Yes Albert, it *is* the difference in pressure between
the input and exhaust that does the work.

So we have now reduced the input to 0.5 STP to
make it easier to boil. So lets say the condensation
reduces the pressure at exhaust to, say, 0.25 STP.

How have we gained anything over your common or
garden variety turbines where the energy input into
the chamber increases pressure to above STP
with the exhaust operating at STP?

Or to simplify the question to a point where even a
fan of Savage may understand it - what makes
(0.50 - 0.25) bigger than (1.25 - 1.0)?

Its the energy coming into the system that produces
the pressure gradient to do the work. Not the starting
pressure of the input chamber.

And what is feeding energy into the input chamber
in the first place? If we are feeding STP 80 degree
seawater in, what is keeping the input pressure down.
You can't condense it all away to zero you know (and
its coming in condensed in the first place).

Hence my reducto ad absurdum. If a turbine operating at
less than STP can produce more energy for less input
that one operating at STP, surely one operating at zero
pressure can produce unlimited energy out for zero energy in.

Or for the utter scientific illiterates who take Savage seriously ...

Has it occured to any of Savage's fans that there may
actually be a reason that none of the regular steam turbine
generators used the world over run at lower than STP?
Surely if there was anything to be gained here, some
engineer just may have twigged to it by now. Maybe its
a conspiracy by those of us who have actually bothered
to learn something about physics (e.g. the mechanical
and structural consulting engineer who reviewed Savage
at http://tinyurl.com/36hwy ) to hide our slow wittedness.

However I note that a 14 year old (who presumably
has not begun to learn basic physics yet) found the
book "well written enough for me to understand completely".

Am I talking to anyone older than 14 here?
