Billionaires Are Chasing The Holy Grail of Energy: Fusion (bloombergquint.com) 185

Posted by EditorDavid from the man-made-stars dept.
Long-time Slashdot reader Zorro shared this article from Bloomberg: Not long before he died, tech visionary Paul Allen traveled to the south of France for a personal tour of a 35-country quest to replicate the workings of the Sun. The goal is to one day produce clean, almost limitless energy by fusing atoms together rather than splitting them apart. The Microsoft Corp. co-founder said he wanted to view the early stages of the International Thermonuclear Experimental Reactor in Cadarache firsthand, to witness preparations "for the birth of a star on Earth." Allen wasn't just a bystander in the hunt for the holy grail of nuclear power. He was among a growing number of ultra-rich clean-energy advocates pouring money into startups that are rushing to produce the first commercially viable fusion reactor long before the $23 billion ITER program's mid-century forecast. Jeff Bezos, Bill Gates and Peter Thiel are just three of the billionaires chasing what the late physicist Stephen Hawking called humankind's most promising technology.

Scientists have long known that fusion has the potential to revolutionize the energy industry, but development costs have been too high for all but a handful of governments and investors. Recent advances in exotic materials, 3D printing, machine learning and data processing are all changing that. "It's the SpaceX moment for fusion," said Christofer Mowry, who runs the Bezos-backed General Fusion Inc. near Vancouver, Canada. He was referring to Elon Musk's reusable-rocket maker. "If you care about climate change you have to care about the timescale and not just the ultimate solution. Governments aren't working with the urgency needed."

The company Allen supported, TAE Technologies, stood alone when it was incorporated as Tri-Alpha Energy two decades ago. Now it has at least two dozen rivals, many funded by investors with a track record of disruption. As a result, there's been an explosion of discoveries that are driving the kind of competition needed for a transformational breakthrough, according to Mowry.
The article reports one fusion company founded last year by six MIT professors is "confident they'll be able to produce a prototype of a so-called net energy reactor by 2025."

    I lived in a grad student dorm at the University of Texas for my first two years in law school. The first year a grad student in physics gave a talk about the viability of nuclear fusion energy production. He said that about thirty years before then people optimistically predicted that it would be dominating energy production thirty years from then, but that the science had advanced fairly dramatically, and he thought within another thirty years or so we really would see it. By the way, that was in 1981. We have been hearing this about nuclear fusion since the 1950s. But *this* time it's different!

            There is a way in which a billionaire's money can be better than other money, in that if all the money is coming from a single individual, that usually translates into the major decisions being made by a single individual. Those decisions may be good or they may be bad, but at least you won't have half of the money/influence fighting against the other half and the project going nowhere as a result. And if the individual's decisions are mostly good, that means a lot of progress can be made in a relatively short period of time (see Tesla, SpaceX, Waymo, etc)

        So which of the three methods outlined in this 1976 clairvoyant report, from the which this magic graph was lifted, is the method that will provide us with practical fusion energy: is it the theta pinch, the mirror machine or the tokamak? Did you ever look at the actual report [pppl.gov]?

        As it happens there is well funded effort to build a tokamak, which should demonstrate break-even in about 20 years. It is called ITER, and is mentioned in the summary. Unlimited funding would reduce the schedule but is unlikely to cut it in half no matter how much money was provided, since lots of experimentation will be needed to work out the technical issues. The roughly 226 tokamaks that have been built (yes, a lot of work has been done, and amazingly the U.S. government is not the only source of funding for research in the world) have provided a lot of experience to work with but more work needs to be done as it scales up.

        The other two concepts in the document are dead as viable approaches at present.

        The report envisions that a total of $65 billion (current dollars) would be needed (pretty much regardless of funding schedule) to produce a demonstration fusion reactor, the actual US expenditure since that time has been about $30 billion, but of course a large chunk of that (about $10 billion) went into the dead-end NIF which failed.

