【题目】 Have you ever heard of “a ball of energy”? People often use it to describe very active children. But today we tell about an invention called the socket, that is a real soccer ball of energy. Julia Silverman explains that in fact the socket is a portable generator.

Julia Silverman and Jessica Matthews developed the socket as part of a group project for an engineering class at Harvard University. There are mechanisms in a socket. When you kick, hit or throw it, energy is then kept in it by these mechanisms instead of disappearing into the environment.

Then the user can put something directly into the ball, like a lamp, or a mobile phone charger so that they can get energy from it. For every fifteen minutes of the game play, the socket can provide enough electricity for an LED lamp for three hours, and the ball can store up to 24 hours’ electricity.

The International Energy Association reported last year that nearly one and a half billion people in the world had no electricity to use, and most of them live in sub-Saharan Africa and in India and other countries in Asia.

Julia Silverman and Jessica Matthews both had experiences in developing countries before they began the project. They knew that power shortages are a serious problem in really areas. There’s an energy crisis in the world. One out of every five people in the world don't have any electricity, there are a lot of health problems because what people use instead of any electricity are harmful choices like kerosene lamps, which produce a lot of smoke.

Julia Silverman says the socket ball is one small solution to a big problem. Jessica Matthews and Julia Silverman hope their socket ball will shine more light on the problem of power shortages. It offers people a chance to put their energy into the world’s most popular sport and get some energy in return.
