Nuclear fusion may be closer to commercialization than previously thought, with private firms targeting operational reactors in the early 2030s. Major technical and economic hurdles remain, including ...

Engineers at the UK’s STEP (Spherical Tokamak for Energy Production) program have successfully tested a “plug-and-socket” magnet technology. This breakthrough is expected to dramatically lower the ...

Engineers in the United Kingdom are racing to build metal shields that can survive conditions similar to the center of the Sun, a prerequisite if fusion power is ever going to move from experiment to ...

UK-based Pulsar Fusion announced it has successfully achieved first plasma in its Sunbird nuclear fusion rocket exhaust system. The demonstration, a world’s first for a rocket of this type, was ...

A private nuclear-fusion company has heated a plasma of hydrogen to 27 million degrees Fahrenheit (15 million degrees Celsius) in a new reactor for the first time — hotter than the core of the sun. UK ...

Fusion power has always been a bit of a contradiction. The fusion part is actually kind of easy — an undergrad recently built a simple fusion device in his bedroom, for example — but getting ...
