ydoaPs Posted April 10, 2010 Share Posted April 10, 2010 How much power could I extract from body heat using a TEC? I don't need much(just powering some LEDs). Link to comment Share on other sites More sharing options...
darkenlighten Posted April 11, 2010 Share Posted April 11, 2010 What is a TEC? Depending on how that works, I might be able to assist. Link to comment Share on other sites More sharing options...
ydoaPs Posted April 11, 2010 Author Share Posted April 11, 2010 It's basically an arrangement of thermocouples. They use a difference in temperature to generate a voltage. Link to comment Share on other sites More sharing options...
Moontanman Posted April 11, 2010 Share Posted April 11, 2010 I think the human body puts out about 100 watts in heat energy YodaP. Link to comment Share on other sites More sharing options...
darkenlighten Posted April 11, 2010 Share Posted April 11, 2010 Probably not that much then, do you know how many volts per degrees the TEC can produce? It doesn't seem like you would be able to produce enough from using body heat, due to heat transfer from you to the metal. You most likely would not be relying on just what the body can generate directly, so the way the device works will greatly effect what you can get. Just because you convert your temperature into energy via KT or of the like, it is somewhat arbitrary until it is applied to something. Link to comment Share on other sites More sharing options...
