Net energy gain from controlled nuclear fusion (Q>1) means the energy released by the fusion reaction exceeds the energy consumed to sustain the reaction, i.e., scientific energy breakeven; however, the 2022 National Ignition Facility result is only a gain from laser to fusion energy, and when full-system energy consumption is included, it remains very far from engineering feasibility.

UnverifiedIn December 2022, the National Ignition Facility at Lawrence Livermore National Laboratory in the United States achieved net energy gain from controlled nuclear fusion (Q>1) for the first time, with laser input of about 2.05 megajoules and fusion output of about 3.15 megajoules.73% similarUnverifiedIon thrusters separate the energy source from the reaction mass, with energy able to come from solar panels, batteries, or a nuclear reactor, whereas chemical rockets store energy within the propellant itself.71% similarUnverifiedNuclear fusion uses isotopes of hydrogen (deuterium and tritium) as fuel, and can theoretically provide near-limitless, clean, high-density energy without producing long-lived highly radioactive waste.67% similarUnverifiedNuclear fission produces long-lived radioactive waste and carries the risk of core meltdown, whereas nuclear fusion fuel reserves are nearly limitless and the reactor cannot run out of control and explode.64% similarUnverifiedNuclear fusion has yet to achieve truly net-energy-gain commercial power generation.64% similar