        ITER expects to build that demonstration fusion reactor for a total cost of about $20 billion, and has a solid technical case to support it.

        But the report writers, making a pitch for extravagant funding, really had no idea what funding or schedule made sense because they were guessing about technical feasibility of any of the concepts.

        It is time to give this chart a decent rest.

        • Break-even was passed about a decade ago.

          The mini reactor that came out of MIT recently is the one to look at.

            No fusion system of any kind has reached breakeven yet, which is Q=1 (power being released by the fusion reactions is equal to the required heating power). This is what the term "breakeven" means, unless qualifications are added to make it mean something else (to define lower bars to clear, generally, as at NIF), And classic breakeven, Q=1, is what ITER will do. Currently the highest Q value was JET (Joint European Torus) with 0.67.

            The US provides about 9% of the funding for ITER, nowhere near half. That funding is subject to political infighting -- for example the US wanted the ITER prototype to be built in Japan, the rest of the consortium other than the US and Japan wanted it built in Cadarache in France. When the invasion of Iraq kicked off and France refused to support Bush's Excellent Arabian Adventure the US government shut down funding contributions to ITER and bailed from the consortium but rejoined later. Currently the US is in arrears with its payments to the ITER project.

            From Physics Today: "Since rejoining ITER in 2003, the US has never come close to providing annual contribution levels commensurate with its 9% ownership share. Through FY 2017, it has contributed a total of $1.1 billion. ITER spokesperson Laban Coblentz says the US made no cash contribution to support operations at the French site in FY 2016 or 2017, and the unpaid balance for the two years stands at $65 million. In addition, the US in-kind contribution in 2017 fell short by about $50 million. Five member nations - China, India, Japan, South Korea, and Russia - have the same ownership share as the US, and Coblentz says those countries are pulling their weight. As the host, the European Union is paying nearly half of ITER's cost."

            America's political instability with its whipsaw changes in government makes it a liability in long-term international scientific collaborations for this reason.

        • That report is positively ancient, and no one should look at particular approaches believed most promising 42 years ago. But it made a particular promise about research speed vs funding, and this promise turned out true. So the report is still valid to refute complaints that "fusion is always 30 years in the future".

          ITER isn't a demonstration fusion power reactor, it's a fusion testbed built to power-reactor scale in terms of dimensions and energies. It's expected to show energy returns of 10 to 1 (so-called Q factor) sustained for hundreds or thousands of seconds. Whether it succeeds or not in an unknown, in part that's why it's being built. One school of thought says going big simplifies things and makes sustainable plasma fusion easier, another more pessimistic school says going big reveals more problems. The "E" in ITER stands for "Experimental" after all.

          If ITER shows tokamak fusion is practical then comes DEMO, a fusion reactor that will produce electrical power. Once the bugs are shaken out of that hardware then comes PROTO, the first-generation commercial fusion generating plant. That's the current road-plan, whether it survives reality is another matter.

          ITER's "first light" should be in 2025 or so if all goes well. It probably won't though.

          Computer modeling has been a tremendous help, but we do not have the capability to simulate a working tokamak reactor yet. We don't even have a complete understanding of plasma physics, for example modeling disruptions and ELMs in reactors can't yet be done to the best of my knowledge. Simulation generally needs very complex monte carlo models that simulate chemistry and nuclear interactions, magnetohydrodynamics (electric-magnetic "fluids"), etc.

          Better magnets help shrink the size and may help reach new operational modes more easily, but this field is unbelievably slow. The current state of the art is Nb3Sn, and the material was discovered over 50 years ago. To get good magnets made from HT superconductors you're looking at a few more decades. This is one issue with the MIT arc design, the magnets required can't quite be made yet by the looks of it. Also the cables are tremendously expensive, Nb3Sn roughly $1k/m

          Better materials help, but the radiation coming from a nuclear fusion reactor cannot be simulated offline to help develop new materials. Think an order of magnitude more nuetron flux than fission, but also proton bombardment and helium bubbles forming. Using a spallation neutron source may get the neutron flux, but not the proton flux etc. Best way is to try out new materials in the reactor...

