Abstract
A liquid piston Stirling engine electrical generator, the generator being a linearly reciprocating electrical generator that is powered by a Stirling engine having a liquid piston that is displaced by the cyclic contraction and expansion of a gas resulting from increases and decreases in temperature. The liquid piston and dynamic components of the linear generator are retained within a U-shaped tube or chamber, the tube being oriented in use to consist of a two upwardly extending, first and second vertical segments joining a horizontal segment. A liquid, such as oil or hydraulic fluid, is present in sufficient quantity to fill the horizontal segment and extend upward into the vertical segments.
