Next year I will have a windmill compressing air to get water from our well with the air-lift method. It will pump into a big holding tank. Then we will irrigate with it. Some can be used for flood or drip irrigation. No problem. But to get some pressurized to run a sprinkler is trickier. I'll have the big tank of compressed air. How can I use that? I had first thought of a small 12VDC solar pump and battery and panel, but the compressed air is right there waiting. Any thoughts? I have alot of ideas, but want to see what someone else thinks up.
