  • Not if the biggest players buy all their competition and use their multi-state revenue to lobby municipalities to make it illegal to compete with them.

    It’s important to recognize that this is how capitalism works if you try to apply it to natural monopolies such as physical infrastructure, along with anything else subject to inelastic demand, such as healthcare. It’s exactly why it makes no sense to have entities that provide such infrastructure operate according to free markets, because either (1) there will be no competition and the “market” with one seller will abuse their position to maximize profit, or (2) you have competing systems side by side, using double the resources and space (or more) for half the efficiency (or less).

    Too often people think of Capitalism as an efficiency maximizer, when in reality it is a capital concentrator. Infrastructure needs to be efficient in order to best serve the people that use it. We see time and again that energy corporations in the “free market” use their revenue to buy their competitors and lobby for looser restrictions that let them hike rates faster and higher until they’ve completely escaped any semblance of regulation.



  • 1500 kWh per year is effectively nothing. That runs a midrange gaming PC for a few hours. (Edit: I was thinking in Wh, oops) The company won’t even tell you the price up front - the product page just has a link to their contact form - but word elsewhere on the web is that little turbine costs somewhere in the neighborhood of $5500. I don’t know if that’s the price of the off-grid system which includes a battery, or the on-grid system, but I can’t be bothered to email them because it ultimately doesn’t matter.

    In 2023, the Levelized Cost of Electricity (LCOE) for both solar and wind power generation at grid scale were around $50 per Megawatt-hour. That means $5500 spent on one of those methods is expected to yield a total return of about 110 megawatt-hours. If we say the Liam lasts 20 years, never breaks down, is placed in the perfect location where it gets exactly the wind it needs to meet its rated power output (more on that below), you’ll get 1.5 MWh per year or 30 MWh total. If your goal is to spend lots of money to feel like you’re saving the planet, I suppose it’s not a bad product, but if your goal is to actually save the planet, $5500 can go several times farther than this. For that price, I can find kits online rated for 3.28 kW, which even as far north as the state of Maine in the US, will generate about 4 MWh per year, a little over 1/3 the average US home’s electricity consumption.

    Per the graphs on the product page, their turbines also require a very narrow range of wind speeds to even come close to the claims about the power output: 12 m/s, which in 99.9% of the world is a significant gust, but it shuts off entirely at 14 m/s, and the output drops off very rapidly with wind speed. At half its maximum wind speed, it’s outputting 1/8 of its maximum output.

    Contrast these limitations with traditional large wind turbines, which cut-in at around 4 m/s of wind speed (same as the Liam), but can maintain full capacity along a much wider range of wind speeds, typically from around 10 m/s all the way up to 20 m/s. For these turbines, half their maximum windspeed is still maximum power output. It’s a night and day difference in efficiency.

    This mini-turbine is a product with a vanishingly small market. It’s for people who live in very particular locations where solar + battery systems are either so inefficient as to not make financial sense, or their property is occluded for most of the day, yet they also have access to continuous high winds that don’t fluctuate much and average right around this turbine’s sweet spot but no higher. There might be 1000 people in the entire world that this product is well-suited for, and I wouldn’t be surprised if the real number is far fewer. There’s no justification for any article to so enthusiastically say it “destroys” solar panels.

    Edit: Fixed my terrible math and expanded on the costs between this and the current market price of solar systems. My point remains that this is a product for a very niche market, and for most people is not a good value for clean energy generation.




  • I would recommend against pairing Battlemage with a low-spec CPU. As shown by Hardware Canucks, Hardware Unboxed, and others, Intel’s Arc graphics driver overhead is currently much higher than competitors, which means they’re disproportionately affected by having a weaker CPU. This causes the B580 to lose significantly more performance when paired with low-end CPUs than a roughly equivalent Nvidia or AMD card. At the very low end, the difference is especially stark. In some games, the B580 goes from neck-and-neck with a 4060 on a high-end CPU to losing half its performance with a low-end older CPU, while the 4060 only loses about 25%.

    If you’re really stuck with a lower-end CPU, it would be far better to get a used midrange AMD or Nvidia GPU from an older product generation for the same price and use that.

    Have you ever seen Linux Journey? It’s a very informative set of tutorials on how Linux fundamentally works under the hood; all the separate systems that together create an operating system. The concepts you learn there will apply to almost any distro in some way, even if some distros (like Atomic ones) don’t let you mess with all of it.

    For more top-level transition concerns, given that you’re coming from stock Debian running KDE… Bazzite can also run KDE, so provided you select KDE when you download it, your GUI experience should be pretty much identical. Some minor but important differences would include themes, but there are guides for that, too.

