Engine Design: This site is a good history of rotary steam engines. Since 1795, hundreds of engineers and inventors with thousands of patents have attempted to design a viable rotary steam engine. None worked. The moral of that story is just because something is designed and patented doesn’t make it a marketable product. Everything works in animation. Machines, like God, are not a respecter of persons and the laws of physics, mechanics, and thermodynamics are not to be violated.

Recent engines that, in my opinion, have serious or fatal design flaws, are Cyclone, MYT, RadMax, Iris, Quasiturbine, Rotoblock, StarRotor, Doyle, Liquid Piston, Hartfield, Kugelmotor, Vengeance, GoTek, Rotary Vee, and the Russian YoMobile, to name a few. None have ever gone into production though huge amounts of money were invested, with YoMobile ($1 Billion) and Cyclone l($65 Million) leading the pack. The only non-conventional engine to be saleable in the last 50 years was the Wabkel, with over $200 Million in licensing fees, and it has been shelved, although small versions are being used for UAV’s. Even proven designs with 20 years R & D like Achates, Duke, DynaCam, Deka Stirling, and Eco Motors have never broken into the automotive market. It would take $2-3 Billion for a car company to tool for a radical new engine design, and that makes them hard to convince.