          We're nearing 100 years of trying to make fusion work, it's just the most difficult problem humanity has ever tried to solve.

    Then nobody is able to reproduce the results that the original team reported. Or if they even tried they point out that the energy gain that came out of the rig wasn't the result of fusion it was something else.

    That's the Cold Fusion Cycle. It has been about 5 years so I guess we are due.

  • 1. The total money spent on fusion research since 1960 is about 1% of the annual subsidy given to fossil fuels.

    2. Break even was passed about a decade ago.

    3. The current record for sustained fusion is 22 seconds or 2 minutes, depending on whether you believe the Chinese.

    4. Mini fusion reactors which reduce the stability problem were announced a few weeks ago.

    5. Renewables had just as many problems when their funding was throttled.

    • hahaha, "break even was passed about a decade ago".

      No it wasn't.

      Fusion at a net loss is done all the time in particle accelerators, for hours and days on end.

      you're delusional, there is no notable progress towards a self sustaining fusion reaction. are you believing some marketing spew?

      No, renewables don't have billions poured into them with nothing to show, unlike fusion.

      we already have a nice fusion reactor in the sky and know how to turn its energy into electricity.

      • $393 million a year is spend on fusion. Not exactly billions.

        October 2013, fusion scientists in Europe reached break-even. Ok, not quite a decade. 2014, the U.S. exceeds break-even.

        South Korea reached 70 seconds sustained fusion in December of 2016. 2017, China reached 101.2 seconds.

        Looks like progress to me. Fusion isn't where you thought it was. It moved on, even if you didn't. That happens. Recognize the fact and move forwards to today. No use dwelling on the past.

        Renewables aren't competing with fusion.

        • October 2013, fusion scientists in Europe reached break-even.

          You better go fix wikipedia, then. The article over there says that as of 2017 "the record for Q is held by the JET tokamak in the UK, at Q = (16 MW)/(24 MW) â 0.67".

          Of course over there they expect you to produce silly things like "citations", which we obviously don't require here.

    it will take a lot longer than ppl think. As it is, fusion is right around the corner.
    In the mean time, the CO2 is building up. We need to chase 4th gen fission here and now. If Gates really cared about AGW, he would be funding Flibe energy, and Thorcon, Both of these can not only use thorium (and we have plenty already mined), but also 'nuke waste' . In fact, we can burn up a lot of that waste.

    BUT, these billionaires are doing little to nothing on this.

    • We can have fusion in 10-20 years, if we spent adequate money on it and scrap the bans on cooperation.

      We've technology enough to build highly reliable self-sealing piping, which means a next generation reactor using sodium wood be perfectly safe.

      Most of the problem with fission is waste. We can reprocess waste to some degree. But nothing prevents us from storing waste in the reactor. Since you have more very long-lived isotopes than short-lived or stable ones, see if you can get them to do something interes

  • The physics of fusion is well understood - the combination of temperature, pressure and time needed are known. Plasma fusion machines generally scale to better performance with size, so the question becomes what field configuration meets the net energy generation requirements at the lowest system cost (presumably related to size).

    There are some tricks - hot ions fuse, hot electrons just radiate energy, so there are various tricks to keep the ion temperature hot relative to the electron temperature (neutral

    • Otherwise muonic fusion is painfully close to working, but still looks impossible. Cold fusion is exceedingly unlikely to work.
      Muonic fusion is cold fusion.

      • Usually when people talk about "cold fusion" they are talking about fusion in room temperature solid state materials. Muonic fusion can happen in room temperature hydrogen so technically it is "cold" fusion, but doesn't really fit the typical model. In any case it looks like there is no way to get out enough energy to make up for what was needed to create the muons in the first place (they stick to the helium atoms) so there is not clear path toward practicality.

We don't need free power to eliminate air pollution, we need clean power that's not more expensive than what we're using and the political will to build it.
