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. This radio uses no batteries (电池) and does not need any electricity to run it. A clockwork generator (发电机) is put inside the radio and works as the power. 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.

Even former President of South Africa, Nelson Mandella has one of these radios and personally recommends this product to others.
