Betty asks…Want to heat and cool your home for free (Very Green)?How about geothermal, for every 100ft you get an average increase of 5 degrees.
Read about the Comstock mine, at 3000 ft down you have a temp of 200+ degrees. A hell of a place to work but if you’re looking for geothermal heat it’s a great example. Now the temps will vary based upon geography but if you go down far enough you’ll get plenty of heat.
Just drop in a coil on the end of two pipes, fill it full of some
