I want the world to have this information at no cost. I don't want to
type it again so will forward a copy of my letter that I sent to Dr.
Aspden for your list.
Enjoy, Sincerely, Boyd Cantrell

Put a Heat pump that uses ammonia on the left end of a shaft. Now put
a Heat engine that uses ammonia on the right end of that shaft. Thats
what Dennis
had.
He expected the Heat pump to drive the engine and have power left over.
He did not understand that the efficiency of the engine was the
reciprocal of the COP hp. of the Heat pump.
It won't work that way but it will work if you add a Condenser for the
Engine and remove heat from the condenser by using the input of the
Heat pump.
When the ammonia leaves the Condenser on it's way back to the
Compressor it should first go to an atmospheric heat exchanger to
absorb heat in an
amount equal to that which was converted into work and was used
elswhere.
Originally that Compressor got all of it's heat from the atmosphere
but that Compressor doesn't care where it's next heat is coming from
so let's take it where it can do some good.
Fact, The Heat pump now does two jobs for the price of one.
Fact, A Condenser doubles the efficiency of a heat engine. ( Check
it out).
Fact, We can expect up to 70% of what the Carnott equation gives for
the efficiency of an ideal heat engine.
Fact, We can expect all of what the Carnott equation gives for the
COP hp of a Heat pump because all losses manifest themselves as heat
and boy do we
have good insulations these days.
I would expect the first working model (if using a one Horsepower
Compressor) To power itself and deliver about one tenth of a
Horsepower to be used
elsewhere.
Condenser doubles efficiency ? The first steam engines (by Thomas
Newcommon in 1712) worked on vacuum only . then came James Watt. He
used steam pressure. Then came The Condenser equipped engine using
both .
Today we have vacuums as high as 28.5 inches of Hg. Thats not
difficult to believe when you know that when water first starts to
boil it expands 1676 times, so it's easy to see that when it condenses
it must contract 1676 times.
Let's say that a non-condensing engine has an efficiency of 15%. Now
we power it with heat from the atmosphere by using a Heat pump.
The COP hp will be the reciprocal of the efficiency (15%) or 6.66 .
Ok, what goes up comes down= no gain but when we use the intake of the
Heat pump at no extra cost to create the cold reservoir (as per
Kelvin-Planck )
Then comes the vacuum on the exhaust side of the engine. Guess what
? We finally did it after 170
years.
