Why electricity, not chips, is the real limit
The surprise of the AI buildout is that the scarcest resource is not chips or money but electricity, and the grid was not built for this. Learn why power became the binding constraint, why connecting a big new load takes years, why data centers are turning to gas and nuclear, and why an unglamorous device, the transformer, quietly gates the whole thing.
Nuclear fission: chain reactions, reactors, fuel cycles
How fission releases energy from heavy nuclei, why neutron moderation determines reactor design, the structural choices behind LWR, CANDU, gas-cooled, fast, and molten-salt reactors, what the fuel cycle actually consists of, and where waste, cost, and safety arguments sit.
