The 6-stroke motor looks like an obvious chance to get into race/aftermarket. If it delivers the promised gains on track, I see no reason why it couldn't make progress. I may look into that some more...

The rotary valves are good too and, again, don't seem to be an impossibility to make into an aftermarket kit for, say, Ford Pinto, SB Chevy, Ford 4.6. The concept of using ceramics in rotaries appears sound but the rotary engine is never going to take over from the piston engine.

It's a mistake for an inventor to walk right up to a car maker and hope their idea will be bought/adopted. The industry probably hasn't worked like that since the 1920's. Any new-tech - however well-founded - is a huge risk for auto makers. Frankly most "save 10% gas mileage", "go 10% faster". "save 5 components", "save 2lbs" propositions don't add up when you look at the pre- and post-manufacture supply chain investments required. Then there's the Unions in the plants making the thing you're trying to replace to overcome. Etc. etc. - few of the barriers to market entry have much to do with the technical merits of inventors' ideas. It's a shame, for sure - a whole load of great stuff isn''t coming through to the man in street.

If you can organically grow your own supply chain, then it's different.

Thanks for your good wishes - in 3-4 years you may even find a second hand 'Stang with a ZS box already in it...
