A recent physics breakthrough that could serve as a proof-of-concept for the development of nuclear fusion reactors capable of producing near-unlimited energy has finally passed its official peer-review successfully.
On Dec. 5, 2022, a team of researchers at the U. S. National Ignition Facility (NIF) in California recorded data indicating that they’d achieved a nuclear fusion reaction that created more energy than it took to produce. The reported results were the first of their kind.
In physics this is sometimes colloquially referred to as a “free lunch,” meaning that we could one day scale a nuclear fusion reactor to the point where it was capable of producing near-unlimited energy.
If the NIF team’s reported results were correct, their breakthrough research could serve as a platform for the future technology that might help us eliminate our dependence on carbon energy and supercharge fields where energy scarcity presents as a roadblock, such as artificial intelligence and quantum computing.
But, as Carl Sagan put it, “extraordinary claims require extraordinary evidence.” News of the breakthrough was taken with both a measure of optimism and a grain of salt by the physics community. The general consensus, at the time, was that we’d all need to wait until peer-review before anyone shouted “eureka!” at the findings.
Eureka time?
The peer-review is in and, according to a report in the APA Physics journal, multiple teams have confirmed and replicated the results.
Recreating the experiment was no easy feat. To achieve the original fusion reaction, NIF scientists used a technique called inertial confinement fusion. This form of fusion involves bombarding heavy hydrogen atoms with nearly 200 lasers causing them to superheat and, ultimately, fuse at pressures greater than those found within the sun.
While this early work has only just been confirmed through peer review, the NIF device could serve as a platform by which practical fusion reactors can be built. It’s currently too soon to predict when a viable fusion reactor might be achieved.
Next generation energy
Once realized, however, the free availability of so-called next generation energy sources could supercharge the engineering and development of adjacent technologies such as artificial intelligence and quantum computing.
Fields such as those, where energy bottlenecks play are perceived to be the next great hurdle to scale, could see generational leaps in progress once those roadblocks are removed.
As Cointelegraph recently reported, OpenAI CEO Sam Altman says there’s no way to build the AI systems of the future until there’s a fusion energy breakthrough. It's possible that this work from the NIF team could be the first confirmed steps toward that breakthrough technology.
OpenAI might be in the best position to understand the energy requirements needed to train systems such as ChatGPT, but it bears mention that Altman is personally invested in a private company that’s working on fusion.
