Fusion Power By 2020? Researchers Say Yes and Turn To Crowdfunding. 280

Luminary Crush (109477) writes "To date, the bulk of fusion research has been channelled towards a plasma containment and stabilization method. This is the approach used by ITER's tokamak reactor, the cost of which could exceed US$13.7 billion before it's online in the year 2027 (barring further delays). Researchers at LPP Fusion, in a project partially financed by NASA-JPL, are working in a different direction: focus fusion, which focuses the plasma in a very small area to produce fusion and an ion beam which could then be harnessed to produce electricity. It is small enough to fit in a shipping container, can double as a rocket engine, and would cost US$50 million to produce the working 5 MW prototype. To reach the next hurdle and demonstrate feasibility, LPP Fusion has started an Indiegogo campaign to raise $200K."

    It is not a mass market product with quick deliverables, it is an industrial solution. So the natural financing source would be venture capital, rather than crowdfunding. If they have to turn to indiegogo, it can only mean they failed to convince anyone relevant and are desperately trying to ride the "fusion is cool" fans, and disappoint them in the process.

Any investor with money already in one technology will push hard for only that technology to be funded, at the expense of all other lines of research.

          If there's a low entry cost, multiple risky options, and a potentially enormous payoff to whoever gets there first, you want to fund as many options as possible. That's why funding agencies and private investors alike take a pretty scatter-shot approach to lab-scale, sub-million-dollar energy research.

          Of course, if you have a high cost to entry, and a few high-viability options, as with tokamaks, then you have to be choosy.

          It should also be noted that 'cold fusion' did not work. It was not an issue of scaling, it was an issue of not actually creating a fusion reaction. There are still quite a few die hards around and there was some interesting offshoot work for creating neutron sources for medical work, but as a power source it was abandoned because it never existed in the first place.

        Part of the problem is that Mr. Lerner also favors a steady-state model over the Big Bang theory, so he is not taken seriously by the mainstream scientific community. OTOH, he does appear to know a lot about plasma behavior, and has gotten some interesting results with the small-scale "garage" experiments he's done thus far. If $200k is enough to get his work to the next level where he can show some more compelling evidence, maybe that will be enough to get some VC guy like Khosla to give him a few million more.

      I expected to see Slashdot drooling and rushing to catch a ride on the latest "ITER = Bad; everyone without much funding = good but repressed" bandwagon. Good to see the discourse is higher than that.

      That doesn't mean that ITER (or NIF, or any of the other major names) is going to be the best solution. Honestly, while there's little doubt in even most critics mind that ITER *could* lead to (via DEMO) a viable way to produce power, I seriously doubt it'll lead to an *economical* way to produce power. But the concept that none of the world's energy companies had an interest in a $200k power source that will change the world... sorry, but no. They looked at it, checked the science, and all decided it was a big "pass".

      Personally, I have the most hope for HiPER [wikipedia.org] leading to an economical fusion source. It's like NIF (ICF fusion), but uses far weaker (and thus dramatically cheaper) compression pulse, and makes up for the difference with a heating pulse. Basically, the capital costs are far lower and it gives more than an order of magnitude better gain than standard ICF. It piggybacks on the data from existing ICF fusion research, adding only a few new requirements of its own (such as research on how the heating pulse will interact with the high-energy state resulting from the compression pulse). And there's the standard challenges of any such pulsed fusion system, mainly about achieving a sufficient repeat rate. But it looks doable.

      • I wouldn't say ITER = bad, so much as ITER = big. For the amount of money that's been spent on that project, where's the harm in spreading a few million around the smaller projects too? You never know if any of them will bear fruit, and it'd be nice to be able to build a fusion reactor without needing superconducting magnets the size of a house.

        However, I really think that the cold-fusion idea was killed by stupidity prematurely, and --no offense -- I think that for those who want to work on a cheap fusion alternative, they should look at protein-folding to see if there is a way to get nuclei momentarily within a reasonable tunnelling cross section.

    The article states that operations are to begin at ITER in 2027. This is actually the date where ITER will be operated using a Tritium and Deuterium plasma, as opposed to a Deuterium only plasma. Nearly all tokamak experiments currently undertaken are using Deuterium-only plasmas to investigate how the devices operate. Adding Tritium to the mix means that a Tokamak can reach fusion temperatures, but it requires extremely delicate handling. A Tritium plasma is safe, but it's important to keep track of all of it (and that includes losses to the vacuum vessel of the tokamak, we really don't want any going missing!).

    Plasma experiments are set to begin in ITER much earlier, with a `first plasma' date in November of 2020 using a Deuterium plasma. It should not be understated what we can gain from experiments using a Deuterium-only (which means no fusion) plasma. ITER will be used in this manner for several years, while we gain better understanding of plasma physics on these scales. When we have a good feel for the machine, then we will start to produce fusion with a `DT' (Deuterium-Tritium) plasma.

