This is of course not meant as a serious design, though I am surprised by how well it works.
Every 60 seconds, a Prod 3 module gets recycled (1) into a fresh biter egg with a 30 minute spoil timer, which gets placed on the waiting belt (2). Shortly before it spoils, it gets placed into the biter holding area (3), where a biter then hatches and is summarily executed by the railgun (4), taking the contents of the trash-chests with it to the afterlife.
The Railgun Ammo and the Prod 3 Modules are made on Nauvis and shipped to Fulgora.
Due to Mining Productivity 1k and the magic of putting Tanks with Toolbelts on belts, a single Big Mining Drill is sufficient to supply my 100k SPM Fulgora base.
The design is quite tilable, with each of the modules producing 10k SPM.
The production of the base is remarkably stable and it manages that without a single unsorted belt or Logistic Robot.
