Paul,
Not knocking the turbo compound concept.
I wonder how soluble oil in the water would burn - must test that one.
I have no answer to distilled water costs and I guess it's dearer
than fuel
at the moment - but what about later!
We are at $1.43 a Litre here locally ( 3.6 L to the US gallon) and
we are
.77 cents in the US dollar = $3.96 a US gallon.
I'm sure we have gone past the point where alternative fuels ( like
hydrogen) aren't cost effective to manufacture.

George, et.al.
Just read an article on methods of NOx reduction in ocean going
diesel powered ships:
http://www.marad.dot.gov/NMREC/energy_technologies/images/Emission%20Reduction%20Technologies%20-%20Matson.pdf
Some methods include injecting atomized water into the intake. This
is also beneficial in reducing air temp from in a super/turbocharged
engine. My thought is that impurity Corrosion is more of a problem
in generating steam as apposed to running it thru the combustion
process.. However, the impurities in the water injection may cause
increased wear inside the engine, and, the article mentioned that it
may have a washing effect on oil lubrication in 2 cycle engines.
Disclaimer. My only association with steam engines was to watch
them go by the back of the house when I was a kid (WW-2). That's
also when I decided I wanted to be an engineer. Then when I got to
college, I found out they didn't have engines there, just math,
chemistry and physics classes, ugh!
