William Kamkuamb was born in the state of Malawi, which is located in Africa. When he was fourteen years old, a terrible drought hit the village where he lived. People had nothing to eat and drink. Being an excellent student and very fond of physics, the guy decides to save his native village from starvation. In the library he finds scientific books on physics. Unfortunately, they were all exclusively in English. But the hero did not give up. For a long time studying pictures and different symbols in Latin, the guy got an idea to build a wind generator.
