Q: I made a New Rotary Engine, the only one in the world now!!!!!!!? My brother did developed a new rotary compression engine, very unique. He have background at electric and mechanics, this machine can be used as combustion engine too. Good for race car! Any idea to who to contact with, even for to sell it.
A: You all are crazy :). There are many types on rotary engines out there. The rotary one mazda uses is the WANKEL rotary engine. There are rotary pistonengines out there as well. Search some. Your idea has probably been out for a while. And answerer #2, wankel rotary engines are still in production today. They still have to be good to go into new cars. Get your facts straight.
