This layout uses extreme belt-fu and belt weaving to create a layout that generates ~58.5 Casimir Crystals per second. Note that due to the extreme hydrogen requirements of the recipe, you will need to have spare slots in other towers on the planet set to Hydrogen on Remote Demand/Local Supply so that the towers in the tile can get Hydrogen by both transports and drones. When built very close to the equator, there two tiny spots on the tile edges that do not have power coverage, but supplying them from adjacent tiles should rarely be problematic. When built closer to the poles (but still in equatorial band), the gaps disappear, but the belts between assemblers are scrunched (but still work fine). Also, since this has ILS at both ends, you will usually have to use a tile with the ILS in the center at one or both ends in order to avoid tower conflicts. Finally, I am using the GroundSubStation mod, but that does not make any functional changes, it just changes the appearance of the Satellite Substations.
