Have you seen the rotary that Moller International has been working on?  He's
been at it for like 20 years or something.  I think his is based off of an
OMC outboard design.  Anyways, he's supposed to have some kind of super-duper
proprietary seals and coatings that solve the seal and emission problems.
Take a look-see.  Could be all hype, but I think he got some kind of grant
from NASA so there may be something to it.
