  1. The windpump design is much simpler than the one in the above pic. The sails are flexible and catch wind from almost every direction. The windpump only supplements your farm water during the dry months, usually pulling water from a low area and moving it to a high area where it can flow back down through the farm,,etc. It can send water about 200 meters, a little less on a gradual, slight slope. Luckily, Sakon has enough days of wind during each of the dry months at around 11 or 12kmh to supply enouh water.
