Abstract :
A novel buoyancy engine for the propulsion of underwater gliders is presented. The research explores the direct volume expansion of hydrogen gas from the reaction of lithium hydride with seawater. As a result the seawater is expelled from the reaction chamber creating buoyancy and consequently also propulsion. The hydrogen produced can then be used to create electric energy in a fuel cell for use by the vehicle control system and on-board scientific payload.
