If you don’t already have a solar powered or wind powered clock, then you might fancy this rather odd lemon powered clock. The clock exploits the lemon’s citric acid as well as the copper and zinc on the clock to generate enough current to power the clock for a week.

However, a waste of lemons I think. Just think how annoying it’ll be to re-set the time whenever you replace the lemons?
