FAQ

What is the Westinghouse Atom Smasher and why does it matter?

The Westinghouse Atom Smasher is the world's first industrial Van de Graaff particle accelerator, built in 1937. Early researchers at the site studied fundamental particle behaviors, laying technical groundwork for practical nuclear power, medical X-rays, and radar systems. Preserving it keeps historical engineering achievements visible to current developers solving today's manufacturing challenges.

How much did CFS raise and what is it for?

CFS raised $1.8 billion, its largest funding round since 2021. Combined with the $863 million raised last year, the company has now raised a total of $4 billion. The funds will accelerate progress toward commercialization of its SPARC fusion demonstration machine and development of ARC, the world's first grid-scale fusion power plant, at Fall Line Fusion Power Station in Chesterfield County, Virginia.

When will K2 Space launch its Giga-class satellite?

K2 Space plans to introduce its 100kW Giga-class satellite in the second half of 2028. The company's next mission, Trinity, will launch multiple satellites in Q2 2027.
