Milestone: China's artificial 'sun' becomes six times hotter than real sun

The downside is that they could only maintain the state for about 10 seconds which means we are a way away from fusion power yet but the Chinese do have experimental evidence that reaching the 100 million degrees Celsius mark is possible.

In the process of nuclear fusion, two hydrogen atoms will combine together and produce a stream of clean energy.

Experts believe that the newly developed China's artificial sun will soon emerge as a cheap and clean source of energy using nuclear fusion.

If nothing else, it makes for one hell of a microwave.

The major problem with nuclear fusion is the conditions required to create it-extremely high pressures and temperatures of around 150 million degrees Celsius (270 million degrees Fahrenheit). Scientists at Google and the Massachusetts Institute of Technology (MIT) are now working on their own nuclear fusion projects as well.

Scientists at the Hefei Institute of Physical Science, which is part of the Chinese Academy of Sciences, have been working on an experiment to achieve nuclear fusion since 2006.

China's Experimental Advanced Superconducting Tokamak, or "artificial Sun" as it is better known.

Tokamak reactors hope to generate fusion energy from a plasma trapped in a magnetic field - but the key to igniting the fusion of hydrogen atoms into helium atoms is temperature.

The temperature at the core of the sun is said to be about 15 million degrees Celsius, making the plasma in China's "artificial sun" more than six times hotter than the original.

Associate professor Matthew Hole from the Australian National University told ABC: "It's certainly a significant step for China's nuclear fusion program and an important development for the whole world".

Nevertheless, the race to build a fusion reactor is hotting up, with numerous companies now devoting resources towards developing a successful method.
