I'm curious about the efficiency of compessing and storing
air with windpower.
As compared to batteries, in the end still needs to be converted to
electricity. Storage dosen't wear out. What about efficiency of air turbine
driving generator vs. battery driving inverter?

Converting windpower to compressed air to electricity just adds one
more stage (at least) of conversion. Every stage, no matter how
efficient, results in a net loss of energy. Best to go direct. Wind -
electricity.

Never mind that compressed air will have to dump lots of heat on
cooling back to ambient.
Lousy way to store energy.

It takes batteries to store electricity. More
conversion processes to store it as chemical change and
back.
Air pressure is a storage method. Compare apples with
apples.

I heard about someone using a waterpumping windmill driving an above
ground water well cylinder to compress air. It supposedly worked very
well. I don't think leathers would work long term though without oiling
them frequently. I'm sure this would be a lot more efficient than using
a wind generator.
