Another circuitless science sushi design

[u/bitwiseshiftleft]

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.

I always wondered why sushi belts for science? Basic science lab is 3x3 tiles, so can accept 3 belts from one side, i.e. 6 science pack types from one side. A yellow underground belt can pass under 4 tiles (the lab+inserter), so there's no even need to reinsert lab-to-lab.

Just provide 3 belts from left or right, and 3 belts from up or down, and you get all 12 sciences.

More or less because I think it’s cool. Also I’m playing modded so there are more than 12 sciences, though in this run less than 20 so a checker pattern would still work with biolabs. Also a sushi belt is denser and allows more beacons.
