Let’s Build A Windmill

Let’s Build A Windmill

When I entered Malawi, I was eager to meet a Malawian man named William Kamkawamba who built a windmill when he was 14 years old. While searching for that man I met Zack Mwale, a young innovator in Eastern Malawi. After chatting about windmills we decided to build a windmill ourselves that would work to pump water for a community that was currently without any type of water pump. We went to some surrounding villages and met the people of Zandana, a small village of some 25 families who all pull water from a well using a bucket, or walk more than half a kilometer to a water hole to carry water back in buckets on their heads. We agreed with the chief of the village that it was a good place to install a windmill. After weeks of designing, finding materials, building and redesigning, we successfully constructed a windmill that pumps water for use in the village (see video above). This rewarding experience has been an inspirational one for myself and the people of Malawi, most of whom have never seen a windmill before. Zack and I look forward to seeing what this windmill leads to in the future, hopefully motivating other communities to look to the wind for clean energy.                       Mchinji, Malawi 7/9/17 to 17/10/17

After hours of searching around the market in Lilongwe, Zack and I struck gold when we found this old gear set that used to work for a conveyor. We used this for the critical function of the windmill gearing.Zack negotiating timber prices  Digging holes for the water tank standWind blade layout The people of Zandana helping to move the tower

When we strapped this 1000 liter water tank to Zack's little car, we had to drive at night to avoid the inevitable police bribes that would follow.Digging the water well Building our gear set for the windmill Constructing the tower Some of the children of Zandana around the well

A big thanks to Zack Mwale and his family and friends for all their support, meals, and good times. I thank the people of Zandana for all their help throughout the project. Thanks to Delick, Halice, Jablos, and Mr. George for all their help and patience. If you are interested in what to consider in building your own windmill, reach out to me through my contact page.
