For example, at a density of 10 20 particles per metre cubed, the containment time must be one second. To realize a net power output from such a generating station-allowing for plasma radiation and particle losses and for the somewhat inefficient conversion of heat to electricity-plasma temperatures of about 100,000,000 K and a product of particle density times containment time of about 10 20 seconds per cubic metre are necessary. By absorbing those products in a surrounding medium, a powerful heat source could be created. A potential source of heat might be supplied by a fusion reactor, with a basic element of deuterium-tritium plasma nuclear fusion collisions between those isotopes of hydrogen would release large amounts of energy to the kinetic energy of the reaction products (the neutrons and the nuclei of hydrogen and helium atoms). Such heat sources depend on the combustion of fossil fuels, such as coal, oil, and natural gas, and fission processes in nuclear reactors. The major method of generating electric power has been to use heat sources to convert water to steam, which drives turbogenerators. The most important practical applications of plasmas lie in the future, largely in the field of power production.
