reverendbedford··on Westinghouse sees a tech disrupter in its eVinci microreactorThat works for some processes (making aluminum and more recently steel) but I'm not aware of any electrically heated processes for making concrete. Cheap, clean electricity could unlock a lot of things though.
reverendbedford··on Westinghouse sees a tech disrupter in its eVinci microreactorSodium reactor outlet temperatures are around 550 C. There are other reactor concepts that come close to 1000 C, but it's a huge technical challenge.
