Who Invented Three-Phase?

Tom, I thought you were just a kook, but clearly you are actually a shill! Shame on you!

Filled with cleverly slanted and subtle errors designed to mislead. Missing are facts like Tesla held major PATENTS on all his inventions. That he developed them in his own lab. That somehow his lab "mysteriously" burned down. I guess you'd have us believe is backers did it to "force him out". Westinghouse used TESLA's patents not the other way round. WESTINGHOUSE was being force out of HIS company until Tesla agreed to tear up their royalty contract (stupid business act I might add, but done as a good friend) The job Tesla was to do WAS well defined and Edison refused to pay. Tesla had a hard-on for Edison over that for YEARS and only under great pressure was persuaded to accept the "Edison Prize" by his friends because he didn't want it because it had Edison's name on it. Obviously, this is a quite different personality from the idea-stealing nut case you present in your "plausible" scenario. And in case you don't know Tesla holds all the first patents on "Westinghouse's" fluorescent lamps. And his parade of astounding inventions was the talk of the fair. (no doubt according to you all invented by Westinghouse...but then why does Tesla hold the patents on them all and not Westinghouse?)

Obviously you are one more lying debunker shill. What is it with Tesla that scares you power-elite so much anyway? Inquiring minds want to know?

J. P. Morgan said of Tesla: "Nobody milks my cow for free!"

Nope, you, have nothing worth paying for.

I worked (note the past tense) on a lot of surplus military equipment. I can't claim to have worked on them all. Regardless I would say that is an odd mg set and one that I have never experienced.

A lot of dynamotors were made for communications from military vehicles. There were literally tons of surplus units that were DC to DC to provide plate voltage for transmitters used on a jeep or a deuce and a half. You are describing a frequency changer, and 400 Hz wasn't used for ground communications. Also, 400 Hz wasn't common on the earliest planes, and it was used for things with power transformers, or to drive fixed speed motors.

The DC powered Dynamotors had a contactor that looked like an old Ford starter solenoid, but the coil was wound for continuous duty. That way they were only running when they were needed, to extent the useful life of the brushes and commutator. Mootrola, GE and other companies continued this practice with their vacuum tube base two way radios until the 'ate 60s or early '70s. They used a vibrator to power the reciver, and kicked in the dyneamotor when you pressed the transmit button on the microphone. That kept the radio from running down the battery in the vehicle.

It's easy to think outside the box, when you have a cutting torch.

What a marvelous argument. Nobody can comment on historical events because we weren't there. No need for history books (like biographies) unless they were written by people who were there?

Your "version on the Web" has no source given, and is what you "recall". It is blatantly wrong. Tesla was not involved with incandescent light bulbs. Read the many biographies of Tesla. If you think the web article might be right you are more uninformed than Potter.

I agree with benj that Potter gives a highly slanted view of Tesla. Potter has minimal accurate information on Tesla, and shares mostly his uninformed opinions.

Like for instance his early comment that "Tesla had a great respect for Edison" which is easily debunked - like benj's comments that Tesla didn't want to accept an "Edison Medal" from the AIEE (IEEE). (Potter changed his opinion on this one.)

Like Potter saying Tesla gained great advantage in his short time working for Edison. What advantage? Potter hasn't said.

Like Potters dismissive timeline slanted against Tesla (much of the information, but not slant, appears to come from Wikipedia).

I covered parts of Potters time line previously, but to pick one item > 1893 - Used Westinghouse's florescent lamps to entertain at the World's Fair.

Tesla invented fluorescent lamps. They were a novelty (not made by Westinghouse) in 1893. If Potter knew much about Tesla he would have read about Tesla's experiments and demonstrations with fluorescent (not florescent) lamps.

But far more important, Potter appears to have no idea how important the Columbian Exposition was in the history of electric power. It was the first major defeat of Edison's DC in the "war of the currents". And it was the first one heavily electrified including the first extensive incandescent lighting. Both of these were huge events. Potter appears to have no idea how important Tesla was in what happened electrically at the Exposition. And Tesla was a major figure at the Exposition and did demonstrations far beyond fluorescent lamps.

