Plot

Born in Kasungu, Malawi, William Kamkwamba is a young schoolboy who comes from a family of farmers who live in the nearby village of Wimbe. William also dabbles in fixing radios for his friends and neighbors and spends his free time looking through the local junkyard for salvageable electronic components. Although he is soon banned from attending school due to his parents' inability to pay his tuition fees, William blackmails his science teacher (who is in a secret relationship with William's sister) into letting him continue attending his class and have access to the school's library where he learns about electrical engineering and energy production.
