Commonwealth Fusion Systems marked a major milestone Tuesday morning, announcing the installation of a key component of its Sparc demonstration reactor. The new part is a 24-foot wide, 75-ton stainless steel circle that forms the foundation of the tokamak, the doughnut-shaped heart of a fusion reactor that CFS hopes will be the first of its […]
German startup wins accolade for its fusion reactor design
Proxima Fusion, a two-year-old, German nuclear fusion startup, has published plans for a working fusion power plant in a peer-reviewed journal, in what is being touted as a step-change in the race to generate limitless energy. Today’s nuclear fission reactors create radioactive waste, whereas nuclear fusion releases vast amounts of energy, with zero carbon emissions and […]
Zap Energy shows off its new fusion power prototype, Century
For fusion power aficionados, hitting “breakeven” is something of a Holy Grail: the point at which a fusion reaction produces more power than was required to ignite it. Only one scientific experiment, at the National Ignition Facility, has accomplished that feat, and it took over a decade of tweaking the system to achieve the monumental […]
Every fusion startup that has raised over $100M
Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that […]
Marvel Fusion lands $70M for laser-powered fusion bet
When it comes to fusion power, there are two basic approaches: One, create a small star here on Earth that’s held in place by powerful magnetic fields. Two, use intense lasers to make a succession of even smaller stars, but repeat the process several times per second. Moritz von der Linden likes his odds with […]
