Nuclear Fusion Experiment Produces Net Energy for Extended Period
Scientists achieve sustained fusion reaction that generates more power than it consumes.
A major fusion research facility has achieved what many considered impossible: sustained net energy production from nuclear fusion.
## The Achievement
For 30 seconds, the reactor produced 20% more energy than was used to initiate and maintain the fusion reaction—a historic first.
## Why It Matters
Fusion promises virtually unlimited clean energy with minimal radioactive waste. This milestone proves the concept is scientifically viable.
## Technical Challenges Remain
Scaling up to commercial power plants will require maintaining fusion for much longer periods and developing materials that can withstand the extreme conditions.
## Timeline to Commercialization
Experts now believe commercial fusion power could be achievable within 15-20 years, significantly sooner than previous estimates.
