Explain or Debunk: An onion + Gatorade = power source for your iPod

I remember the potato-powered-lightbulb gag from chemistry class, but my jaw kind of dropped when I saw the last few moments of this how-to video.

Yup, that appears to be an iPod charging its battery from a USB plugged into a f#cking onion.

They may be fine showmen, but the Household Hackers don't reveal why the bleep it actually happens. Scores of comments attempt to explain it or dismiss it as a hoax. But none of them hit that sweet mix of authority, brevity, and insouciance we at 60SS strive for.

You, dear readers, are surely smarter and more talented. Can you explain or debunk the onion-gatorade battery in 100 words or less?

Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Gatorade as the electrolyte is a proven method for this process.

You could also make a battery (or a bong) out of your head, you know.
