I have an idea for a personal cooler... do you think it will work?
I'm thinking of placing one or two peltier cooler units on the side of a large aluminum container, which is filled with water. the peltier units also have heatsinks with fans on them. the fans blow the cold air on the user, while the heat is transferred into the aluminum and thus into the water. the aluminum box would be insulated to keep it from heating up the surrounding air, and the heated water could be dumped and refilled to dispose of the heat. this would allow for a sort of personal cooler without expelling hot air out the other side.
