I thought that used water. I was thinking about putting a turbine at the bottom of a very deep hole and just using the heat from the Earth to turn the turbine.

Generally, when I think of geothermal I think of running pvc under the ground about 10 feet deep with water and antifreeze through it and circulating through a heat pump.

I know Iceland generates a tremendous amount of their energy with geothermal but they is obviously done on a large industrial scale.

I was thinking of something of a smaller scale for independent home use, the same way people put wind turbines and small hydro projects in their yards.
