Yes Peter VanDerWal (thanks for the reply) I am aware of all that you said. I was planning on using at least 4 smooth wall tubes that are buried about 10 feet deep with a downward slope away from the house. The earth tubes will be about 100 feet long, and the soil here is almost pure clay (southern Louisiana in the Atchafalaya Basin).
What is the proposed diameter of your earth tubes? I wonder how much surface area you'll really get to exchange heat from.
A century ago, people used to use the air vents from mines for heating/cooling. The temperature of the air coming out of those shafts was constant year-around. A fan blew air from the mine shaft into your house. Free year-round heating and cooling!
But that was before they knew about radon and other gases. Today, I suppose you'd need to add an air/air heat exchanger so the mine air wasn't circulating in your living space.
And you'd need a conveniently located mine shaft. I'm in a silly mood today. Must be the new meds. :-) Lee Hart -- All children are born engineers. Watch them at play.