    I'm very busy right now and have only had a cursory glance at the article, but I'm reading things such as `Moreover, because the end product of the reaction is moving charged particles, those can be converted into electricity directly', and thinking that at least the writers do not have a detailed knowledge of plasma physics. Tokamak power plants would use the energy of the 14MeV neutron produced by the DT fusion reaction to heat water to steam and generate it directly. `Moving charged particles' is just a plasma, just like in a flurorescent light bulb. You can make a current out of it, but not electricity.

      I thought that's what MHD generators were for? Given that the output would be in form of plasma, it just seems a natural solution to the problem, even if you recover the remaining energy using a steam cycle. (Of course, in tokamaks, that particular design might be difficult or infeasible. Of that, I haven't really thought yet.)

      Uh, a plasma contains charged particles, but is neutral overall (normally). And the particle motion is undirected. What they claim to get out it is a pulsed, directed beam of multi-MeV 4He ions (and only those -- the electrons fly away in the opposite direction), which could be converted into electricity directly (via induction).

    I am sorry, that sounds like a suspiciously "pie in the sky" project to me.

    First of all, nuclear fusion is insanely difficult. OK, maybe not *that* difficult, more like: "Easiest way to get fusion is to get 1.99x10^30 Kg of hydrogen in one place" difficult.

    Now, coming out of nowhere, we have people saying: "Give us US$ 1,000,000 and we will give you portable, safe fusion within 6 years!". Sure, people, what makes you think you can do better than, say ITER? New approach, yadda yadda yadda, sure, I have heard that one before. Whatever the "new approach" was, it did not work the first time, it probably won't work now. Insanely difficult problem, overconfidence of the new kid on the block, and all that

    Second, the old "Fusion power is clean!" saw. No, it is not. Fusion generates insane temperature and neutron radiation. What makes you think you can put everything in a small container? What happens to all that energy dissipation? To the container and its surroundings? If you RTFA, these people are saying thay can generate up to 5MW in a containment chamber "small enough to fit in a garage"! Excuse me? No dangerous radiation, perfect containment in a completely secure, small package? Hmmm... The Engineering does not seem strong in this one.

    Third argument against: EROEI. Sure, you can get fusion going in a very small spot. We know this, it has been done before, using several different technologies (See Z-Machine at Sandia National Lab, for instance). BUT... (a) how much power do you have to pump into these capacitors to even *create* fusion in the first place? (b) creating fusion can be done... but what about *sustaining* a fusion reaction? In other words, if it takes you 20MW of power to sustain 5MW of power generation, where is your EROEI? Oooops... There is none.

    Final nail in the coffin: "We were financed by NASA-JPL". So what? NASA funds thousands of projects per year. JPL, probably hundreds. And don't get me started on the NSF or DARPA, (or whatever local equigvalent exist in your country), OK?They certainly fund some pretty weird things, just on the off-chance that XYZ wild theory could prove interesting. Or, even better, that XYZ wild theory will be conclusively disproved. That, in itself, does not mean anything. It certainly does not mean your project is headed by cool-headed, super-smart, seasoned engineers and scientists: just that your weird project received a bit of money from whatever popular government entity you could contact.

    As a matter of fact, if your project was so smart and so innovative, *and* headed by cool-headed, super-smart, seasoned engineers and scientists, you probably would not have to ask for money on IndieGogo or other: smart money would flow, by the millions, into your coffers, again just on the off-chance that super-duper weird idea could prove to be the real, "fusion in a box" thing that could change the world. Seriously. And don't give me that conspiracy crap that big oil does not want you to be independent yadda yadda yadda: there is so much money floating around right now, looking for ROI, and so many (rich) people ready to tweak the nose of Govt (See: The Intercept) that a serious project like this would get funded 10 times over. WhatsApp sold for *billions* of dollars for Pete sake! What makes you think portable fusion reactors could not get funded? Get Elon Musk or Mark Zuckerberg on the phone!

    All in all, this does not sound very serious. More like the romantic fantasy of the genius guy in a garage changing the world one micro-fusion reactor at a time. Sorry.

      The problem I have with this project is that they are making extraordinarily bold claims (they even have a power rating for the product) which should require extraordinary proof, and need to be vetted by very serious scientists to be believable. Should that happen those scientists would have no problem getting the funds from governments or private investors, banking on their reputation alone. The fact that they have convinced no reputable scientist and have no peer-review scientific output, but have already embarked on a commercial venture should be a huge red sign, this is not some smart gadget you can patent and make a fortune on, it's hard science where theoretical results are typically decades ahead practical applications.

