I like open source design -- let the money be earned by actual production. Patents take too long, stifle innovation, and add needless bureaucracy.
No takers on the 2-stroke design I proposed a few pages back? Could it be 2-3X more efficient that current internal combustion designs?
How can fuel best be used to spin a shaft? Does the Revetec engine or the Garric have any merit? What about the other rotary designs mentioned in this thread, so far?
What can we learn from steam and from electric motors?
