  • Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.

    Recycling nuclear waste is one of those problems that should be easy but nobody knows what the easy way looks like. It’s impossible to tell if some breakthrough will make it viable tomorrow or if people will have to work for 200 years to get to it. But yeah, currently it’s best described as “impossible”.

    Energy density is a useless bullshit metric for stationary power.

    Produces more waste than almost all of the renewables.

    Reliable compared to… … … ok, I’m out of ideas, they need shutdowns all the time. Seems to me it’s less reliable than anything that isn’t considered “experimental”.

    And it can’t work with renewables unless you add lots and lots of batteries. Any amount of renewables you build just makes nuclear more expensive.

    They are an interesting technology, and I’m sure they have more uses than making nuclear weapons. It’s just that everybody focus on that one use, and whatever other uses they have, mainstream grid-electricity generation is not it.









  • It is just the most active posts.

    If there is a whoosh moment, it’s this one. But technically, no, I browse by “new”, and that’s what I subscribe to.

    About You Tube, yep, it can change in a whim just by clicking on the wrong video and watching the few seconds it takes to discover it’s some crazy piece of shit. Anyway, there’s fun stuff there.
