- A few of the netters on sci.energy and I are talking about external-combustion
- engines for cars and trucks, and one of the problems we're encountering is the
- fact that water can freeze. Also, very hot steam is corrosive.
-
- I read about a steam-like engine that used "an organic fluid several times
- heavier than water." What could that have been?
-
- What kind of compound would you suggest? A few criteria:
-
- Liquid at room temperature
- Doesn't freeze during wintertime (under 30 below, to be safe)
- Boils at a reasonably low temperature (like water)
- Isn't corrosive at circa 800C
-
- If possible, serves as a lubricant--even at 800C temperatures
- (Is it even possible for a gas to be a lubricant?)
-
- Thanks for helping us out!
