Tesla made superb inventions as I read his patents.
I am a chemist so apologies for this question if its my ignorance.
Tesla,s key experiment was based on the concept that the earth acts as a negative ball in effect and using high frequency power he proposed that electrical power can be transmitted thru the planet and at distance the power may be extracted.. All wireless.
Why did this invention/ discovery not work?
Ie is wireless power transmission thru the earth not viable ?

Tesla made superb inventions ...
some were fictional e.g. ... https://en.wikipedia.org/wiki/Teleforce

I specifically referred to the transmission of electrical energy wirelessly Colorado and New York funded major equipement.

Many years ago I read an article on a science magazine where it was discussed the possibility to exploit solar energy generated in satellites and sent through microwaves on an Earth' station. If I remember correctly, one of the problems was not to fry people/animals/airplanes going in between [:)]
Unfortunately I can't remember those articles, but I'm sure in the web there are some.

Tesla was extremely cool, and rather eccentric. He came in a time when people still believed in the visions of Jack London, Jules Verne, as well as the 'white mans burden'. Nobody had any clear ideas about what you could and could not do with electricity, and he was ready to explore it anyway it took him. It was the world of infinite riches, infinite resources, in where nothing ever could end. In other words, It was a different world, from the one we meet today.

It seems unclear whether Tesla's Wardenclyffe Tower (started in 1901) was originally intended for wireless communication or wireless power transmission.
By 1905, Marconi's wireless communication system was achieving significant transmission distances. With the invention of the triode valve in 1906, wireless became much more sensitive, using a power source at the receiver to amplify a weak received signal.
In contrast, wireless power transmission requires power at the transmitter to power the receiver as well. This works fairly well with resonant magnetic coupling over short distances, as Tesla showed with the Tesla coil (http://en.wikipedia.org/wiki/Tesla_coil). Magnetic coupling is used today for charging of cordless devices - but the receiver has to be closer than the diameter of the transmitter coil; beyond this, efficiency drops very quickly with distance.
However, the tower would have to use capacitive coupling, and the very low capacitance between a transmitter and receiver several kilometers apart means that the received power would be unmeasurable. At best it would only be able to power high-impedance loads like fluorescent lamps, not low-impedance loads like incandescent light globes and electric motors.
Tesla was a brilliant inventor, inventing today's electricity grid almost single-handed. But achieving the same wirelessly was beyond the technology of the time (and beyond today's technology as well).
The following article has some history on Tesla's tower, and pointers to some of Tesla's patents: http://en.wikipedia.org/wiki/Wardenclyffe_Tower

Definitely wireless power transmission
Can give his patent and detailed ref
Definitely POWER
