Sodium ion batteries are just about ready for mass production, they take up twice the amount of space as lithium but are just as effective and far cheaper

What is your source on that? I heard some news about china making some breakthroughs on sodium ion batteries but I am waiting for independent confirmation on that because, well china has let us down more often than not with “bleeding edge” tech.

I was thinking molten salt would be a better energy sink for the here and now.
