Maintaining stability in a reaction this intense is notoriously tricky. Scientists achieve record-shattering results after ...

Unlike conventional chemical rockets, Sunbird relies on nuclear fusion – a process that replicates the energy production at the core of stars – to propel spacecraft.

“The articles in this issue [of JPP] represent an important step towards a fusion reactor based on the stellarator concept. Thanks to decades of experiments and theoretical research, much of the ...

Experts warn that the development of new energy sources, like advanced nuclear reactors and cold fusion, could be facing delays as a result of budget cuts and defunding efforts in the federal ...

Oswalt learned the science behind creating nuclear fusion. Now the next part was assembling a reactor. He sought financial help from his parents to build one. “I rebuilt the vacuum chamber ...

A commercial fusion reactor is expected to need tonnes of the element every day. “However, these challenges pale in comparison to the bigger challenges with plasma reactors and laser ignition ...

Nuclear fusion reactors, if and when they become practical, will need a steady supply of fuel. The source of that fuel is the uncommon lithium isotope lithium-6. And the established process to ...

The Sun, like other stars, is a natural fusion reactor, where stellar nucleosynthesis transforms lighter elements into heavier elements with the release of energy ...

U.K. start-up Pulsar Fusion has unveiled plans to build a fleet of reusable nuclear fusion-powered rockets, known as Sunbirds, that could cut journey times across the solar system in half.

A few minutes later, data from inside a new fusion test reactor pours into several computer terminals. “Every time we do this, we learn a little bit more,” says Mike Donaldson, senior vice ...
