rv6ejguy said:This engine looks like a copy of an engine designed by my engineer neighbor ( the name was Kristensen) back in the early '70s. The prototypes were impressive even back then but funding ran out after a few years. I think he had all this patented before anything about the design was announced. It was called the K-cycle.
Many of the great ideas just never really make it to the market due to funding or other problems. Just look at Zoche, Innodyne even Deltahawk. It takes decades or never in many cases. Even companies using developed core Otto cycle engines rarely seem to be around very long or hose their initial customers so badly that the bad word effectively puts them under.
