In January 2022, the JET fusion experiment produced more power over a longer period of time than any past attempt. Two physicists explain the engineering advancements that made the result possible.
Fusion seems nearer than ever - but it won’t be the silver bullet to stop climate change.
Nuclear fusion is what generates the energy of the sun: scientists are getting closer to controlling a sustained fusion reaction on Earth.
Plus, the social pressure some people feel to be happy in the world’s happiest countries. Listen to The Conversation Weekly.
Fusion could create more energy than any other process that could be produced on Earth.
Fusion produces more energy per gram of fuel than any other process that could be achieved on Earth.

Despite recent reports, nuclear fusion-powered energy isn’t mere years from solving our clean energy needs. But physicists are making encouraging strides nonetheless.
The coils winding facility building in France, where a global effort to build the ITER fusion energy reactor is underway.
As fusion becomes more technically viable, it’s time to assess whether it’s worth the money because breakthroughs in the lab don’t guarantee success in the marketplace.
The superheated plasma inside the fusion reactor is twisted by magnetic fields.

Fusion power, if it works, offers vast amounts of clean energy and almost zero carbon emissions. A new experimental fusion reactor has come online, and it uses a curious twisted stellarator design.
The Joint European Torus (seen here with a superimposed image of a plasma) is one of the machines helping to unlock fusion power.
Why don’t we have nuclear fusion power yet? Because it involves taming plasmas at temperatures far hotter than the Sun’s core. But the good news is that physicists are slowly but surely figuring out how.
