The numbers do not appear favorable for launch.
450*60 = 27000 lbf! I think that is quite some power, unless that is the wrong formula!

27,000 lbf would probably be enough to move a big-rig! I wonder what would happen to the ball!

Just remember: The compressor is a decent-sized motor in charge of storing a ton of energy as compressed gas. Over time, this power builds up until you have stored, for example, 100 watts of energy which you release it within a second! I think that would be:
100w*60s*60m = 360,000 watts per hour are delivered!

THAT IS DANGEROUS!
