There are others also.



To prevent going to much OT in rec.auto.tech, if you wish to discuss
engines other than car engines, there is a Yahoo group called heat
engines, for discussion of any heat engine, IC, steam, or other.

http://groups.yahoo.com/group/heatengines/

You can access it as a web discussion group, or you can receive and post
via email.

We'd be happy to see more folks join, and liven up the discussions.
