  • after its inventor Robert Stirling in the year 1817.

    Stirling engines belong to the group of closed-loop hot-gas machines that work on the basic principal that a gas will change its volume when subjected to a heat change producing an isothermal compression of the cold and isothermal expansion of the hot gas at a constant volume. This temperature change, and thus the continuous operation of the engine, is produced by moving the gas between two different chambers producing a constantly high and a constantly low temperature.

      Hello, do you have any reference books for this article? I badly need it for my study. Thank you

      I’m glad i found my self in this kind of site because I’ll need u guys assistance on my undergraduate project. Though i got a topic on solar energy “universal solar cooker”. The solar aspect is a bit clear but I’m having a challenge on how to store the energy without cooking inside the sun and also how to incorporate the usage of electricity as an alternative power source as the topic implies. Thank you very much I’ll be expecting a response from everyone……………

      I still have not been able to find a solar energy installer who uses Stirling engine technology/ Maybe it is not as developed over time as the PV panels but it seems to me the cost would be much less to install and the resulting profits to generators of electricity would be much bigger. So you know of any installer who uses the Stirling engine/parabolic collector method?

        Stirling Engine designs have been around for many hundreds of years and as such is a well established technology. Using a parabolic dish to focus the suns rays onto a central receiver to produce more power out of a given amount of insolation is a simple idea, but the temperatures involved can be in the thousands of degrees and the resulting glare from the parabola for the neighbours makes them more suited to larger solar water-heating installations. However, there are manufacturers who produce smaller systems constructed from lightweight, polished, and aluminiumised plastic parabolic reflectors and troughs that track the sun to produce hot water or focus it onto PV panels to produce electricity.
