I am building a house and decided to build a 20' by 40' inground pool
to go with it. One of the conditions of having the pool was we would
have to extend the swimming season by heating the water. Then I found
out about inflatable domes that use the heated pool water to heat the
air and inflate the dome. Sounds like a good possibility. Then I got to
thinking that I could build a double layer tunnel type greenhouse over
the pool and use 2 layers of plastic inflated with a blower. The
plastic could be removed for summer use. Has anyone ever heard of a
setup like this? Any thoughts? Am I just loony ?
