Momentum Tax™
The permanent thermodynamic penalty imposed on every vehicle passing through a signalised road junction. Vehicle kinetic energy, already paid for in fuel or battery charge, is lost as brake heat at the stop line, then paid for a second time on re-acceleration at the engine's least efficient operating point. It applies to every vehicle type, combustion and electric alike, because the loss is geometric, not mechanical. Global scale: an estimated 5,000 TWh of energy wasted and 1.3 gigatonnes of CO₂ released per year, at a total economic cost of approximately USD 5 trillion annually in lost productivity, wasted fuel, delayed logistics, avoidable emissions, accident risk and the wider human toll of commuter stress. At the Rathbeggan reference junction, the tax is roughly €708,000 per year at one crossing.

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, semi-excavated 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.

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.

Continuous Flow Digital Junction™
The product category invented, patented and named by Umpireal. A civil junction in which vehicles maintain momentum on a continuous-flow carriageway above, pedestrians and cyclists pass through a grade-separated route below, and the resulting Innerspace hosts AI compute and battery storage. Above ground: transport, without the stop. Below ground: energy and digital, without new land. One civil object, three infrastructure functions. The BEAR Crossing is the geometry; the Continuous Flow Digital Junction is the category the geometry creates.
Term · Geometry
Daylight Basement™
The room typology inside the Continuous Flow Digital Junction. Because the shell is semi-excavated 1.5 metres below original ground level and the carriageway is semi-elevated 2.5 metres above, clerestory openings on the raised sides admit natural daylight and passive ventilation into the compute and battery rooms below. Standard shell height is 3 metres, in a 400mm precast concrete structure. This distinguishes the Umpireal structure from tunnels, buried bunkers or subterranean data halls, producing a human-serviceable working environment with normal building standards. The result is a basement with windows.
Term · Physics
Gravity Battery™
The passive potential-energy exchange at the elevated crest of the Continuous Flow Digital Junction. Vehicles gain potential energy on the 2.5 metre climb onto the raised carriageway, and release the same energy on the descent. The exchange calms traffic without wasting kinetic energy as brake heat, in contrast to conventional speed bumps and raised tables which convert kinetic energy to heat and force re-acceleration. Traffic calming is delivered passively, at zero energy cost, with no moving parts. Access ramps are correspondingly shallow, benefiting cyclists, wheelchair users and buggies, because the underpass descends only half the depth of a conventional grade separation.
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.

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.
