SUBSTRATE: OFF-GRID, UNDERGROUND AI DATA CENTRES
For sovereign / mission-critical workloads.
THE CONSTRAINTAI's bottleneck is DATA CENTRE DESIGN
The industry’s current proposal is to concentrate the global economy and military command stack into AI data centres — while building grid-dependent, monolithic capacity above ground, in natural disaster zones, with little protection against drone attack.
10 YR DELAYS
Grid connection timelines are approaching a decade
79%
Of the existing data centres are in high-risk weather zones
40%
Of planned US data centres are in significant-to-very-high tornado zones

Drone incursions around military and critical infra across the US, UK + EU
AND THERE ARE NEW THREAT VECTORS
■ 01 | NEW THREAT VECTOR March 2026, 3 AWS data centres were attacked by Iranian drones.
Iran labelled major cloud and tech assets "enemy technology infrastructure", claiming the facilities support U.S. military and intelligence operations in the Gulf.
MILITARY TARGETS
■ 02 | NEW THREAT VECTOR2021, US authorities arrested a man who allegedly plotted to bomb an Amazon data centre, which he believed would "kill off about 70% of the internet".
Law enforcement agencies across the US, UK, EU, Japan, South Korea and South America have explicitly warned developers that high public anger over the massive energy and water demands of AI data centres poses a risk of physical incursions and public protest movements, prompting calls for robust facility security.
SABOTAGE
SEARCH FOR ALTERNATIVE DATA CENTRES EXPENSIVE, AWKWARD, RISKY
The industry is exploring alternative data centre designs to address these challenges. Each approach offers potential advantages, but also introduces significant trade-offs.
Non-exhaustive list below.
ORBITAL DC✓ Free unlimited solar energy
✓ Reduced permitting friction
✓ Modular + Scalable
X Extreme maintenance challenges
X Deployment requires large, reusable rockets
X New threat vectors: Anti-Satellite Weapons, Collisions, Radiation
OFF-SHORE DC✓ Independent low-cost wave / nuclear energy
✓ Reduced permitting friction
✓ Free, unlimited cooling
✓ Modular + Scalable
X Expensive off-shore platform maintenance
X Deployment requires boats + marine operations
X New threat vectors: Piracy, Cable Exposure, Sea Water, Storms
UNDERWATER DC✓ Free, unlimited cooling
✓ Reduced permitting friction
✓ Modular
X Extreme maintenance challenge
X Deployment and scaling requires boats + marine operations
X New threat vectors: Cable Exposure, Sea Water, Underwater Drones
■ THERE IS A BETTER WAY
UNDERGROUND✓ 30-50% less energy demand
✓No grid interconnection delays or costs, uses existing headroom within local grids.
✓ Reduced permitting friction , very low visual impact and surface footprint
✓ Modular + Scalable
✓ Cooling enabled by sale of waste heat to local off-taker / landlord
✓ Conventional maintenance
✓ Resistant to extreme weather, surveillance + physical attack
✓ Combines the colocation capabilities of edge with the power of hyperscale.
X Geology + groundwater constrain some sites
X Higher upfront excavation + civil cost
X Challenging large-scale equipment replacement
