The US National Ignition Facility has achieved even higher energy yields since breaking even for the first time in 2022, but a practical fusion reactor is still a long way off
Why will a tokamak never work, exactly? We’ve been running fusion experiments in them for 60 years and have a pretty good idea that we can make one big enough to produce power. We’re just baby stepping through the work so we don’t build a $30 billion dollar power plant that’s missing a design element.
K-DEMO, JT-60, DEMO, CFETR, STEP, and the US DoE’s planned reactor suggest a high level of confidence that the science is already there. It’s just an engineering problem, much like the nuclear bomb in 1935.
