William Kamkwamba: How I harnessed the wind  (script)
Summary
The speaker grew up in Malawi, which is in poor and  experienced famine. He was forced to drop out of school because of hunger. However, he wanted to go to school and  help his family. He thought of building a windmill and pump water for irrigation to help them. Although he used scrap materials, the machine he made was heard to generate electricity so people lined up to charge their mobile phones. It led to the previous TED talk. It led him to having the second TED talk and he gave us confidence.

This is the second time for him to stand on TED talk. I watched first one and I was moved that for two years, his English pretty improved. first talk ↓
