For energy production on earth different fusion reactions are involved. Most suitable fusion reaction. Understanding plasma required major developments in physics. Plasmas are now used widely in industry, especially for semi-conductor manufacture. Advantages of Fusion A vast, new source of energy.
Fuels are plentiful.
Inherently safe since any malfunction results in a rapid shutdown. Radioactivity of the reactor structure, caused by the neutrons, decays rapidly and can be minimised by careful selection of low-activation materials. Provision for geological time-span disposal is not needed. Fuels Deuterium is abundant as it can be extracted from all forms of water. If all the world's electricity were to be provided by fusion power stations, Deuterium supplies would last for millions of years.
