The heart of the Hansa coking plant is its impressive machine hall.

There, like coffins, round steel boilers are arranged next to each other, in the openings of which pleul bars rest. These may have driven the huge flywheels, which are located next to each of them. Many openings are provided with lids. Flanges are screwed with gigantic screws. There are drains, inflows, rotary wheels, metal hoses.

Or is it all something completely different? I'm not sure if these forms are material from the past or the future. Alien I sends greetings if you will.
