> I wonder if it would fit the use of excess renewable electricity. It's exactly the opposite. The pots[1] in the smelter get their lifetime reduced if they have to be restarted, and if restarted multiple times that can be quite significant[2]. They can survive without power for a few hours, but they freeze over after a day or so which leads to the most damage. As such they really want stable and cheap electricity, like hydro.
