6. Prof. Senft at the University of Wisconsin - River Falls . This gentleman is one of the active researchers in the Stirling Engine arena with particular emphasis on low-temperature-differentials. It has some nice pictures of the Ringbom LTD engine the author built at the Argonne Laboratory. Along with that goes an impressive list of publications under the name of "Senft J.R." ( James ). Email address : j.r.senft@uwrf.edu He is in the department of Mathematics.
   
   
7. Homepage of Prof. Israel Urieli at Ohio University, Athens. Of particular interest is his Stirling Engine page containing a potpuree of links and pages , mainly to form background information for his course ME 422 Stirling Cycle Machine Analysis.
   
   
8. (pdf) Summary of Nasa's Stirling Radioisotope Generator ( April 2002 ). Free-piston 55 W Stirling engine with plutonium as heat source and a linear alternator to generate about 55 W of electricity. This is a sub-project of NASA's project Prometheus
   Stirling Engine Projects by NASA Glenn Research Center. This site has some very nice information about various Striling Engine Projects. One major focus is the 55-W Stirling Radioisotope generator which is built/tested in conjunction with the Stirling Technology Company (STC) of Kennewick, WA. (llok for link "Dual RG-55 Space Power").
   Among many links on the NASA site you find an entry point into two Stirling machine codes called GLIMPS and HFAST design codes.
   

   "Predictions from GLIMPS and HFAST design codes are compared with
    experimental data for the RE-1000 and SPRE free-piston Stirling
    engines. Engine performance and available power loss predictions are
    compared. Differences exist between GLIMPS and HFAST loss
    predictions. Both codes require engine-specific calibration to bring
    predictions and experimental data into agreement."

   
   
   
9. Automotive Stirling Engine Development Project at NASA Glenn Research Center>.

   "More than 21,000 hr. of testing were accomplished, including
    4800 hr. with vehicles that were driven more than 59,000 miles.
    Mod II engine dynamometer tests demonstrated that the engine
    system configuration had accomplished its performance goals
    for power (60 kW) and efficiency (38.5%) to within a few
    percent. Tests with the Mod II engine installed in a delivery van
    demonstrated combined metro-highway fuel economy
    improvements consistent with engine performance goals and
    the potential for low emission levels. A modified version of the
    Mod II has been identified as a manufacturable design for an ASE.

Commercial and Hobbiest's Sites

1. Links, links, ..links to other pages, assembled by Orrin B. Iseminger.
   
   
2. A commercial 1 kWe Stirling Engine by "energy.ch - Das schweizerische Portal zur Energie" . Strictly in German, well written with some nice thoughts, but few details beyond : Free-oscillating engine with displacer and power piston. 50° phase lag. He at 35 bars , Pressure amplitude 5 bar. heater temperature 550°C. Ratio of electirc energy to heat input = 0.2.
   
   
3. Epas A company in Germany which produces 2 (or 3 by now) different types of Stirling Engines ( 400 W , 1000W and ? ). I am somewhat cautious about this company. Prices have not been entered since Germany moved to the Euro.
   
   
4. SNAP A design tool by Alan Altman, needs Excel. Although somewhat costly this numerical analysis tool incorporates quite a bit of science. It also has a neat little basic theory page about heat exchanger.
   
   
5. Jerry E. Howell's Model Plans and Kits This is a very nice place for small model stirling engines. Plans and/or kits (or essential parts kits ) are available for modest fee. Among others the Miser Engine which is a low-temperature-differential engine.
   
   
6. HowStuffWorks This is a neat little site about Stirling engines written for the somewhat serious beginner. by Marshall Brain's "HowStuffWorks" series.
   
   
7. The Idaho Stirling Engine Homepage by Chris Daniel & Eric Johnson representing the results of their design/built project at the University of Idaho. Neat to see their low-tech approach to a displacer-type stirling engine. No hard information though and could not find links to supervising professor. (Dr. Elger, ME 430 , Senior Lab).
   
   
8. American Stirling Company. A commercial company, selling our kind of plans and kits to built Stirling-type like engines. Good for the hobbiest.
   
   
9. LTD Stirling Engine An article with construction details of an LTD stirling engine very similar to the Ringbom engine. All from Australia. Seem to have a complete set of drawings in construction hints.
   
   
10. Study Group Stirling Engine The whole project was initiated by Mr. Viebach, who developed an engine with a shaft power of 500 Watt. He developed and produces a casting which makes it possible to build this gamma-engine.
    
    
11. Let's build model stirling engines If you have some machine tools and know how to use them, you can easily build model Stirling engines. Here are links to other pages with plans for easily constructed Stirling engines and the instructions for their assembly. by Prof . Koichi Hirata for the layperson
    
    
12. Whispertech in NZ The revolutionary WhisperGen Personal Power Station is a micro combined \ heat and power system based on a Stirling external combustion engine. It is the result of 8 years of design and development work by Whisper Tech Limited.
    
    
13. Solo Stirling Engine Co. SOLO has been concentrating on Stirling technology since 1990. Initially, three 9 kW engines were designed and manufactured in solar version for the test station "Distal" by Schlaich, Bergermann and Partner (SBP), Civil Engineers in Stuttgart. The test site is located at Plataforma Solar in Almeria / Spain. SOLO acquired the license from SBP for the most advanced Stirling engine SPS V160 with regard to life expectancy and reliability.
