Planet 2048-d
Federated aggregation over open Earth foundation models — Aurora, Prithvi-WxC, GraphCast, GenCast.
Global summary
Redesigning the relationship between production and place.
From observation to action, at community speed.
Earth already has eyes on it — Copernicus, Earth Engine, Aurora, GraphCast. What it doesn’t have is the wire between those eyes and a network that can actually respond. PLANETAI is an instrument for closing that loop: community-scale sensing, bioregional decision, distributed fabrication response — in days-to-months, not years-to-decades.

The gap
Observation-rich.
Action-poor.
A satellite pass tells a European ministry that PM2.5 in a valley crossed a threshold in March. The ministry feeds it into a policy cycle that reports in 2028, legislates in 2030, permits retrofits in 2032, and measures impact in 2035.
The observation was excellent. The response took a decade. During that decade the valley kept breathing the same air.
Existing Earth observation is calibrated to intergovernmental treaties. PLANETAI is built for the opposite loop.
PLANETAI’s nodes are also a way to protect distributed public capacity for observation, science, citizenship and policy when the centralised version is fragile.

The instrument
A five-tier open AI stack,
bound to a standing network.
Each tier is simultaneously a computational layer, a governance layer, a data layer, and a fabrication-and-deployment layer. Dimensionality descends from planetary foundation models to on-device inference. Why these five? One test: each is a stratum where an observation can reach a decision body the network can put a proposal in front of, and the approved response can be fabricated inside the network — where the loop closes, and can be timed.

Fab Lab node
The node
PLANETAI is infrastructure, not an app.
The stack compiles to hardware. Node #1 is running.
The observatory you see is the cloud face of a deployable node — a small open-hardware box that lives at a fab lab and ingests planetary models, bioregional data, and its own community’s sensor feed. One node per pilot; the first has been running in Bali since September 2026. On each node, a narrow set of action agents drafts measured responses into a queue — a named human approves or rejects before anything fires.
Live · node #1 · since 2 September 2026
A node is running in Bali. It sees one house from the kitchen to orbit.
Node #1 sits in Kuta Selatan reading four sensors that were already in the house, the island’s public network, a radio gateway for sensors with no WiFi, and overhead the Copernicus atmosphere model, the ocean model, Earth Engine’s view of the land and Google’s open building footprints. It decides where it stands, tells the household what to do in plain sentences on Telegram, answers their questions through a small model on its own machine, and records whether anyone acted: ρ, the Index’s action-latency term, measured for the first time. In its first week: two of every three alerts led to someone doing something.

