THE Tesla Thread (merged)

I need to dig up my research notes on various Tesla devices. I keep thinking of it and never getting around to putting it all together. If anyone else is conversant in Tesla Technology, and you have all this at your fingertips, can you help me get started? Thanks.

This may seem like a ridiculous question so please beware.
As I recall Tesla was wanting to broadcast energy through the air (or ground?) for free and Westinghouse kindly said "are you f-ing nuts?". We are still surrounded by Teslas innovations so I have to wonder if that particular technology, as antiquated as it may seem, could be possible or for that matter if it has ever been proven? If so could it have a future? Come on, I know some of you educated peeps have a handle on this.

I think that tesla was using high-voltage high-frequency to transmit electricity through Earth. I don't know details about his "air" system. Transporting electricity this was is not very efficient, and almost any air transport (except perhaps lasers) means huge spread of energy and big losses. I would stick with our wires unless we develop cheap high-temp superconductors Smile

Allow me to clarify since I posted that after a twelve hour shift. If you'll scroll down to Wireless power on this page link there is a better description.
If you've never heard of Tesla here's the homepage. He was a pretty fascinating guy and I imagine you'd be amazed by the applications invented by him that are still in use. link

Some say that HAARP is part of what you are talking about: link This man was a genius.

I don't think we have any physicists or electronics engineers up to the task on this board....

I don't want to encroach into the conspiracy theory stuff either. Yeah HAARP probably does use it but, there's nothing I can do about it even if the technology does have the effects mentioned by various people.

My larger point, although no one bit on it, to some degree paralleled JohnDenvers Beam it Down thread. On the other hand if the technique mentioned actually works and the utility companies decided to go with a hard wired system to facilitate billing then they may soon change their minds due to the rising cost to mine copper.

As mentioned before mining for metals is a very energy intensive process. We move about 11 million tons a month for 23,000 tons of copper, a ratio of about 478:1. Energy cost have driven the cost per pound up about $0.30 over the summer which fortuitously (for me anyway) matched the rising price due to demand. To prognosticate, that won't break the bank but as this recession (if we are at the start) deepens the demand for copper will go down and, in the end copper will almost certainly reach a point where it is too costly to use as a common conductor for electricity due to rising energy cost. Barring the thirteen other minerals, everything from sulfur to molly to gold, another twenty cent rise in cost would make my current place of employment unprofitable. Seventy dollars a barrel and a rise in electricity should do it.

Supposing on a medium to soft landing, sucking electrons out of the air, as per Tesla, may be the only feasible way to transmit power; that is if it can be done and done safely. Could be that I place too much emphasis on raw materials since consumerism will probably take a dive anyway. To give a better idea of the meger amount of metal in the ore, here's an average assay. Ore grading 0.67% Cu, 0.027% Mo, 0.29g/t Au and 3.02g/t Ag, note the decimal points.

Anyway, here's a good account of what I was talking about. Is it myth or fact? "I was observing stationary (standing) waves.... Impossible as it seemed, this planet, despite its vast extent, behaved like a conductor of limited dimensions. The tremendous significance of this fact in the transmission of energy by my system had already become quite clear to me. Not only was it practicable to send telegraphic messages to any distance without wires, as I recognized long ago, but also to impress upon the entire globe the faint modulations of the human voice, far more still, to transmit power, in unlimited amounts to any terrestrial distance and almost without loss."

Is that what you were looking for EE?

I think there's also a website out there for "The Tesla Society" or some such.

Anyway, the guy was quite the genius. Gave us the polyphase AC system, and fractional horsepower electric motors. Those were the two big ones, there were many smaller ones.

For example a type of centrifugal pump that reles on two plain discs spaced a critical distance apart on the axle, with no "vanes" of the type normally found on the rotors in a pump. This is supremely efficient at handling viscuous liquids, and is commonly used in sewage treatment and chemical processing applications.

The guy would do all of his engineering design by visualization, and then instruct his technicians to build stuff based on the "blueprints" he kept in his head. And it worked. Today we routinely expect something similar (though perhaps to a lesser degree) from architects & engineers as a matter of routine, i.e. it's expected that people should be able to visualize in their design process. But when Tesla was doing it, it was considered a rare talent, because it was not something people were expected or taught to use.

Tesla's name is still around as a commercial brand. I have on my desk a telephone made in Czechoslovakia in 1969, and the nameplate on the bottom says Tesla in a circle with a waveform that peaks above the letter S.

As far as broadcast power is concerned, I don't find the idea particularly crazy; conceptually it's nothing more than scaling up what already occurs with radio transmission, the application of the principle of resonance, to in essence turn the earth/sky into a great big capacitor.

Problem is, it would be an ecological nightmare. It would at minimum transfer vast amounts of energy to the atmosphere, or at least to the clouds and other moisture present in the atmosphere (i.e. not all the energy going in, comes out: some of it is dissipated by the transmitting medium in the form of heat, much as with copper wires, but distributed throughout the particulates and moisture in the atmosphere). It would thereby have unforeseeable effects on weather and probably on long term climate. It would certainly interfere with the magnetic component of bird migrations (which in turn affect bird population distributions, which in turn affect insect pest populations, which in turn affect the human food supply and infectious disease propagation). It might have other effects on various plant and animal species, including humans. So while Tesla gets points for having thought of it, it's not something we'd want to do.

Broadcast power might be something we want to use on a very limited scale for localized applications, e.g. continuous slow recharge of the batteries on a search-and-rescue robot in an inaccessible space, or something like that. But the need would have to be sufficient to justify the potential ambient hazards. [/b]

Thanx gg, I knew someone had the knowledge. To bad about the atmospheric effects, a life without overheads could be beneficial in many ways.

I read all those links.. seems lie TESLA invention was 20 times more efficient. Why dont we do any of the things he purposed... or at least re-create some of his inventions??

gg3 · Posted: Mon Oct 04, 2004 5:56 am Post subject:

Yamaha, which Tesla invention was 20x more efficient than what? And yes, there are people who are resurrecting various of his inventions.

If I'm not mistaken there is another motor design that didn't go into commercial production at the time, but would be promising for various reasons (presumably efficiency) today. I recall folks in our R&D org talking about "the Tesla motor" at one point, and something else to do with an AC generator that could be adapted to wind turbines and produce a stable output more efficiently than the present mainstream technologies allow.

As far as the resurrecting of old inventions is concerned, consider that A.G. Bell also invented the hydrofoil, but the attention paid to the telephone kept him busy enough that the hydrofoil didn't get too far for well over 50 years. Presently it is becoming a standard in terms of increased efficiency of ferries and similar ships.

So I suspect that there is a lot of interesting technology out there in inventors' notebooks, that has not yet become commercialized, but could if the market conditions are right.

for some reason when I use Netscape 7.1 to load the page the browser claims the document contains no data, when I use IE5 it loads it all just fine, link ( I'll have to link the videos directly later, can't open both browsers at once as they tend to crash one another and the windows OS )
