I have access to this decorative windmill. It’s been in place for decades, spins freely in the wind, and has made millions of revolutions in its lifetime. Its RPM’s are impressive even in relatively low wind.
What are your thoughts on how I should harness this energy?
magnets and copper wire?
and a slip ring.
and maybe a sand battery?
or maybe a corkscrew to lift water, as a secondary store of power potential, that could then be toggled on to flow in low wind to keep a turbine going.
