In 1993, Englishman Trevor Baylis designed a windup radio that does not need electricity. He hoped his invention would help spread information about AIDS prevention and treatment in Africa’s rural areas. But when he approached manufacturers, they rejected his invention, questioning its commercial value. Eventually, he got the radio into production in South Africa, where a local investment firm decided to fund it.
