hey come on: "Contemporary researchers of Tesla have deemed him "the man who invented the twentieth century"[7] and "the patron saint of modern electricity."

DEFINITION

1. EDA        

a dumbass phrase uttered by the Fugliest, stupidest, darkest, brick-walled, dumbf*cks at a place in Garland, Texas . it literally means. hey you come here in a derogatory meaning. but these indians think its cool


As in "shrenik said KH EDA!!!!!"

As in "The city of Houston has this eda huwston f***** up!"

Dear Huwston

I would herewith like to advise you that Tesla was the dude who invented the spherical spaceship PLUS stealth techniques aka invisibility.

So, you go right ahead and show this page how misinformed and undiscerning you are and call Tesla a EDA as much as you like.  It does not alter the fact that he is one heck of scientist.

He was a VERY intelligent and capable person.  I need to research his mode of death.  Does anyone here know how, where and when he passed away (died)?  I am certain there were many scientists who were jealous or afraid of his inventions.

Tesla is totally overrated.  Many of the things he was supposed to have invented were invented earlier and some of the things he claimed to have have done are totally loony like lighting up 200 lamps without wires at a distance of 10 miles...back in about 1890?? 

3 phase AC was invented by John Hopkinson a bloke from Manchester.

Pumblechook, although Tesla was a very strange character, and bigger than life at times, he was it at a time and place where famous people were expected to be so:)

" Modern day transistor or vacuum tube Tesla coils do not use a spark gap. Instead, the transistor(s) or vacuum tube(s) provide the switching or amplifying function necessary to generate RF power for the primary circuit....

Tesla coils and other high-voltage electrical generators look spectacular but have no conventional use. At the same time, Tesla's induction motor—the core of the Tesla coil—is used in pretty much every kitchen appliance and household device, and the principles at work in the Tesla coil are used to create the high voltages needed for conventional television picture tubes to work.

Still, only two groups are doing much work with extremely high voltage electrical effects these days. First, there is the military, which has experimented for years with using ultra-high-amplitude electricity as a weapon. Second are hobbyists, amateur physicists, and adventurous people who want to share in what Tesla must have felt: harnessing lightning and chaining it to a machine."

I think you are crediting Tesla with the transformer effect, which Michael F discovered some time previously.

Electricity was NOT invented - it was discovered!

Tesla was ok in his younger days but as he got older in order to try and stay at the top of his game he made all sorts of ridiculous claims - a sad person really and it's a shame so many people hold him in high regard for his foolish
ideas rather than his real work.

First off what is an eda?, sorry for looking stupid but i dont deal in "speaking IM" like a 15 year old girl on a cell phone. secondly i am one of those people who holds mister tesla in extremely high regard, i would like to find notes on his experiments, but as we all know they were taken by the government as soon as he died (almost like it was planned or something) but anyway id like to perform an experiment having to do with using  electro-static repulsion to cause levitation, in theory ( and keep that in mind) focusing 2 or more seperate and alternate, extreme high frequency, rapidly
alternating electrostatic pulses onto a single point using electro magnets to focus the charge could cause a repulsion effect against the static in the air or ether as tesla theorized it, anyone interested in chatting it out? why it would work, why it wouldn't. I am just as nuts as tesla was and i love this kind of stuff, if i can get this kind of thing to work, id probably wet myself out of sheer surprise.

Please never use any Bad words against Tesla. He was a gem of a character. Just read wiki about him. He never married for the sake of man kind and also had chances to become the first billionaire in the world. However he was never business minded unlike Edison.

They were taken, yes, but then they sat around after the war until relatives in the USSR petitioned for their release.  Seventy steamer trunks of material were shipped out, and now form the collection at the Tesla Museum, Beograde Yugoslavia.

Also you can buy some of his notes:
"Nikola Tesla - Colorado Springs Notes"
"My Inventions"
"Inventions, Research, and Writing of Nikola Tesla"
"Nikola Tesla On His Work With Alternating Currents and their..."

Tesla was ok in his younger days but as he got older

Most of Tesla's later claims were essentially advertisments of his secret methods (without giving away the secrets,) as well as trolling for investors: "Here are the things I was planning to do before my funds got cut off.  Give me a few $100K and I'll start this up again."

If Tesla had a secret technique to light hundreds of light bulbs over many miles distance, we can insist that he was successful, or we can insist that he was misguided.  Bpth based on total ignorance, since we don't know what his secret method might have been.

Why cant we use his wireless electricity for generating light?

It's my understanding that there's no known primary source that he did this wirelessly.

It looks like this never happened. My understanding is that Tesla lit lots of lamps at a range of tens of miles, but this was a wired test, not wireless. It looks like this was conflated with his attempts at wireless power transmission at some point. It seems to have been an AC power transmission demo.

I recently found a documentary from him, very interesting! There are Dutch subtitles but I don't think it's annoying :)

As I tried to say..  Bloke lights 200 lamps 10 miles away in 1890 when equipment was primitive and knowledge shakey.  Yeah right.  And no-one can do it now with all the stuff we have now and much greater knowledge??

It's not completely impossible.

Off hand, you could probably do it wirelessly if you had several hundred miles of wire.

For example, if you did it with resonant transformers, the main trick is that the diameter of the coils have to be about 1/3 of the distance, so 3 mile diameter coils, 10 mile range.

Well,, it does work with a lot of energy wasted and the coils or aerials or whatever need to be a significant proportion of the distance you want to cover.  Wasn't some idiot at MIT pretending he had invented the idea and had 60 cm coils to cover 2 metres with 40% coupling plus significant 60 Hz to RF conversion losses and if he converted the RF at the receiving end to DC and them maybe 60 Hz would have further losses.  = WASTE of time and energy.   
Title: Nikola Tesla
Post by: wolfekeeper on 02/02/2011 03:07:11
30cm coils, and I think they did get slightly further distances than others had by running the frequency close to the diffraction limit for the equipment.

OTOH it unfortunately meant that they had more intense e-fields generated, and that meant that they failed the safety guidelines, for example, if they sat in the field for much longer than needed to take a photo, and it wasn't very practical in other ways either. AFAIK the productised versions would have to run at lower frequencies.

I don't think it was entirely a knock off of Tesla's tech; he mostly wanted to use capacitive coupling for power transfer anyway, although magnetic coupling over a rather smaller air gap was used IN his Tesla coils.
