Nuclear Fusion
-
A UK company with lofty aspirations around sustainable space travel has test-fired a rocket engine powered in part by plastic waste. Pulsar Fusion's ambitious plans also involve the development of nuclear fusion technology for high-speed propulsion.
-
A popular design in the pursuit of fusion power is the tokamak and an exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where a new record for maintaining super-hot plasma has reportedly been set.
-
Washington startup Helion Energy says its seventh-gen Polaris prototype will be the world's first fusion generator to demonstrate net electricity production, as early as 2024, and it's roped in a record-breaking funding round to get it built and running.
-
The US NRL is developing an Argon Fluoride laser that may one day make fusion power a practical by delivering the incredible temperatures required for a self-sustaining fusion reaction, with enough efficiency to make the process worthwhile.
-
MIT scientists have demonstrated how some of the biggest advances in nuclear fusion might come via projects that are smaller in stature, with the team revealing a record-setting superconductive magnet set for testing in a compact reactor in 2025.
-
Physicists have confirmed a major advance in the performance of the Wendelstein 7-X fusion reactor, with efforts to address inherent energy losses in the design potentially enabling the reactor to host plasma twice as hot as the Sun's core.
-
"Extraordinary results" from experiments with an extraordinarily high-powered laser have just taken us a whole lot closer to the goal of fusion ignition, where the energy generated through nuclear fusion is enough to trigger a runaway effect.
-
Chinese state media is reporting that scientists working on the EAST experimental nuclear fusion reactor have achieved a new world record by holding plasma of 120 million degrees Celsius for 101 seconds in their latest round of experiments.
-
For nearly a century, scientists have been tantalized by the prospect of attaining an inexhaustible source of energy through nuclear fusion. Achieving this goal is not so easy, as it turns out, but that doesn't mean exciting advances aren't being made.
-
Scientists have made a breakthrough in the way we study this plasma, managing to trap an ultracold form of it in a magnetic "bottle" for the first time, an achievement that could act as a springboard for research into nuclear fusion energy.
-
Now is the time, says a new report commissioned by the US Dept of Energy, for "urgent" government and private sector investment in a pilot fusion power plant on US soil by 2040. The report also lays out the key technical challenges that need solving.
-
In a promising development for tokamak-based nuclear fusion technology, the Korea Superconducting Tokamak Advanced Research (KSTAR) fusion device has set a world record by maintaining plasma at over 100 million °C for 20 seconds.
