Suuure. And lithium is infinite.
- pfdietz 8y ago150 ppb in seawater.
- hopler 8y agoIs it efficient to harvest?
- pfdietz 8y agoNot currently competitive, but the thermodynamic minimum energy goes as the log of dilution.
- 420codebro 8y agoTranslate that for me please.
- pfdietz 8y agoAs an aside: googling gave various numbers for Li in manganese nodules, but maybe around 100 ppm. There's about a trillion tons (!) of nodules on the ocean floors, so that would be 100 million tons of Li (and billions of tons of cobalt, used in Li-ion electrodes.) This is probably not worth mining just for the Li, but if nodules are mined for other metals (like cobalt) it might also be economical to extract the lithium.
- pbhjpbhj 8y agoWe just need cheap batteries first so we can harvest the nodules with robots ...
- imtringued 8y agoIt is about as infinite as steel.
