From RT:
Leonid and Sergey Plekhanov, graduates of the Moscow Institute of Physics and Technology, claim they have spent years scrutinizing the Nikola Tesla's patents and diaries and they believe that with his most ambitious project - transcontinental wireless energy transmissions - Tesla came very close to unprecedented scientific discovery that could be brought to fruition.
The enthusiasts say they need about $800,000 to reconstruct the famous Wardenclyffe Tower once created by Tesla himself to implement his ideas and find a commercial application for his ideas on long-distance wireless energy transmission.
The Plekhanov brothers are raising money through IndieGogo croudfunding.

The problem from an EE perspective is he was using baling wire and bear pelts to inefficiently generate small amounts (by modern standards) of RF, but we haven't found any useful apps despite having much more efficient generation technologies.
So if the HARP in AK or your local .mil surface painting radar or local UHF TV transmitter can't economically run your cordless drill, generating RF at 1% efficiency by Fing around with Tesla coils isn't going to help the overall system work any better.
Once you get past the astrological quartz crystal worship BS level, all a Tesla coil is, is a relatively high power tuned L/C resonant circuit coupled to a high impedance (unterminated) quarter wave antenna. So you've generate a massive field using roughly "equal sized" current and voltage and the other side of the transformer has the typical antenna nodes of very high current and very high voltage at different locations. As a gross simplification. Kinda like put a fork or plastic bag twist tie or other silverware in a microwave for a demonstration of the overall effect.
TLDR is there's better ways to generate RF fields now, yet the overall economics still don't work, so going all retro isn't going to help.
GM can't make cars profitably in Detroit. I know, the solution is obviously Fred Flintstone stone wheels, that'll fix it all right up.

The main reason for GM not being able to make cars at a profitable price point, is because their resistance to change. I think Tesla (the car manufacturer, not the inventor) has shown that quite clearly.
I don't know enough about what Tesla (the inventor) intended to do, but I'm just trying to keep an open mind. I share your skepticism about efficiency in RF as we know these circuits today. But I'd also like to see some further investigation before we call it nonsense.
As an example, scientists only very recently discovered earth layers can and do produce magnetism without any significant amount of metals involved. We know that now, but we still can't explain it. According to our dogma's from months ago, it is impossible.

The square-cube law says a tesla tower will never be useful for any distance beyond what an extension cord could reach. Not tomorrow. Not with astounding new materials or breakthroughs. Never.
