Stirling Engine Project

That would make sense for a low temp.  I am working on a total enclosure one ... using an old fire-extinguisher.

I would be using a small satelite dish to reflect off the sun's rays onto the displacer, so a high temperature is involved.. as par the ratio between bore and stroke, what is the most suitable one??

thanks in advance

OK then that would be a very high temp, I only know of one ever made with a parabolic mirror and you can find it for sale here http://gyroscope.com/d.asp?product=SOLARSTIR

As for the design, it would be nice to get my hands on it.

If you do make a successful project then please post it here.

I have been to that websites, it is a very interersting project. Unfortunately you didn't manage to answer my question regards the ratio between the stroke and bore?? do you have any idea about that please let me know asap thanks

02/07/09 - New Stirling design solves numerous problems
This invention is about stirling engine, which is an internal combustion engined heat machine known as hot air engine and converting the heat to mechanical motion. Invention in question is about stirling engine, having an accordion/bellows element with opening and closing feature, that is placed between the connecting rod and gas transmission pipe and moving in an expansion gap whether folding or stretching to achieve the radial motion without using the cylinder and the piston. The Advantages of Our Invention: - Sealing problem is completely removed. - Energy loss caused by the friction of the cylinder and the piston is removed. - There is no need for oiling. - Costs are minimized. - There is no need for special materials. And this causes the invention to be economical and low-cost. - It is possible to produce based on mass production. - It creates a point that, alternative energy is being reached by the individual user. To achieve the above mentioned objects, it has an accordion/bellows element with opening and closing feature, that is placed between the connecting rod and gas transmission pipe and moving in an expansion gap whether folding or stretching. To achieve the above mentioned objects, the point is obtaining the required linear motion by the hot working gas affecting the folding and/or stretching material. - Source
