The only reason I bring this story to your attention is a little throw-away line near the bottom: “The group is experimenting with a device that uses cows to generate power to charge its battery.”

I’m just wondering how they’re planning to do that. If they wanted to use some kind of kinetic energy generator, they’d probably suggest using dogs. The only other bovine sources of electromechanical power are… well, let’s just say that no matter how green or how efficient a source of power they are, I wouldn’t volunteer to collect any of them. 😉
