The fusion energy industry's funding boom is showing signs of divisions within the ranks of founders and investors, with some expressing concern about when should fusion startups go public and whether their side businesses become a distraction. In the last four months, TAE Technologies and General Fusion have announced plans to merge with publicly traded companies, potentially receiving hundreds of millions of dollars to keep their R&D efforts alive. However, some investors are concerned that these companies have not achieved crucial milestones such as scientific breakeven, a milestone that indicates a reactor design that has power plant potential. Some believe startups should first reach this milestone in which a reactor generates more energy than it needs to ignite, rather than the need for a working power plant. Some argue that while others worry that the focus should be on the fusion industry, others worry about the focus on revenue rather than focusing on the power plant itself.
