This could be huge if fusion stops being a lab project and becomes grid power, and Commonwealth Fusion Systems, a Cambridge, Massachusetts fusion energy company, is building the machine meant to prove it. A win here means utilities and heavy industry could buy clean, round-the-clock power from far smaller machines. A $1.0B round from Temasek and Khosla Ventures, with 123 open roles, 56 added in 30 days, shows the build is accelerating.
