22 févr. 2024 · Nuclear fusion, the process that powers the Sun and stars, merges two atomic nuclei into a larger one. Globally, government labs and companies are racing to generate power from fusion. Now China has joined the nuclear fusion race, with an estimated $1.5 billion budget, according to reports.
16 févr. 2023 · The success at this federal lab proves what fusion pioneers have long believed is possible: the same process that powers the sun can be recreated on Earth. That’s a huge step forward for the decades-long global mission of fusion scientists, providing humanity with a cheap, limitless and carbon-free source of electricity.
19 janv. 2023 · It takes about 300-ish megajoules off the grid to run the laser, this facility was not built to be a power plant, it was built to be a scientific facility but the demonstration of the self-sustaining fusion reaction is a really big deal and demonstrates for the first time the fundamental building block of what a fusion energy system could look ...
19 avr. 2024 · Nuclear fusion has the potential to provide limitless, carbon-free energy by mimicking the phenomenon that powers stars. However, there are still many challenges to overcome before the technology is commercially viable.
14 mai 2019 · The achievement by China’s Institute of Plasma Physics at its Experimental Advanced Superconducting Tokamak (EAST) is a milestone on the fusion journey, and will provide valuable insights for the International Thermonuclear Experimental Reactor (ITER) project, a collaboration between the European Union, India, Japan, China, Russia, South Korea and the United States.
22 déc. 2022 · Fusion ignition is the term for a fusion reaction that becomes self-sustaining, in which the reaction creates more energy than it uses up. Up until now, scientists were only able to break even. The National Ignition Facility used a special setup called inertial confinement fusion that involves bombarding a tiny pellet of hydrogen plasma with lasers to achieve fusion ignition.
13 juin 2023 · Researchers tried to counter the biggest problem in fusion research at the time – the “drift” (when plasma is isolated from an electric conductor) – by a specific arrangement of the magnetic tube resulting in a twisted magnetic field, forcing the particles in the plasma to alternate between the inside and outside of the tube.
11 déc. 2020 · The science of fusion is proven and the technical challenges of implementing practical, controlled, reliable and cost-effective fusion energy are being addressed through many experimental programmes. There are government-funded fusion research centres in 26 countries, including the USA, UK, Germany, China, Korea and Japan.
25 juin 2021 · Unlike conventional fission nuclear power plants, fusion produces virtually no harmful waste and emits zero carbon dioxide. A fusion reaction creates helium gas. It’s also renewable - the fuel sources, deuterium and tritium, are derived from hydrogen and can be extracted from seawater.
8 sept. 2015 · Different approaches to fusion energy are being pursued – from cold fusion, which still lacks evidence and may never work, to inertial fusion, which could work, to magnetic fusion, which really does work. The magnetic fusion approach uses strong magnetic fields to pressurize and trap the hot plasma fuel.
