Stirling Forum Home Page

<t>Since Dr. Senft's N92 LTD Stirling engine is a model the Model Engine Forum would be the best place to find information, suggestions, and tips regarding Stirling models. It might be well worth your taking the time to wade through the good the bad and indifferent there.<br/> <br/> Various methods ...

Gary: Scans of three pages will help you understand the operation of the Ericsson cycle. These are pdf documents and as such can't be uploaded to the files section. Please comment if you wan't them by email.

<t>The best explanation of the Ericsson cycle engine is in a book by Robert Sier, "Hot Air, Caloric and Stirling Engines" Vol. I, A History.<br/> Published in 1987. It is hard if not impossible to find a copy.<br/> <br/> There is an account of the Side Wheeler Ship "Ericsson" circa 1851 and a schema...

<t>PTFE vs. graphite:<br/> <br/> PTFE is difficult (almost impossible) to machine to the fit in a given cylinder compared to graphite and will not withstand the higher temperatures that graphite will.<br/> <br/> The fit of the piston in the power cylinder should be such at to slide freely through th...

As far as I know there are NO plans available for use in building reproductions of Jim Symanski's Stirling engines.

The best information available is on Justin Symanski's web site at where you will find many photographs of Stirling engines made by his father Jim.

P. M. Research sells a kit or assembled reproduction of the original unit.
Individuals may have an original and/or additional information about the product(s).

<t>IF you took the time to read the subsequent posts, the one by # Catherine Chagnot, April 23, 2009 in particular you would have found the answer to your question. i.e. Too Much for the results obtained.<br/> <br/> I was not aware of the deviations from original designs until long after the book ha...

<t>"Yes but it is still only 800 watts. "Stirling engine" technology is the product of 1800 need for a reliable "Non-Explosive" engine to pump water from the coal mines. It is obsolete except for niche applications where the Stirling engine design is specific to the application. There are NO off the...

<t>Rob Myer: It appears you have a misunderstanding of Stirling engines their operation and application(s). A Stirling engine takes heat input from a high(er) temperature source, converts a portion of that heat energy to mechinical energy, the output, and rejects the balance of the heat to a low(er)...

I have no idea of the MTBF for the commercially made units but would expect them to last well beyond the l0 year break even point.

An online search for "Micro gen CHP" and similar terms as well as should answer most of your questions.
