Subject: Re: Save $$$--use geothermal systems.
Someone I have known for decades discussed thermal heat and cooling systems with me a few nights ago.

If you do not have a runoff system where the water is released into the nearest body of water, then this is very ineffective. He claimed a 40% efficiency rate with the release of the water. That is not enough for deep-freezing temperatures.

With runoff, you can get very high efficiency rates, but the runoff for better-sized projects is illegal.

Thermal systems are still subsidized by the federal government. Unlike EVs.
