Or flip it over so the armature is stationary and the motor body spins
and you can have a wind-powered propeller clock.

for power, the motor body is spun by belt drive from the spindle

Or you could make a wind-powered LED anemometer :)=20

But there'd be inaccuracy because of the load of the power generated.
