| Details |
He Changgen, 56, Fenglin, JiangxiChanggen was worried about the fuel shortage at the petrol station that he worked at. After a lot of research and help from his brother, he devised a novel generator. Since 1992, he has been granted seven patents. The generator is not dependent on the local power grid. It converts kinetic and electromagnetic energy into electricity. It is intended to help solve the energy crisis and is both easy to clean and energy-efficient. Fertiliser distributorBaoyuan Liu (Huhe Wenduer, Inner Mongolia)Baoyuan Liu, a farmer, had experienced that many of the agricultural farming machinery are not convenient to use and are also laborious for the farmers. He therefore began improvising these machines. By 2008, he had made multiple modifications. Most of the farming tools modified by Liu are practical, technologically advanced and easy to use. They also save a lot of time and labour, especially the fertiliser drill. It is an all-weather device and can cover an area of 40 acres a day. It is also inexpensive. Liu has till date made modifications on the backhoe with wheels, rakes and other farming tools. The wheel gears designed by him are also unique. The farming tools and devices modified by him are well received by the local farmers and he now is almost a celebrity for the villagers. People are eager to use the tools modified by him.China and IndiaCotton separating machineThe cotton separating machine developed by Mei Xiaokun is simple, cost-effective and easy to operate. When the cotton pods are put into the machine, the cotton is separated from the shell and comes out through an outlet while the empty cotton shells are thrown out through another outlet. The machine can easily separate about 150 kg of cotton from the pods, as compared to only 10 kg manually. This machine has greatly improved efficiency and drastically reduced the production costs.A similar machine has been developed by Indian grassroots innovator Mansukhbhai Patel. The cotton-stripper machine developed by him saves the cost involved in manual labour and eliminates drudgery for women and children. It processes 400 kg cotton per hour and also improves its quality. The machine is available in two models and is available with suction feed as an auxiliary attachment. |
