The fuel for DT fusion is heavy water and lithium. Everyone leaves out the lithium part for some reason. They are considerably more rare than hydrogen. But more common than uranium for sure.
- stocknoob 5y agoLithium is more common than lead (https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth...). If fusion required heavy water and lead, would you care that it was left out as an ingredient?
- u320 5y agoI'm a proponent of fission so obviously I don't see the lithium thing as a huge problem. It's just that I don't like the "it runs on just water" takes. Honesty works better in the long run.
