A German nuclear fusion experiment has produced a special super-hot gas which scientists hope will eventually lead to clean, cheap energy.

The helium plasma - a cloud of loose, charged particles - lasted just a tenth of a second and was about one million degrees Celsius.

It was hailed as a breakthrough for the Max Planck Institute's stellarator - a chamber whose design differs from the tokamak fusion devices used elsewhere.

The Sun's energy is created by fusion.

Physicists are in a worldwide race to create stable fusion devices that could not only mimic the Sun but release abundant energy, without the volumes of toxic waste generated by nuclear fission - the splitting of the atom.
