Abstract
The principle of the acid/soda fire extinguisher is applied to generating pressure in the expansible chamber of a power plant or engine. Pressure is generated in a first container by adding sulfuric acid to a bicarbonate of soda solution and the pressurized solution is applied alternatively to the two sides of a double acting piston. The unpressurized side of the piston is alternatively connected to a second container for the collection of used solution. When the solution in the first container is used up, the solution in the second container is activated by the addition of more sulfuric acid and the cycle is reversed.
