From: mcvax.uucp!seismo!ut-sally!shell!neuro1!baylor!peter (munch)] Human muscles are quite strong enough to heat by compression. So how about this scenario: Hot moist air inside the suit is compressed, pumped through radiator fins (to dump the heat), and then let expand. The water condenses and is stored for drinking & the cooled air is pumped back into the suit. All you need to be able to do is heat a parcel of air to higher than arakkis surface temperature by compressing it. -- George D M Ross, Dept. of Computer Science, Univ. of Edinburgh Phone: +44 31-667 1081 x2730 UUCP:!ukc!cstvax!gdmr JANET: gdmr@UK.AC.ed.cstvax
