In 1960, before the first man went into orbit, NASA was trying to find ways to exchange CO2 for oxygen on long planetary voyages. They found that duckweed, a common fresh-water plant belonging to the lily family, did the job. NASA managed to grow duckweed two-dimensionally on big sheets of absorbent paper, so each 'pond' could be suspended vertically and irrigated from the top. 25 square feet of duckweed, 5 x 5, is enough to exchange the atmosphere for one adult. So a 'greenhouse' the size of a file cabinet would be able to grow enough duckweed for a crew of 10.
The comparison is visually obvious: The volume of plant material is about the same as the volume of the person. Volume = volume.
This was before NASA was LBO'd by the Gaian religion-racket. Now that Gaia runs everything, we aren't allowed to know how little plant material it takes to balance one human.
Nice synchrony as always. I was thinking about astronauts yesterday, and thinking about Gaia's murderous REVERSAL of this exact fact a few days ago.Labels: Carbon Cult, defensible thymes, defensible times