By using Hydrogen-Boron you can avoid the neutron radiation problem. But in exchange you have to have a temperature 10 times what we've failed to produce for a long enough time to get energy back from the more common fuels. The article also mentions that a lot of the energy released would be photons, which are harder to convert into electricity.

    Hydrogen-Boron and radiation free would be nice and so raises the profile of this work and perhaps makes it more crowd funding friendly. But without more explanation makes me even more suspicious that they are saying all the too good to be true parts and skipped mentioning all the reasons it's not likely to work. On the other hand it would be nice if boards of competent scientists could invest some real money in slightly crazy ideas that were allowed to fail without politicians going nutso that when you tried 10 things with a chance of success of 10% only one worked.

    I'd rather we funneled energy research money into something we could implement wide-scale by then. Like LFTR.

    Once we've got plentiful energy, THEN we can go chasing after fusion.

    This was tried as the Trisops Project [wikipedia.org] 35 years ago but lost funding because all of the fusion energy project's focus was on the Tokamak.

    Trisops was an experimental machine for the study of magnetic confinement of plasmas with the ultimate goal of producing fusion power. The configuration was a variation of a compact toroid, a toroidal (doughnut-shaped) structure of plasma and magnetic fields with no coils penetrating the center. It lost funding in its original form in 1978.
    The configuration was produced by combining two individual toroids produced by two conical pinch guns, located at either end of a length of Pyrex pipe with a constant magnetic guide field. The toroidal currents in the toroids were in opposite directions, so that they repelled each other. After coming to an equilibrium, they were adiabatically compressed by increasing the external field.

      Do I understand correctly that you have worked on that project? If so, could you comment on what the people on LPP Fusion are doing? Is is feasible / safe / sustainable?

        I'm passingly familiar with the compact toroid concept, having written *that* article on the Wiki.

        Generally speaking it appears the approach is unworkable. In spite of great interest in self-stable configurations, confinement time remained on the order of nano-to-micro seconds, and energy losses were higher than expected. It was not clear whether these could be solved, but it was clear that finding out would cost a lot more money. The apparent low-cost path to fusion did not appear to be so low-cost, and that seems to be the reason the funding was cut.

        In the case of DPS it's not clear to me that anything new has been demonstrated. A quick look over the cites on various wiki pages show a very low level of development and nothing that could be considered any sort of non-linear progress. In the case of LPP, their announcement of a 1.8 billion degree plasma after 30 years is hardly encouraging, given how quickly progress had been prior to then.

        More controversially, many of the claimed benefits of the design are supposed to come out of a never-before-seen interaction which remains undemonstrated. I remain skeptical that such a thing even exists, and certainly don't take Mr. Lerner's computer models as a reasonable argument - consider LASNEX.

        It is worth mentioning that CT's form the basis of at least some MTF systems, and these *are* seeing a significant amount of development today. Whether this is the path to the moon or simply another finite tree remains to be seen. Some consider spherical tokamaks to be CT's (I am *not* one of those) so they add MAST and similar to the list, but these projects have also apparently hit their brick walls.

  • Just for reference, this appears to be a Google TechTalk presentation by their chief scientist about the subject. It's 7 years old no less.

  • The company's Chief Scientist is listed as Eric Lerner, a name I thought I recognised. Turns out he's a noted plasma cosmology crank.

    I just don't see how making promises like this is good for anyone. Clearly they are just looking for funding; no scientist or researcher in their right mind would promise something they can't already do by a specific date unless they were lying (or guessing, call it what you want) in order to get funding. This is the kind of crap that makes simpler people no longer "believe in science."

      Just wanted to add: If there is research that needs to be done that is not, by itself, profitable, then I believe we should consider funding it without forcing the researchers to make PR statements like these because who knows what ideas or conclusions that research might actually lead to -- It's really too bad that we are so focused on all research building profits for someone. We, as a society, suck at thinking about anything long-term.

  • After reading this story and this older story [slashdot.org] (which has 5 backers and a nice 390 Euro beer kitty) I can't help thinking I want in on this action.

    Do I need to invent a ridiculous company idea or is it enough to just ask for donations for my holiday fund?

  • This would be a wonderful joke to play on ITER. All those bureaucrats would be so ticked to have to actually go back to science. What I love about FirstFusion is that not only does promise to be a small reactor, but that in all likelihood when it starts to work properly that people will figure out all kinds of improvements to make it smaller and more efficient.

    People think about how this will change the world; but I suspect that it would result in all kinds of interesting and new things well beyond the u
  • In a few years, they will rename the device to "Mr. Fusion".

A good supervisor can step on your toes without messing up your shine.
