  • The scale of what you just described is really goofy.

    The word you’re looking for is “big”. As in, it embiggens the noblest spirit.

    I don’t think it’s feasible to protect a mars-diameter disc of massive magnets from damage by either normal objects traveling through the area or from some human engineered attack.

    It’s also not possible to protect the ISS from either of those and yet it’s operated fine for 30 years. You do not need every little bit of it to be perfect, you just need to deflect enough solar wind that it allows Mars atmosphere to build back up which is what provides the real protection.

    If you’re imagining the capacity to create such an emplacement, don’t you imagine that such phenomenal effort and wealth of resources would be better spent solving some terrestrial problem?

    Like I said, we waste more resources than that all the time. I’d rather we didn’t build yachts and country clubs and private schools, yet we do. There’s no reason to not get started building that array, especially if it will take a while.

    There’s a real difference between e-waste, which is mostly byproducts of the petroleum refining process with electronic components smeared liberally on, many of which rely on petroleum byproducts themselves and electromagnets, which are, at the scale you’re discussing, massive chunks of metals refined, shaped and organized into configurations that will create magnetic fields when dc is present.

    That is not what e-waste is. E-waste primarily consists of silicon chips and the metal wires connecting them. Even the circuit boards themselves are primarily fibre glass, not petroleum.

    And no, we wouldn’t be creating those using actual magnets, we’d be using electro magnets, which is just coils of wire connected to PV and logic chips.

    I quite frankly flat out do not understand why people on the left are so against space exploration suddenly. You know that Elon Musk is not the only billionaire right? And you know virtually that all of them just sit on their wealth, and do nothing with it but wast on luxury lifestyles for themselves right? Yeah it would be better if billionaire’s did not exist, but as long as they do, why are you upset about their money going to space exploration as opposed to just yachts and $20,000 a night hotel stays?






  • This is a pretty embarassing way to open this article:

    Mars does not have a magnetosphere. Any discussion of humans ever settling the red planet can stop right there, but of course it never does. Do you have a low-cost plan for, uh, creating a gigantic active dynamo at Mars’s dead core? No? Well. It’s fine. I’m sure you have some other workable, sustainable plan for shielding live Mars inhabitants from deadly solar and cosmic radiation, forever. No? Huh. Well then let’s discuss something else equally realistic, like your plan to build a condo complex in Middle Earth.

    NASA legitimately has a plan for this, and no it’s not crazy, and no it doesn’t involve restarting the core of a planet:

    https://phys.org/news/2017-03-nasa-magnetic-shield-mars-atmosphere.html

    You just put a giant magnet in space at Mars’ L1 Lagrange point (the orbital point that is stable between Mars and the sun), and then it will block the solar wind that strips Mars’ atmosphere.

    Otherwise cosmic rays etc are blocked and interrupted by the atmosphere, not the magnetosphere.

    The confident dismissiveness of the author’s tone on a subject that they are (clearly) not an expert in, let alone took the time to google, says all you really need to know about how much you should listen to them.



  • This is a trash article.

    Here’s the Reuters article: https://www.reuters.com/business/autos-transportation/maersk-agrees-study-nuclear-powered-container-shipping-2024-08-15/

    It makes it clear that Maersk has joined a study being lead by Lloyds Register and Core Power to assess the potential of using 4th generation nuclear reactors on cargo ships.

    A couple of demonstration nuclear powered commercial ships have been built in the past (by the US, Japan, & Germany), but they’ve all been too expensive to operate commercially and have all been retired or converted to diesel, mostly due to being too complicated to maintain and repair, and too specialized to benefit from any economies of scale.

    The US Navy and France both currently operate nuclear powered aircraft carriers, the US, UK, Russia, France, India, and China all operate nuclear powered submarines, and Russia has a bunch of different nuclear powered military ships and icebreakers so it’s not a radical concept, and I have no idea where the linked article is getting the “only 4 have ever been built” claim.

    Lloyds Register has also been running these studies for years, the only real interesting tidbit here is that Maersk is interested and they’re big enough to move the needle singlehandedly, but again they’re just signing up to participate in an early high level assessment of the idea, the assessment could just say ‘nah, not worth it’ and this is just a non story.

    • Other store brands

    All of them will get you a passing grade, C Tier feels a little flimsy like it might let you down, B Tier works perfectly fine and feels normal, A Tier feels like it could take one extra hard drop, and S Tier is noticeably rock solid and nice in every way.

    Atleast, this is ballpark what I remember from when I was contracting…

    Training and running them consumes enormous amounts of energy,

    Right now, using GPUs and unoptimized chips. Running and building other services like Google Search and YouTube also took enormous amounts of power and still does, though it’s vastly more efficient these days.

    all the IP is within some gigantic monopolistic corporations,

    This feels like a pretty knee jerk point instead of a well thought out one.

    A) the biggest AI players are startups like ChatGPT and Anthropic which have gotten a lot of funding and attention but are neither giant nor monopolistic.

    B) of the biggest monopolist companies (Apple, Google, Microsoft, and Meta), only Google and Apple are keeping their research closed, with both Microsoft and Meta publishing their models openly.

    these corporations in turn push huge amounts of money into products that are not only bad, but dangerous (MS Recall or X’s porn generator AI),

    Literally the vast majority of software developers already use copilot or a similar AI assistant. Bing search is genuinely useful for synthesizing answers and asking plain language questions with sourced answers. People are finding ChatGPT useful or they wouldnt be paying for it. DeepMind has literally discovered novel protein structures that we never knew existed before. And VFX artists like Corridor Crew are using it to make wild videos way faster than they ever were able to before. This feels like youre just cherry picking poor uses.

    other corporations use AI as excuses to fire thousands of people and letting their core products rot away.

    Capitalism does that with all forms of automation, whether it’s AI based, or just normal, run of the mill, software / machines. It’s how you end up producing the same products with less effort and manual labour. If you want to go back to hand milling flour you’re more than welcome to, otherwise automation is going to continue. The answer to automation lies in the government and social safety nets, not blocking automation technology.


  • We already have a way for society to decide what is and isn’t worth spending power and effort on and it’s called money.

    Increase carbon taxes to incentivize clean fuel sources and ban predatory advertising and data tracking behaviour because it’s problematic.

    We do not need to setup a separate shadow economy to gatekeep what is and isn’t worth spending eoectricity on.


  • AI search is legitimately useful.

    For something like Salesforce development, you’ve got the answer spread across their old framework docs, their new framework docs, their config settings reference page, and a couple stack overflow questions.

    Copilot / Bing search has legitimately been incredibly helpful at synthesizing answers from those and providing sources so that I can verify, do more research, and ask follow up questions.

    Like I get what you’re saying but this is also hysterical to the point that people are going to ignore you.

    Don’t use AI ever if there are consequences? Like I can’t use an AI image search to get rough ideas of what the plant might be as a jumping off point into more thorough research? Don’t rely solely on AI, sure, but it can be part of the process.
