Mystery Company Blazes a Trail In Fusion Energy 144

sciencehabit writes: Of the handful of startup companies trying to achieve fusion energy via nontraditional methods, Tri Alpha Energy Inc. has always been the enigma. Publishing little and with no website, but apparently sitting on a cash pile in the hundreds of millions, the Foothill Ranch, California-based company has been the subject of intense curiosity and speculation. But last month Tri Alpha lifted the veil slightly with two papers, revealing that its device, dubbed the colliding beam fusion reactor, has shown a 10-fold improvement in its ability to contain the hot particles needed for fusion over earlier devices at U.S. universities and national labs. 'They've improved things greatly and are moving in a direction that is quite promising,' says plasma physicist John Santarius of the Fusion Technology Institute at the University of Wisconsin, Madison.

      There was seriously a Google ad on this page for the "Power Innovator Device" (I won't link to it), which the inventor emphatically explains is NOT FREE ENERGY, but will reduce your electricity bills by at least 80%. (spoiler: it's inductive coupling with a pancake coil).

    They've got to 5 milliseconds but they need approx 1 sec burn before fusion begins? Long way to go folks :)

    • They run at a different regime where 5ms (up from about 100microseconds) could be more than enough. The collide two RFC and this should heat them quickly to fusion temps. Even better most of that "heat" will be in the ions rather than the electrons.

    Based on historical precedent around fusion press releases, I would venture to guess is that huge pile of cash in the "hundreds of millions" is starting to run out.

      Almost certainly the case on three grounds.

      (1) Getting a serious fusion effort off the ground is fabulously expensive. Even if you have some kind of whizbang micro-reactor concept you need a small army of physicists, engineers and highly skilled fabricators. People who don't come cheap.

      (2) Running out of cash is what most startups do.

      (3) They probably didn't have as much cash as "everyone knows they have", for the simple reason that the best way to convince someone to give you the mountain of cash you need is to make them thing you've as good as got it from someone else.

  • Didn't Tony Stark and Stark Industries invent this already? This is a lawsuit ready to happen! Not sure what these people are thinking stealing these ideas when everyone has seen the documentaries that have been in the theaters!
    Has there been any comment by Tony or any press agent from Stark Industries?

    They are getting plasma pressures at levels similar to tokamaks and stellerators, which is pretty impressive, while using a fraction of the magnetic field. If you didn't know, 1 keV temperature is a little over 10 million K, and a density of 10^20 m^-3 is close to vacuum, but because of the high temperature the pressure is fairly significant, on the order of one atmosphere. It's refreshing that they don't exaggerate their progress (they admit that tokamaks are more advanced as of yet). But if they were trying to offer a cheaper alternative to tokamaks, they have a way to go. At 23m long, their FRC is not small. If they need to scale it up considerably to reach reactor levels, well, it's going to be an expensive project like ITER is.

    If the FRC turns out to be the way forward, most our research into tokamaks hasn't been wasted. There's a lot of overlap in the theory and the technologies used. Neutral beams are also used in tokamaks, for heating and diagnostics, and are also being used to provide torque to the plasma, which can stabilize the plasma in various ways which can be understood in turbulence theory. The NIMROD code is also used in tokamaks, as is the technique of lithium wall conditioning. I suppose the point is, a lot of slashdotters will condemn the work of government research but this research wouldn't have been possible without decades of groundwork backed by government funded grants.

    We already have a fusion reactor, that pumps mega-giga-tera watts of energy and works without any serious maintenance issues. Just improve the ability to collect its output, some capacity to smooth out the fluctuations in the collection. It is a stellar idea, but I don't know when it would dawn on to the general public.

      Think big.

      How well will that work in interstellar space?

      Not so well as having a local fusion reactor.

    • I've heard rumors of this device and it's claims of a bright future. Ridiculous! Why, such a device would have to be millions of times larger than Earth to be sustainable. It would also have to output energy 24/7 with no more than 5% variation. It would probably even be dangerous to look at without eye protection and the simulated output models indicate that it would significantly increase rates of skin cancer in certain vulnerable individuals. Such a dangerous, impossible to build device is just more blue-

    • It's actually got really crappy efficiency. I produce much more heat than a section of the inner Solar core of the same volume, although I need a LOT more input. Fortunately, it's a LOT bigger than I am.

    "has shown a 10-fold improvement in its ability to contain the hot particles needed for fusion over earlier devices at U.S. universities and national labs"

    No, that is inaccurately broad.

    The correct statement is has shown a 10-fold improvement in its ability to contain the hot particles needed for fusion over earlier **FRC** devices at U.S. universities and national labs"

    Earlier FRCs sucked by about four or five orders of magnitude. This sucks by one less.

    This is not a breakthrough. T-8 was two orders of magnitude better than Stellarator C, but 45 years later it's still two orders too little to be useful.

    From the paper

    Large FRCs are produced in C-2 by collision merging of two CTs.3,13 Figure 5 shows the evolution of the excluded flux radius obtained from a magnetic probe array in the -pinch formation and central sections. Time is measured from the instant of field reversal in the -pinches, and distance is relative to the system midplane. Multi-gigawatt pulsed-power modules drive the -pinches, briefly reversing the magnetic field to 0.5kG, then raising it forward to 0.4kG, with field-reversal occurring by t5s. The two CTs so formed then accelerate out of their respective -pinches at supersonic speeds, vz250km/s, and collide at the system mid-plane at about t30s

    Disclosure. I am one of the authors of the paper referred to in the article.

  • I'm not a physicist, so forgive the possibly dim-witted nature of the question, but let's assume they can contain a fusion reaction some day. How might we actually use that to create energy that people can use?
    • This is not a dim witted question. Actually it is a profound engineering question. The simple answer is to liken the fusion reaction to the coal burning in a steam engine; therefore in the end we could just be boiling water. The difficulty is that fusion occurs at temperatures of millions of degrees and any machine you can conceive of to capture the energy is necessarily going to make "contact" with plasma. There are a number of concepts about how to do this, google the "first wall" problem for a taste of t

      • So, if I understand you, we just construct some kind of wrapper around it that can get hot and won't melt and just make steam? ... a wrapper with "... like diamond coating, with a boron flavor to it. :-_)" [from a physics blog I found with google] ... and treat it like a big super-duper-hot pile of burning coal? It doesn't seem very elegant, to my untrained eye. Ah well, it's for people smarter than me to figure out, I suppose. Thanks for helping me frame the question.
      • The simple answer is to liken the fusion reaction to the coal burning in a steam engine; therefore in the end we could just be boiling water.

        I'd love if we could get away from having to boil water or it's going to be a right pain in the backside trying to build one into a spacecraft. Perhaps betavoltaics like the Nuclear Lightbulb fission reactor concept?

  • Yep, and it'll take 10-20 years to commercialize the product.
