article. Their series A funding is complete.  Bill Gates is a major
backer. Don runkle is CEO

It is essentially the same as a 1930's Junkers Jumo 2 stroke
diesel with the  same 2 stroke port timing problems. Therein lie
the problems.

Jeff Spitzer, chief engineer at GA Aircraft Division SD, built a scaled
down copy about ten years ago and had it at OSH. It was rejected by the
AF in favor of a turbo Rotax 914. Even the Germans gave up on it
around 1940.

Here are some Jumo pictures. Also a much smaller version called
the Gemini I saw at Aero in Friedrichshaven in 2009.

Napier built a large 3 crankshaft version called the Deltic. Widely
used in locomotives and boats.

Bill Gates should have checked with me :)

Supertec in Germany are building a high compression diesel version of
the Wankel. A turbo compound of that engine would be unbeatable.

This is the kind of stuff I spoke about at this past Saturdays Chapter
40 EAA meeting. I was, until reading this forum, completely unaware
of the development of the Wankel, and all listening to me were about
the same. Charlie brought up the problems of the Rotamax, I told him
about the silicon nitride upgrade, and the relatively new cart
rotaries in Europe.

People are very interested in these engines. They want to know. Especially about the small ones.
