One of Adam's longstanding cosplay goals is finding a way to stay cool under his costumes while wearing them all day. He's tried a variety of cool suits and hacked-togethered water-circulation units, and today he enlists the help of engineer and scientist Kipp Bradford to build a compact refrigeration system that he can wear. In fact, the system they build is a replica of the cooling unit in the spacesuit simulator used in NASA's HI-SEAS experiment!
