Finally someone puts the actual grid input numbers in their video for the LLNL fusion experiment. Thank you.

[@murasaki848]

My high school class visited the Princeton Tokamak in 1983, so I got caught up in the scientists' enthusiasm (especially when they related the story of trying to mix batches of epoxy that were too big so they caught fire). Eventually, I had to give up following the research on fusion reactors by the early 1990s because it just got too depressing, though it keeps dragging me back on occasions like this. Fusion was always "10 years in the future" in the 1980s, and the saying started to become "20 years in the future", then derisively "20 years in the future and always will be." In the early 1990s, the International Thermonuclear Experimental Reactor was announced, attempting to bring all the world's fusion expertise to one massive design. As of 2016, the cost estimate for that project alone was €22 billion, and as of their current website its estimated first fusion will still not be until quarter 4 of 2025. Recently, I heard of another company in Seattle, Helion, that's doing a radically different design, basically accelerating two deut-He3 plasma donuts at each other and drawing electricity directly from the disturbance of the magnetic field as the plasma fuses. Seemed exciting, and they say they're close to commercial success, but I noticed they don't publish a lot of numbers about their system, especially ones regarding how close they are to net positive... Now we have this exciting announcement that net positive energy has finally been achieved. From what I can see from the press releases, it's a "z-pinch style device", one that sets off a one-shot supercooled pellet of deut-trit. So it's not like a fission reactor or a tokamak like ITER, which are designed to be continuous reactions, but instead more akin to a car motor, which uses a sequence of carefully timed explosions to create power. This experiment is akin to finally achieving efficient enough combustion in one cylinder in a car to generate more power than the actual spark from the plug. Now all they have to do is invent something that will, like a car motor, turn these "one shots" into a continuously running power source, only using a supercooled bit of hydrogen and lasers that soak over 100x the power. The engineering on that should only take... according to the press releases... 20 or so years... Depressed. Crawling back into my cave now.

Fusion power plants are great in theory, but... We're already using a lot of fusion power. Today it's even a fair amount of direct fusion->electricity conversion rather than going by some intermediary stage. And honestly it's probably cheaper and more practical to build energy storage and more efficient grids for the solar plants than trying to smash atoms together down here... 😊

[@jschreiber6461]

Great commentary on the fusion energy payback. The core reaction did indeed produce considerably more energy than was injected by the lasers, and that should be the main focus. The issue around how much energy was used to produce the ignition energy laser pulse is a distraction. Lasers have ALWAYS been terribly inefficient, maybe this could be done with somewhat more efficient LED lasers, and all the supporting electronics made less wasteful, however that is a different issue. Other researchers using alternative more efficient ignition methods, particularly private ones, should be hugely encouraged by this result.

We've been seeing some great meteorite falls lately. I'm trained to collect in field data to help recover witnessed falls. Taking measurements using video images where we see a meteorite causing shadows from objects like street signs ect . We use doplar radar if we have covered and that usually does the trick but sometimes we have to triangulation using anything we can . Alot of people think they can tell how far away meteorites land when they seem them go over the horizon. They get really mad at me when I tell them they can't and that its an optical illusion that the meteroid went over the horizon. If I say I saw something and how far away it was its because I could actually tell . Most people don't understand that .

The break through in fusion is great! But it the media coverage was problematic: often it was claimed in the headlines that there was more energy produced than comsumed, but this is only if you ignore the massive amount of energy needed to run the lasers. This was often not mentioned in the media unfortunately

[@davidbrydon4288]

I assume that extra energy covers the energy that gravity would give in natural fusion in a star. If that’s so then fusion will never happen.

[@johnbennett1465]

@@davidbrydon4288 incorrect. The lasers are very inefficient. Something like 100 watts of energy goes into them for each watt of laser output. The rest is lost as waste heat, running cooling systems, etc.

[@lokilawson]

@@davidbrydon4288 actually the energy could end up self sustaining if one were to balance the influx of hydrogen to the creation rate of helium. One would harvest off a portion of the excess energy for our use, leaving enough energy to continue the reaction. This is what she meant by ignition. More energy came off the fusion reaction than was consumed by forcing the atoms together. The problem, as it were, was that the lasers used to initiate ignition are consuming energy just to run them. And that consumption in this particular instance was way more than the yield. It actually isn’t much of a problem. The issue here is that scaling everything up to a level that it would actually be useful is years, and a lot of innovations away. This news is exciting as a milestone, but it really isn’t all that surprising. We sort of knew we would get here. It is just that here is a very long way from the finish line.

[@ivoivanov7407]

​@@davidbrydon4288 The experiment was dome by old and very inefficient lasers (300 MJ in, just 2 MJ out),. But, there are some good news - according to my colleagues that are into lasers technology, today's best lasers would require not 300 MJ but "just" 100 MJ. That is still way off the goal, but a big step into the right direction.

I'm hopeful for viable commercial fusion within less than two decades. Technology has been shown to grow exponentially. With better AI and even faster computers constantly being developed it's only a matter of time. The race between technology and climate change has truly begun.

[@TonyVallad]

Yep, I think the same. The way things are going I'm really hopeful we get some AMAZING technology really really soon. Much sooner than most people think.

And I'm not even talking about science discoveries and new theories that will come up in the next years, it's going to be mind-blowing !

[@skierpage]

No, climate change is winning by far. We have to almost completely stop burning fossil fuel long before fusion will make a dent. "The GCP's estimates put the remaining carbon budget for 1.5C - specifically, the amount of CO2 that can still be emitted for a 50% chance of staying below 1.5C of warming - at 380bn tonnes of CO2 (GtCO2). At the current rate of emissions, this budget would be blown in just nine years."

I hate to be the bearer of bad news, but efficient fusion won’t solve any problems. The problem doesn’t lie in how to generate electricity. The problem is in how we govern ourselves. Mark my words, even when we get efficient fusion, nothing in the world will change: the rich will continue to get richer and more powerful while the poor get poorer. It’s time for major reform. Actually it’s probably too late

18:20 It's easy to account for the "ghostly glow", as we can only account for known sources of light. If you look at the deep field survey you see that an area of sky that was previously thought empty actually has lots of galaxies emitting light at us but we can only see them if we do a long exposure capture. I'm sure that as out equipment gets more advanced we'll be able to go deeper and deeper and see more and more stars. So I say the glow is just the light from galaxies we haven't identified yet.

[@Odin029]

According to a researcher who retired from Lawrence Livermore, that laser system was chosen because it had the best mix of reliability, controlability, and power output, not because it was the most efficient. That laser used fairly old technology even when it first built and installed. So I'm excited about the fusion ignition because now it becomes more of an engineering problem than a scientific one, and engineers work fast when there are dollar signs dancing around in their eyes.

[@skierpage]

It's hard to rush multiple engineering challenges. More efficient lasers is just a small part of the problem. E.g. the hohlraum target that ignited is a gold canister containing a precision-manufactured pellet of DT fuel, both very expensive. Even if you could somehow ignite one 10 times a second, the fuel cost is very high.

[@SpeakerWiggin49]

Here's a trippy thought experiment: Try envisioning the volume of space visible as you look further away, back in time. As you go back in time, the distances at z13 reveal matter in a _larger_ space than those closer and more resolved. The empty space at z13 is less technically, so you get to see _more_ of the matter that first coalesced into stars and galaxies from the Big Bang. This has allowed me to grasp 4D dimensionality much better for the purposes of cosmology.
