Reaction must have a net energy gain

For information on https://en.wikipedia.org/wiki/Nuclear_fusion

There are multiple initiatives pursuing nuclear fusion, please post in the comments if you find interesting ones that I haven't listed:

1. ITER: International collaboration to demonstrate fusion feasibility using the world's largest tokamak for magnetic confinement.

2. NIF: US-based facility employing inertial confinement fusion with powerful lasers to achieve ignition and energy gain.

3. JET: European tokamak research facility, contributing to ITER's development and exploring plasma physics and fusion technology.

4. W7-X: German stellarator aiming to demonstrate the feasibility of its complex magnetic field configuration for fusion power generation.

5. Private Companies: Start-ups such as TAE Technologies, Helion Energy, First Light Fusion, and Commonwealth Fusion Systems.
