Dear Mr. Lamar,

The Rotary Engine newsletter has been a valuable source of real world
information.

My background in rotary engines is I'm trying to design one - an extension
of the Wankel principles.

At the moment, am quite a bit away from freezing the design. However, in the
future, when I am in a better position - design wise and financially, would
you be willing to consider critiquing the design?

My priorities are 1. to freeze the design; 2. to try and patent it; and then
the great unknown.

For communication and discussion of design (if you're willing, of course),
do I use the "rotaryeng@earthlink.net" or would you have a different email
id that I could write to?

Also, your views on this material in the rotary context would be
appreciated:

This carbon material looks good for rotors. Somebody ought
to try it but a 30% weight savings is not much.
I wonder what the cost is? The cast iron rotors
weigh 9 pounds so 2.7 pounds off the rotor
amount to 5.4 pounds off the engine.
The cost per pound could be real high.

Hi Paul and Chandra

Paul I understood the 30% weight saving was over
aluminum not Cast Iron making the weight saving much more significant.

Ops. Your right. Thanks for catching that Steve.
That would be a significant weight savings.