It is real easy to "beat up on Potter". His stated views are slanted at best, and largely wrong.

Not even speculating. I'm asking. DID TESLA DO THAT? Is Tesla responsible for the standard shape of all modern industrial motors? If it was done by some other designer, then I'm barking up the wrong tree.

s.

Dynamos, and large industrial DC motors. Which of course often are the same device but with differing small features.

ot, but that WAS a large problem of the age.

Go inspect photos of Edison's large DC dynamos.motors below. Before Tesla, they resembled huge horseshoe-shaped electromagnets. The rotor was installed in a gap between the horseshoe poles.

a8s9DUVnqVGXG46ux1

one creates a VERY inefficient "magnetic circuit".

Yes, one website even mentions that everybody back then "knew" that long magnetic circuits were best. If true, then it might take some actual courage to go against the industrial community.

Some unknown person came along and changed Edison's designs into compact, extremely short magnetic circuits. No more long horseshoes. Motors and dynamos became cylindrical.

This. Was this what Tesla did for Edison?

So, in that big tiff when Tesla walked off, was it because Edison refused to pay for the new breakthrough Edison product line which employed compact cylinders? (Yes, obviously short-magnetic-circuits, duh.)

I see lots of suggestive evidence but no hard facts so far. If it happened, then certainly Edison/GE wouldn't want such enormous glaring theft widely known. If it happened, then they must have spent decades quivering in their boots, knowing that Tesla could ruin them at any time with even a small negative publicity campaign. Don't follow only the money. Follow the bad publicity, follow the lawsuit fears, follow pathological human psychology exhibited by all the rapacious businessmen of the era.

Exactly.

Who else at the time was designing that way? Who else exhibited that insight?

Well, clearly this proves I have no understanding of physics. Nor of magnetic engineering, or manufacturing feasibility. And no experience in the "Insult and One-Upmanship" game played by students and ignorant noobs. [hey didjya see what he jus did ther]

Sheesh.

No, instead the short mag circuits are today obvious, and it goes without saying: Tesla knew exactly what he was doing physics-wise. But how would some other engineer produce such a design, if it had never been done before? It could be standardized to be a cube. Or a sphere. Or a hexagon. But Tesla seemed to employ cylinders and lathe-turnings in designs, almost to the point of fetish. (Go look at all his work. Perceive as sculpture, as beautiful as well as not only functional but efficiency-optomized to a superhuman degree. Then imagine what it all might resemble if a sphere-fetishist or hexagon- lover had designed it. Or even designed by a normal, non-superhuman engineer.)

Or maybe it was just that Tesla wasn't an electrical engineer, he was a mech-E, so he automatically produced easily-manufacturable products out of long habit; products which need no fancy milled parts, just a simple shop lathe and some iron castings. (Heh, iron castings produced from greensand and forms which were, um ...turned on a lathe, ha HA!)

:)

So a possible (but in no way certain) "Tesla Signature" is cylinders and lathe-turn shapes. Doesn't matter if this signature originates from mechanical engineering brilliance or hidden artistic imperitive. If you've studied Tesla, you've seen that his inner drive included both. His designs were all works of art. The prototype models could have appeared in sculpture galleries (I mean, before they were mass produced and turned into utterly common features of modern society.)

What discredit. I'm a Tesla worshipper and long-time amateur Tesla scholar. Still haven't been to Beograd though.

I'm asking, "Exactly what did Edison contract for, and then refuse to pay?" Verbal contract obviously. Perhaps even no handshake, if Tesla was avoiding cholera infection as his stated habit. Hmm, speculation: perhaps Edison was thinking all along in the following manner: "This foolish Tesla didn't shake hands, and then he trusted a verbal contract, and also I had my fingers crossed behind my back the entire time. That means I can refuse to pay, and the crime becomes all Tesla's fault, and my conscience remains clean."

idden there!

