rebreather

With signature speculation and imagination, BLDGBLOG presents an interesting abstract on the implication of the peculiar properties of a cobalt-salt, which can rather horrifyingly like table-salt to slugs, suck all the oxygen out of a room. The crystal, however, is also capable of the reverse—that is timed-released of the sequestered oxygen. Learning how to harness this little trick could mean big advances it SCUBA operations—culling air from the water—and even for space exploration, as the storage medium is chemistry, rather than bulky, pressurized-containers.
