Geothermal thermoelectricity?

  1. Apr 20, 2012 #1
    Earth ground believed to be good electrical yet poor thermal conductor.
    Is it possible to use in some thermoelectric cycle?
    For example we could make some large heat resistant artificial objects to swim in
    magma underground and establish some electric resonance between them and
    some devices on Earth surface?Could energy be transfered between hot and cold body
    with help of AC current?I dont know but there is some telluric current registered in the
    ground.The is some thermoelectric currents believed to be in Earth too.
