You didn't anser the post, dufus. Here it is again:<quoted text>
You claim to be a geologist.
What a joke.
This is not geothermal HVAC as considered in the marketplace.
Like you really understand what you posted.
I'll put it to you simply:
Geothermal heating is a piece of cake. Just drill a hole to the temperature you desire, and circulate water through it and throughout the building.
Geothermal cooling is very difficult. Why? Because the heat you transfer from a building to the ground has to be transported away from the location of the building, or it just rises back into the building.
How about this one:
How is the heat transported away from the location of the building after it has been transferred from the building to the Earth immediately below the building?
... your turn, dufus.
