Investors are still betting on the 'Holy Grail' of nuclear fusion
A fusion startup backed by Jeff Bezos just raised another $65 million
General Fusion, a nuclear fusion based startup, is among a handful of fusion startups that have been backed by prominent venture capital funds, such as Bill Gates' Breakthrough Energy Ventures.
Fusion is a promising technology, but inventing a power plant that produces more energy than it uses is incredibly costly. But if successfully commercialized, fusion could provide a clean source of energy without many of the drawbacks of nuclear fission, like the production of hazardous waste.
Creating a commercial device that generates a net gain in energy will likely require tens of billions of dollars. That's one reason why many private investors have been reluctant to fund fusion startups.
Large government programs and governments themselves are beginning to either directly or indirectly in programs that seek to commercialize nuclear fusion.
ITER is an experimental fusion reactor facility under construction in Cadarache, South of France to prove the feasibility of nuclear fusion for future source of energy. In southern France, 35 nations* are collaborating to build the world's largest tokamak, a magnetic fusion device that has been designed to prove the feasibility of fusion as a large-scale and carbon-free source of energy based on the same principle that powers our Sun and stars. The experimental campaign that will be carried out at ITER is crucial to advancing fusion science and preparing the way for the fusion power plants of tomorrow.Learn more
Over the past several years, more than two dozen research groups—impressively staffed and well-funded startups, university programs, and corporate projects—have achieved eye-opening advances in controlled nuclear fusion. They’re building fusion reactors based on radically different designs that challenge the two mainstream approaches, which use either a huge, doughnut-shaped magnetic vessel called a tokamak or enormously powerful lasers.Learn more
