The energy produced by the fusion reactor will be immense, much greater than that produced by the combustion of coal, oil or gas. With one gram of fuel (Deuterium and Tritium), the reactor will produce energy equal to the equivalent of burning 8 tons of oil.
The fuel needed for the future fusion reactor to function is abundant on Earth. Deuterium is extracted from sea water where it is found in a concentration of about 30 g / m3; Tritium is extracted directly from the lithium reactor. Lithium is found in rocks and in the earth’s crust with a concentration of 0.2 g / m3.
Deuterium is extracted from sea water
The wide availability of reagents and the large energy produced by the fusion reactions mean that this kind of energy is considered practically unlimited.
