Wind Mill Water Pumping - How, Why, and How Much
I find that after a bit of experience in off the grid concepts and living, a windmill water pump is one of the best ways to go when it comes to dependable electric-free water supply. The action of the windmill is capable of being used for either driving a water pump, or for generating power, and usually not for both. On the upside, they can pump enough water to irrigate any farm. On the downside, if you just need a little water, it might be a bit of overkill considering the costs. There is an up front cost in drilling and casing a well, and then another cost in the windmill pump. The nice thing is you don't have to worry about having a power pole brought in which can be a big expense in rural areas. It is a completely self contained solution. Determining the size you need, you can go all the way up to a large size that will pump water 1200 feet deep in great volume. Watch these videos. Both are terrifically informative. ~Dave Webster
