Farmer Aiem Sompeng has just a rudimentary education, but curiosity and necessity drove him to design the energy-producing wind turbines that are now a landmark in his village of Dongyang, in Yasothon's Maha Chana Chai district. Like many rice farmers in the northeastern province, the 66-year-old Mr Aiem was trapped in debt incurred by the high costs of fertiliser, pesticide and electricity needed to run irrigation pumps, as well as uncertain prices for his crops.

Drawing on his knowledge of carpentry, he began designing his first wind turbine in 2009 with the intention of reducing his electricity costs. He now has four turbines that he uses to draw water from a well to irrigate his 23 rai rice and vegetable farm. The first wooden frame he erected wasn't strong enough, so he switched to a concrete pole. The blades were made of fabric, plywood, pieces of old zinc roofs and other materials found on his property.
