Sorry, no video will be added, where I live it's been snowing and it's producing terrible results. Right before it started snowing it produced a thrid of a volt in a couple of hours, now that it's snowing and that it's officially winter it's only charging up to 0.03 volts, which is terrible. If you know how to solve this problem then please comment!
THIS IS REAL, NOT A HOAX
Step 1: The Theory
The earth and it's atmosphere is basically a giant capacitor, when lightning strikes it discharges it. Tesla's device sucked power from that infinitely charging capacitor to charge a man made capacitor. By putting an electrode in the air and an electrode in the ground, you tap into these energy source to charge your own capacitor.
