Abstract
Apparatus for oxygenating an enclosed space as well as removing carbon dioxide from the enclosed space.
Claims32
A photolytic apparatus for oxygenating and removing carbon dioxide from a confined volume area comprising:
- a photolytic cell having an anode compartment and a cathode compartment;
- the anode compartment comprising a photo-active surface having the ability to convert water to oxygen;
- and
- the cathode compartment having an inlet connected to both as carbon dioxide source and a carbon source, the cathode compartment having the ability to react the carbon dioxide with the carbon source to form a solid or liquid medium;
- and
- a light source for providing light photons to said photolytic cell and activating the photo-reactive surface.

A photolytic apparatus for oxygenating and removing carbon dioxide in order to maintain a proper physiological environment comprising:
- a photolytic cell having an anode compartment and a cathode compartment;
- said anode compartment having an inlet for receiving an aqueous solution, an anode conductor, a photo-reactive surface, and an outlet for transporting a dissolved oxygenated solution out of said anode compartment, wherein said photo-reactive surface has the ability, upon photo-activation, to convert water in an aqueous solution to dissolved oxygen, hydrogen ions and electrons upon light activation;
- said cathode compartment having an inlet, a cathode conductor, and an outlet, the inlet being connected to both a carbon dioxide source and a C5 pentose source, the cathode conductor being able to convert hydrogen ions, carbon dioxide, and C5 pentose to C6 pentose, and the outlet being able to remove the C6 pentose from the cell and any remaining reactants;
- and
- a light source for providing light photons to said photo-reactive surface to initiate a series of chemical reactions that results in dissolved oxygen generation in the anode compartment and C6 hexose formation in the cathode compartment.
