Not sure if that was about my reply or the thread.

its useless in my opinion. Not sure if you guys know about the "air powered minivan" that was gonna be the future about 10 or so years ago.. Yeah it never left the development phase.

thats what ive been saying for the past posts. useless terribly inefficient. and they have no torque so on a hill, out of luck.
Its possible, just how is the question.
Paintball tanks hold about 3000psi of air ( super high end ones can hold 4-5k)
But there small as hell and will get you maybe a mile of range.
Maybe a vacuum system might be better? Since you will not lose at much over time

look even with psi at 3k, its still not much potential energy.... The power is immense, but the total potential is nill. Power is energy / time, so you can extract all that power instantly in a split second if the container explodes like 1,000,000 watt seconds for 1 second, but the stored energy is probably 50 watt hours.

I'm pretty sure a vacuum one is worse.
Just because atmosphere is about 1 bar, and a vacuum would be 0 bar if i'm right, but 3000 PSI is 206 bar, so thats holds 206 times the "energy"

vacuum one is pure garbage. would barely even have enough power to lift a paper.

look man even 3000 psi wont work. An air compressor lets say is 1000 watts to pump up a tank to 200 psi in around 1 minute. So to do 2000 psi would be 1000 watts at 10 minutes, which is 1000 watts * 10minutes/60minutes in an hour = 166 watt hours of stored energy. Now, because the compressor is lets say 50% efficient, as only 50% of the wattage is converted into pressurized air, that reduces the stored energy to 88 watt hours of a 3000psi tank.
You can use PV = N * R *T
where pressure x volume = moles x avagrodos constant (0.8206) x temperature but i am too lazy to do that and tell you the exact amount. I am just doing rough approx above.
