What you really need to know about that fusion news


The Commonwealth is working on a compact, relatively inexpensive reactor that will cost hundreds of millions of dollars, rather than billions of dollars, to build the NIF. Its approach relies on superconducting materials to achieve super-strong magnetic fields that can hold plasmas in place for fusion reactions (temperatures too high to use conventional materials to keep fuel in place). ).

Some fusion experts say actual reactors that could be used to generate significant amounts of electricity are still decades away. But the Commonwealth and other startups have more ambitious timelines, planning to build rallies within a few years and power plants in about a decade. Last year, the Commonwealth announced that it had raised $1.8 billion in venture capital to make that happen.

The NIF news will probably be a big boon for the fusion sector in general, attracting more interest and investment. But it does not guarantee that inertial confinement, or any other approach to consolidation, will be commercially successful. Achieving net gains in one type of reactor does not necessarily translate to other reactor types, so tokamaks and other reactors will need their own breakout moment on the path towards creating fusion energy.

For more details on the news, including how much power it takes to actually run those lasers, see My story. I also want to introduce this insurance from the Atlantic, delving into the history of fusion hype. And for the way forward for Commonwealth and other private consolidation efforts, read James’s in-depth features from February.
