Jeff Bezos-Backed Company General Fusion To Build Nuclear Fusion Facility In UK (businessinsider.com) 138

Last Thursday, a Canadian company backed by Jeff Bezos, called General Fusion, announced it's building a nuclear fusion facility in the UK. Insider reports: General Fusion and the UK Atomic Energy Authority (UKAEA) announced the project together, which will see General Fusion build a fusion demonstration plant in the village of Culham, near Oxford. The facility will be a proof-of-concept, allowing General Fusion to demonstrate its Magnetized Target Fusion (MTF) technology before going on to build its first commercial facility. According to General Fusion, construction will begin in 2022, and it is expected to be about three years before the plant is able to open.

"This new plant by General Fusion is a huge boost for our plans to develop a fusion industry in the UK, and I'm thrilled that Culham will be home to such a cutting-edge and potentially transformative project," the UK science minister, Amanda Solloway, said in a statement. The BBC reports Bezos has been an investor in General Fusion for over a decade, and the company raised $100 million in its latest funding round.

    For the last forty years I've been hearing that fusion-based power is only thirty years away. Is it possible that it's likely that these predictions are finally going to be wrong?

    • There really doesn't seem to have been much of a rush. ITER is an insanely slow project. It was started 15 years ago and they might have a reactor working in another 5 years. Perhaps being run by a business there's going to be a desire for some ROI.
    • The main problem, according an article by a nuclear engineer I read years ago, is small funding.

      According him, the predictions about how much time it'll take to get fusion working are all based on a single metric: the current state of knowledge and how much it needs to advance, assuming proper funding to do that advancement.

      Engineers calculated it'd take, if I remember right, about $50 to $100 billion USD to get there, at the full rate of potential technological development -- in early 2000's USD values min

        Not true. It is a factor, yes, but there are other limiters. For example, the Wendelstein X-7 Stellarator was basically build only after computers were powerful enough to allow the design. Factor all things in and that meant completion in 2015. Yes, things take long. But the X-7 is a plasma and materials research installation, still, say, at least 2 generations removed from a working experimental power station. That gives a time-frame with perfect funding of something like 50 years to that working experimental power station and 25 years or so more to the first non-experimental power station. This is a lower estimate and actual numbers may be 100 or 150 years to that working non-experimental power station. Still, the goal looks quite reachable and the payoff will be significant, so it is worthwhile research.

        People need to stop thinking that because crappy software can be written in a year or two, things go as fast in other areas. Most engineering stuff takes a lot of time. Incidentally, software written to proper engineering standards does too. I would claim that we can mostly still not do that even today. Slapping together something insecure, inefficient, unreliable and generally crappy can be done a lot faster and even when you do not really understand what you are doing.

          Fusion is problem with many avenues of advancement where sufficient advances in any one area can significantly impact overall viability. This is why I believe with sufficient investment there can be more advancements akin to discovery of h-mode that eventually push the technology far enough into the realm of viability. At that point it is a safe bet there will be a ramp up of interest and funding including great power competition as viability approaches certainty.

          Another point is that all these projects benefit from each other. Whether a stellarator, tokamak, hybrid or none of the above they all contribute to understanding and exploitation of plasma dynamics (NIF excluded) and associated R&D superconductors, magnet design, materials, diverters..etc which benefits and influences advancement of all fusion projects. The efforts (cash) push technology and create markets for further R&D into a large number of supporting industries.

          ITER by itself placed a large enough order of niobium superconductors to significantly ramp up global production capacity.

          The 7-X was designed for research within a specific budget. It was never designed to push technology as fast as possible at a higher cost. To cite one projects timeline as an excuse to take forever is not reasonable. It does take considerable time and effort to build things and there is always diminishing returns yet the world isn't even trying to take Fusion seriously. More money means faster iteration, more risk taking, parallel experiments and funding development of necessary advancements in supporting technology.

        • "crappy software can be written in a year or two": Some of us take much longer than that.

      Bezos founded a rocket company for over twenty years ago, which has still failed to reach orbit.
      So Bezos funding this Canadian company does not fill me with confidence.

    • For commercial purposes, all fusion power requires fission: it's the only viable source of the tritium for deuterium/tritium fusion. If you've done the work to build that many fission plants to provide the fuel, why waste the effort on an unproven technology?

      Thorium fusion would make much more sense, but it's not found in so many old science fiction stories, and is nowhere near as romantic.

        Thorium fusion would make much more sense

        I can't tell if this is meant to be tongue in cheek, or if you meant fission instead of fusion. Building up nuclei heavier than iron is not energetically favorable [wikipedia.org].

