Question

When does continuous ignition automatically operate?

Answer 1

Continuous ignition operates when a fusion reaction produces enough energy to be self-sustaining after external energy input is cut off. Ignition and commercial plants for fusion energy are still in progress, but break-even, where fusion power equals heating power, is close.

Step-by-step explanation:

Continuous ignition automatically operates when a fusion reaction produces enough energy to be self-sustaining after external energy input is cut off. This occurs when factors like temperature, density, and time complement each other sufficiently. However, achieving ignition and commercial plants in the context of fusion energy is still a work in progress and has not been achieved yet. Break-even, a milestone where fusion power equals the heating power input, is close to being reached, providing hope for the future.
