Come across this searching for earth tubes. My son just bought 6 acres of raw land and would like to stay off grid if possible. The small sheds are easy, but staying cool would be a challenge in SW MO.
There is a cave that has a small amount of water output. You can crawl in and maybe get to a point where you can sit up. I was thinking if a guy could build a small shed by the cave and run some long pipes in that cave to capture all that cool air and then somehow insulate it as it comes out of the cave into the shed. Kinda just like burying the tubes in the earth but using the cave instead and no digging. Thoughts on this?
