please let it play out.
Other than the dubious pricing it has potential. No joke intended.
A French company is building a multi-passenger car that was able to travel ~100 miles on compressed air.

The air pressure was closer to 5K psi, most likely because of the size necessary to fit in a smaller package. Those types of mechanics are much more expensive today. (No market). Hopefully there will be one when we become a hydrogen economy.
georgios' idea could allow for larger containment vessel therefore lower pressures. If he could point me toward an ‘engine’ that would convert the compressed gas to mechanical motion to drive a generator I would be convinced.
I would rather see his ‘turbine’ used in electrolysis and produce hydrogen, but that is ‘tomorrow’.
