Hi Bill, Sorry it took a few days to get back to you. I have been thinking about your double piston idea. It's not clear to me what adavantage this would have...
Hi Rick The dual piston concept was a thought of reducing heat or cold phase transfer irregularities, thus increasing engine efficiency’s. The cross...
When creating an engine to perform a particular task, a good place to start is to determine the work per cycle to be performed and how rapidly this cycle can...
Thank You Tom Some how your write up point right at my project. Thank you! Even though I'm an Engineer I'm feel as though I'm a student. That's ok, because...
Hello Tom, Hello Listers, I am in the planning stages of a Stirling engine design that I hope you all will find interesting. Most of you understand the...
I am interested. I think I am located fairly close to you, but unfortunately all I have by way of manufacturing is a MIG welder and a plasma cutter. I have...
Rick and List: I think you just made my day better....... You have my full support and encouragement. I may try to talk you out of a Ross yoke design as I...
have I ever mentioned methane as a possible working fluid?.... maybe 5 bar methane in a hot end at about 600F welded, but not exotic metals. did I mention...

Hi guys, Thanks for coming aboard. I have been concidering helium, methane, and air for the working fluid. If you can seal it safley they all are cheap! Not...
Rick, As you know from previous conversations, the GCS is based on Organ's energetic similarity principles which holds a group of thermodynamic ratios (all of...
Tom and all, Be very careful about using aluminum at high temperatures especially as pressure vessels! That could be dangerous. The strength drops of with ...

Don et al: You are quite correct. Aluminum should not be used as a pressure vessel at elevated temperatures. That is why I specifically mentioned STEEL SCUBA...
Tom, Thanks for the very clear explanation of the temp ratio. Since the the ratio or temp is not one of the input variables, I surmised to was "built in" but...
Tom, You are quite correct in your last statement. I think the last sentence in your original paragraph about SCUBA tanks may have been ambiguous because ...

Don, I just realized that my concept of the pressure vessel is different from yours. I had not planned on the heater being inside the vessel but external to...
Tom, You're right again. I thought you were talking about the hot cap. My cooler is aluminum and sees the internal pressure at about 100 C max. The hot cap...

Folks Having a concern for safety I though a few comments might be in order. If you understand all this, take no offense. I suspect however that some folks...

Hello list, I have uploaded two jpg images to the files section to a folder called 2004 SESUSA ENGINE. Please let me know if anyone has a better suggestion...
Rick, Did I nod off for a few dozen posts ? We were discussing possible heat exchanger configurations and how to estimate their performance and what to use to...
Tom, Please don't become allarmed. I have only shown the pictures as a visual guide. A starting place. The default values. For purposes of disscussion, I...

OK OK OK just a little too much caffeine yesterday. I'll be fine really.. The 3-D drawings are so nice I was worried that I had missed something. As for the...
Tom, I like your ideas for the rolled cooler. There is some room for a inner roll-up. It may be very tricky to do the vertical water channels. I want to...
Lets get some ideas from the group on ways to eliminate the tubes and the brazing of the joints. I don't think it is a problem for a medium temperature engine....
Hi all, I have a question on the single blow test apparatus for testing regenerators. I would like to know what is the blow period as mentioned in various...
Hi Cris, I have always liked Conrad's method for extending the hot cap surfaces. It lends itself to high production with drawn stainless. However, it would be...
