Now physicists in China have announced that their own nuclear fusion machine, called the Experimental Advanced Superconducting Tokamak (EAST), has produced hydrogen plasma at 49.999 million degrees Celsius, and held onto it for an impressive 102 seconds.
The plant, dubbed the Noor 1, is located on the edge of the Sahara in a town called Ouarzazate. The plant covers thousands of acres of desert and generates up to 160 megawatts of power, making it already one of the world’s largest solar thermal power plants.

Doubling the size of a tree only increases the required wind speed by 9%; likewise, using wood more resistant to fracturing (oak versus pine) increased the critical wind speed by less than 10%. The scientists point out that their finding may reflect an optimization over evolutionary time, as wind speeds on Earth rarely exceed 50 m/s. The mathematical relationship could also explain how corals and other sedentary organisms grow in water currents.
New findings from an international collaboration led by Canadian scientists may eventually lead to a theory of how superconductivity initiates at the atomic level, a key step in understanding how to harness the potential of materials that could provide lossless energy storage, levitating trains and ultra-fast supercomputers.
German scientists have just switched on the Wendelstein 7-X (W7X) stellarator – the largest nuclear fusion machine of its kind – to successfully produce and sustain hydrogen plasma for the first time.
