A pump...

The guy stated that it took 1500 strokes from a bicycle pump type mechanism.

Could you imagine the arms that would leave on someone! What a workout!
 
I was curious about that, too. He didn't show a pump, but did say the pressure was equivalent to 1800 (or 1500 or lots of) strokes with a bicycle-like pump.
