Stirling Engine Technology – Converting Heat to Mechanical Work or Electricity

Stirling Engine Technology ( Solar Thermal Magazine) – A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (called the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. Simply said the engine is able to convert heat into work that can be used to generate electricity or power some other application. The Stirling engine, is the basis for parabolic, dish and tower concentrated solar thermal energy systems.

This video shows the developmental progress of a high-performance Stirling engine intended to power an electrical generator. (SV2 MKII by Kirk Engines, Inc)

The goal in this case according to the author is to have a propane-fueled, portable generator developing approximately 500 watts @ 12 volts DC to charge battery arrays.

    The stirling cycle engine pre dates the steam engine.
    I’ve got to correct you on them being used as the basis for tower concentrated thermo solar systems. Although this site reported on such a use for engine recently and may be of use in small scale generators. The large scale concentrated solar thermal systems using heliostats only uses salt as the transfer and storage medium of heat and therefore energy.

    for some reason I cant find link for video, is there any suggestion?

  • Steven says:

    The Stirling engine dates back to the 1800’s. There are websites devoted to building them out of scrap you might have around the house. How is this news?

    I m interested to construct a Stirling engine for my home purpose. I m already familiar to compressed air engine with my own design while in school. So can I have some strong idea on stirling engine cylinder n piston mechanism.

    This U-Tube video has been inactive – no further posts from the original Author – LAST YEAR when you 1st posted it !

    Not your finest hour in getting the story out there !
