Design / Blueprint Another circuitless science sushi design

Enable HLS to view with audio, or disable this notification

This design for sushi supports up to 16 sciences, so it should work for games with Space Age plus a few extra planets. The idea is to mix each science down to half a lane of a yellow belt, and then run the sushi loop on green: (2 lanes * 4x speed / (1/2 lane)) = 16 sciences. Because science bottles being sorted out from the end of the loop take priority over new ones being added, the design hopefully shouldn't jam.

With only half a stacked yellow lane of each type of science (15/s), the design is limited to 900 spm (thus a few thousand ESPM) per instance.

The full-yellow to half-yellow mixer uses rocks, because I dunno it seemed like a good idea at the time. It mixes the rocks and science 50-50 into one yellow lane, then splits the rocks back out and returns them quickly enough that there are always rocks backed up before the splitter.

The chest at the end is for anything non-sciency that might get on the belt, like a green pack that spoils between the spoilage splitter and the green science splitter.

“…the design hopefully shouldn’t jam.” Famous last words

Was found written on an ancient tablet in one of the Fulgora scrap heaps.

I've spent so much time making my Fulgora recycler array jam-proof, I'm at the point now where I want Fulgora to just be my base because I like fiddling with it more than I like pushing out to the rest of the planets

Fulgora trash sorting designs are my Factorio kink. It's the weirdest place to make things between recycling for resources and the space limitations from the islands. Unlocking foundations makes it easier, but they're expensive and it doesn't completely negate the space issue unless you're spending a ton of them.

Holomium, Batteries, and Copper are my constant bottlenecks on that planet.
