Ya make the opening constricted so as the air expands, it cools.
Cool part, the hotter and sunnier it gets, the more it works. Tools required. Hole saw, ABS, abs glue and a shovel.
AC powered by the sun. Easy, peaseey and free. (I love free, snork)
Could you PM me a basic schematic of that Idea? I would love to put that into action in a couple rooms in my trailer. I am a big "green" fool and if it's free it's a great price. I am currently trying to get off the grid with a wood gasifier hooked to a 4 cylinder generator for my house power. So far it supplies about 85% of my power when it is working right.
