Energy Conversion

  1. Mar 19, 2005 #1
    Hi,

    Is it possible to convert heat energy into electrical energy. (Excluding boiler engines, ect...) Following along the lines of capacitance and capitors...

    Thanks.

    Peltier junctions (thermoelectric devices) do this:

    Edit: Actually, it might be more accurate to describe a thermoelectric device as exploit the http://www.autobahn.mb.ca/~het/energy/pv_fqa.html#Section02D [Broken], rather than the Peltier effect.

    What about photovoltaic cells?

    Are there PV cells that work in Infrared wavelengths?

    Yes. See: http://www.autobahn.mb.ca/~het/energy/pv_fqa.html#Section02O [Broken]?

    Also, I will mention paramagnetic refridgeration, a technique used to cool things towards absolute zero by letting heat flip little magnetic dipoles.
