Inventions for the modern world
How would you use a radio or a telephone if you had no electricity or batteries? These problems bothered British inventor
 Trevor Baylis. So in 1996 he invented a wind-up radio. It doesn’t need electricity or batters. You wind it up by hand. It plays
 for about an hour. Then, you wind it up again. Today it’s manufactured in south Africa. Then in 1996, Baylis invented a mobile
 telephone that is powered by shoes. The shoes contain a small battery that is powered when you walk. This battery is
connected to a mobile phone. These two simple inventions can bring modern communications to all parts of the world.
  Baylis doesn’t have a university degree in engineering. In fact, he left high school before graduating. He just loves making thing
to help people. He never knows when ideas will come to him. He got the idea for the radio while watching TV. the idea for the
 telephone came to him in a dream.
