"50 wires inside the permiter of 2 scrubbers at maximum power, though current thinking seems to indicate that lower powers will lead to more efficient generator setups. See https://gtm.steamproxy.vip/app/464920/discussions/0/1696043806570023086/?ctp=3

Key:
pink - outer bounding wire.
black - scrubbers x 2
blue - wire hexes x 50
stirling generators are white hexes inside pink perimiter."
