Can't imagine paying $700 USD to live in a tiny 4 foot tall "pod"...

I'd sooner buy a used van like an old ford econoline and live in it. Probably would be cheaper.

Well damn, we might actually see alternatives to Lithium batteries some time soon...
I 100% figured it was just going to be vaporware. Especially when considering all these fancy battery tech we had been seeing in the news for the past, what, 15 years? And none of them ever made it to market.
https://newatlas.com/energy/natron-sodium-ion-battery-production-startt/
Charges/discharge 10x faster than lithium and doesn't burst into flames... But holds less charge. Will be interesting to see where this ends up in a few years after they tweak the capacity per kg a bit.
(might be tech news worthy if someone wants to make a thread)

... read the article maybe?
Will get to it, just got up a bit ago.
Edit: still not super impressed. The longevity is certainly better than even Li-Fe, but charge/discharge rates appear to only be about on par. (Keep in mind Lithium Iron Phosphate already boasts dramatically better charge/discharge rates than Li Ion and LiPo)
As the article mentions, stationary applications are probably going to play to the strengths of this tech, probably displacing home battery backups, but is unlikely to displace lithium tech in EVs.
If the tech is cheap though, then I’ll be a lot more interested, particularly in areas that frequently get power shutoffs during fire season. Though until we see products hit the market, it remains to be seen.
Lithium Iron Phosphate cells in production (ie, stuff that’s actually in use) also hits somewhere between 90-160 Wh/Kg, while this Sodium tech appears to currently hit 70-160 Wh/Kg, again, not currently commercially available. I’d definitely be pleased if commercial projects can hit the higher ranges though.