Which arrow specifically? The one I originated a few years ago, and just introduced in this thread? :)

PS Here's a motor design by another engineer. If this example below had been the one that started it all, then perhaps all modern motors would be rectangular blocks with rod-shaped electromagnet coils.

Nah, it's just another pseudoscientist. And probable newsgroup troll. When they try to attract argument, reward them with silence.

(But then also go off and privately "try on" his viewpoint. See if it assembles all the facts into a coherent whole, and offers new places which fit previously-discordant facts. If it doesn't work, then it doesn't work. But what if he's right? Ah, in that case the usefulness of his worldview will be obvious during your test. And you'll have to stop defending your original position, and go "join the enemy." It's only right. And the same goes for Potter: he should try on your viewpoint, and see if it forces him to drop his current defensive position and come 'join the enemy.' One drink from our Koolaide and he'd become a Tesla Worshipper.)

Pseudoscience: choose a position, then defend it. Remember, the only goal is to win.

Science: choose no position, instead become a permanent fence- sitter, and always keep testing for new insights by "trying on" many different viewpoints (even opponents' viewpoints.) The only goal is to understand.

It seems to me that the rational, intelligent, moral way to approach a dichotomy is to address the points in contention, rather than editorializing about the messenger.

As I quoted from Tesla own autobiography: "Then came another event. I met Edison, and the effect he produced upon me was extraordinary. When I saw this wonderful man, who had had no theoretical training at all, no advantages, who did all himself, getting great results by virtue of his industry and application, I felt mortified that I had squandered my life."

As can be seen, Tesla worked for Edison a few months, and in less than a year found investors and formed a company using his own name, and applied for a patent on an arc lamp, much like the one patented by Edison earlier.

No doubt, many immigrants would find it ADVANTAGEOUS to migrate to America, get a good job with the top technical lab, piggyback on the reputation of the lab and learn what products being worked in the lab, and find backers to finance a company for him.

"The Geissler tube[1] is a glass tube for demonstrating the principles of electrical glow discharge. The tube was invented by the German physicist and glassblower Heinrich Geissler in 1857. The Geissler tube was an evacuated glass cylinder with an electrode at each end. A Geissler tube contains one or more of the following rarefied (thinned) gasses, such as neon, argon, or air; mercury or other conductive liquids; or ionizable minerals or metals, such as sodium.

"Thomas Edison briefly pursued fluorescent lighting for its commercial potential. He invented a fluorescent lamp in 1896 that used a coating of calcium tungstate as the fluorescing substance, excited by X-rays, but although it received a patent in 1907,[4] it was not put into production. As with a few other attempts to use Geissler tubes for illumination, it had a short operating life, and given the success of the incandescent light, Edison had little reason to pursue an alternative means of electrical illumination. Nikola Tesla made similar experiments in the 1890s, devising high frequency powered fluorescent bulbs that gave a bright greenish light, but as with Edison's devices, no commercial success was achieved."

Considering that Westinghouse won the bid to illuminate the Columbian Exposition, and exhibited many AC systems and devices no doubt it gave a great impetus to switching over from DC to AC, but the people at the Edison companies were not stupid, and it was just a question of time until they switched over to AC for the generation and transmission of electrical power.

"By the 1870s, efficient generators that produced alternating current (alternators) were available, and it was found that alternating current could power an induction coil directly, without an interrupter. In 1876, Russian engineer Pavel Yablochkov invented a lighting system based on a set of induction coils where the primary windings were connected to a source of alternating current and the secondary windings could be connected to several "electric candles" (arc lamps) of his own design.[5][6] The coils Yablochkov employed functioned essentially as transformers.[5]

In 1878, the Ganz Company in Hungary began manufacturing equipment for electric lighting and, by 1883, had installed over fifty systems in Austria-Hungary. Their systems used alternating current exclusively and included those comprising both arc and incandescent lamps, along with generators and other equipment.[7]

Lucien Gaulard and John Dixon Gibbs first exhibited a device with an open iron core called a "secondary generator" in London in 1882, then sold the idea to the Westinghouse company in the United States.[8]"

"There had been considerable conflict between Edison and those who supported the claims for alternating current. The Thomson-Houston Company and the Westinghouse Electric Company had extensively developed this field for series electric lighting and arc lighting before the Tesla power system was developed."

