"A proposed massive data center project in Utah will span over 80 square kilometers and generate a thermal load of ~16 GW, equivalent to the daily heat of 23 atomic bombs according to physics professor Rob Davies."
The statement accurately reflects calculations made by Utah State University physics professor Rob Davies regarding the proposed Stratos AI data center project in Box Elder County, Utah. However, the project encompasses roughly 40,000 acres (about 160 square kilometers or 62 square miles)—which is larger than 80 square kilometers—and has been approved at the county level amidst ongoing controversy and adjustments rather than a finalized statewide mandate.
Why this score
↑ Professor Rob Davies calculated a thermal load of ~16 GW, matching the 23 atomic bombs per day comparison.
⚠ The project footprint of 40,000 acres spans roughly 162 square kilometers, which exceeds the 80 square kilometers stated.
↓ Box Elder County commissioners approved the project, though aspects and scaling face continuous public and political debate.
🌐 FULL SPECTRUM CONTESTED
ConsensusLocal authorities in Box Elder County, Utah, have approved planning for the proposed Stratos hyperscale data center and associated natural gas power project (backed by Kevin O’Leary/MIDA), originally spanning ~40,000 acres; Utah State physicist Rob Davies’ preliminary analysis calculates a full-build ~16 GW thermal load (9 GW IT load + 7-8 GW generation waste heat) equivalent to the energy of roug
↔ The project is only in early/proposed stages, has been scaled back, faces legal and environmental hurdles, and may never reach the cited full size or thermal output.Who: Project skeptics, The Register, local Utah reporting, some X analysts and Grok summaries of status
Strongest argument: Approvals so far are zoning/planning-level via MIDA/Box Elder; full construction permits, financing, and build-out of 9 GW are years away or uncertain, with reports of downsizing from 40k acres and pauses, so the 16 GW figure remains a hypothetical maximum rather than an approved reality.
Assessment: Supported by multiple sources describing it as 'proposed' and questioning if it will be built; X posts note scaling and legal issues; fails to erase that local approval of the project area did occur and Davies’ numbers match the original public plans.
↔ The '23 atomic bombs' comparison is a sensational thermodynamic equivalence that overstates real-world continuous environmental impact versus an explosive event.Who: Industry supporters, some engineers/commentators, developer-side responses in coverage
Strongest argument: Waste heat from a 55%-efficient gas plant and IT load is steady low-grade thermal energy dissipatable over a large desert valley footprint with cooling tech and atmospheric mixing, not a concentrated blast; actual temperature rise estimates (a few °F day/night) are model-dependent and mitigable, unlike bomb effects.
Assessment: Math of energy equivalence holds per Davies (widely un-refuted in sources); however, the analogy is rhetorically charged and ignores dispersion, efficiency gains, or phasing—impacts on Great Salt Lake watershed ecology remain projected and unresolved pending detailed studies.
↔ Economic and strategic benefits of the AI/power infrastructure outweigh localized heat concerns.Who: Developers (O’Leary), MIDA, pro-growth Utah voices, AI industry advocates
Strongest argument: On-site generation avoids grid strain, creates jobs/tax base in a rural area, and supports national AI competitiveness; heat can potentially be reused or managed, and desert siting minimizes some conflicts compared to denser regions.
Assessment: Jobs/power claims appear in supportive framing but lack quantified counter-evidence in retrieved sources; fails against Davies’ and ecological warnings on heat island effects near the Great Salt Lake, which sources treat as serious and under-studied.
Open questions• What is the current approved acreage and power capacity after reported scaling and reviews?
• Will detailed environmental impact assessments confirm or revise Davies’ preliminary thermal and temperature-rise projections?
• What cooling, heat-recovery, or mitigation technologies will actually be deployed if built?
