S-161:
Yeah, I actually have a good idea for a cooling system of the whole body. I got the idea from researching computer liquid cooling. The reservoir is going to go into the one shoulder mount while the pump will go in the other. The other thing is a radiator, but where to put it is a tough one. I'm still working out the details, but I was working on a sketch while I was at work today. Once I find a scanner, I'll post some more info.

Watertight won't be a problem. Getting the suit on and off, will be.
I'll work on some more sketches tonight and see if I can post them soon.
