Here’s a video from someone who will show you how to get electricity just by doing some DIY, the power generated is of course free because it’s coming from absolute thin air!
I’m not really in the position to comment on the mechanism of how this actually works, neither am I great at DIY, but the video is quite interesting, because the guy in the demonstration actually generates enough voltage to charge his Nokia 3300:
If you understand this more than I do, please do offer some explanation in the comments, thanks!

This idea will be fun to work with seems to be some kind of static receiver and it does work (sort of like the right brothers first flight.)
I believe the basic idea has much potential for the future, along with some other ideas that seem to have been kept hidden from the public.
From what I can tell the actual electric comes from the antenna. Very cool!

Sorry, Tommy, but this is NOT something that ‘has been hidden from the public’, nor, to pop your balloon, is there much in the way of practical usage for this. The power generated by the voltage multiplier circuit shown (once harvested off the antenna) is generally only measurable in the microwatt range. Get on over near a commercial broadcasting antenna, however (preferably an AM, but FM’s will work, also – just not omnidirectionally), and you might get up to a few milliwatts of power. Actually tune the antenna to the particular frequency being used at that tower, get closer, yet, and you could likely harvest a few watts; emphasis on ‘few’. This idea has been around about as long as radio has, and, historically, there have been devices made that have been powered by such circuits; but… the available power diminishes as the inverse square of the distance from the radiating source; thus, my mention of getting close to a broadcast tower to see better results. In any case, about the only practical use this has been put to in the past is to power devices (very simple spy devices with quite limited rebroadcast distances, for example) that only need a few microwatts; perhaps a milliwatt, at best, under ideal circumstances. You can get a lot more power by using such a circuit near/under high-power tension lines, though, technically, the power you are then ‘leaching’ off the power lines is being done illegally; as opposed to the harvesting of radio waves that are being intentionally, freely radiated. The power company wouldn’t likely really care, though, unless you were to build a rather large, involved rig capable of extracting measurable power of more than a few watts.
