  • “‘When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest. Do not go over your vineyard a second time or pick up the grapes that have fallen. Leave them for the poor and the foreigner. I am the Lord your God.” - Leviticus 19:9, 10



  • I wouldn’t write off EV usage too quickly. The lithium batteries in EVs right now are around 160Wh/kg. The sodium batteries coming out of production lines now are about the same, but are also substantially cheaper, safer, and built out of more abundant materials.

    Yes, if you compare them to top of the line lithium batteries coming out of assembly lines now, they don’t look as good, but those batteries aren’t in actual cars yet. It’s very likely that we’ll see cheap EVs running sodium batteries, and they’ll often be good enough. We need more charge stations more than we need better batteries (as far as EVs go).
