Notes: Moved from chatter. Lead via Compute Atlas and The Data Center Debate. Special use application SU26-22, filed Oct. 30 under Tombstone Resources LLC, describes up to nine computing buildings and about 6,000 MW at full build-out, which would make it the largest data center proposal in Arizona. The application says the campus would be dry-cooled and pump no groundwater for industrial use. The exact relationship between SpaceX and Tombstone Resources has not been explained publicly. The co-op says no power agreement has been reached.
