Nothing 'free' here. You made a receiver. I used this 30 years ago to power up a small bulb, nothing more. The energy is coming from the radio stations around so, theoretically, with a very long antenna and decent earth plug, may squeeze out about 1or2 watt .
Unfortunately you should cry. The level of idiocy is higher every day, and growing.People that have no basic knowledge claim ''over unity'' ,''perpetuum movement'' or ''free energy''. Less and less people try to read a book. We are going down, and fast.
