Fusion powers stars and produces virtually all elements in a process called nucleosynthesis. The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.
On the sun, where fusion occurs naturally, the strong gravitational pull keeps hydrogen atoms from dispersing. Scientists can do the same thing with magnets, but that comes with another set of ...
Learning from the sun. Nuclear fusion occurs when two atoms of a light element such as hydrogen are heated and fused together to form a heavier element such as helium. In order for that process to ...
Scientists at a U.S. government lab have announced a breakthrough in efforts to create technology that could one day offer humanity a clean, unlimited source of energy.
Various authors have also put forth ways to organize all the fusion approaches that have been tested over the past 70+ years. This flow chart above groups the approaches into color coded families, these are: the Pinch Family (orange), The Mirror Family (red), Cusp Systems (violet), Tokamaks & Stellarators (Green), Plasma Structures (gray), Inertial Electrostatic Confinement (dark yellow ...
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [2] [3] [4]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
If all goes to plan, Virginia will be the site of the world’s first grid-scale nuclear fusion power plant, able to harness this futuristic clean power and generate electricity from it by the ...
At the Sun's core temperature of 15.5 million K the PP process is dominant. The PP process and the CNO process are equal at around 20 MK. [1] Scheme of the proton–proton branch I reaction. The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert ...
