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.
What a great idea to hold fans!! Please be aware that these "cheap plastic fans" have caused fires in barns. (Barn owners, check with your insurance company, I was notified many years ago that they would not pay if these fans were found inside the barn) The motor gets so hot that it melts the plastic, and the hot motor falls into the stall bedding or barn. Also notice the electric cord running into the next stall.. Please be aware of fire safety.