Regarding the following Urban Legend: "One of the requirements was that Westinghouse get rid of the contract with Tesla calling for royalty payments of $1 per horsepower on all alternating-current articles sold under his patents. (No documentary evidence exists concerning this contract.)"

Let's assume that a company like Westinghouse did make a stupid deal like this, and they were planning to develop and sell products that involved billions of horsepower. Obviously they would cancel development, production and sales in this area if they could not come to a sensible arrangement. Westinghouse was making lots of money with his air brakes and other inventions, and why would he promote products where ridiculous royalties would destroy his company?

The Edison companies didn't need Tesla patents to become successful, and nether did Westinghouse.

"A high-voltage, direct current (HVDC) electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current systems. For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses. For underwater power cables, HVDC avoids the heavy currents required by the cable capacitance. "

The bottom line is that at points in time, there were advantages to DC, and there were advantages to AC.

Considering that many bright people like tj frazir and Tesla promote their ideas, rather than become a cult member, I suggest that people should invest their time and money in the ideas of these people, rather than worship them.

As Tesla's patents have expired I suggest that members of the Tesla Cult should invest their money in some Tesla projects like beaming power from generators to users.

Perhaps if the messenger wrote something that was related to reality.... And perhaps you missed - I addressed the points in contention.

Anyone with much knowledge of Tesla knows of his dislike, not respect, for Edison. Maybe you could read Wikipedia.

Cite someone who agrees with this nonsense. Another of your wild opinions.

They are the forerunner of "neon" tubes, not fluorescent tubes. Not even a good try.

What a wonderful device an x-ray activated fluorescent tube would have been.

Tesla did not commercialize a number of inventions. In your theory did he learn that from Edison?

The person at Edison Electric that counted was Edison. Edison Electric fought AC in the "war of the currents". Maybe you could find out something about it.

Check out who funded some of the research on the (AC powered) electric chair. (Electrocuting dogs, cats, an elephant, ....)

Irrelevant. Tesla did not invent transformers or AC (I never said he did).

But another of the major events in electric power history was the 112 mi transmission of high voltage AC power to Frankfurt Germany in 1891. It was 3 phase. Did I mention Tesla invented multi-phase? (Others have.)

Missing cite. Extensive? Hardly. Westinghouse was becoming extensive, but they had induction motors. It was not until Thompson-Houston and Edison Electric merged to General Electric, with Edison gone, that the remnant of Edison Electric was interested in AC. Thompson-Houston was one of the many companies that infringed on Tesla's induction motor patents.

Cite. It is well established. It was not $1. Did you make the quote up?

Westinghouse had controlling patents for ALL forms of induction motors. Apparently you are smarter than Westinghouse was - you would have canceled the monopoly on induction motors to give it to someone else. What foresight!

One of the reasons for Westinghouse Co. problems before the royalty cancellation was their insistence on using 133 Hz (if I remember right). When they shifted to 60 Hz (which is what Tesla wanted all along) the motors worked.

Any company needed Tesla patents to build induction motors. Why do you suppose so many companies infringed on Tesla's patents? Where is the practical non-induction motor competitor?

High voltage DC was not remotely possible when the "war of the currents" was going on.

The question is what Tesla contributed. Why did many companies infringe on Tesla's induction motor patents? Where are the DC motors that successful competed with induction motors? Why did AC win the "war of the currents" to be used at the large hydro plant at Niagra falls (another of the huge events in electric power history)? Why are we using 3-phase?

I suggest you invest time finding out about Tesla. I like to see accurate information in sci.newsgroups. You still have not posted much.

