TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Apparatus: The collecting chamber includes an exhaust valve for exhausting products of oxidation of the fuel. The exhaust valve is capable of closing when the pressure and temperature within the tank-like structure reach desired operating levels. The pressure chamber includes water circulating heat exchanger device. A water circulating pump is connected with the heat exchanging device and with the water supply mechanism. A temperature responsive control mechanism is provided for the water circulating pump. The pump mechanism includes variable output gas operated pumps driven by carbon dioxide gas from the carbon dioxide holding tank and steam from the heat exchanging devices. The heat exchanging mechanism includes an upstream heat exchanger, steam generating unit, and coolant water pump connected with and between the water supply mechanism and the upstream heat exchanger unit. It also includes a downstream heat exchanger unit through which carbon dioxide coolant cools the hydrogen and carbon dioxide gases thus converting carbon dioxide into liquid state and separates from the hydrogen gas. The oxidizer supply mechanism includes an oxidizer supply tank in which the oxidizer hydrogen peroxide is stored.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The sulfur absorber includes a porous gas conducting bed of metal oxide aerogel microspheres containing elements consisting of cerium, zinc, strontium, magnesium, copper, lanthanum, barium, iron, yttrium, chromium, cobalt, vanadium, zirconium, or precious metals. The steam reformer mechanism comprises a porous gel consisting of metal aerogel microspheres containing nickel, copper, zinc, iron, cobalt, zirconium, chromium, rare earth, or precious metals. The carbon monoxide scavenger mechanism includes a porous gas conducting bed of aerogel microsphere of mixed metal oxides Mn oxides On consisting of nickel, manganese, tin, copper, silver, iron, zinc, and/or chromium.
