Last week, the U.S. @departmentofenergy.bsky.social (DOE) established a new Office of Fusion — a good first step in bringing a new federal focus to this critical energy source. Now we need to ensure this office is set up for success with the leadership, the mission, and the resources it needs. 1/5

A one-time $10B injection of U.S. public capital into efforts and partnerships with the fusion industry would accelerate commercial deployment in the U.S… but how should the $10 billion be allocated? In a new one-pager, we break down key line items.⬇️

To get the first half of our vacuum vessel from Italy to the USA, we flew it on an Antonov An-124 Ruslan aircraft, an unusual 4-engine cargo plane with room for the 48-ton component. Unlike passenger planes, the nose of the An-124 hinges upward to load and unload cargo.
