THE SCIENCE:

Air purifying method for PO₂R and energy source

An intake and exhaust fan channel air containing pollutants such as CO₂ into the lithium peroxide canisters inside the PO₂R bracelet and expel oxygen for the consumer to breathe. Lithium peroxide (2LiOH) is stored inside these canisters in a powdered state. When exposed to CO­₂, a chemical reaction occurs with 2LiOH that releases oxygen and lithium carbonate as a by-product. The released oxygen is channeled out via an exhaust fan for breathing. Once the lithium canister is used up, it must be replaced.

Water-activated batteries are the main source of power to operate the intake and exhaust fan. The batteries consist of a powdered carbon capacitor. When moistened by water, it creates a current that provides the same energy output as an alkaline battery with 1/10^th the cost and considerably minimalized waste.