    When it comes to package management, the intent on Atomic systems is you basically don’t install traditional packages (Flatpaks are the preferred option), but Bazzite has frameworks in place such that you can install pretty much any package from any distro, as laid out in their documentation I linked in my previous post and just now. Work is also ongoing to make traditional package-based software installations more seamless with an incoming switch from rpm-ostree to bootc, but that’s getting into the weeds. If you have a deb file for a GUI program that’s not available as a Flatpak, you’ll be using a Distrobox to install it.

    If you have any specific concerns about the differences, let me know and I can hopefully give you more details.

    I can highly recommend Bazzite for your needs. It has a KDE version which is clearly your favorite Desktop Environment (DE), it’s extremely safe/stable due to being an Atomic distro (you can always boot into the previous image if a system update broke something), has incredible documentation, supports almost any traditional app through Distrobox (VPN requires rpm-ostree for now), has a scripted easy install of Waydroid for native android emulation, and has a few tweaks preconfigured to ensure the desktop gaming experience is a little more seamless out of the box than a stock distro. It really seems to tick all the boxes for what you’re looking for.

    If you want more focus on development and less on gaming, the Universal Blue team also makes Aurora for more developer-focused workloads, but Steam not being included in the image does introduce some usability regressions - Steam running via Flatpak or Distrobox is just plain less capable than a native install, though work is ongoing to make native installs Just Work even on Atomic systems.

    I agree, investing in a company is fine. It’s when you have the ability to trade your investment without any consequence whatsoever that the madness begins. Investment is supposed to be risky for both the company and the investor! But we’ve managed to externalize that risk into a market in which no single actor can be held responsible when a company is looted and destroyed by greed. Publicly-traded shares are now an entirely tax-free substitute for money - but only for the rich who have turned this system into a game to enrich themselves.





  • 3D-printed shoes could be a great idea given how different everyone’s feet can be. It could save on transportation and logistical costs, and everyone could have shoes perfect for their feet, created much more locally than Vietnam.

    However, the cynic in me says that’s not what Nike is doing, or why - they’re doing this because it lets them cut workers. Traditional shoe manufacturing involves human hands at many process steps, often with machine assistance or other tools. This lets them cut out all of those workers and all of that equipment in favor of one machine that makes an entire generic shoe for them to shove onto shelves next to all the other generic factory-made shoes. This is not the future.


  • Also, the raw material is expected to be quite rare relatively soon.

    To be fair, this wouldn’t be nearly as true if we had persisted with our original plan which was to reprocess the spent fuel, more than 90% of which is still usable material. Once we found a couple huge deposits of Uranium, it became much cheaper to simply mine more of it and dispose of the spent fuel, so the recycling plans were scrapped. Sure, we can technically still pull the spent fuel back out again and recycle it, but we spent many years building reactors without building an equal capacity of reprocessing facilities (which are almost as hard to build safely as reactors), so that ship has more or less sailed.




  • In general, Bazzite being immutable just means the core system isn’t modular to the end user to the degree that Arch is. You of course can use flatpaks or appimages like any distro, and there are still several ways to install traditional rpm/deb/aur programs (the usual Fedora method doesn’t work because dnf doesn’t exist). If it’s just an app that doesn’t require significant integration with the OS, the recommendation is to install them into a distrobox container (where dnf does exist) and then distrobox-export [program] to make them visible to the host system. VPNs need a little more integration so those are installed by layering with rpm-ostree and then enabling the systemd service(s). Layering makes updates take longer to install so it should be avoided when possible.

    One of the interesting things about Universal Blue’s images like Bazzite is if you want the benefits of atomic while also having a more custom system than they offer without having to install a bunch of things in rpm-ostree, the process to build a custom image based on one of theirs is apparently quite easy to do and automate, though I haven’t done it myself.


  • In general, yes. Most of the difficulty is due to being on Linux and running games through the Proton/WINE compatibility layer, so there can be an extra layer of jank involved, but it’s very possible.

    If modding consists of dropping files into the game directory, it will work almost exactly the same as in Windows. However, if some of those files replace the game’s DLLs, then whatever WINE runner you use might need to be told to use the DLLs in the game directory instead of its own.

    If you need to use a mod manager, that situation is still not ideal - native Linux mod managers I know of are only the Nexus Mods app (very new, there’s some talk of it being integrated directly into the Heroic launcher) and Limo. Everything else, you’ll be running whatever bespoke Windows mod manager your game uses through Proton/WINE, probably with Steam Tinker Launch, possibly Lutris.

    tl;dr There can be an extra layer of complexity over modding on Windows, but it’s otherwise comparable.
