Patent ID: 8424515

Claim:
A system, relating to human respiration in extraterrestrial environments, comprising: a) at least one expiration-breath holder adapted to hold expired breath; b) at least one expiration-breath cooler adapted to cool the expired breath; c) at least one gas-impermeable separator adapted to separate said at least one expiration-breath holder from said at least one expiration-breath cooler; d) at least one thermal conductor adapted to assist thermal conductivity between such expired breath and said at least one expiration-breath cooler; and e) wherein said at least one expiration-breath holder comprises at least one moisture capturer adapted to capture moisture from such expired breath as such expired breath is cooled by said at least one expiration-breath cooler, assisting formation of cooled, de-humidified expired breath; f) at least one moisture holder adapted to hold moisture captured by said at least one moisture capturer; g) at least one inspiration-breath holder adapted to hold portions of such expired breath desired to be included in inspiration breath; h) at least one inspiration-breath warmer adapted to warm such portions of such expired breath prior to inspiration; and i) at least one re-humidifier adapted to re-humidify such portions of such expired breath; j) wherein said at least one re-humidifier comprises at least one moisture returner adapted to return the captured moisture from said at least one moisture capture to such portions of such expired breath, assisting formation of warmed humidified such portions to include in such inspiration breath; k) at least one carbon dioxide adsorber adapted to adsorb carbon dioxide from such cooled, de-humidified expired breath; l) at least one further cooler adapted to further cool such cooled, de-humidified expired breath; m) at least one extraterrestrial body suit adapted to extraterrestrial body protection; and n) at least one suit cooler adapted to cool body-heat suit warming; o) wherein said at least one further cooler comprises liquid carbon dioxide; and p) wherein said at least one suit cooler comprises said liquid carbon dioxide.
