    Re LK-99 superconductor, I have followed a bit on this, and one takeaway is that the material is NOT as simple as may seem to create. In short, it is a crystal-like structure that has many engineering steps to precisely form; you can't just mix something together and voila. Even if legit, we can expect many failures in reproduction since this is all very niche knowledge particularly engineering wise.

    "We have never had this much fun since cold fusion" .. oh that stings - could not have put it better.

  • @TerryBollinger
    @TerryBollinger Год назад +88

    Thank you for the LK-99 update! One difference from “cold fusion”: While this early set of mixed-bag, leaning-towards-negative set of outcomes in no way constitutes proof of the reality of the effect, it is nonetheless at least two or three orders of magnitude _more_ positive than the reproduction outcomes a month after “cold fusion” was first announced.
    Why such a high ratio? Because the one-month-later results for cold infusion were uniformly zero. In sharp contrast, at least a few labs appear to be having some difficulty _disproving_ the idea. That’s unexpected, and not at all like the stark futility I so vividly remember in the cold fusion aftermath. (I'm _old._ :)
    The other striking difference is they have a theory for this, one with solid correlations and some indirect verification from the well-established existence of room-temperature superconductivity in high-pressure physics. Another point that is conspicuously different from cold fusion is that if some group can prove they have achieved the same crystal structure at room temperature that has been proven to provide superconductivity in high-pressure physics, they have a genuinely solid theoretical leg on which to stand. That never happened with cold fusion.
    You are now my go-to place for updates on this fascinating issue!

    • @Leyrann
      @Leyrann Год назад +13

      Another difference with cold fusion is that room-temperature, room-pressure superconductivity is an extension of what we have already found (we have found atmospheric pressure superconductivity at low temperatures, and high-pressure superconductivity at _almost_ room temperatures, like around the freezing point of water), whereas cold fusion basically came completely out of left field. It's not a reach to say that a room-temperature, room-pressure superconductor is a matter of time, as opposed to a matter of possibility.

    LK-99 may not be the one, however the physics behind do point to some interesting superconductor behavior if the copper atoms are arranged correctly similar to what they reported and therefore there is a very real possibly a whole new class of latice contraction superconductors which could lead to a real break though within a few decades or even years considering the high motivation to be the first one to get a working room temperature superconductor. I think those scientists who were working on synthesizing LK-99 ran similar simulations and had been attempting to replicate them in a successful experiment.

      Star Trek is fantasy and allegory but this tech can potentially be used for cooling purposes, and I think may already be. There's a cooler of a chip now that probably works like the ultrasound pad in the vid. It can vibrate individual cells (or all at once) which accelerates air molecules upwards at high speed. A lid with horizontal fins sits on top of the cooler chip so air shoots out the sides. This lid also absorbs and radiates heat away. 2.5mm high instead of 4mm for the current heatpipe and fan combo, and using much less copper and plastic.

    Defects in the crystalline structure likely would make it difficult to replicate superconductivity in LK-99. Pressure may also be a factor, and in the case of having a decent size chunk of the material, the interior pressure could be much higher than the ambient pressure.

      @@kamikeserpentail3778 Actually, defects in a material can alter the stress and strain in a material, and thus make some internal regions high pressure. It's possible that a high pressure superconductor could work at low ambient pressures if it had large enough defects which were connected. Imagine a cubic lattice with a defect increasing the lattice spacing in a given region. The external region wants to persist with its smaller spacing, and therefore tries to compress the defect, making it high pressure. So defects can actually be quite amazing.

Small defects have significant effects in regular semiconductors, so it is expected small differences will produce substantial differences in properties in something as exotic as a room temperature superconductor.

    • @Laff700
      @Laff700 Год назад +1

      ​@@daysofradiation Probably not. If you do want some second law disproving hopium though, there's this thing called relativistic heat conduction which takes the finite speed of light/second sound into account and allows you to model heat flow more realistically. It allows for fun things like thermal shockwaves and resonance. It also allows the formula for local entropy generation to go _negative_(I.E. heat flowing from cold to hot). It's currently thought that this doesn't violate the second law of thermodynamics because locally the system might not be in equilibrium and therefore our usual notions of thermodynamics and temperature don't really apply. Recently stumbled upon it myself and it seems pretty fun. It seems like in order to properly model it, you have to use coupled equations regarding the evolution of the heat flow vector and temperature.
