Well, who knows? The IC engine as is has to deal with some pretty serious issues around heat and metals.

The guy who came up with this, Crower, has been in racing for decades -- he makes custom cams for Ferraris among other things. The report I read said that engine really rocked. He's the kind of guy who can bench test for power, etc.

If this thing can actually increase mileage by 40%, and it clearly is designed to utilize waste heat, might be seeing this thing on the road one day. Since exhaust gases contain water vapor, condensers for recovery would have an even chance of recovering enough water to keep going with minimal H2O input.

This thread has reaffirmed what I already knew: don't float my breakthrough ideas until I get a prototype and patent in hand -- that and major $$. People love to tell you that this or that can't be done.
