Guest pistolpete Posted June 29, 2005 Share Posted June 29, 2005 I know that most thermocouples are used to measure temperature using the output voltage, but what about using the output voltage to do work? How much energy (%) can be had from a thermocouple? Link to comment Share on other sites More sharing options...
swansont Posted June 29, 2005 Share Posted June 29, 2005 It depends on the operating conditions, like temperature differential. This article states "up to 15%" but I think typical values are ~half of that. Link to comment Share on other sites More sharing options...
YT2095 Posted June 30, 2005 Share Posted June 30, 2005 there have been thermopile devices made that will power a small radio when you throw it on a campfire (that was the demonstration), I`ve not heard anything else about this device since the early 80`s though, so maybe it wasn`t commercialy viable?

DQW Posted July 4, 2005 Share Posted July 4, 2005 Research on thermoelectrics is still quite active. To the OP : You want to look up thermoelectricity or thermopower. Here are a few links to get you started : http://www.nanothermel.org/public_main.htm http://www.rhul.ac.uk/Physics/Nanophysics/thermopower.htm Link to comment Share on other sites More sharing options...
