    You put it in a hole, done. Humanity is capable of that, for sure

    Looking at the discussion where this hole should be doesn’t give me confidence. Everyone wants long term storage, but no one wants it near themselves.

    We’re producing nuclear waste for half a century and there’s still no long term storage location. The generation who created this early waste is currently dying away and I don’t think the generation after wants to deal with the problem either.


  • Not everything is about economics, otherwise we probably wouldn’t be talking about renewables at all.

    Taking the long term impact of coal, gas and oil on our climate and nature into account, renewables are cheaper. The cost of destroyed infrastructure through (ever more likely) extreme weather events alone is immense and often not taken into account, not to mention the impact on food.

    The amount of money countries have is limited. If the goal is to replace coal, gas and oil as quickly as possible it’s more efficient to use cheaper technology.

    As for “free energy”, no energy is free.

    Yes, my point was about already built solar and wind turbines, that lose money the moment they are not running. The same is true for a powered down nuclear reactor, as the fuel isn’t the expensive part of the operation.
    My point is that technology that is expensive even if not curently in use, does not make for good backup power. This makes renewables and nuclear not a good combination, as it’s quite expensive.

    Biomass isn’t practical as it releases far too much emissions to be worth it, you almost might as well use gas.

    Yes, biogass is only an option as an addition and shouldn’t be used continuously (for backup power it should be fine).

    This is especially true for Thorium technology or actinide burners. Actinide burners literally reuse nuclear waste.

    Those are future technologies never used commercially (if at all). Thorium reactors are not even in the testing stage yet, it’s even worse if you look at acinide burners. I’d like to switch to low emission energy now, not in a few decades.





  • People arguing against nuclear power for it’s cost and unclear timeline usually don’t argue for coal, oil and gas.
    Wind and solar are cheaper, continue to get cheaper and can be built within years, not decades.

    Also, renewables are a proven technology while proposals for new nuclear reactor tech have usually never been deployed successfully (as in running continuously and actually contributing to the grid).

    No one is suggesting Nuclear as the only source of energy. It is very helpful though for grid firming and reducing the amount of expensive and environmentally destructive energy storage therefore reducing the overall cost of operating the grid while increasing reliability and reducing land usage and environmental damage.

    Nuclear reactors are not useful for grid firming in a renewable grid, because they have to be running at 100℅ all the time to be anywhere near economical.

    Renewables (wind-/solar) aren’t the most predictable sources of energy, so they need something to jump in when power demand is higher than supply. Nuclear reactors can’t deliver on that use case, while battery-storage, pump storage, biomass etc. can.

    This means a grid with 30℅ nuclear would have to stop wind turbines and solar panels (free energy, since they are already built) instead of powering down more costly biomass. This results in more expensive renewables (as they aren’t used to their full capacity).


  • SteamOS as a whole is not open source. Most of it is, but it also includes proprietary software (e.g. Steam itself). This is likely why you were downvoted, as SteamOS can be kept private without violating any license thus your first statement was false.

    Valve could distribute each single piece of open source software they use on request to their customers, without publishing any guide to actually build it. (Thanks for linking to Valve’s repo, which seems to match this statement.)

    This is how Apple does it with Darwin, the BSD-derived open source core of macOS. Without all the proprietary parts it’s not useful as an OS, even though they follow all the necessary licensing.






  • Podman provides stronger isolation than nixos-containers because the latter only supports rootful containers. Losing access to nixos modules is a disadvantage, altough most services I’d use podman containers for don’t have any modules anyway.

    E.g. I’ve used nixos container as a stop gap to use a major beta, because I didn’t manage to adapt the nixos package accordingly.