Oh yeah. Perhaps the first i saw was a repurposed one in the trunk of a car of an armature radio enthusiast. IIRC it powered a 500 watt 6/2 m mobile rig. Must have been about 12 at the time. Actually fiddled with a few over the next years, haven't seen any more since i graduated HS.

?-)

I am sadden to see that my pal William J. Beaty appears to have made me the target of his effort to rationalize his position on Tesla.

As a guy who owned several headhunting firms, and interviewed thousands of people, and analyzed tens of thousands of resumes,

it has been my experience that stable people, who have made many contributions to society over an extended period of time, can be trusted more than nuts, con men, charlatans, freeloaders, etc.

No doubt, Tesla, like tj frazir had a few good ideas, but this does not put him in the league with Edison, Westinghouse, Ford, Carnegie, Newton, Maxwell, etc.

It has also been my experience that creative and productive people like Edison, Westinghouse, Ford, and Carnegie honor and respect creative, productive people, and try to avoid people who waste their time and money.

The do everything they can within reason to keep productive people, but tell time wasters to not let the door hit them on the a$$ when they leave.

Note that Tesla worked only a few months for Edison, and soon after he left, he had a company in his name, and had applied for a patent on an arc lamp, much like one Edison had already patented.

Also observe that Tesla plays the intelligent "virtuous victim" role and blames all of his failures on Edison, his backers, Westinghouse, fate, etc.

I suggest that an immigrant that comes to America, works for Intel, Microsoft, Google, etc. for a few months, and sets up a company in his own name and patents a product similar to his employers would not be in the same league with Edison, Ford, etc. even if he had a few good ideas like tj frazir and Tesla.

As the Tesla patents have expired. I suggest that Tesla cultists should invest their time and money in some of his projects like the beaming of electrical power from power plants to users.

Very good analysis by both Benj and William J. Beaty.

The facts are, Tesla worked for an Edison company in Europe, came to America and worked for Edison for a few months, and within one year had found backers and formed a company in is name, and applied for a patent on an arc lamp, similar to one that Edison had patented and dropped work on probably because he didn't like the kind of light it produced.

Also note, that in his autobiography, Tesla makes the EXCUSE that he left Edison, NOT to form his own company,

but because an unnamed Edison supervisor promised him $50,000. to solve some unnamed problem.

Here's a question for all of you guys working for the government or big companies:

"If your supervisor told you he would give you $1,000,000.00 to solve some problems, would you take his word for it, or get it put on paper or witnessed by co-workers?

No doubt Tesla, like tj frazir, had a few good ideas, but to me he appears to be a greedy ( For fame and fortune) unstable, egotist, who made all kinds of claims and excuses.

IF anyone thinks that he was way ahead of his time, I suggest that as his patents have expired, that they invest their time and money on some of his undone projects.

Okay, let's review Tesla's activity chronologically.

--------------------------------------------------

1882 - Gets a job with Edison's Paris branch. 1883 - Has a mental breakdown. 1884 - Nikola Tesla arrived in New York on June 6, 1884, 1884 - got a job with Edison. Worked a few months until he found a backer.

Tesla files patent on Arc lamp Jul 13, 1885 and assigned to

***Tesla Electric Light and Manufacturing Company***

I wonder how Google, Microsoft or Apple would feel if they hired an immigrant, and within one year he had found backers, formed a competing company, and go a patent on something they already had paens on???

( Edison filed a patent on the arc lamp 10 Jun 1884. )

It is more likely that Tesla picked Edisons brain, conned some people into investing what would be millions of dollars today in his company.

No doubt Tesla had a few good ideas, but he was not in the same league as Edison and Westinghouse.

Edison and Westinghouse were in touch with what the market needed, and what was possible to deliver.

Observe that Edison's 1500 patents dealth with real world needs and real world state of the art.

Some of his patents include the phonograph, moving pictures, the arbon microphone. numerous patents to create power generation and distribution, numerous telegtaph patents, etc. amd of course, the "Edison Effect" patent that lead to the diode, the triode, and on to the transistor.

