“This is Zu° Rack v1 — fits between two server racks, drinks 100 % of a 40–50 kW rack’s waste heat, spits out chilled 18 °C water back to the CRAC loop and pulls 1.8 L pure O₂ + 2.2 kg dry algae biomass per day.
Revenue math on one rack (conservative):
Algal oil → 0.55 kg/day × $55/kg (omega-3 grade) = $11,000/yr
Carbon credits → 9 tons CO₂e avoided/yr × $120/ton = $1,080/yr
Heat credit (if xAI pays for cooling) → 400 MWh/yr avoided chillers × $60/MWh = $24,000/yr
Total gross revenue per rack: ~$36–45k/yr
Hardware + install cost: $38–42k
Payback: 11–13 months (or <8 months if xAI buys the cooling service).
200-rack pilot = $7–9 M/yr revenue, $8 M CapEx, fully paid back before Grok 5 finishes training.

Scaling closed-loop algae bioreactors for xAI Colossus.
1 GW waste heat → high-value oil, slashed cooling loads, pure profit, and Scope 1 neutrality.
Pilot-ready. Turnkey. Ready when they are.
Jack of all trades. Thing king of contained ecosystems.
Thanks for playing.
