The reason for posting the question is that I DID go to that site first. Sure is a lot of trouble and expense to make your own aerogel, though. I haven't got that kind of time to spare, and I don't have a chemical hood with the required safety precautions. I'll end up poisoning myself to death. I tr...

Early on....I had to set my settings to automatically log me in everytime I visit in order to keep my posts from timing out. I never got the "too few characters" response, but it helped dramatically.
I eagerly await details of this engine design you speak of.

Just make sure you don't try building a baby Deltic engine. You'll go crazy with 6 sets of 3 cylinders with 2 pistons per cylinder, no cylinder heads and 3 crankshafts (2 CW rotation, 1 CCW rotation)

Yep, these are teflon/PTFE seals. I found nitrile seals in my english size at another site. http://www.sealsales.com/packing/vpacking10.shtml I would rather find them in teflon, but the nitrile can seal against thousands of psi. use 3 to seal from 0 to 500 psi. Just stack more if you have a sealing ...

The crankcase must have a thrust surface to seal against these, ...

Found this neat article. I think this might be the V4X engine. http://blog.hemmings.com/index.php/2010 ... dge-d-150/

43 KW is as close as it gets. See this link. http://www.stirlingbiopower.com/STIRLING/BASSE.swf
Good luck on finding a retail price instantly. Most places do not publish an upfront price on their very big stirling engines.
I am guessing the price is around $52,374.

Here's a very large stirling engine. http://youtu.be/duuk_r--lqU I copied the information from this site's 1st page. http://www.solarheatengines.com/ It uses the phillips rolling sock seal on the power piston. With a short stroke, of course. It appears to be a beta engine, I think. I posted the mome...

An interesting concept, but I am not so sure it is original. I may have seen it before in a paper years ago. In their design, they didn't pay attention to dead space and displacement in the engine, and it performed poorly as a result. But the concept and math was right. Just not the application of t...

A degree wheel can be printed up as polar graph paper from this site. It also has tons of other styles of graph, dot, polar, notetaking types of graph paper you can download. It has been very useful to me. I am posting this in the links area, too. http://incompetech.com/graphpaper/ Now, you can tran...

Oh, I forgot.....a digital fish scale would work if you need a strain gage unit. They have a better spread in terms of weight, and are cheap. The cheapest ones have a lower than 10lb (4.5 kg).

Building a prony brake, Ian? The best place for digital scales for me was the local grocery store or cooking supply shop. Chefmate is what brand mine is. It goes to 2kg, and has tare weight button and a timer. I use it for everything, including cooking and mead making.

I finally found an article on how to make a dynamic balancer for crankshafts, driveshafts, shaft-shafts, etc. The link is here. http://www.antiqueautoranch.com/montana500/septnewsletter/page4.html I am applying my automotive knowledge here, so bear with me. This procedure was explained to me as a k...

Perhaps I could use a copper coated stainless spring for the hot side, assuming it is possible to coat stainless with copper. Nah, probably would flake off in the high temps. I was mostly trying to get more heat to transfer to the working fluid via the springs. I normally would try to use metallic f...
