blocks around Pearl Street in downtown New York in 1882. This Edison enterprise was the first “electric power station” in America. Despite its potential importance and the great hoopla surrounding its success in lighting a small section of downtown New York for several years, the enterprise along with Edison’s plans to corner the imminent American electrical market was doomed to spectacular failure.

As already mentioned, my next blog post will explore Thomas Edison’s losing battle in the electrical current wars waged between direct and alternating current to supply the nation’s immense power grid-to-be.

And I promise that no technical expertise will be necessary for you, the reader!
