What you really need to know about this new merger

Commonwealth is working on a compact, relatively inexpensive reactor that would cost hundreds of millions of dollars, instead of the billions it took to build the NIF. His approach relies on superconducting materials to achieve super-strong magnetic fields that can hold plasma in place for fusion reactions (temperatures are far too high to use conventional materials to hold fuel in place).

Some fusion experts say practical reactors that can be used to generate significant amounts of energy are still decades away. But Commonwealth and other startups have more ambitious timelines in mind, planning to build demonstrations within a few years and power plants within a decade or so. Commonwealth announced last year that it had raised $1.8 billion in venture capital to make it happen.

The NIF news is likely to be a big boon for the fusion field in general, sparking more interest and investment. But that’s no guarantee that inertial confinement, or any other approach to fusion, will be commercially successful. Achieving a net gain in one type of reactor does not necessarily translate to others, so tokamaks and other reactors will need to have their own watershed moment on the path to achieving fusion power.

I would also recommend this coverage from The Atlantic, which dives deeper into the history of the merger hype. And to find out what the way forward looks like for the Commonwealth and other private merger efforts, read James’ in-depth article from February.
