The old joke about fusion energy is that it's 20 years away and always will be. That might be changing. Here's how @CFS_energy, a startup that aims to commercialize fusion, came up with a breakthrough technology. More on Bloomberg Primer trib.al/FyCDbYU

Mechazilla has caught the Super Heavy booster!

What’s CFS been up to in the last six months? Picking a location for our first fusion power plant, ARC, and making magnets for our net fusion energy demonstration machine, SPARC. Check the twice-yearly update video from CEO @Bobmumgaard for the details — and a sneak peek at some new fusion hardware on the way. #FusionEnergy


Our CEO, Bob Mumgaard, had the opportunity this month to speak about fusion and our deeply human connection to it at @EmCollective Demo Day. His talk is a great primer in fusion — to understand how it works, and why it’s the last energy source we’ll ever need. #FusionEnergy #PowerMoves #ECDemoDay

Insane. SpaceX caught a Starship

No, we didn’t lure a UFO into CFS headquarters. This photo actually shows our first D-shaped toroidal field (TF) magnet in the making, nestled inside a cryostat that cools it down for testing. And of course some of the hundreds of people it took to design, engineer, and build it all. Stay tuned for test results as we build our first fusion energy machine, SPARC.




Meticulous #manufacturing is key to making SPARC, the tokamak we’re building to produce fusion energy. Check how our partner @WalterTostoSpa crafted the inner shell of the vacuum vessel at SPARC’s heart. It’ll house a superheated plasma that generates #fusion power.

Unbelievable plenary from Darby Dunn @RocketJoy @CFS_energy about the scale up of fusion power plant magnets at the Applied Superconductivity Conference. 270 km of HTS wire in one coil 🤯
