The Clockwork Radio The British inventor Trevor Baylis created this really clever ′wind-up radio′ for people from Third World countries. in some parts of the Third World countries, it’s very hard for people to get or pay for enough energy.

When it is fully wound up (上弦), the radio can work for long periods. The clock work product is not a new invention. The Victorians had already put it in wide use. We may find them used in toys as well. Then what is new about this clockwork radio? Baylis has used this simple but effective (高效的) way of creating electricity to both help the people of the Third World and to develop a product which is selling well in Western Europe.
