What is fusion ignition?

Ғылым және технология

On Dec. 5, 2022, LLNL made history, demonstrating fusion ignition for the first time in a laboratory setting - an achievement six decades in the making. Fusion ignition will provide unprecedented capability to support the National Nuclear Security Administration’s Stockpile Stewardship Program and invaluable insights into the prospects of clean fusion energy. What is fusion ignition, how did it happen at the National Ignition Facility and why is it important?

    The more energy that was received outside was 20 billion of a second, that's all we needed to confirm Fusion is the future, scientists already working on compact Fusion reactors and now I'm seeing compact Fusion reactors that are even smaller and require less space and a more capable because of free enterprise 1:34

    Did the ignition equation include the energy spent producing the fuel pellet? Or is it a negligible quantity? When the lasers fire, and when they compress the fuel pellet is it loud? Does it cause significant wear and tear on the capacitor banks, SCR's, bussing or switchgear?

    Watching the simulations in this video are exciting! More videos with the main focus on the mathematical modeling/numerical simulation aspects would be extremely interesting. Why do they make the pellets so smooth with such precision? Nature is so non-linear and fractal it seems that they are "looking in the wrong direction?"

Read the wiki article on it or go to the NIF web page.

    We must not belittle the effort the folks at the National Ignition Facility have put into this, but it is appropriate to criticize the hype they have put out. They simply got really excited because they finally achieved what they originally claimed they would achieve no later than about a decade prior. It was not a breakthrough. It was merely a modest step up in energy released as compared to a similar test they did a year or so earlier. Three megajoules sounds like a lot. How much energy is three megajoules? Three megajoules is three million watt-seconds. In comparison, one kilowatt-hour is three point six million watt-seconds. I pay about twelve cents per kilowatt-hour for electric energy delivered to my home. So, if they could convert the energy to electricity and deliver it to a user at 100% efficiency, it would be worth about ten cents. They stated that if they could have caused all the fuel in the pellet to fuse, they would have released about 40 times more energy, if I remember correctly. So that would have been worth about four dollars assuming they could convert all the released energy to electricity. Using their present approach to releasing the energy, they have to procure the deuterium-tritium fuel, cryogenically cool it, place it in a micron-tolerance diamond sphere, place that inside a precisely made hohlraum tube containing gold as well as other expensive stuff, precisely place the assembly in position, and blast it with 192 huge lasers. It should be clear that they are not on a path to achieve the dream of cheap abundant clean energy for the world. At the time of announcing their “breakthrough”, they said they expected to repeat the experiment on about a monthly basis, and expected to continue to extend the energy released. Since then, it has been about a year and so far they have announced only one shot that released any more energy than the “breakthrough” achievement. Since the 1950’s, there has been no doubt that mankind can release more energy through fusion than the energy put in (think hydrogen bombs), but the question remains whether we will ever have a cost-effective commercial power source using fusion produced on earth. I hope these folks can at least succeed in their primary mission of assuring nuclear deterrence.

    And I saw it immediately you have a direct beam of laser energy hitting the Isotopes and all of these particles are directed but you have it coming from One Direction you have to contain the entire field to achieve Fusion otherwise neutrons are flying right into the system that we're sending all the data from the neutrons are going everything the whole thing is going to clap the hall around and the hydrogen isotope has to be contained in a spherical field so none of the particles that can get out and if particles get out you can control them and you can see them, they finally figured it out, did my calculations was exactly 5 years and I was one of the first scientists that realized when we found the Higgs field, I saw it, I saw all the data coming from large hard drawing collider and everything like this and I said we were up at my calculations we were at 1:08, and they couldn't be more than that because none of the particles were consistently working with the formula and we have a accurate formula the Higgs particle was generated generator and detected many years before it was I think it was three or four years before we were able to confirm that this is the Higgs, when we saw it and you know what I have to thank all of you guys for being so geeky but still keeping focused on what really matters the Higgs particle was generated at 1:08 gigahertz, it was generated there and we saw the data coming down and you know what me I'm too stupid I'm just a regular guy that likes to eat hot dogs and and treat girls right on a date I'm nobody special but, I saw that we had generated the Higgs particle, and I recognized it and you know what we collect trains of terabytes of data but we never nobody ever gives explanation of how the state is processed but I've seen it, and nothing I'm going to tell you is that if you don't realize that the aliens are out here, all you have to do is pay attention to Common Sense, I looked at all the you know what I'm looking at a 6550 time machine, it's heavy is the most heaviest piece of Machinery that have been created on Earth, and here I am a regular guy, that's God has given me the ability to understand what this is

