not really !!
its true that at .75 atm 1 liter of HHO has fewer molecules
by volume than it would have at 1 atm , but the number of molecules produced increases in .75 atm using the Faraday formula that I used.
this is because the water itself has not expanded because of the lower .75 atm pressure as water
does not stretch because of pressure or vacuum until it can vaporize , and if it vaporizes its no longer water its water vapor.
so your still producing a larger number of molecules.
only it will fill a larger volume in a .75 atm atmosphere.
like a balloon expands bigger and bigger as it rises higher
and higher into lower and lower pressure in our atmosphere , until it expands so much that it explodes.
the same amount of gas it just fits in a larger volume.

the gothermal system was built by me.
I traded the use of copper for the economicaly priced pex tubing used in
geothermal floor space heating systems , I have 100 ft of the pex tubing
apx 25 ft inside a shallow well that I use for the garden.
I put the well down using water pressure !! and a 3" pipe with a city water
pressure hose attached at the top.
then I pumped off the well basin with a 3 hp air compresssor , simply by
running the air hose down into the well pipe and valving the air on and off
the air pressure builds up and then shoots a sand and water mixture up and out of
the pipe.
the circulation is done by a 1/40 HP circulation pump that uses apx 50 watts.
the heat exchanger inside the house is a commercial type heat exchanger
that circulates the cold transfered into the pex pipe in the well.
and the blower fan on it uses apx 200 watts , I have also installed a
roof mounted attic vent fan that removes the hotter air that was being
trapped in the attic.
the attic vent fan uses apx 50 watts
50 + 200 + 50 = 300 watts !!!!!
its funny because I use the cfl light bulbs also
and my geothermal system uses less energy than the lights !!!
alot of these systems use pumps to actually lift water up from a well
then circulate the cold water through a heat exchanger then they dump the
now warmer water back into a seperate well.
this method waste energy as simply circulating the water does not require the additional energy required to actually lift the water.
