Not just cold fusion. We are still working on creating hot fusion reactions that are controlled. That honestly makes sense. It’s kinda weird that we were able to theorize the uncontrolled reaction of fission, and then used that to create a mostly kinda stable controlled fission reactor.
Cold nuclear fusion. We were quite successful with the hot kind, uncontrolled.
