How about a pull rope. Maybe a air motor or a hydraulic motor but then you still need to turn the compressor and the hydraulic pump with something. If you ask a better question I'm sure you could get a better answer.

Water wheel. Like on the old grist mills

Donkey powered - you have seen that on old westerns to lift water out of a well.

Wind w/ Windmill

Water through a turbine (hydro electric damn)

Magnetic forces.

Put a crank on it at turn it by hand?

Hamster in a wheel?

Centrifugal force.

Heat and magnets.
