German Fusion Reactor could get twice as hot as the Sun

 
Scientists are planning an upgrade to the Wendelstein 7-X stellarator that could allow it to generate temperatures of 30 million degrees centigrade (54 million degrees Fahrenheit). Analysis of the earlier experiments shows they can adjust the Stellarator’s magnetic field cage to prevent a variety of heat loss known as neoclassical transport. Physicists think such adjustments can prevent enough heat loss to double the Wendelstein 7-X ‘s heat output.
