Let me add my voice to the chorus of those happy to have you here, Ed.

Personally, I'm a member of both lists, and I take everything EITHER =
side says with a grain of salt. Paul does often have a one-sided view of =
things, but he is still full of useful information, and they're =
currently debating a muffler design that looks very interesting to me. =
On the other hand, if the EWP works, it works, and I'll be happy enough =
with that. Cooling the rotary has turned out to be as much art as =
science anyway, since nobody has the perfect answer yet.

For what it's worth, my view is that Paul is very much a theoretician - =
he likes to prove his cases before he starts experimenting. The EWP is =
more "bucket chemistry" - toss some stuff into a bucket, and see what =
happens. Look, we didn't even have accurate data on impeller flow =
obstruction. In response to my e-mail the makers said the flow should be =
almost unobstructed, but (was it you, Russell? I forgot already!) =
somebody already showed that this is NOT the case, so we're back to =
talking about check valves and parallel setups.

There's enough that's unproven here that I'm acknowledging that I'll be =
taking a bit of both styles as I put this together. Then I'll test the =
hell out of it. And no battles.
