> When you say small turbines do you mean ones attached top a generator?  Bellow are great for intense bursts of air but maybe not for sustained air flow.  A number of years back we(the museum I was with) built a "kid-powered" component for an air display and we used a large squirrel cage blower with the motor removed and a hand crank added. The output was stepped down to a 1-1/2" dia opening as we were pushing ping pong balls up a 12 foot tube.  Adjacent to this was a bellows to do the same thing.  With the hand cranked blower you could move the ball in a steady speed to the top while the bellows required 2-3 very quick repeated pumps because it would drop back a bit on each pump.  It really showed the difference in the two sources of air power.
