Radical Plan to Make Earth’s Deepest Hole Could Unleash Limitless Energy

Since its launch in 2020, a pioneering energy company called Quaise has attracted some serious attention for its audacious goal of diving further into Earth’s crust than anybody has dug before.   Following the closure of first round venture capital funding, the MIT spin-off has now raised a total of US$63 million: a respectable start … Read more

Nuclear fusion is one step closer with new AI breakthrough

The green energy revolution promised by nuclear fusion is now a step closer, thanks to the first successful use of a cutting-edge artificial intelligence system to shape the superheated hydrogen plasmas inside a fusion reactor. The successful trial indicates that the use of AI could be a breakthrough in the long-running search for electricity generated from nuclear fusion — bringing its … Read more

Why Isn’t Jupiter a Star?

The smallest known main-sequence star in the Milky Way galaxy is a real pixie of a thing. It’s called EBLM J0555-57Ab, a red dwarf 600 light-years away. With a mean radius of around 59,000 kilometers, it’s just a smidge bigger than Saturn. That makes it the tiniest known star to support hydrogen fusion in its core, … Read more

French nuclear regulator halts assembly of huge fusion reactor | Science

France’s nuclear regulator has ordered ITER, an international fusion energy project, to hold off on assembling its gigantic reactor until officials address safety concerns. This month, the ITER Organization was expecting to get the green light to begin to weld together the 11-meter-tall steel sections that make up the doughnut-shaped reactor, called a tokamak. But … Read more

‘Burning’ hydrogen plasma in the world’s largest laser sets fusion records

The secret behind a record-breaking nuclear fusion experiment that spit out 10 quadrillion watts of power in a split second has been revealed: a “self-heating” — or “burning” — plasma of neutron-heavy hydrogen inside the fuel capsule used in the experiment, according to researchers.  Last year, scientists at the Lawrence Livermore National Laboratory in Northern California announced the record … Read more

Physics Breakthrough as AI Successfully Controls Plasma in Nuclear Fusion Experiment

Successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy, but we can only realize this incredible dream if we can master the complex physics taking place inside the reactor.   For decades, scientists have been taking incremental steps towards this goal, but many challenges remain. One of the … Read more

Fusion power: DeepMind uses AI to control plasma inside tokamak reactor

For the first time, artificial intelligence has been used to control the super-hot plasma inside a fusion reactor, offering a new way to increase stability and efficiency Technology 16 February 2022 By Matthew Sparkes Plasma inside the TCV fusion reactor in Switzerland Curdin Wüthrich/SPC/EPFL Fusion reactors promise cheap, abundant and relatively clean energy – if … Read more

Fusion experiment smashes record for generating energy, takes us a step closer to a new source of power

An experimental nuclear fusion project has set a world record in generating energy on Earth using the same kind of reactions that power the sun. In the new experiments, the Joint European Torus (JET) in Culham near Oxford, England, produced blazingly hot plasmas that released a record-setting 59 megajoules of energy — about the same … Read more

Nuclear fusion: Record-breaking experiment suggests we really could build artificial suns

The Joint European Torus has sustained a super-hot plasma for 5 seconds, producing 59 megajoules of energy and suggesting that larger experiments could produce more power than is put in Technology 9 February 2022 By Adam Vaughan A white hot river of heat winds around the bottom of a doughnut-shaped machine before the searing light … Read more

European fusion reactor sets record for sustained energy | Science

In experiments culminating the 40-year run of the Joint European Torus (JET), the world’s largest fusion reactor, researchers announced today they have smashed the record for producing controlled fusion energy. On 21 December 2021, the U.K.-based JET heated a gas of hydrogen isotopes to 150 million degrees Celsius and held it steady for 5 seconds while … Read more
