The name “artificial sun” was given because the aim of the device is to generate energy like the sun. Under high pressure and high temperature, fusion reactions will take place from inside to outside of the sun. Such fusion reactions will give rise to a great deal of energy to enable to sun to continuously emit light and heat. However, fusion reactions on the sun are uncontrollable and destructive, just like h-bomb explosion seen on the earth. EAST serves to transform such energy into a stable, sustainable and controllable resource. The hydrogen isotope extracted from one liter of seawater can produce energy equivalent to 300 liters of gasoline through complete fusion reactions. (Photo/Xinhua)
