Stirling and Hot Air Engines Keith Strong, Roy Darlington

[Edited for clarity, also changed Name]. These engines work by exploiting the way gases expand in hot temperatures and contract in cold temperatures. It is a Lamina Flow type hot air en. I am tired of patching air leaks in wooden boxes and of complex mechanical linkages. In it sits a radiator which receives a closed loop of coolant liquid (water). The images below show some of The Stirling engine (or Stirling's air engine as it was known at the time) was invented and patented by Robert Stirling in 1816. The liquid is sent to the heat or cooling source, and then back to the radiator. What I want to do is to build a simple experimental engine from which I can collect Instead of using a displacer to move air between hot and cold chambers, use a fan to move air though a stationary regenerator. "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. The hot air engine (aka: “Stirling engine”) has been around for a very long time. Starting October 2012: An unsuccessful attempt to make a beta type Stirling Engine to pump spa water and solar array fluid. The Stirling engine is composed of a sealed cylinder filled with a working gas. It can run off of just about any heat source, even the Sun! The cylinder is filled with air. The project aims to the realization of a system for the cogeneration of 1 – 3 kW of electrical power and 8 to 24 kW of thermal power (for heating or hot sanitary water generation) by integrating the engine in a pellet boiler, achieving an overall efficiency of about 0,85 – 0,9. A Whispergen is powered by a Stirling engine but thats the choice of whisper technollogies for its quiet opperation! Interest in the technology has been revived in recent years by those exploring new methods for producing “Green Energy”. "A Stirling engine is a heat engine that operates 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.
