Sterling Engine

Today's post is about the Sterling Engine.

Wikipedia describes the sterling engine as "A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work."

The Sterling Engine was conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.

The Stirling Engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source. This compatibility with alternative and renewable energy sources has become increasingly significant as the price of conventional fuels rises, and also in light of concerns such as peak oil and climate change. This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.


Today with the new technologies that have developed along with space age materials the Sterling Engine is starting to have a revival.

Here is a New Sterling Engine site that explains how a Sterling Engine can be used with solar to make a very efficient solar energy system.    The Solar Energy Plant
