they say you should believe six imnpossible things before breakfast, so here goes. here in So Cal we are in the middle of a drought and campfires are a no-no....
I believe it was Douglas Adams who said " If you've all ready done six impossible things today why not have breakfast at Milliways the restaurant at the end of...
Cris, I too have ponderd the idea of an inflatable. The problem is there is no way to make the walls of the cylinder and displacer rigid when the pressure...
List, Not all the progress on the 2004 engine design has been on paper. I have recently designed and built a simple tube bending jig to bend the stainless...
Hi Rick If you having slight problems with the tight radius while forming your tubing ( oval distortion ) Try taking a scrap length of tubing and packing it...
Hello list, I'm new to the group, and haven't quite read through the five years of postings yet, so sorry if this material has been covered before. I will get...
Hello maniacal_engineer, yes, it is hard to think of an inflatable body, that will keep its volume constant while pressure inside changes. You would have to...
Hello Mark, What you describe falls into the LTD (Low Temp Diff.) family. One of the great advantages of the Stirling (Carrnot Cycle) is the ability to tailor...
Perhaps you can get more information on an LTD by also joining the HotAirEngineSociety list. Their span of air engines includes all kinds of hot air...
So what would be the approximate characteristics of a cylindrical stack of spheres 1 inch in diameter, 2 inches long and using #9 steel shot (.1 inch in...
Although it was not a planned rhetorical question it seems to have turned out that way. So let's look at how we might figure some of this out for ourselves. ...
Rick, Your proposed experimentation with a packed bed regenerator may be the fastest way to evaluate its practicality. I approach things mathematically, but I ...
Tom, Rick et al; I was thinking, perhaps the most useful test apparatus would be a Stirling engine with the 90 degree crank replaced by 180 degree crank. This...
Tom, A wise engineer once said "One test is worth a thousand expert opinions" I seem to recall seeing a test rig as you describe in the"Air Engines" book....
I will at least be very interested in your engine and like to see more of it. I am working on an electricity producing stirling to power my home and am...
List, I had been working on a 3D model of the 2004 engine and it has become ovious that the 800 cc swept volume is too much for paracticality using a 4 inch...

Hi everybody, Glad to see that the SESUSA 2004 design/build project is coming along nicely. Hope the following provides some help : The heat transfer and...
Hi all, I was cleaning out today, and found some pieces of a catalytic converter. This appears to be a ceramic base, but what was interesting was the many...
Why spheres? I would have chosen short cylinders, say, L/D of 3 to 5. A sintered body will probably work better in many cases On choice of material, specific...
Ernie, Interesting idea. The random stacking of short cylinders would create turbulence at higher speeds but I don't think that will be the case in our...
Tom et al, In my opinion tubes are just too large a hassle. They are expensive in small bores and they are not all that easy to weld by the hundreds at both...
Ernie, Re your statement, “I believe the heat transfer rate in the regenerator is limited by conduction within the particles, (which in turn is limited by...
Rick, group first, thumbs up! neat project. and then: In TubeHX_Assy1.jpg item 8 is called piston seal, because it is on the displacer I assume the seal is...
Okay, I'm thinking Could there be a stock aluminum extrusion around that would fill the need? Ernie Rogers In a message dated 9/13/2004 6:23:08 AM Mountain...
Yes, I agree with all that you've said, except your doubts. Further, I question if the bed has to be a metal. Other materials may provide more heat capacity....
CHV, Thanks for your comments, all are appreciated. Let me try to clarify what I was thinking when I created this model. First let me say that this is far from...
I don't start the debate over again reading the content off a site mentioned on HAES, I think I got some different anwers than those resulted in the "More...
