The Max Planck Institute for Plasma Physics completed the world’s largest nuclear fusion machine called a stellarator - 16-metre wide machine, which costs US$1.1 billion. The key to a successful nuclear reactor of any kind is to generate, confine, and control a plasma — a gas that has reached temperatures of more than 100 million degrees Celsius.
Because of the stellarators’ design, experts expect it could sustain a plasma for at least 30 minutes at a time, which is significantly longer than competing design - tokamak (about 7 minutes). If successful, this project will make big step towards scientists' dream - a clean, inexhaustible energy source in the form of nuclear fusion. Read more at http://www.sciencealert.com/
