Nikola Tesla's wireless energy
Jun. 1st, 2009 06:28 amThe only electronics kit I ever had demonstrated that you didn't need a power source for a radio reciever, which is kind of neat.
So couldn't you just radio broadcast a 60z tone, rip the headphone off that unpowered radio reciever and attach an a/c volt meter and get a reading?
I had heard that Tesla thought he had figured out how to charge the sky to give everyone free electricity, but that must have been crazy, right?
A couple days ago I watched this:

That was the first time I heard he was building a radio tower to attempt the first trans-atlantic transmission - which also happened to be his sky charging machine. So he had broadcasting access to the entire electromagnetic spectrum, and presumably lots of power.
And thismorning I lay in bed lazily contemplating how a radio transmission becomes an audible tone. Since I'm not much of an electronics geek, I first thought, hey, that makes a speeker reciprocate, and generating electricity off of that is easy - before I realized you could just use the speaker inputs as power outputs.
Anybody have a radio transmitter, perhaps one of the tiny ones for getting a cd player to talk to a car stereo? Those unamplified radio kits must be cheap.
What am I missing here? How is wireless power not obvious?
I remember reading recently that somebody finally recently invented wireless power - something involving ocelating electromagnetic waves - duh.
Funding for Tesla's transmitter was cut off when they found out about the broadcast electricity thing, because the people with the money wanted to keep charging for the electricity.
