Fuel oxidizer

A mechanical power producing system comprising in combination:

• a fuel oxidizer including a housing defining therein a chamber, an oxygen absorbable porous wheel rotatable within said chamber, said wheel being made of an oxygen absorbable material which alternately absorbs and releases oxygen in dependence on certain factors, a fuel inlet opening into said chamber adjacent to an end face of said wheel, an air inlet opening into said chamber adjacent to said end face of said wheel, said air inlet being spaced apart from said fuel inlet, an oxidized gas outlet opening into said chamber adjacent to an opposite end face said wheel, said oxidized gas outlet being substantially axially aligned with said fuel inlet, a residual gas outlet opening into said chamber adjacent to said opposite end face of said wheel, said residual gas outlet being substantially axially aligned with said air inlet, said wheel being operative to absorb oxygen, in a portion thereof which lies between said air inlet and said residual gas outlet opening, from air introduced into said chamber through said air inlet and allow residual gas to pass out of said chamber through said residual gas outlet, and said wheel being operable to allow fuel introduced into said chamber through said fuel inlet to be oxidized by said absorbed oxygen therewithin when said portion of said wheel is rotated to a position between said fuel inlet and said oxidized gas outlet opening and allow said oxidized fuel to pass out of said chamber through said oxidized gas outlet;
• and means which produce mechanical power by being supplied with oxidized gas from said oxidized gas outlet, said means being connected through said oxidized gas outlet to said oxidizer.
