I just thought this was an interesting concept. I don't think it's everything he says it is, but I think it's a neat idea. Kinda like some kind of rotary hybrid engine, but yet not. Lol

I'm not sure I believe it could be designed so easily by a few brothers with ZERO idea how to build an internal combustion engine, but its an idea none the less.
