          would 190 km of pipe make really dense tangle in a space the size of a small warehouse? the diameter of the pipes seem to be pretty random up to 1m according to the entry

            Yeah I guess the diameter is the key detail. I went on a little rabbit hole with this, feel free to ignore it. TLDR I tried different diameters in the meter-to-cm range mentioned by the article, and the total length varied by a factor of a million.

            First I tried calculating for a fixed diameter throughout.

            If I start with a warehouse volume and a total pipe length, and then work backwards, I get a wide but reasonable pipe diameter. For example, if the warehouse is around 80,000 cubic meters (maybe 100x100x8?), and 40,000 of that is pipe, then the typical pipe diameter is around sqrt(40000 / (π * 190000)) * 2 ≈ 0.52 m wide.

            But the SCP entry says some pipes are as narrow as 2.5 cm. Total length explodes as diameter shrinks. One example is the human body. We have around 100,000 km of blood vessels in our bodies, with a typical diameter of around 0.008 cm and a total volume of around 5 liters (0.005 cubic meters). If we scale 0.005 up to 40,000 cubic meters of pipe in a warehouse, a 1:200 length scaling, the typical diameter would be around 1.6 cm, and the total length would be 200 million km, if SCP 015 is biased toward a lot of little “capillaries.”


            I drank too much caffeine, so next I calculated total length for a distribution of diameters.

            Shit, it wouldn’t be inverse with diameter, it would be inverse with cross-sectional area. I gotta redo this lol


            If the distribution of diameters is inverse, meaning there’s twice as much 10 cm-wide pipe as 20 cm, and twice as much 5 cm as 10 cm, and so on, then we can integrate over diameter, over the stated range of 2.5 cm to 1 m. An inverse curve would have the form y=a/x, where a is a constant, x is diameter, and y is length of pipe at that diameter. If the total length is 190 km, we can set the integral equal to 190 km and then solve for a:

            (hopefully my math isn’t shit)

            Then plug in a to integrate the volume, which is just the product of cross-sectional area π(x/2)^2 and length:

            …So, unless I fucked up my math, which is pretty likely, it actually works out to a somewhat warehouse-sized volume of around 20,000 cubic meters. I don’t know if an inverse distribution is a valid assumption though.

    this shit is just so fucking lazy

    can’t even be bothered to do more then a handful of AI gens

    can’t even be bothered to get some intern to photoshop out the dreamlike reality distortions

    obviously can’t be bothered to hire a digital artist to clean it up

    and definitely can’t be bothered to have two interns put on toolbelts and borrow a wrench and pretend to do some plumbing work in the 2nd floor unisex bathroom (the one with the old sink) and take a few pics with their iphone

    WTF is that lady holding?

    It looks like she’s holding a L Shark Bite fitting but she’s ratcheting it with some kind of wrench? You don’t need a wrench for Shark Bite fittings, they just pop in.

    Also why is there a pipe going into the sink right next to the faucet? Also why are there two copper pipes going out the the corners of the sink fixture? Also why does it look like they have copper pipes going into black pipe elbows? Why are there spools of copper and aluminum wire on top of the sink? Are you plumbers or electricians???

    Maybe someday, you too can be a contractor who gets stiffed trying to help the president embezzle money from the taxpayers in a no-bid contract!

    POV: you’re the government and you have all the money in the world to hire a skilled digital artist to make a campaign poster for your jobs program, but Elon and Lockheed need another 69 billion so you turn to the AI slop machine instead.

    there was a time before stock photos and slop generators where propaganda posters were cool. i hope i see the day that they rediscover this strange entity called the “artist”. maybe then we can get more soviet-style space posters

    two spools of solder wire, no soldering tool, a random wrench, and some pipe mangler looking tool?
