    in a situation in which harm increase over time, like the rise of far right, anti-science, environmental damage, etc… perhaps that “wait” is a less ethical solution than to solve the problem

    now, perhaps causing harm isn’t the way to go, but… the lesser of 2 evils may still be somewhat problematic







  • the case for grid-scale batteries is getting stronger every month:

    the more people driving EVs the more used EV batteries will become available… EVs require a pretty good energy density, but grid storage can buy up a bunch of dirt cheap EV batteries with 60% capacity and call it a day, and then onsell them for recycling in 10 years for exactly the same price (because the raw materials are the same: recyclers don’t care if the battery has 100% or 60% or 50% max capacity)

    other battery tech is also getting much more interesting, like sodium batteries. they don’t have the energy density of lithium, but they’re more durable and have less fire risk. they’re pretty ideal for grid-scale storage, and when commodities of scale kick in with them they’re likely to become pretty common in grid storage and prices and usefulness just gets better from there

    also, afaik gravity batteries aren’t really being used… the most common thing these days looks like it’s going to be flywheels, but using them more like capacitors: smoothing out load spikes and maintaining grid frequency (which with PV can go downhill fast)


  • i agree with the anti-nuclear, but the mining conditions are really far less of a problem with uranium… canada and australia are #2 and #4 in the world respectively

    uranium is relatively plentiful, and hugely energy-dense so most places have some that’s viable to extract, and it’s not worth cheaping out on costs to save a couple of $ buying from slave mines given the potential backlash

    i actually wouldn’t be surprised if uranium mining is one of the best jobs in the developing world because if they actually want to sell their product they’d have to market their working conditions


  • nuclear costs a shit load of money up front and has such massive NIMBY pushback… it’s great for the fossil fuel industry to argue for because it’s politically impossible to actually implement: we need more nuclear! stop with all the renewables! leads to only 1 thing… talk about nuclear and no more renewables

    meanwhile, batteries really don’t produce much environmental damage… that’s just straight up misinformation… and the bonus with batteries is nice the materielsd are mined, you can recycle them back to brand new forever… you don’t have to keep mining all the lithium; just enough to keep up with new capacity








  • sewer systems aren’t air tight either - they need to let gasses escape, so i think even without an airtight seal if we consider a sewer in general a pipe system of this category it’s fair to consider the connection between butt and toilet also part of this system

    many people have a special wireless connection, which explains the sewage that spews from their mouth
