In this TED Talk, young Malawian William Kamkwamba describes how he built a windmill to power his family's home aged 14, during a time of poverty and famine. The windmill produced electricity and was built from spare parts and scrap.
This moving tale of an invention that changed a young boy's life is a powerful testament to the benefits of education, access to knowledge and self-belief.