Some of Westinghouse patents include: grain and seed winnowers improvements in steam engine and pump improvement in atmospheric car-brake pipes improvement in steam-power-brake couplings improvement in valves for fluid brake-pipes improvement in fluid-pressure brake apparatus fluid-pressure regulator electrical converter system of electrical distribution system for the protection of railroad-tracks and gas-pipe lines fluid-meter fluid-pressure automatic brake mechanism alternating current electric meter fluid-pressure automatic brake switch and signal apparatus pipe-coupling conduit electric railway draw-gear apparatus for cars electric railway current-collecting device for railway-vehicles elevator electric railway fluid pressure automatic brake draft appliance for railway cars draw-gear and buffing apparatus electric railway system draw-gear and buffing apparatus automatic fluid pressure brake apparatus gearing

"Westinghouse was born in Central Bridge, NY in 1846. He was the son of a machine shop owner and was talented at machinery and business. He was only

19 years old when he created his first invention, the rotary steam engine.[1] He also devised the Westinghouse Farm Engine. At age 21 he invented a "car replacer", a device to guide derailed railroad cars back onto the tracks, and a reversible frog, a device used with a railroad switch to guide trains onto one of two tracks.[1][2]

At about this time he witnessed a train wreck where two engineers saw one another, but were unable to stop their trains in time using the existing brakes. Brakemen ran from car to car, on catwalks atop the cars, applying the brakes manually on each car.

In 1869 at age 22 he invented a railroad braking system using compressed air. The Westinghouse system used a compressor on the locomotive, a reservoir and a special valve on each car, and a single pipe running the length of the train (with flexible connections) which both refilled the reservoirs and controlled the brakes, applying and releasing the brakes on all cars simultaneously. It is a failsafe system, in that any rupture or disconnection in the train pipe will apply the brakes throughout the train. It was patented by Westinghouse on March 5, 1872. The Westinghouse Air Brake Company (WABCO) was subsequently organized to manufacture and sell Westinghouse's invention. It was in time nearly universally adopted. Modern trains use brakes in various forms based on this design."

Tesla is the Poster Boy of people who try to smear Edison because he was Henry Ford's best friend, and Henry Ford quickly recognized that the gang that massacred the Russian Family and co-opted the Russian government, were using Russia as a base from where to train terrorists and instigate the Class Wars of the 1900's.

Observe that the Edison companies did not need Tesla's patents, and for that matter, neither did Westinghouse.

In order to rationalize leaving Edison in a few months and forming his own company to produce copies of the arc lamp that Edison had patented and discarded because the light was lousy, Tesla CLAIMED that an unnamed Edison supervisor promised him $50,000.00 to solve an unnamed problem.

Tesla, like tj frazir, had a few good ideas, and many impractical ideas but his main claim to fame is that he is the Poster Boy for Edison haters.

It is interesting to see that although Marconi was awarded the Nobel Prize for his work in radio, that in 1943 when America was at war with Germany and Italy,

"Tesla's patent (number 645576) was reinstated by the U.S. Supreme Court shortly after Tesla's death, because prior art existed before Marconi's patent was established..the decision may have let the U.S. government avoid paying damages that the Marconi Company was claiming for use of its patents during World War I.."

and that the U.S. govenment confiscated billions of dollars in assets of Germany and Italy, ( And from American citizens of German orgin.) and nulified patents worth trillions of dollars.

Also note that Telsa's patent was basically a patent to transfer electrical power by brute force, high voltage, CONDUCTION through the air from a source to users.

And note that many people had developed devices to generate high voltage before Tesla began to play around with high voltage generators, and of course, many people had developed motors, generators, transformers, etc.

"Nicholas Callan was born on December 22, 1799, at Darver, near Dundalk. He was destined for the priesthood from an early age, serving as an altar boy and Mass server before he started his priesthood at Navan seminary. He entered St. Patrick's College, Maynooth in 1816 where one of his teachers was Dr. Cornelius Denvir, who got him interested in the emerging sciences of electricity and magnetism. In 1823, after his ordination, he went to study in Rome where he was intrigued by the work of Galvani and Volta, two of the key pioneers in the study of electricity. In 1826, Callan returned to Maynooth after being appointed to the chair of natural Philosophy (the old name for Physics).

