The project, a collaboration between scientists at MIT and a private company, will take a radically different approach to other efforts to transform fusion from an expensive science experiment into a viable commercial energy source. The team intend to use a new class of high-temperature superconductors they predict will allow them to create the world’s first fusion reactor that produces more energy than needs to be put in to get the fusion reaction going.
Bob Mumgaard, CEO of the private company Commonwealth Fusion Systems, which has attracted $50 million in support of this effort from the Italian energy company Eni, said: “The aspiration is to have a working power plant in time to combat climate change. We think we have the science, speed and scale to put carbon-free fusion power on the grid in 15 years.”
Interestingly, there was no direct quote from any MIT scientists here who is working on the project. The article quoted MIT's vice-president for research, but she's not working on this project.
So essentially, it appears that no one from MIT is making this claim, but everyone else on the peripheral is.
Let's mark this and check back in 15 years. Still, I will not be holding my breath.
