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.Interesting, no?
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.
Until now the concept has stagnated because it has been too costly and difficult to use solar-generated electricity to split water into oxygen and hydrogen in a domestic setting, but the new method relies on the discovery of a catalyst that speeds up the conversion of water into high-energy fuel.
Daniel Nocera of the Massachusetts Institute of Technology in Boston, said the discovery could remove one of the major obstacles that has prevented solar power from being taken up widely as a viable alternative to fossil fuels such as oil and gas. [...]

I hear there's a lot of water in ANWR . . .
