This is the sodium ion battery, already scaling up mass production by CATL. The one they claim should enable a 200-300 mile city car that is fundamentally cheaper than an ICE vehicle. The materials costs are something like half of an LFP battery, and LFP batteries should be cheaper than ICEs too at scale, especially with the new generation of 200-225 wh/kg LFP batteries. The reason why they aren't available is that government, especially the US, are still being unbelievably short sighted about proactive investment in EV switchover. There should be hundreds of billions of dollars being invested to switch over to PHEVs and EVs in all consumer and a great deal of commercial transportation every year. Heck, we should have had PHEVs for all new vehicles mandated 10 years after the Prius was released in 1997, it's just that there was an oilman in the oval office. But Obama wasn't very proactive either.

There should be hundreds of billions of dollars being invested into building out rail, and phasing down cars in every major city. Footpaths and bike lanes cost 1/100th as much as roads for cars, investing in EVs is shortsighted. EVs are better than ICE cars (mostly - I'm not sold on battery trucks and EV utility vehicles), but kerosene lamps are better than whale-oil lamps and yet both should be replaced by light bulbs as broadly and quickly as possible. Sodium batteries are cool as heck, I'd love to see them in UPSes.

  Rail simply takes too long and too much money to lay down. But e-bikes that I agree with you. Our car centric infrastructure basically makes an e-bike. Still pretty dangerous. With minimal infrastructure investment, certainly a thousandth of what would be necessary for a rail line, I said he could make a kick- ass ebike infrastructure completely separated from dangerous cars. Old rail lines are actually really good for this. They're already separated from car infrastructure. But even if you dug tunnels or elevated, a bike path still would be a lot cheaper
