Interactive diagram showing energy flows in a fusion power plant. Adjust Q, conversion efficiency, and heating system efficiency to explore how plasma gain translates to net electricity.
While physicists chase energy gain, investors in fusion power are chasing the bottom line. A new way of evaluating economic viability suggests some are barking up the wrong tree
In the city of Everett, inside a vault built with thick concrete blocks is Polaris, a machine that could change the world.
Solving the grand challenge of alchemy
Breakthroughs from two rival experiments, Germany’s Wendelstein 7-X and the Joint European Torus, suggest the elusive dream of controlled nuclear fusion may be within reach
Longtime Slashdot readers smooth wombat and AmiMoJo shares a fusion energy breakthrough from China. Charming Science reports: China's "artificial sun," officially known as the Experimental Advanced Superconducting Tokamak (EAST), has achieved a groundbreaking milestone in fusion energy research. Ac...
US scientists made a breakthrough in fusion energy, discovering a new fuel mix that could improve efficiency and reduce tritium reliance.
Fast prototyping revives a 70-year-old reactor design
The ATLAS facility will use three ultra-high intensity lasers to initiate the same reaction that powers the Sun and stars.
“Every one of the stars in the sky uses fusion to generate enormous amounts of energy. Why shouldn’t we?”
The JET fusion reactor in the UK has set a new world record for energy output — but the promise of abundant, clean energy is still way off.
A sustained, stable experiment is the latest demonstration that nuclear fusion is moving from being a physics problem to an engineering one.
Despite repeated claims that the prospects for commercialization have never looked brighter, the stark reality is that practical fusion-based electric power remains a very distant prospect.
Even scientists who were skeptical of work at the National Ignition Facility called the results a success.
