Has anyone heard of a U. K. company by the name of Advanced Innovative Engineering (AIE). I read that they have a rotary engine of their own (no, not a Wankel) and have a car running with their technology and tout that their technology has potential uses for generators, boat engines, and the aviation industry.
Plus they say similar things as Coates including using little oil, creating little emissions, and better fuel efficiency.
I wish I was technology savvy enough to get the article to this website, but I read it on Foxnews.com.
I don't know anything more than what I read, but it sure sounds like a Coates competitor.
