I was wrong about the lady, in part. Of course, she is wronger, but here is the problem. I mentioned "opposed piston" yesterday because I had done some sketching last year to put another set of pistons on the other side of the "cylinder." I guess my mind didn't comprehend how "free piston" had anything to do with this device and I jumped back onto "opposed piston." Well, as the patent diagram clearly shows, it is neither "opposed" or "free," so the lady was clearly wrong. Now that she is a board member it is also clear that whatever she says should be disregarded as "company talk" so it really doesn't matter. Now here is the really interesting finding from this error. I have carefully read the "opposed piston" site I linked yesterday. Notice this fellow in Denmark has connected two otherwise unconnected opposed pistons with two Honda Synchronous electric generators wired in parallel. No gears, just wires. He claims this keeps the two pistons in "sync." This is remarkable to me. Cornbread, you are an electrical engineer. Does this work? Suppose you put opposed pistons on the OX2, ran each shaft out on opposite sides and connected them to such generators to keep everything in time. Then use the electricity (and heat) generated for co-generation, hybrid auto or just electricity. According to "Nils the Dane," the efficiency would be very high. Maybe that is only for a "blown" 2-cycle, but this rotary piston design can be run either two or four cycle by modifying the cam and adding a blower for the two cycle to get adaquate aspiration. By the way, here is a link to what I have now found for "free piston." solstice.crest.org
