- I'd worry of hurting the engine. What if the condensed water was used to
- "cool" the engine? That way, you'd recover a lot of the heat used to heat

- I'm looking at diagrams and theorizing how the rotary engine could be adapted
- to steam use. It would mean a having a gear train, in the form of two exhaust
- and two intake valves per rotor.
-
- The advantages of a rotary would be:
- small size (more room for boiler)
- simplicity (albiet offset by the geartrain)
- having one power stroke for every rotation
- (it's essentially a two-stroke, but has two power cycles going at any
- one time)

-
- Some kind of oil, maybe? The Saturn V lubricated its fuel pumps with kerosine.
- I'd be afraid of 1000C flammable gas shooting out of my car if it sprung a leak,
- though.

- A CFC?
