love the ingenuity, would appreciate just a touch more craftsmanship and increased safety/durability but the core concept is very creative; and i'm guessing he/she whupped me in the cost category - i just paid over $1,000 to have my oem vehicle a/c repaired, this guy probably paid a third of that and has user-replacable and multi-purpose modules (halving his future risk), probably got longer than my 6 months, has twice the btu's needed; might be able to duplicate for $250 with a little more shopping and appropriately lesser capacity; wonder if i could get this person to design me a microcar or velomobile! if you read this, i must tell you i'm in awe
