How about this? A coffee machine that brews coffee without using electricity? Gun Ho Lee came up with a better way to save electricity with this Solar Coffee Maker. As its name implies, it completely uses the energy of the sun to recharge its battery.

When you come to think of it, lots of energy can be saved around the world if all coffee makers were solar powered. As it is, I just refilled my 2nd cup of the day.
