Default Cool idea: gravity powered LED light

The wonders that are LEDs have allowed us to do some pretty cool things like make the shaker and crank flashlights. Well, a company has made another pretty cool LED light that uses gravity to power an LED lamp/light. You basically hang the lamp and then hang a weight off of it. The weight spins a generator and provides power to the lamp. To recharge the lamp, you simply lift the weight back up. Its only a few pounds, so its real easy to do. The gravity light can also be hooked up to other things to recharge them. Its pretty cheap too. Pretty cool idea IMO.
