Thermoelectric Fan Powered by a Candle Better writeup than many. Looks good due to heatsink used. A Thermoelectric generator powered by a tealight. It started as an experiment of how much power I could get from one candle. But I liked the idea and it worked really well so I built this electric-mechanical ornament. I did not use a high temperature TEG-module, but instead a cheap TEC-module. That can still handle 200 degrees Celsius which is good enough.
Powered by body heat, Lumen flashlight never needs batteries 10/16/15 The Lumen flashlight uses a thermoelectric generator to transform body heat into electricity to power an LED
Another Peltier woodstove fan. Instructables. OKish. So I bought an EcoFan for a friend and decided that it was a cool concept and built one from scratch. The fan gets its power from a peltier element that is used in reverse, i.e. it is generating electricity from the heat given off from the stove top.

Heat up your soup and recharge your smartphone, in one go. The 2-pound BioLite CampStove cleanly burns wood — sticks, twigs, whatever — and uses the waste heat from the fire to create electricity via a thermoelectric generator. It can power up most USB-chargeable devices.
