Experiments in 2020 and 2021 yielded the world's first burning plasmas, in which most of the plasma heating came from nuclear fusion reactions. [11] This result was followed on August 8, 2021 by the world's first ignited plasma, in which the fusion heating was sufficient to sustain the thermonuclear reaction.

That experiment briefly achieved what's known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to t US scientists repeat fusion ignition ...
Unlike nuclear fission — the process used in the world’s nuclear plants today, which is generated by the division of atoms — nuclear fusion leaves no legacy of long-lived radioactive waste.
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [1]
The U.S. Department of Energy officially announced a breakthrough in nuclear fusion on Tuesday that puts the world one step closer to harnessing an abundant energy source free from carbon ...
SPARC is designed to achieve this with margin in excess of breakeven and may be capable of achieving up to 140 MW of fusion power for 10 second bursts despite its relatively compact size. [ 2 ] [ 1 ] The project is scheduled to start operations in 2026, with the goal of demonstrating net power (Q > 1) in 2027. [ 4 ]
U.S. scientists have achieved “ignition” — a fusion reaction that produced more energy than it took to create — a critical milestone for nuclear fusion and a step forward in the pursuit of ...
