Space technology descended from heaven to earth and straight into the car! The company "Aerospace Technologies", engaged in the development of life support systems for ships plowing the expanses of the Universe, "in its spare time" took care of the purity of air in ordinary cars.
What contains the air of busy city routes, no need to explain. Automakers are vying to offer in-car filters, including activated carbon, but … they are very cunning, offering to replace them every 15, 000 km. What thousands - the company’s specialists were convinced that activated carbon loses its absorption capacity after … 4 hours of driving around Moscow during the peak. Then it filters only dust, not harmful gases! You can, of course, turn on the recirculation mode, but here is what the person himself releases into the air: carbon monoxide and dioxide, ammonia, amino compounds, acetic acid, aldehydes, ketones, methane, dimethylamine, methyl ethyl ketone and, we are not afraid to call it, ethanol. In short, the air for 30 minutes in an isolated cabin becomes so stale that staying there without opening a window is simply risky.
So the space specialists came up with an aggregate capable of regeneration. Its coal packing every 4 hours restores its properties: the accumulated harmful substances will displace outward the vapor obtained from water collected in silica gel. And at this time (regeneration lasts about an hour), passengers breathe air from the cabin, which is cleaned by the second branch of the unit. Then the roles change and the second filter is regenerated. And so on until the end of the trip.
