Water
No industrial water cooling disclosed. Quantum processors on site (Ocelot cat-qubit chip) operate in dilution refrigerators at near-absolute-zero temperatures, which use closed-cycle helium (helium-3/helium-4) rather than facility water for cryogenic cooling.

The California (CAISO) grid demand right now: 25.0 GW (EIA-930, 2026-11-07 17:00).

County water status: Abnormally dry (D0) in Los Angeles County, week of 2026-11-03 (US Drought Monitor). Data centers are large water users for cooling; this is the neutral local water picture.
