RECTENNA ?

Would it not be possible to build a circuit tune in to the RF/Microwave frequencys already generated by radio/cell companys to generate free dc current ?

Had a look but there is little information out there.

Anybody know much about them or tried building one ?

It's better if you use Solar Energy, but not the classical solar energy that people use, not expensive and low efficient fotovoltaic cell. The Sun is always charging the Ionosphere, the ionosphere is like a big capacitor where you can get energy from if you know how to do it.

How much? About 50 KiloWatt, a good amount. There is similar to Henry Moray Device.

I THINK THE POWER FROM THAT IS VERY LOW
THINK ABOUT HOW THE WAVES PROPAGATE
THE WAVE FRONT FROM RADIO EMISSION IS MUCH BIGGER THAN THE RECIEVING END
(SEE PICTURE)


@MAGNETHOS

I GUESS IF YOU HAD A CONDUCTOR LONG ENOUGH TO GO INTO THE IONOSPHERE THERE WOULD BE A LOT OF POTENTIAL THERE-
Hmmmmmm
I SAW A THING ABOUT HOW SOMEBODY WAS USING AN ULTRAVIOLET LASER TO RAREIFY THE AIR AND MAKE IT CONDUCTIVE FOR A LONG RANGE TASER
WONDER WHAT WOULD HAPPEN IF YOU AIMED A REALLY BIG ONE INTO THE IONOSPHERE

@Pyrodin

I don't know much about that, but most people think that they need a conductor. I think that you don't need a conductor. Henry Moray used a simple antenna to get the energy form the ionosphere, but not a very large antenna, he used this antenna


I have also heard that this antenna works good. You have to resonate at the same frequency of the ionosphere and then amplify the energy. I don't know about that, but this is the theory that I have read.
