A video produced, by Household Hacker, that depicts an iPod being charged by a Gatorade powered onion has been circulating the internet recently, making Gizmodo, Digg, The Gadgets Weblog and TUAW. The video looked pretty neat and I had to test it out for myself. I was pretty skeptical, as electrolytes in solution just conduct electricity, they won't produce it and the anode and cathode would have to be two different metals. I hoped that the onion would add something to the mix so that it would work. I followed their instructions exactly, but sadly could not get either my nano or 4G iPod to charge.
I am pretty sure that there are two different cords in the Household Hacker video. One is coming from the onion and the other from a power source, through that suspicious notebook that the iPod is sitting on.
