hmm - I think I should hand back all my degrees because obviously you are on a GOD level of chemistry and physics.
So explain it to us "earth beings" where the gravity is 9.8 ms and water is in liquid form while the absolute atm pressure is 1 bar.
On our planet if we compress or super cool a gas to become liquid we had to name this process - it called liquification. Now being the humans we are - (keera to find out) we tried this on different gases and those pesky ******** have different pressures,
Now to cut short - we earth beings have come to this result Liquid hydrogen - Wikipedia, the free encyclopedia
This is the only way Hydrogen can be used as "FUEL" for an engine - because your paani ka glass and breaking up water attempt of "fooling people out of money" cannot even dream of supplying such BTU energy as liquid H2 will (on which the BMW hydrogen7, rockets etc works)
I also doubt your paani ka glass system will ever cool down the produced h2 to -260C.
Please go ahead and kindly explain how does your planet deal with this issue? Loss of pressure? loss of Gravity? atmospheric temperature is -260C or is everyone called mary jane?
