Oh, and about the wireless power, which the video clip is about:
"Did Tesla plan to transmit power world-wide through the sky?
It was his ultimate plan, but the farthest he ever got was the partial construction of his famous tower at Wardenclyffe which was intended for wireless communication across the Atlantic. His worldwide wireless power system was theoretical only, employing the Schumann-Tesla resonance to charge the Earth's ionosphere such that a simple handheld coil could receive electrical power for free anywhere, and everywhere, in the world. Tesla's idea was innovative, but innovative idea it remained, as debts mounted and the tower was dismantled before it ever got to be used. Now that the nature of the ionosphere is much better understood, physicists now consider Tesla's concept unworkable, and no attempts to test it have ever worked.
All sorts of conspiracy theories exist, for example that the HAARP research facility in Alaska is secretly a test of Tesla's worldwide power grid, or some sort of superweapon based on it. The profound differences between these systems become clear upon doing even the most basic of research."
- sp332 13y agoI'd forgotten about the "charging the ionosphere" part, but there is a wireless (well, effectively wireless) transmission system that only requires a common ground. Even just plugging a wire into the earth works. http://events.ccc.de/congress/2009/Fahrplan/events/3696.en.html http://events.ccc.de/congress/2009/Fahrplan/events/3696.en.h... Note the video linked at the bottom includes a demo.
- officialjunk 13y agohmm... i believe that for long distances, tesla planned to use the conductivity of the earth itself, because of it's low impedance, to send AC current to any point on the plannet's surface (http://www.google.com/patents/US1119732?printsec=abstract http://www.google.com/patents/US1119732?printsec=abstract). for short distances, air transmission was possible, but there is strong drop-off in efficiency because of air being an insulator (https://www.google.com/patents/US645576?printsec=abstract https://www.google.com/patents/US645576?printsec=abstract). also, people do consider his work "workable:" http://web.mit.edu/newsoffice/2010/wireless-power-0409 http://web.mit.edu/newsoffice/2010/wireless-power-0409 the rumor is that tesla intentionally left out key details in his patents to keep from dangerous tech being in the wrong hands, while maintaining the rights to the tech. so, we aren't even able to reproduce tesla's levels of efficiency or distance without re-discovering certain aspects... but to say that physicists consider his concepts unworkable is false. edit: typo
