Fusion may be the future of clean energy. The same way the sun forces reactions between light elements, such as hydrogen, to produce heavy elements and heat energy, fusion on Earth can generate electricity by harnessing the power of elemental reactions. The problem is controlling the uniformity of hydrogen isotope density ratio in the fusion plasma—the soup of elements that will fuse and produce energy.
A research team in Japan has reached a key understanding of this process that may aid the future development and use of fusion plasma.
They published their results on Jan. 14 in Physical Review Letters.
