The Node

Standard Node Specification.

AI Compute
1 MW IT load
Immersion-cooled compute rooms within the junction structure. Zero water consumption.
Energy Storage
4 MWh BESS
Co-located battery storage for grid services, arbitrage and priority power.
Capital Cost
≈ €6M per MW
The lowest cost basis of any compute environment: below land, sea or orbit. Zero land acquisition; the junction footprint already exists.
Net Operating Income
€3M per year
IaaS base case across twelve independent revenue streams. Premium layers treated as upside, not relied on.
Design Life
100-year civil asset
The civil structure endures; compute and battery hardware inside is upgraded on normal technology cycles.
Revenue Streams
Twelve, independent
Compute colocation, BESS grid services, EV charging, district heating, carbon, concession, media and further layers detailed on the Investors page.
Compact Node
125 kW · 1 MWh
≈ €2.3M CAPEX entry format for lower-traffic junctions and phase-one deployment.
Deployment
New build and retrofit
Designed in at masterplan stage for new connections, or retrofitted at existing signalised junctions during scheduled upgrade works where the corridor allows.
Junction Physics

The Measured Reference Case.

Rathbeggan, Co. Meath, Ireland is Umpireal's measured reference junction: 9,323 vehicles per day. The stop-start cycle at this single junction wastes approximately 400,000 litres of fuel and €708,000 per year, emitting approximately 1,016 tonnes of CO₂. Busier junctions scale accordingly: a signalised junction in a 50 km/h zone models at roughly 1,950 tonnes of CO₂ per year, rising to roughly 3,835 tonnes in a 100 km/h zone. A busy junction wastes 1 to 3 million litres of fuel annually. The Umpireal node prevents 8 to 12 GWh of vehicle energy waste per year by removing the stop entirely, and the full node models net carbon negative, up to −2,101 tonnes of CO₂ per year at full scale.

Comparison · Signal Optimisation
Google Green Light: ~24 t CO₂ per junction per year
Google's Green Light programme optimises traffic-signal timing with AI. Per Google's 2026 Environmental Report, it saves approximately 13,000 tonnes of CO₂ across roughly 540 intersections: about 24 tonnes per junction per year. Optimising the signal shortens the stop. It cannot remove it.
Comparison · Geometry
Umpireal: ~3,000 t CO₂ addressed per busy junction per year
The BEAR Crossing removes the stop itself. At a busy junction that addresses on the order of 3,000 tonnes of CO₂ per year: roughly 125 times the per-junction impact of signal optimisation. The problem is not the car. It is the junction. Umpireal solves it by geometry.
Glossary

Canonical Definitions.

Term
Momentum Tax
The recurring cost every economy pays at signalised junctions. Vehicle kinetic energy, already paid for in fuel or battery charge, is destroyed as brake heat at the stop line, then paid for a second time on re-acceleration at the engine's least efficient operating point. At the Rathbeggan reference junction this tax is roughly €708,000 per year at one crossing. It applies to every vehicle type, combustion and electric alike, because the loss is geometric, not mechanical.
Term
Innerspace
The 4th compute environment. Land was discovered. Sea was explored. Space was launched. Innerspace was engineered. Innerspace is the protected structural volume created within the fabric of a road junction when the BEAR Crossing is built: permanent, serviceable, below-grade rooms hosting AI compute, BESS, utilities and civic or commercial uses, with no land acquisition and no surface footprint beyond the junction that already exists.
Term
BEAR Crossing
Umpireal's patent-pending junction geometry (application IE 2025/0540, PCT in progress). Pedestrians and cyclists pass through a bright, daylit route below the carriageway while vehicles maintain momentum above. The conflict point between people and traffic is removed structurally, not managed by signals. The crossing creates the structure; the structure creates the Innerspace.
Term
Negalitre
A litre of fuel that is physically never burned because the junction no longer forces the stop. The litre remains in the depot. Litres are the invariant canonical unit; euro figures are derived illustrations that move with fuel prices. Estimated range: 1 to 3 million negalitres per busy junction per year, extrapolated from the measured Rathbeggan case of approximately 400,000 litres at 9,323 vehicles per day.
Term
Dyperscale
Coined by Umpireal: the end-of-life liability of disposable compute infrastructure. Orbital data centre constellations with no servicing or decommissioning plan, subsea pods that cannot be economically retrieved, and hyperscale shells abandoned through special-purpose-vehicle insolvency. The Umpireal alternative is a 100-year civil asset in which only the hardware inside is ever replaced.
Term
Umpireal · IaaS · HaaS
Umpireal is Urban Momentum Preservation plus Innerspace Real Estate. IaaS (Infrastructure-as-a-Service) is the landlord model: the node leases powered, cooled compute rooms to operators. HaaS (Hardware-as-a-Service) is the operator model: Umpireal leases GPU racks, operates the compute and rents capacity at market rates. The base case is IaaS; HaaS is modelled upside.
