Magnetic Confinement Fusion

The U.S. leads the world in fusion energy research. It can't squander that lead like it did with microchips

Two types of fusion reactor called tokamaks and stellarators both have drawbacks – but a new design combining parts from both could offer the best of both worlds

This development aims to achieve a remarkable milestone, operating the nuclear fusion reactor for 300 seconds at 100 million degrees by the year 2026.

The breakthrough marks the second time that the core of a fusion reactor has given out more energy than it has taken in, but significant challenges remain

After successful recommissioning in autumn 2022, the Greifswald nuclear fusion experiment has surpassed an important target. In 2023, an energy turnover of 1 gigajoule was targeted. Now the researchers have even achieved 1.3 gigajoules and a new record for discharge time on Wendelstein 7-X: the hot plasma could be maintained for eight minutes.

Unlike the nuclear power of today, sparked through a process called fission, nuclear fusion wouldn't create long-lived radioactive waste.

The fusion breakthrough that the US Energy Department announced this week is scientifically significant, but the significance relates to the monitoring of the country's nuclear weapons stockpike, not to clean electricity generation.

Researchers at the US National Ignition Facility created a reaction that made more energy than they put in.

U.S. officials on Tuesday formally announced that government scientists at Lawrence Livermore National Laboratory's National Ignition Facility had for the first time created a nuclear fusion reaction that produced more energy that it had consumed. Nuclear fusion is often called the "holy grail" of clean energy. This fusion ignition is "one of the most impressive scientific feats of the 21st century," Energy…

On Tuesday, scientists at Lawrence Livermore National Laboratory announced that they had achieved nuclear fusion "ignition," but truly limitless energy is still a ways off.

Our society faces the grand challenge of providing sustainable, secure and affordable means of generating energy, while trying to reduce carbon dioxide emissions to net zero around 2050.

The Big Friendly Gun can produce nuclear fusion without the need for lasers and strong magnets.

In 1974 I called a nuclear engineer to interview him for a term paper on nuclear fusion power. We talked about all the advantages of fusion power, its prospects for the future, the impact on civilization, and so forth…and at the end of the interview, I asked him when he expected to see commercial fusion power. "I think it will be about 20 or 25 years from now that we see the first fusion reactor come online." And…

Scientists at a laboratory in England have shattered the record for the amount of energy produced during a controlled, sustained fusion reaction. The production of 59 megajoules of energy over five seconds at the Joint European Torus—or JET—experiment in England has been called "a breakthrough" by some news outlets and caused quite a lot of excitement among physicists. But a common line regarding fusion electricity…
