Fusion energy gain factor, Q
The ratio of the energy produced by thermonuclear fusion to the energy required for heating the plasma to fusion temperature. If Q is less than 1, the fusion releases less energy than is required to ignite it. At Q = 1, scientific breakeven occurs. This is an important milestone in fusion research, but for an electricity producing fusion power plant, Q needs to be much higher. At Q > 5, the condition is referred to as ignition. Fusion generates as much energy as is needed to sustain it, and thus burns itself out like a fire in a fireplace. All the excess energy it produces can be used, for example, to generate electricity. Scientific breakeven was surpassed in December 2022, when the laser-driven inertial confinement facility NIF reached Q = 1.5.
ABOUT US
Energy encyclopedia (EE) is the project of Simopt. We have devoted ourselves to popularizing energetics in an educational and entertaining way since 1991. In the following years, we plan to continue the development of EE.