In 1836, Callan had his major breakthrough: the induction coil. He took a horseshoe shaped iron bar and wound it tightly with thin insulated wire, then loosely wound thick insulated wire over the top. He discovered that when he interrupted the current sent through the thick wire (primary coil), a high voltage current was generated in the unconnected thin wire (secondary coil). This is how a transformer works, going from low voltage in the first coil to high voltage in the second coil. Callan discovered that the faster that he interrupted the current, the bigger the spark. In 1837, he built a giant induction machine that could interrupt the current 20 times a second. It generated 15-inch sparks at around 600,000 volts, and was the largest artificial bolt of lightning seen at that time. "

Tesla was more of a showman, like Callan, Barrum, etc. than a person who created great things for mankind, like Edison, Faraday, Ford, Marconi, etc.

I've heard this song and dance before. It's the standard Tesla- slamming "plausible" story playing on the fact of Tesla's occasional mental conditions to imply that therefore he was "insane" and we can totally ignore anything he did and any proof to the contrary can be safely ignored. Obviously such arguments are nothing but shill propaganda. The fly in the "plausible" argument is the hundreds of Tesla's patents.

More slanted bullshit. Just HOW many patents did Edison have (yeah he had more than Tesla, but is a book with more pages a superior book?), but how many did he steal from his workers who "didn't understand American humor"? How about Westinghouse? (about 30 patents) Then why did he have to license all of Teslas AC power distribution and motor patents if he was such a genius? How many did Ford have? Is 100 patents on the model T mostly developed by those in his plant one invention or many? Did Carnegie have any at all? Newton sure didn't. Nor did Maxwell. Who are you trying to fool here Potter? And more importantly, WHY? Your arguments totally fail because Tesla has HUNDREDS of patents for many of the MAJOR technical breakthroughs of the 20th century. RADIO! (lets compare to the MECHANICAL phonograph of Edison. He wasn't smart enough to invent the modern record player!) Tesla's inventions pretty much stand today as patented! Speedometer. Fluorescent light (NO, NOT "westinghouse" you moron!) Cripes and here is the ULTIMATE patent! Tesla invented AND PATENTED the AND and OR gate. TALK about achievement! How many patents do YOU hold, Potter? And how important are they? My guess is you patented dick warmers for the uncircumcised schlong.

Right. Lessee Edison stole everybody's work in sight, Westinghouse conned Tesla out of a Bill Gates level fortune in electrical AC patents, Ford of course was a HUGE anti-Semite so naturally you are kissing his feet, and it wasn't by chance they called people like Carnegie "robber barons"!

What we have here, Potter, is a listing by you of men known to have followed the common practice of the boss putting his name on all patents in his plant. In other words as usual, we have the Potter celebration of theft, of dishonor, criminal behavior and dishonesty. Not to mention the racist and bigoted actions so common in the age. No wonder you are getting wood, Potter. It's your HEROES we are talking about here.

Just WHO are you trying to fool and WHY are you trying to fool them and WHO is paying you to twist history so badly?

Inquiring minds want to know?

Conduction - how silly. Everyone knows transmission is through the aether.

Sorry, wrong again.

"Many people" did not develop induction motors. They could not be made without infringing on a Tesla patent.

With regard to wireless - Tesla's patent includes:

- tuning the transmitter and receiver to the same frequency

- using L-C circuits for tuning

- using a 1/4 wavelength length of wire

- connecting the transmitter and receiver between an antenna and earth

- "transmit intelligible messages to long distances"

With minimal knowledge of radio those elements might sound familiar.

You still have not posted much.

I see the opposite. The line between genius and insanity can be thin, and Tesla is a perfect example of that. He was a genius who, quite often, wandered back and forth over the line. We have much to thank him for.
