Well, if it had worked as per specs, the energy would not have radiated into space, but rather “stored” in the earth itself until it was used by a receptor.
With to today’s knowledge about the structure of earth’s ionosphere the project would maybe still be feasible but not practical, however Tesla didn’t have all that knowledge in his time, so it was impossible for him to know.

Inductive magnetically coupled power is interesting, and could certainly have some interesting applications. OTOH, oscillating magnetic fields also generate currents in the brain, and are actually used to do so (TMS), to change brain function. They also cause seizures. Hopefully the wireless power would be developed with much weaker magnetic fields than TMS. However, the strength of the electric field an oscillating magnetic field can generate in the brain also depends on its frequency. Bottom line — I’m not putting one of those things near my head.

As brilliant as he was, you would have thought that the concept of efficiency would occur to him. Energy was then and is now too precious to transmit it in such a way that would radiate 99.9% of it into space. I guess he was more an inventor than a physicist, and the mathematics and physics of electromagnetic transmissions had probably not been worked out, although the foundations were definitely in place well before that time, going back to Maxwell’s Equations.

Good job picking this one for the book. A worthy story.

We wonder what Leonardo DaVinci and Benjamin Franklin would have thought of these^_^

Speaking of Tesla, we need to reignite the youth of this nation to get interested in science again. We are falling behind. I like what they did out in Michigan, you bring a light bulb moment to all of us. The Redway Parent Teacher Association announced that Mobile Ed Productions of Redford, Michigan will be traveling to Redway School on Monday, Feb. 9, to present an all school assembly titled “Physics Is Fun.”

The program is based on Sir Isaac Newton and his laws of physics, as well as the inventions of Robert VandeGraff and Nikola Tesla.

First students discuss sound; what it is, how we hear, why we hear, and the difference between loud and soft sounds. Several demonstrations are used in this segment to demonstrate these principles.

Robert VandeGraff and Nikola Tesla’s inventions are explored in detail. These gentlemen pioneered experiments in static electricity and are responsible for many modern pieces of electronics we have today.

Gyros and gyroscopic stability are discussed. Large working models of gyros are introduced to the audience. We then approach gravity and another of Newton’s laws. The program ends with a segment dealing with Newton’s third law, the law of action and reaction. In this segment the audience is introduced to a pulse ram jet engine. It is explained how Newton’s third law applies to jet engines.

The program is complete with visual aids.

It would be nice if it worked !

[quote]kenfucius said: “let’s see your evidence.”[/quote]After you, of course. You made the first assertion, so you have the first burden of proof. (Your “proof” will have difficulty standing up against the records of the U.S. Patent and Trademark Office, wherein are such things as Tesla’s patents for the basics of radio. Oops — I went out of turn, by providing (reference to) proof of my contention. Sorry. Go ahead with yours, now.)

[quote]Unsupported adoration, such as yours,[/quote]“Adoration”? Poppycock! “Great respect”, now, is a valid descriptor*. And, as I said above, I’ve provided (indirect) support. So, both of your terms are in error and are therefore worse than useless.

*Of course, I do not mean unqualified respect. Tesla was a weirdo in several ways, such as his obsession with multiples of 3; his insistence on having piles of napkins (18 per meal); his desire to calculate the volume of his food before eating it; his pathologic fascination with pigeons; etc.
I do not respect these aspects; I regard them with amused (or baffled) curiosity. His proven, demonstrated technical achievements, however, deserve any thinking person’s respect.
