This is a picture of most current design of a thermal equal engine. A
thermal equal converts heat energy into mechanical energy. Why I call
it thermal equal is that it convert heat energy with out a heat
difference or in other words a environment that is at the same
temperature .

to do this the engine must generate a heat difference by compressing
and decompressing air. A cadrotic Stirling engine is the part that
converts the heat energy to mechanical energy. enough energy has to
converted to over come the resistance of friction of move the gas and
moving parts. The pressure differences is great . 100 pis at the
lease and 5000 pis or more at the max. The fiction of the moving the
gas has to move than the moving parts. this means a great deal of gas
has to move. This is why the base pis is 100 or more

For many years I searched for energy source that would not run out.
The only two for vehicle l could tap into, solar and ambient heat
energy. Solar has it's draw backs. Taping into ambient heat energy is
big unknown.

To figure just how high to pressure needs to I need to rely on
pneumatic flux theory.

The engine has total of three pistons minimum.

which is the compressed, the power piston and the decompressor.
also there are two different circuits. the Compression and
decompression circuit and the heat differential engine circuit
the engine works like this. The compressor compress the gas up to 100
bar. My best estimate is that the gas temperature will increase by 14
degrees and heats up the surroundings. Then the gas goes through a
decompressor and cools by 14 degrees and returns about 90% or less of
the energy uses to compress the gas. then the decompressor piston
pushes the gas out and through a heat exchanger. The reason is that
we want make the gas is warmed up to ambient temperature. If the gas
enter the compressor cool means the compressed can not compress the
gas as much which case a smaller incerces in temperature and decrease
in temperature in the decompress which means the engine converts less
energy and performance goes down.

the heat differnail curiut works like this. the gas in the gas jacket
that surounds the compresser warms up and presure builds. some of the
gas is let into the piston camber explands cools and pushes the power
piston. The gas is push into the air jacket the srounds the
decompresser. a pump push the gas through heat exchange where the
gases absorbs heat and back into the hot air jacket.

I want use methane for the compressor circuit becuse it has high
molar specfic heat. Also methane became liquad at very low teptures
which would give me the the lowest stall temperature possible. Also
if I use freon I have toi add anther decompress pistion and the
engine becomes more comcatied.
ambient heat engines seem to violate the second law thermodynamics
but they don't. Even through we are coventing energy each them the
energy is recycle it take up more space and is harder to convert the
next time. Volume+from/Energy=entropy. Entropy is how easy to convent
one form of energy to a more order form. We can conclusion that there
is threshold entropy number or threshold temperature that is required
for an ambient heat engine needs to work. If the temperature drops
below the limit the ambient heat engine can no longer convent more
energy than what it losses in fiction to keep it going. other words
it will stall.
