Pure oxygen is used in a "rebreather" apparatus, which recycles exhaled air by topping up the oxygen level. However the only way to store liquid oxygen is cryogenically, and I don't believe today's technology is quite up to making LOx tanks the size of the ones shown. Like perpetual motion, either a joke, a scam, or an ambition born of hopeless ignorance.
