I found this on the google [link to en.wikipedia.org (secure)] "In an independent space suit, the heat is ultimately transferred to a thin sheet of ice (formed by a separate feed water source). Due to the extremely low pressure in space, the heated ice sublimates directly to water vapor, which is then vented away from the suit. The ice sublimator consists of sintered nickel plates with microscopic pores which are sized to permit the water to freeze in the plate without damaging it. So when heat needs to be removed, the ice in the pores melts and the water passes through them to form a thin sheet which sublimates (like dry ice). When there is no heat needing to be removed, this water refreezes sealing the plate. The rate of sublimation of the ice is directly proportional to the amount of heat needing to be removed, so the system is self-regulating needing no moving parts." |

Tomorrow we will have a learning experience with them wile I smoke the last 19 BLACK 33's and then sacrifice the last one to nature. It seems they magically decided to stop making them.. Which is all for the better, and I bought the last pack. |

Quoting: Rosicrucian1 77804393 You are one of those guys that sprinkle roundup on your salad as a flavor enhancer, and tell others it taste fine, it's actually good for them. |
