  • Combined cycle natural gas plant operator in the US here. Bridging the gap between low demand and high demand times is a big part of why it’s so challenging to try to reduce fossil fuel power solutions. The grid is basically a pressurized pipeline, and it’s only reliable if that pressure is maintained no matter how many “faucets” get opened or closed. Green energy solutions aren’t really able to raise that “pressure” unless we build significantly more than we need and keep a bunch of them off most of the time until peak conditions demand them. Nuclear is extremely slow (relatively speaking) to (safely) alter output to meet demand, so its best usecase is for baseloading as much as possible. But with a natural gas plant, I can put my foot on the gas pedal, figuratively speaking. It’s fucking terrible for the environment, but that’s the cost of everybody insisting on consuming so much goddamn electricity all the time. If you don’t like it, stop supporting power hogs like data centers by using AI bullshit and cloud storage and web hosting and media streaming.

    This is a complicated problem, and complicated problems almost never have simple solutions. I wish we could minimize the problem of what happens when 100M+ EVs get plugged in at 7pm on a Tuesday by already having put together a strong public transportation infrastructure that people feel comfortable and safe using, but the time to start doing that was probably during the gas shortage in the 70s when we saw how overly reliant we were on cars. It’s probably not too late to start, but it’s gonna be a challenging transition now no matter what we do.





  • I don’t know that I’d call it a song per se, but Brand New did this on The Devil And God Are Raging Inside Me. I think it was like a minute of stuff that seamlessly blends right into the start of Sowing Season. I don’t own the CD and I only heard that part once like 15 years ago, so I truly can’t remember what it was. Maybe like a message on an answering machine?

    Edit: found it



  • Yeah but stupid people are plentiful and overly confident that they can spitball a better idea for solving the problem than literal experts with decades of expertise can because “they’re too close to the problem” or “they’re paid off by big [fill in the blank] to gum up any progress” or whatever. They just don’t believe in complicated solutions or complicated problems because most people aren’t doing anything particularly complicated with their lives. Incurious people aren’t interested in any explanations or nuance.

    In a normal, unsuppressed semiautomatic pistol gunshot, you pull the trigger, a precise little pin strikes the back-center of a bullet, this causes the gunpowder in the back of the bullet to spark and ignite and explode. The projectile portion of the bullet rides the wave of the explosion at supersonic speed down the barrel of the gun, which determines the direction of the path. There is an initial increase of backpressure of gas between the projectile and the back of the barrel, but semiautomatic weapons make use of this to push back the slide, expelling the spent casing and that gas and allowing the spring in the magazine to push the next round into place for the next shot, also significantly reducing recoil in the process.

    Suppressors (or “silencers”) work by slowing the bullet down and altering the propulsion gas path. Subsonic speeds means no sonic boom. The downside is that you must manually cycle each round yourself, and you will likely experience more recoil per shot.

    Afaik, suppressors are pretty damn hard to legally obtain, so my knowledge of them is a combination of my firsthand accounts with my unsuppressed guns, secondhand accounts of suppressors, a moderate understanding of physics, and some guesswork. I could be wrong about some of this, but this is my general understanding that I carry around with me.
