> A great early use case for fusion will directly use the heat for these industrial processes. There is no chance that early fusion plants will be small enough to justify building them in the same building as a factory. They will start large. > For example, aluminum requires ~14-17MWh to produce 1 ton The Hall–Héroult process runs at 950 C, just below the melting point of copper. It is close to twice the temperature of steam entering the turbines. It is not something that can be piped around casually- as a gas it will always be at very high pressure because lowering the pressure cools it down. Molten salt or similar is required to transport that much heat as a liquid. Every pipe glows orange. Any industrial process will effectively be a part of the power plant because of how difficult it is to transport that heat away. Also NB that the Hall–Héroult process is for creating aluminum from ore, and recycling aluminum is the primary way we make aluminum.
