up Radios - Daniel talks to Trevor Baylis, the designer of the windup radio. The radio will initially be used by aid agencies in remote areas such as Rwanda and Sarajevo, where people do not have access to batteries because of expense and availability. Owners of the radio will only need to wind it up for 20 seconds and it will play for 40 minutes. This new invention is being manufactured by disabled people in South Africa. Bayliss says demand for the radio is high worldwide.
