This is simplaly awesome, how cool is it that you can make electricity from heat to power small electronics. Make one of these in case the power goes out and look cool all at the same time.

Here is the basics: 

I´m using a thermoelectic module, also called peltier element, TEC or TEG. You have one hot side and one cold. The temperature difference in the module will start producing electricity. The physical concept when you use it as a generator it’s called the Seebeck effect. Thermoelectic modules are mainly used for the opposite effect, the Peltier effect. Then you apply a electric load and it will force a heat transfer from one side to the other. Often used in smaller refrigerators and coolers.
