a breakthrough in computer design could lead to computer technology being available in the poorest parts of the world. An IT company has developed a laptop computer that will only cost $ 100. It has all the functions of an ordinary computer including WiFi and 1GB of storage. Since the price will be low the designers hope that the laptop will be available to children in poorer parts of the world. The computer is powered by turning a handle and, as a result, it does not need an electricity supply or batteries.
