## The Thermodynamics of AI
Cloud computing is heavily abstracted. When a user queries an LLM or trains a model, they do not see the massive physics occurring in an Ohio cornfield. Training advanced neural networks generates catastrophic amounts of physical heat.
### FAQ
**Q: What is PUE and why is it destroying electrical grids?**
A: Power Usage Effectiveness (PUE) measures inefficiency. A standard data center PUE is 1.45x. This means that if 50 Megawatts of power is pumped into the Nvidia chips, it generates so much localized thermal radiation that the building must pull an additional 22.5 Megawatts off the public electrical grid *strictly* to power massive water-evaporation chillers and industrial fans. This massive drain on municipal power and water is the hidden, physical supply-chain ceiling capping AI scale.
