Candle Powered Heater - I've been looking a various ways to make these and this guy has by far the best setup. It isn't so much a how-to video. He is just showing what he used to construct his version of the terra cotta pot candle heater.
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.
"You are the original lamp. Other incarnations may possess the same candle power as the original lamp but the original lamp is the beginning of all light." ~Lord Brahma, in "Prayers Offered by Lord Brahma to Lord Krishna" ..*
Wow... Power outage in the cold of winter? You never know when you might need a heat source. This "life hack" is brilliant and simple as long as you keep the necessary items on hand: Bricks, terra cotta pot, tealight candles, matches.
