Excellent method for heating your water off the grid. This method is not only very efficient as it uses what would otherwise be waste heat being directed out through the stack, but it also works in much the same way as a hot water on demand system or a solar water heating system. This concept can even be directly incorporated into your current solar water heating system or as a separate stand-alone in the kitchen or workshop. Keep your mind open and remember to improvise!

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.
