Thanks for posting your work here. I carefully read over the pdf one time, further scanning over the info at the link, and I take it you have yourself built a quasi-operational system? Quasi meaning that it might not be pretty nor ready for prime time, but one which proves the design? Just asking is all out of personal interest. Any kind of pictures of your set-up would be useful if you have constructed a prototype.

What can I say? If this is working then it is certainly something which many people can reproduce. I'd love to see any multi-cylinder designs you may have, now or later, and once more thanks for posting this here.
