Title: Message

I do not remember his name. At the time I had a small lake property and looked at it for a cheap method to cool. I was going to do it myself, as his price was many thousands of dollars. I could have rented a backhoe for a day at $175 and it would have taken maybe two days to dig. I sold the property as the taxes went up 300% when the oil revenues of the county ceased supporting the tax base. So I never did try it but I still think as a passive cooling or heating method it sounds great and requires very little energy.

 

Was that Mr.. Duggan out of Albany NY?

 

 was told that in most parts of the U.S. there is 'theoretically' enough btu's coming in over the year to keep a Greenhouse at 65F year round. Most of us are farming in a less than theoretical world though.

 

There is a fellow that used to dig a 2’ wide ditch about 15’ down then lay down 2 each 4” PVC pipe covered up about 1’ then put 2 more 4” PVC pipe down in a big U that went out 75 ‘ across 50’ and back 75 foot. He would then pump air down the pipes from inside the house and get the air at a constant 68 degrees in the winter and around 74 in the summer. I don’t know what happened to him .  I thought that it was a neat idea and wondered if that would be enough to help a greenhouse. The earth does use the whole season into the next season if you go down enough it gets fairly constant.
