Re: Flash Evaporation?

Yes, that's one of the sites I looked at when researching this. It seems quite feasible, but I'm not sure how much energy it would take to get enough vacuum to boil water heated by the engine. I know you can get water to 150 degrees or so pretty easily. You can look up the pressure at which that would turn to steam. What I haven't found is a way to estimate how "big" a compressor you'd need. They seem to rate them by flow. We need to know how fast they can take a given volume of air down to a certain pressure, and how much power they'd draw doing that.
