RE:Water Cooling

Scott - actually I was thinking of indirect cooling of intake air, but it would
work quite well with direct injection.

Randy, you seem to know enough to be dangerous. *>)

 If we want to get really technical here, the "vapor" from a humidifier is not
the same as steam. It is a very fine dispersion of liquid water - i.e., a mist
(or in the boiler vernacular, a "quality" of ~0%). As Scott pointed out, the key
is EFFICIENT conversion of liquid to vapor (true vapor). For this, you need a
large surface to volume ratio--both in the separating barrier and the fluid to
be boiled--and a decent fluid transport mechanism. Usound humidifiers do a
terrific job of producing a fine mist. Fluid transport and s/v of tubing is
taken care of by proper design.

I think that is .04c so far.

Ideally, shouldn't the mist evaporate while on the IC and before leaving it?
  Does it matter how small the droplets are as long as they phase change?
Finer droplets have a higher surface to mass ratio, wouldn't they phase
change more readily, before exiting the IC?  A finer mist might cover a
larger area too, for the same amount of coolant.  How about a water/alcohol
mix?  Really officer, the keg is for the intercooler.....