PLANETAI Node v0 · Open hardware
A federated-data node at the fab lab, not a datacentre.
The node runs the Region, City, and Community tiers as a storage-rich, asynchronous compute layer. It retains local data, caches what the bioregion needs, and pairs upstream Earth-foundation embeddings with locally-curated observations. Federated by design — one node per pilot, four nodes ship.
- Compute
- Compact general-purpose node · storage-rich · optimised for asynchronous federated workflows, not latency-sensitive edge inference · spec'd in the hardware annex
- Sensors
- Campaign sensor kit · environmental HAT · pilot-specific add-ons · deployed per campaign, not as continuous fleet
- Licensing
- Apache 2.0 / CERN-OHL · OSHWA-track certification
What the node does. Federated data retention, raster and sensor cache, model checkpoints, Region / City / Community-tier feature extraction, periodic model updates. Aurora and GraphCast run upstream at bioregion-server scale; the node consumes their embeddings and pairs them with locally-curated data.
Action agents · Human-in-the-loop
Four narrow agents, one per pilot.
Agents are constrained — each runs a single bioregion-specific workflow. They draft, they never dispatch. Every draft → approve → deploy cycle writes to a public audit ledger, timestamped against the action-latency hypothesis.
-
A1
Bali · Agent-1Wet-season + burning-trash air quality. Campaign-deployed kits + community reports + IQAir community feeds → drafts a ventilation / respirator-kit dispatch for Fab Lab Bali & CAST partners.
-
A2
Barcelona · Agent-2Circular-flow template scheduler. Fab Lab BCN waste-to-production loop → drafts weekly reuse / remanufacture tickets against the OSH/OKH library.
-
A3
Santiago · Agent-3Informal-economy visibility probe. Bridges the ~75% ECI blind spot — drafts survey sweeps and sensor-deploy tickets for Núcleo Milenio FAIR.
-
A4
Boston · Agent-4Community sensor QA + calibration. MIT CBA fleet → drafts calibration-run schedules and flags drift against co-located reference stations.
Not autonomous. Every action queued by an agent requires a named human approver at the fab lab. Governance is enforced at the bioregion-server boundary, not at the agent.
Two claims, on trial
Two pre-registered falsifiable hypotheses.
Positive or null, both will be published.
H0−T · Throughput (null)
Does distributed production lower urban material throughput?
Null: distributed production at community and city tiers does not causally reduce urban material throughput or energy demand by more than 15% over 36 months, measured against a synthetic control baseline.
Three outcomes, all publishable. Strong positive (40–60%, LCAs suggest), partial positive (15–20%), or null. The in-window test is at community/district scale; bioregional H0–T is a designed follow-up deliverable on month 60+ data when statistical lag and power both improve. A null at this scale would itself be a first.
H0−A · Action-latency (null)
Does coupling observation to the network shorten response time?
Null: coupling multimodal observation to the Fab Lab network does not measurably shorten observation-to-action cycle time, relative to a policy-only baseline anchored on three completed Fab City Challenge editions (Bali 2022, Bhutan 2023, Mexico 2024; 12–16 weeks brief-to-prototype), across 4 community hubs (one per pilot) using difference-in-differences estimators.
Measurement. Five timestamped stages: detect → decide → fabricate → deploy → measure.

The instrument
is open
The leverage isn’t building a new network — the network exists. It’s the coupling that turns it into an instrument.
The monitoring case is in the literature: Balestrini, Diez et al. (EAI Trans. IoT, 2015) — a 15-month SmartCitizen deployment study across two communities — find local-champion orchestration is the determinant of sustained participatory sensing; Chen, González et al. (Atmospheric Pollution Research, 2025) show low-cost sensors deployed via fab-lab institutional support meet US EPA performance targets at R² > 0.7, RMSE < 5 µg/m³. The action case is also documented: Thomas (2023, ADB ex-ante BCA / Zenodo) projects $5–12 BCR for the 2023 Fab Bhutan Challenge through 2033.
Four bioregions
Calibrate once. Export honestly.
Falsify across climates.
Each bioregion discloses what exists and what’s being built. We do not flatten them into identical templates; instrumentation reality differs, and saying so matters more than a clean card grid.

What we’re honest about
Disclosures, upfront.
The observatory tags every value with provenance — LIVE, CACHED, SYNTHETIC, PENDING. The research programme holds itself to the same standard.
-
Connector pending
Cross-network sensor normalisation is not solved. It is a research deliverable of this proposal, not a completed primitive.
-
Synthetic proxy
Bali has no Metroverse City-tier ECI. We reconstruct the City-tier signal from Bali Satu Data (provincial open data, 4,700+ datasets, Tri Hita Karana taxonomy) feeding the same PITO/DIDO/ρ framework every other pilot uses — no Bali-specific index. Engineering ingests via data.go.id (CKAN 3.0 national portal) plus a Bali Satu Data scraper; partner collaboration with Diskominfos is year-one work.
-
Calibration required
Community sensors carry ±30–80% uncertainty against reference instruments (Castell et al. 2017); ≥30-day colocation is the required calibration protocol before any reading enters the bioregional index.
-
Commitment
We have committed to publishing null results if either hypothesis fails to reject. The pre-registration is the instrument’s own peer review.