    The problem with the Hologram is that it was not spherical and it was not able to contain and control the neutrons and they had another words if you going to extract energy from something make it like around spear don't make it like the whole ramp all these neutrons and everything is hitting every particles and everything before it could contain you can't contain the field, that's what I'm saying you can't contain the field you can hit the hall around with 60 million degrees temperature but all of the energy is going the neutrons are going to take over and it can't work, it can't work because the Hologram is not round everything dealing with this test of 20 billion of a second it has to be Sparkle it has to contain all of the energy that we put in it neutrons are going everywhere, you can't have that and that's why it didn't work on the first experiment, birthday you know I had to tweak him a little bit but then they figured out if you're going to have a fusion reaction that all of the energy must be contained in the same space like a circle like the sun

    So, they collide and generate/release potential. More out than in doesn't violate physics because the energy potential already exists, and you need to initiate the reaction to release it. Mentioning Einstein still sickens me though. His equation only regards defined systems with known mathematical conditions and the conversion of one mass into another, and how much energy can be generated and recovered during the length of time it runs on X amount of source within that known and defined system. *This is why the reference to Einstein rubs me the wrong way. His theory is just so greatly misunderstood, and people reference him to convince the general public of laymen of anything.* I have invented systems that will produce far more out than in, but again, it's a misleading statement and must be explored further within the systems I have invented.

    "Fusion Energy" is a pleasant sounding term, but for energy generation, viable fusion energy production will most likely be hundreds of years out, if ever. Stars do it so easily because gravity is plentiful (and free) at the core of a star. Not so much in a building on the surface of the earth. Thus, the energy requirements needed to compensate for the lack of gravitational energy will always vastly outweigh the useful energy output. But any first year physics major knows this.

    @@deltonlomatai2309 Neutrons on their own are not radioactive. Neutrons penetrate something called the breeding blanket lined with lithium to produce more tritium and more neutrons to keep the reaction going. A neutron carried no charge, it is non reactive. Radioactivity is the decay of particles which leads to HIGH ENERGY particles that can break DNA. Hypothetically if you were caught in the reaction your DNA would be scrambled but that would be the least of your worries. Coal kills more people due to radiation than Nuclear does. Edit: The breeding blanket also does contain elemental uranium, which overtime will become radioactive I forgot to mention this. The only issue is disposing of the blanket itself not the outside of the walls.

    Or, someone will invent something relative to releasing potential energy by inducing a reaction that requires less in that will come out. Einstein's theory is grossly misunderstood because his theory is grossly misleading. I have some strong and sound theories on a particle accelerator to collide sub atomic particles and possibly, release more potential than was required to generate the reaction. *Until then, I have invented a new solar generator that is exponentially superior to our modern semiconductor photovoltaic cells.* That one I know for fact works, another I will need to test the theory in my lab, but also believe the output will be even greater than the other system I invented. *Harnessing the sun's energy more effectively gives the misleading impression of "free energy", but my current working system is so efficient, electricity could eventually be "free" of monetary exchange.

    While ignition is definitely worth celebrating, this whole thing feels deliberately misleading. Sure you got more energy out of the _pellet_ than what went into it, but the _the system as a whole_ is still a massive energy sink. That laser power didn't come for free. This is disingenuous at best and an outright lie of omission at worst. While the public may be fooled, those that follow science news and subscribe to channels like this most certainly will not. And the big questions still remain; how do you plan to have a net energy gain, and how do you plan to do it reliably, repeatably, and cost-effectively enough to be a viable power source? I get it; a lot of work has gone into this and some really great science has come out, and you are proud of that. Rightly so. But hyping it as the future of power generation is not even wrong

    Uh... is whole video is a joke? The laser pulse is measured in femtoseconds the amount of energy produced is about that of a couple hundred matchstick heads burning themselves down to nothing. You need to store the energy to make the laser pulse first. Was there enough energy made by the reaction to recharge those lasers? No. So why not? The laser efficiency is very low. Only a small percentage (around 1-3%) of the electricity stored in the capacitors is output as photons in the laser beam. Most of the electrical energy is wasted as non-laser emission heat because the diodes are nowhere near capable of converting anything even close to the majority of electricity into a laser. This is not the perpetual energy machine that fusion promised to be and the reason is clear. You can't cheat nature (aka: the laws of physics). This wasn't a breakthrough.
