Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen, “fuel cells”for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2billion in the production of hydrogen fuelled cars.

　　The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by­product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth 's population that has no electricity.

　　And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light,

　　they can work long into the night.

　　Some scientists see radical changes in the way the human race co­operates. Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world­wide hydrogen web”， which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
