Water Balance — TriArk vs. the Feared Machine

The 1–5 million gal/day fear is real — for evaporative-cooling data centers. That's one cheap cooling choice, not physics. ArkLight consumes ≈none and manufactures water. Every figure traces to a row.

◤ THE FEARED MACHINE — evaporative cooling

−1M to −5M

gal/day consumed, zero produced. Cooling towers boil water to the sky to shed heat.

◢ ARKLIGHT TRIARK — one 45 MW cell

+90k to +120k

gal/day produced, ≈zero consumed. Closed-loop, dry-cooled. The burn makes the water.

1 · Closed-loop, dry-cooledCooling water circulates. Nothing evaporates. Consumption ≈ 0.

2 · Cooling is free heatTrigeneration — turbine exhaust drives absorption chillers. No towers, no compressor load.

3 · Combustion makes waterCH₄ + 2O₂ → CO₂ + 2H₂O. The reaction itself yields water.

TRACED ROWS — every number, its derivation
FIGURE	VALUE	HOW IT'S DERIVED
Water per lb methane	2.25 lb	36 g (2×H₂O) ÷ 16 g (CH₄) = 2.25. Exact.
Water per MMBtu gas	~11.7 gal	2.25 lb ÷ 8.34 lb/gal ÷ ~23,000 BTU/lb
45 MW cell burn	315–415 MMBtu/hr	heat rate 7,000–9,200 BTU/kWh (recuperated aeroderivative)
Gross combustion water	90k–125k gal/day	11.7 × (315…415) MMBtu/hr × 24 hr
Site consumption	≈ 0	closed-loop dry-cool — nothing evaporates

NET WATER HANDED TO THE TOWN — live

⚠ THE ONE OPEN ROW — flue-gas condensate recovery % · UNSEALED until Skippy's study lands

Currently written as "the majority" — the last adjective, the exact spot an engineer jabs. Set the number.

0%recovery fraction100%

NET =—gal/day handed over · recovery 60%

NET = gross combustion water × recovery − site consumption (≈0). Stated as net, not gross. Flue condensate runs slightly acidic — treated / polished before hand-off.

The honest sentence: The feared machine consumes millions of gallons and produces none; ours consumes ≈none and produces tens of thousands of gallons a day. Different architecture — not magic math.
