An H100 operation costs about 100 million Landauer limits
Physics sets a floor for erasing one bit. At peak, an H100 spends about 100 million times that energy per operation: a scale, not a like-for-like test.

Tesla patented the AC induction motor and the Tesla coil. He did not invent AC or the light bulb, and radio is murkier. His patents, dated.

Software & AI
AI training makes GPUs swing power together, and data centres can drop off the grid. What causes both, what each fix costs, and what to ask your utility.
