    I was going to write something about Gordon Freeman and Resonance cascade failure. And then I saw that it was AI generated, and that explains a lot.

    At least they disclosed that it's ai.

    This news is two years old and is from the garbage pile that is timesofindia. It doesn't deserve to be posted in a tech community.

    artificial sun

    You can just say fusion reactor

    This development by the Korea Institute of Fusion Energy (KFE) is another move towards achieving clean fusion energy, whose ability to generate unlimited amounts of electricity with little to no carbon emission is promising.

    The article, like so many others concerning nuclear technology, refused to address the unit cost of energy.

    Why is building a large, complex, and temperamental fusion engine more economical than churning out an equivalent number of wind turbines or solar panels? The article doesn't say

    For the same reason someone would have asked "why is building a large, complex and hard to produce solar panel more economical than churning out an equivalent number of coal plants?" decades ago.

    It's improving the tech, which could eventually far and away outpaced every other energy producer. Maybe not now, but in the future. Some are just gung-ho about trying to produce a bunch when they're not quite ready.

    You can just say fusion reactor

    The Times of India is a rag that literally accepts bribes for positive coverage; sensationalist garbage is their bread and butter.

    But it gets worse: this story is over two years out-of-date.

    The KSTAR Research Center at the Korea Institute of Fusion Energy (KFE) announced on the 20th that during the '2023 KSTAR Plasma Campaign' conducted from December of last year to February of this year [2024], it achieved a 48-second operation of ultra-high-temperature plasma at an ion temperature of 100 million degrees and a record 102-second operation in high-confinement mode (H-mode).

    This happened back in 2024. Here's a paper.

    A single solar panel is basically useless. You need a huge field of them per small city, and by the time you do have your huge fields of wind and solar, you then need giant grid batteries, and you still often fall short, which means that to be safe you need to double or triple your solar and wind build out.

    Which is why most solar and wind projects are backed up with methane burning generators.

    Nuclear on the other hand, takes up a tiny fraction of the space and outputs orders of magnitude more power, safer and cleaner than any other form of energy.

    South Korea doesn't have a lot of land mass for solar, they do however have competent engineers and scientists.

    Fun fact, most of the fearmongering around nuclear has been paid for by oil companies, starting with Hermann J. Muller working for the Rockefeller Foundation, to Robert O. Anderson, CEO of ARCO giving $200K to a man to start an anti-nuclear environmentalist organization called Friends of the Earth. The Rockefeller Foundation directly funded Greenpeace up until just a few years ago.

    As for Fusion, yeah, we can sustain a reaction by feeding energy in, and sometimes, we can observe more energy out than in, but we have absolutely zero ways to capture that energy.

    It doesn't.

    Fusion isn't as bad as fission or fossil fuel. If they can get it to work. The reactor needs to run continuously (for days) and the energy output needs to be positive. Then it would have a huge impact.

    Every energy source as its drawbacks. I.e. Solar panels and wind have the recycling of compound materials issue - it's all glued together. And the environmental impact of source materials production, i.e. neodymium. Mining, refining,...

    Some are worse than others. But none is or will be impact free in terms of sustainability or environmental destruction.

    (Not my field. The following is armchair speculation.)

    Why is [fusion] more economical than [solar/wind]

    TLDR — It’s not. For distributed/residential, bulk power generation, and light-duty transportation, solar has already won so decisively that fusion is not likely to catch up this century. But those aren’t usually the target applications.

    TMK, Fusion offers most of the known advantages of fission (smaller footprint, superior energy density + capacity, output that’s weather-independent and geography-agnostic, etc.) but with significantly better safety and waste profiles.

    Its versatility as a thermal source enables many industrial applications requiring temperatures difficult or impossible to achieve via electrification alone.

    The reaction itself is directly applicable to neutron production.

    There’s some even more far flung applications like outer planetary and deepspace space travel.

    And others. All to say, it’s for niche and future applications PV can’t touch.

    The obvious advantages would be less land use, great for smaller nations, and on demand power without the need to build back-up batteries.

    Plus those are the immediate benefits who knows what we could do with that level of power generation. Maybe we could even make better space craft if the technology advances enough

    Wow it's pretty cool that it can maintain magnetic confinement with that giant window cut out of the containment vessel.

    I'm not sure that lab coats and hard hats will protect against the x-ray black-body radiation though.

    Isn't the Times of India not reputable? I seem to recall some shady shit from them, including I think Russian sponsored anti vaccine propaganda aimed at poor countries.

    Currently we still don't know whether it's possible to generate more power than you need to maintain the fusion.

    ITER is the European project that should test that. It still is an experimental reactor and won't generate power.

    Several other reactors are currently being built, but only recently they started building ones that in theory could run for a longer time than a few minutes.

    But nobody knows if it will be useful.
