A firsters dream come true air-condition. I finaly cracked it all made of cheap materials 4 platers coolers in series parallel and 2 pumps also in series and 2 7.5 volt battery's NiCad's hi ampere for long use. This project took a while untill I had all the parts plus I'm building a plush fox suit and this will be needed badly. What you see is themain cooing pack laminated in 4 peace's of aluminum copper tubing flatten for the heat conducer 4 palters 2 caps 2 pumps and a hole lot of tubbing the outer coil and the inner coil laminated in foam the outer disapates the heat threw the fur as the inner keeps you cool as a cucumber ,this took a week for the build. If any one is asking on wear the heat is dumped is threw the outer layers the fur so any one that want's a hug the body will be very warm.
