aux power alternator from steam from exhaust?

 Lets say we are crusing down the hiway using 40hp to push thru the
air. Another 40hp is blowing out the tailpipe and another 40hp is
exiting thru the radiator. Exhaust gas temp is 400-500 deg F.... Seems
like that would boil water. If we could recover 30% of that 30KW of
heat in the exhaust, it could charge batteries, etc. Anyone know how
to do this? I think all the steam engineers are retired arent they?

===================================
That's interesting, but not exactly what I'm looking for... more like
a muffler gizmo you weld into the exhaust pipe that makes steam to
spin a turbine and a pma alternator... guess it needs a pump and a
condenser too. Need some sort of a controller to dump load when the
steam pressure drops.

 

That is the kind of hybrid that I am working on ....
The control is called a clutch.....and only really coming into play at start
up.
If the steam drive is separate from the main drive train(like APU would be)
a pressure switch that functions
like a pop off  is enorgh.
The BMW steamer shows just how few steam engineers are still around.
Combined cycles autos,trucks,ships and locomotives of a century ago actually
got a higher percentage of
the waste heat.
Cost in the face of cheap fuel has pretty well held off the addition of
complexity.
Just like ICE electric vehicle drives.

"The engine has yet to operate against a load on a dyno, but his
testing to date encourages Crower to expect that once he gets hard
numbers, the engine will show normal levels of power on substantially
less fuel, and without overheating. "

Another backyard tinkerer who doesn't understand basic thermodynamics
and is repeating the past.

This "technology" is not new.  I see references to it in my dead tree
library as far back as 75-80 years ago.  The Army airforce and NACA
took another look in the WWII era as a method of boosting economy of
both stationary and aviation engines.  Water injection showed some
promise in very large low speed fixed and marine engines but not
enough to warrant the complexity.
