Domestic breathing machine
A veritable domestic breathing machine, O generates pure oxygen in the home. In big towns, oxygen levels are 90^ lower than those required by our bodies under optimal conditions. Using an oximeter sensor, O constantly monitors the oxygen level in the air, and when it detects that this level is insufficient, it instantly activates the microorganisms it contains, Spirulina Platensis - a living organism with the highest yield in terms of oxygen production - and a light that favors spirulin photosynthesis. This emits native oxygen, which is diffused into the surroundings. As soon as the air oxygen level has returned to optimum, the light and agitation are interrupted and the spirulin falls back to the bottom of the container. At present NASA is carrying out very detailed studies on this subject , in connection with long term trips for its astronauts.
