Google is making a big bet on a power source that hasn’t yet been used successfully anywhere in the world: nuclear fusion.Every nuclear plant in the world today is powered by fission reactions, which generate energy by splitting the nucleus of an atom. Fusion, by contrast, works by combining two nuclei, similar to how the sun produces energy.A fusion reactor would be a breakthrough that could quickly boost electricity production at a time when the world needs much more of it for artificial-intelligence data centers and electric vehicles. Commonwealth is among the best-capitalized companies in fusion, which has gained significant momentum in the past couple of years after decades of being seen as a pie-in-the-sky technology. The companies involved in developing the technology are privately held start-ups, and there aren’t easy ways for retail investors to buy into the trend. Is Nuclear Fusion the way to clean energy ?
