How to Charge Your Cellphone Using Wasted Heat
Ilya writes "Companies such as BMW are investing in Thermoelectric Generators to make their cars more efficient by replacing the alternator. Thermoelectric Generators convert wasted heat from the engine into electrical power. This green instructable shows how you can use the same technology right now at home to harvest expelled heat from home appliances to charge your cellphone and other gadgets.

I used to have neighbors who would leave their air conditioners running all day, then, when they came home, they'd let the doors hang open for a while to let some warm in. Less stupid people could help, too.
