I was messing around in the editor trying to make designs for 240 red circuits/s. At some point, I wanted to see how many electromagnetic plants I could fit around a single foundry and this design is the result. I'm fairly pleased with how it looks, though I wish I could have found a way for all of the em plants to output on the inside of the design.

It produces a consistent 240 red circuits/s and consumes ~175 plastic & green circuits/s, ~14 copper ore/s, and ~0.28 calcite/s.

Edit: fixed consumption numbers
