We ’ve learned that there are two problems with being in an air lock . The first , run out of oxygen , is comparatively minor . In a ten by ten pes room , you should be fine for three day . The major job is breathing out carbon dioxide , which at concentrations of about two percent – at standard atmospheric temperature and pressing – will vote out you .

The easy way of life to keep yourself alive in an air lock would be to carry it with plants . But how many plants are enough ? This is a harder problem to solve , because there are endless variable . One of the most vexing single is the fact that plants farm less oxygen as carbon dioxide levels increase . They get different amounts of O at unlike phases of their growing cps . They take in different amounts of carbon dioxide at dissimilar temperature . And finally , some flora only “ breathe , ” at night so as to save water – which if you are in a incessantly light up room or are killed after only half a day does n’t do you any secure at all .

scientist estimate a safe oxygen consumption of 50 cubic decimeter per hour for a homo . Meanwhile , a leafage gives off about five milliliters of oxygen per minute . A soul would need to be in a elbow room with about ten thousand leaf . About 300 to 500 industrial plant would produce the right amount of oxygen , but it ’s much harder to estimate the amount of carbon dioxide the plant absorb , specially if every fourth dimension a person breathes out , they inhibit oxygen output . To be safe , do n’t get into an airlock without convey about seven hundred potted plants with you .
