UK's JET Laboratory Sets New World Record for Nuclear Fusion Energy

The final experiment at JET marks a significant step towards commercial fusion energy, with plans for the world's first fusion power plant underway.

A new world record for energy generated by nuclear fusion has been set at the UK-based JET laboratory, achieving 69 megajoules of energy over five seconds.
The UK plans to build the world's first fusion power plant in Nottinghamshire, aiming for operations to begin in the 2040s.
JET's final experiment marks a significant milestone after more than 40 years of fusion research, bringing the world one step closer to commercial fusion energy.
The European successor to JET, ITER, faces delays and cost overruns, with full-scale experiments not expected until at least 2035.
Despite the record, JET did not produce more energy than was put into it, highlighting the challenges still facing commercial fusion energy.
