Description

Trevor Baylis (b 1937) shown with his wind-up torch. Baylis invented the world's first clockwork radio. It has three bands (MW, SW and FM) and needs no batteries, the power source being an internal spring-driven generator powered by hand. This pioneering work was developed with funding from the British Overseas Development Administration. It is primarily aimed at people in developing countries where affordable energy sources are scarce or non-existent. Winding the handle for twenty-five seconds gives over 30 minutes playtime.
