Abstract
A compressed gas engine is adapted for pumping ground water. The engine is powered by a low temperature heat source provided with a hydridable metal and hydrogen arranged operatively in a sealed loop to drive a piston. The piston is coupled magnetically to a pump piston for conjoined motion therewith. The engine is cooled by means of pumped water. A rack and pinion arrangement rides one of the pistons for electric generation.
