Fusion ignition is when the fusion reaction becomes self-sustaining, generating more energy than is required to initiate and maintain the reaction. It is a critical milestone in developing nuclear fusion as a potential source of clean, safe, and abundant energy.

This article explores the key takeaways, understanding, challenges, and potential benefits of achieving fusion ignition.

Key takeaways:

1. Fusion ignition is when a fusion reaction becomes self-sustaining, generating more energy than is required to initiate and maintain the reaction.
2. Achieving fusion ignition is a critical milestone in developing nuclear fusion as a potential source of clean, safe, and abundant energy.
3. There are several approaches to achieving fusion ignition, each with its own advantages and challenges.

Understanding Fusion Ignition:

Fusion ignition uses heat and pressure to force atomic nuclei together, causing them to fuse and release energy in the form of light and heat.

To achieve fusion ignition, a high temperature and pressure level must be sustained for a sufficient period to overcome the repulsive forces between atomic nuclei.
