Nuclear fusion startups have attracted billions of dollars in funding.
The promise of fusion power has attracted high-profile supporters such as Bill Gates and Jeff Bezos.
While no startup has achieved net power production yet, many believe fusion power will be commercially viable in the 2030s.
The challenge lies in overcoming the technical hurdles associated with creating and containing the extremely hot plasma required for fusion reactions.
Different startups are pursuing different methods of fusion, including field confinement, inertial confinement, and a hybrid approach.
