Citrus-Powered Clock
December 2nd, 2008
You would be crazy not to want a Citrus Powered Clock. I mean, seriously! It is powered by a lemon and it keeps time!

Unfortunately, it isn’t for sale — yet. Otherwise I’d snap one up. Designed by Florian Dussopt + Julie Girard. The wooden plank has two spikes of copper and zinc built into it. Reportedly, a single lemon will for your digital clock about one or two weeks.

Awesome! Too bad they’re not for sale. Is there ANY kind of battery or capacitor to keep the time current while you swap fruit?

I don’t know, but since there are two spots for the lemon, I think it would work while you remove one of them temporarily. I’ve heard this sort of thing works with a potato as well.
