ABSTRACT:
A system for producing and separating hydrogen and oxygen from water in which water is pumped through a preferentially permeable walled vessel heated to a high temperature by a solar energy concentrator. The water dissociates at high temperatures. Lower molecular weight components, especially hydrogen, diffuse preferentially through the vessel walls and are drawn off and separated. Oxygen may be separated from the products which do not diffuse through the walls by conventional separation techniques. A system is provided for making use of solar energy to produce storable fuels for use during periods of no sunshine.
