Abstract
Abstract A method of electrolysis is described in which the electrolysis is powered by electricity generated from the energy released by the reaction between at least one of the elements liberated by the electrolysis and a reactive body. A preferred aspect of the invention provides an aqueous electrolytic vat in which the hydrogen liberated at the cathode is reacted with liquid sodium giving sodium hydride and the oxygen liberated at the anode is reacted with barium oxide, either as a liquid or a fluidized solid, to give barium peroxide.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
A method for the electolysis of water in which the electrolyte is an aqueous solution of an acid, base or salt, wherein hydrogen resulting from electrolytic decomposition is combined with a current of sodium to form sodium hydride and the oxygen resulting from the electrolytic decomposition is combined with an alkaline earth metal oxide to form an alkaline earth metal peroxide, or hyperoxide, and wherein the heat released by these combinations is converted into electric energy which is used for supplying part of the low voltage electric energy necessary for the electrolysis.
Claim 2
Independent Claim
92 words
A method for the electolysis of water in which the electrolyte is an aqueous solution of an acid, base or salt, wherein hydrogen resulting from electrolytic decomposition is combined with a current of sodium to form sodium hydride and the oxygen resulting from the electrolytic decomposition is combined with an alkaline earth metal oxide to form an alkaline earth metal peroxide, or hyperoxide, and wherein the heat released by these combinations is converted into electric energy which is used for supplying part of the low voltage electric energy necessary for the electrolysis.
Claim 3
Dependent Claim
16 words
A method as claimed in claim 1 wherein the alkaline earth metal oxide is barium oxide.
