    Serious doubts this harvests more energy than it wasted in materials

      Would the materials have much more of a footprint than geothermal installations? Because that slight 7° difference between below ground temp and above ground temps apparently justifies the labor, materials, and power to the circulators for harvesting geothermal energy. So this seems to be the same but adding a cherry on top – incorporating a heat pump to add to the energy of a geothermal system.

        Would be a matter of scale. Geothermal has essentially infinite thermal mass, whereas this has a very limited amount of heat produced by bodies.
