Fusion energy is what gives the stars their seemingly limitless power.
A single fusion reaction between deuterium (D) and tritium (T) releases 17.6 MeV of energy, which is an enormous amount when added up over time.
Deuterium can be extracted from seawater, and tritium can be self-multiplied, giving it geopolitical advantages of securing fuel domestically. Because no greenhouse gas is contained in the fuel or exhaust, it also contributes to a carbon-neutral society.
Since fusion energy does not produce high concentrations of radioactive waste, there is optimism for its development as a permanent next-generation energy source.
