So, more than a decade of unsubstantiated claims, unfulfilled promises and unconsummated deals resulting in assets being secured by the creditors and topped off with a stock selling at about 2/3 of a cent on the dollar sounds like a sound proposition? :-\
If Cyclone is indeed finding out all the ways that you can't build an engine, they will never be able to compete. OTHER companies use mechanical engineering, fluid dynamics, metallurgy, thermodynamics, tribology, manufacturing expertise and other disciplines to develop THEIR engines. Maybe a million monkeys building a million prototypes for a million years will come up with a good engine, but the real pro will have an engine running well on the very first try and refine it greatly in the next couple of iterations. That's how all those people building cars, motorcycles, outboards, lawnmowers and model airplanes manage to stay in business.
Lots of luck with that "fake it 'til you make it", more often it turns into "flail 'til you fail".
