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

    Peltier junctions (thermoelectric devices) do this:

    Edit: Actually, it might be more accurate to describe a thermoelectric device as exploit the Seebeck effect, rather than the Peltier effect.

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