Because it would have to be far too powerfull. You want to put in in 10
minutes the energy you get out in 1 hour. Then you want about six times
the motor power (neglecting losses). A small car will have 20+kW (is
20hp), so you want 20*6=120kW. That would be a rather large wall wart I
think, even if you don't have to remove the heat from the compressed air
(but you have to or bad things will happen).
