How to turn water into rocket fuel – scientists unlock power of the sun

Scientists have devised a cheap and simple method of turning water into rocket fuel using solar power in a development that could generate a new source of green energy for the home and workplace.

The researchers used electricity from solar panels to split water into oxygen and hydrogen – the constituents of rocket fuel – with a technology that scientists believe could solve many of the problems that have hampered the development of solar energy.

With the help of a simple and yet highly efficient "chemistry set" made out of commonly available materials, the scientists have found a way of storing solar energy as a chemical fuel that can be used to power pollution-free electricity generators known as hydrogen fuel cells.
