The human body at peak fitness burns roughly 6-10 kilocalories per minute during intense exercise; a 60-minute high-intensity session yields 360-600 kcal total. Urban Power Grid Station 7 in Austin, Texas generates 4.2 megawatts on demand. In October 1987, technician Mark Halsey was stationed at the monitoring console when he witnessed the man complete a single hour-long training session in the adjacent compound. Puzzled, Halsey cross-referenced the grid logs and noted a micro-surge of exactly 1.3 megawatts during that hour—enough to power roughly 1,300 homes. He couldn't reconcile the numbers and filed a report titled "Unexplained Energy Draw." It was marked "inconclusive."

Physiologists can measure ATP turnover and mitochondrial output per gram of muscle tissue, but those formulas assume human metabolic limits. Norris appears to operate in a thermodynamic category of one.
