And with a skinny PVC pipe running down into the water of the well acting as a straw the 25lbs of air-pressure or so would pump a steady stream quite high as needed into an over head tank. It works great and is almost absurdly 'low-tech.'>>
Yup this is what I was getting at. I wanted to avoid converting the wind/sun/waves/tide etc into electricity which is then stored in a battery or used to pump water uphill etc. Direct conversion of renewable energy into stored mechanical energy would cut out the "lossy" middlemen stages.
