i think im getting way to technical but i have made a small a/c system that i made for a project in one of automotive HVAC class...i just made a small a/c that instead of using the engine to spin the compressor, i used an electrical motor that i could plug into the wall outlet...it blew cold air in an instant...really an a/c is really simple so im thinking about making one with spare junk parts so i don tknow

i think growing in a fridge would be cool instant cooler temps!
