Commonwealth Fusion Systems

Commonwealth Fusion Systems is the world's largest and leading commercial fusion energy company. Fusion, the physical process that powers the sun, occurs when light atoms like hydrogen combine to form heavier atoms like helium. That releases tremendous amounts of energy. Fusion is hard to reproduce on Earth, but CFS machines use a design called a tokamak to do so. Fusion releases no carbon dioxide or other greenhouse gases. Because fusion is clean, reliable, and safe, with abundant fuel, it could be the last energy source humanity needs. -text from cfs.energy
