Distributed infrastructure

Distributed AI infrastructure that reuses waste heat.

Cloud Wash Laundry converts compatible laundries, vehicle wash sites and related facilities into resilient micro data centers with useful thermal loads, water-efficiency systems and local business benefits. Its central network objective is to prove that these sites can be linked over dedicated dark fibre with NVIDIA Spectrum-XGS scale-across networking strongly enough that the mega data centre is no longer the default way to build AI infrastructure.

The business model combines distributed computing, useful heat recovery, water efficiency, real-world service revenue and scalable site economics.

What makes the model different?

It pairs edge compute with facilities that already benefit from heat, hot-water demand, real estate, parking, utilities and local customer traffic.

Why micro data centers?

Shorter physical distance supports lower latency, while distributed siting helps with redundancy, continuity and flexible deployment across many jurisdictions.

Layered economics

Parent-company royalties, franchisee cash flow, utility savings, service revenue and site ownership create several complementary income streams.

Why conventional data centres face resistance

The public sees the water, power, land and waste-heat problem.

Large centralized data centres can concentrate electricity demand, cooling-water demand, land use and rejected heat in one place. Cloud Wash is designed around the opposite proposition: distribute compute into compatible existing businesses, recover useful heat first, and use water only where it materially improves rejection.

Water

The current Los Angeles screening model uses 74 m³/year of direct evaporative water in its central case. A dry-only captured-loop sensitivity uses zero direct cooling water, while a 0.6× rated-IT hybrid cooler rejects all captured heat with at most 217 m³/year of recycled host water in the screened cases.

Useful heat instead of waste heat

Under the optimistic fully temperature-compatible bound, 50.38 GWh/year becomes useful process heat: 79.4% of IT electricity and 93.4% of modeled host thermal demand. Lower temperature compatibility materially reduces that benefit.

Existing sites, not giant greenfield campuses

Car washes and laundromats already have recurring thermal demand. The current model treats that demand as the siting and capacity constraint rather than assuming arbitrary compute density can be accommodated.

Heat-sink-constrained siting of distributed AI infrastructure: energy, carbon and water impacts in Los Angeles

The current deterministic hourly study places 6,160 B300-equivalent accelerators across 120 representative car-wash and laundromat hosts and tests useful heat, carbon, water, climate and metropolitan-network constraints. Its network programme uses NVIDIA Spectrum-XGS as the scale-across layer over dedicated optical fibre and specifies fibre-spool and multi-site experiments to test whether distributed sites can match co-located clusters — the key experiment behind the project’s objective of proving that mega data centres can become obsolete as the default architecture for many workloads.

Mechanism-resolved modeling and adaptive control of a fanless photovoltaic-thermal heat-rejection array

The current 170 m² roof-array study resolves passive and wetted mechanisms separately, quantifies the water-capacity trade-off, rejects array-wide ionic wind on energetic grounds and tests roof-area matching from micro facilities to hyperscale.

Central architecture challenge

The goal: prove the mega data centre is no longer necessary.

Cloud Wash Laundry is being designed around a direct technical challenge to the conventional mega-campus model: place compute where useful heat already exists, then connect those heat-sink-sited AI factories with dedicated dark fibre and NVIDIA Spectrum-XGS scale-across networking so the distributed sites can operate as one metropolitan compute fabric.

The dark fibre is the dedicated optical transport; Spectrum-XGS is NVIDIA’s scale-across networking layer. The project’s proposed fibre-spool testbed and multi-site field pilot are intended to determine whether distributed sites can match co-located clusters on workload-level measures such as time-to-result and energy per token.

Latest physical-model findings

Measured next. Modeled now. Heat-sink constrained.

Current design-stage results combine the 120-host Los Angeles heat-sink-siting model with the updated fanless heat-rejection screening figure. They are screening outputs, not field-certified performance. In parallel, the network programme tests whether NVIDIA Spectrum-XGS scale-across networking over dedicated dark fibre can make geographically separated AI factories behave as one compute system. The mega-data-centre conclusion remains an experimental objective, not an already validated result.

The 79.4% and 77.6% values use the optimistic fT = 1.00 temperature-compatibility bound; lower compatible heat fractions materially reduce both benefits. The updated fanless heat-rejection figure also summarizes 83 of 144 states as feasible overall and 77 of 144 as feasible by free pathways alone, while array-wide EHD is not preferred because only 3 of 80 tested cases exceed the conservative comparator.
