A new twist on fusion power could help bring limitless clean energy

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.

Before fusion: a human history of fire

Fire has played a vital role in human history, and will continue to. Recent advances in fusion herald the freeing of fire from captivity back into its natural form.

The risks attached to South Africa’s nuclear energy strategy

The nuclear deal South Africa signed with Russia is set to be massively expensive and comes with a fair amount of risks.

Nuclear fusion, the clean power that will take decades to master

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.

Don’t get too excited, no one has cracked nuclear fusion yet

Aerospace giant Lockheed Martin’s announcement this week that it could make small-scale nuclear fusion power a reality in the next decade has understandably generated excitement in the media. Physicists…

For decades a distant dream, the countdown to nuclear fusion may have finally begun

The latest results from the National Ignition Facility in the US represent the passing of a nuclear fusion power milestone and come after a year of significant progress at projects in France and the UK…
Nuclear power and nuclear weapons: what’s the difference? Patrik Hermansson

Debunking myths on nuclear power (it’s not for making bombs)

It is the received wisdom that nuclear weapons and nuclear power are inseparable. Consequently, any country that builds a civilian nuclear power station is able to build an atomic bomb within a couple…