      • For commercial purposes, all fusion power requires fission: it's the only viable source of the tritium for deuterium/tritium fusion.

        Right now, fission barely creates enough tritium to supply glow-in-the-dark watch faces and refills for aging warhead triggers.

        The idea for D-T fusion reactors is to use the huge neutron flux from that reaction to breed tritium from lithium surrounding the fusion reactor. Managing that is undoubtedly going to be a problem at least as hard as maintaining the fusion reaction itself.

    • When something has never been done before, it's a mistake to take guesses about how long it will take too seriously.

      So yeah it's a huge financial risk, with almost unimaginable potential reward. Almost certainly it is possible and will be done eventually, but maybe not in our lifetimes especially if other tech meets near-term needs more cheaply which is a distinct possibility.

    General Fusion

    So Mister Fusion is a General now?

  • General CONFusion.
  • A friend of mine works there.

    The idea is that you magnetically inject plasma into a core, where hyper-synchronized pneumatic cylinders compress the plasma into fusion, pulsing maybe once a second. The heat is taken away by the surrounding protecting liquid metal into a heat exchanger.

  • Keep chasing the improbable dream while real-world alternative exist.
    • by gweihir ( 88907 ) on Tuesday June 22, 2021 @09:04AM (#61509688)

      It is not actually improbable. It just has a realistic time-frame of another 100 years or so until it becomes relevant for energy generation. As the general public does not understand such time-frames, this becomes "30 years" in the press.

      • "The future" has been defined as 30 years away at least as far back as 1985. It's already been proven in cinema form that mankind is really terrible at looking even that far away with any realistic prediction whatsoever.

      Yeah the Brexit disaster where the UK economy is growing quickly whilst Europe is in the shitter.

  • Seeing how much electricity we sell here and abroad ( US ) it's a bit odd to me that Hydro Quebec would not have been first on the list for that one.
    that neither the USA or Canada would get the " first " actual working unit up and running just tells me that the tech must be faulty and/or needs way more development before serious clients consider it. Matter of costs/kWh ? Cheaper sources available without the hassle ? Let's see the results of that first installation

    • by gweihir ( 88907 )

      No need to be skeptical. This is a highly experimental research station. May work, may not work, will not work as power station.

    • What's odd is business investment at all. This is going to be pure research for probably a long time. Anyone taking investor money at this stage is little better than a snake oil salesman.

    • by ceoyoyo ( 59147 )

      Why would Hydro Quebec be interested? They've got more hydroelectric resources than they can exploit, and the existing dams produce lots of excess to sell to the US.

      The UK has offshore wind, but other than that they're dependent on gas and oil that is both awkward to get and isn't going to last forever.

    • by grub ( 11606 )
      Hydro Quebec is mainly hydroelectricity. I'm more surprised that AECL is not involved, at least from what I've read. They were a prime partner in building the CANDU reactors.
  • There seems to be quite a number of press releases lately about various fusion projects/start ups. I can't help but think there is a lot of pressure on these groups to justify their funding and so they have gone the PR route to make it sound like they are making real progress when as far as I can tell it still is all incremental.

    A good point was brought up earlier that there is no natural fuel source for these designs which should be a red flag. I have also read elsewhere that they also have some of th
    • I think its a combination of:

      Lots of interest in and money for clean energy

      Lots of wealthy high tech companies with very smart people who are badly Dunning-Kruger'd on fusion. Many don't understand just how much is known about fusion, and that many of these schemes fail for well understood reasons (like Rayleigh-Taylor instability https://en.wikipedia.org/wiki/... [wikipedia.org] which is the death of most clever fusion ideas.

    • "Temperature" is a measurement of the average speed of particles.
      Here we have a plasma. And that plasma is basically a high vacuum.
      So you have a big chamber, which is really a vacuum, and have a finger hut full of deuterium/tritium (not sure what ITER is using) compressed and heated by a magnetic field. Some yards away from the walls.
      While the "temperature" is a million C, you could put your hand into the fusion reaction and feel nearly nothing. The neutron flux would be a different matter ...

  • I'll get excited when someone builds a reactor that might reach break-even when you don't count the worse-than-useless neutrons, which are 80% of D-T yield.

  • Light element fusion produces neutrons, which cannot be confined using magnetic field because they have no electric charge. Hence a fusion reactor must deal with a flux of run away high energy neutrons hammering the device, and that tricky solutions must be found to deal with them.

    The holy grail of fusion is Hydrogen+Boron, which does not produce neutrons, but we are not yet there.
