Commonwealth Fusion Systems faces a litany of challenges, from complex physics and difficult engineering to building a supply chain. But it’s also trying to solve one of the fusion industry’s biggest issues: getting people to drop using the word “nuclear” and its toxic associations.
There are two main ways to harness the power of atoms. Nuclear fission captures energy from splitting relatively large atoms. Fusion is the opposite, tapping the power created when smaller atoms are fused together.
