The Amazing Seebeck Generator

The Amazing Seebeck Generator
Andrew Lewis | Make Vol. 15- 2008 | Pdf | 9 pgs | 3 mb
With no moving parts, this simple energy-recycling
generator scavenges waste heat from a candle and turns
it into usable electricity.

Peltier cells are flat devices that draw heat from one side
to the other through a thermoelectric principle called the
Peltier effect. The cells are commonly used to pump heat
away from CPUs or graphics cards, and are also found
in camping coolers and heaters. The Amazing Seebeck
Generator uses one of these devices in reverse, to turn a
heat differential into electricity, rather than using electricity to produce a heat differential.
