Deep under the Nevada desert in the 1980s, the US conducted secret nuclear weapons research, including experiments to spark nuclear fusion reactions. These experiments led to the construction of the National Ignition Facility (NIF) in California, where researchers recently achieved a breakthrough in controlled fusion experiments.
The breakthrough at NIF, however, took longer than expected due to the limitations of the laser technology used. This prompted two young graduate students, Conner Galloway and Alexander Valys, to found Xcimer, a fusion firm based in Denver. They plan to experiment with more powerful lasers to build a working fusion reactor that can supply electricity to the power grid.
While Xcimer joins other organizations worldwide in the quest for fusion energy, there are significant engineering challenges to overcome. Extracting heat generated during fusion and managing high-energy particles are just a few of the hurdles. Despite these challenges, Xcimer remains confident in their approach, using molten salt to absorb heat and protect the reactor.
To fund their work, Xcimer has raised $100 million and plans to have a working reactor plugged into the electricity grid by the mid-2030s. The prospect of cheap, carbon-free electricity is driving their efforts, with the founders believing it will change the trajectory of humanity’s progress.
As the race for fusion energy continues, Xcimer’s innovative approach and determination to overcome challenges make them a key player in the future of clean, sustainable energy.
