Potato power!

OK, it's really more with a view to the developing world, but perhaps it's only a matter of time before this ultra-cool prototype becomes available in your local Orange Store. Scientists in Jerusalem have announced they've developed a simple, long-lasting battery powered by the humble potato.

Apparently, the secret is to boil the potatoes first, increasing their electrical power by a factor of 10. Obviously! I mean, you knew that, right?

Coming next: power your laptop by pouring coke into it. Guess what? I'm not kidding.
