Anyone have a good idea when these will be available for consumers?

Lithium prices have faced a massive crash, so there is no cost penalty for them anymore. Sodium's cost benefit isn't that significant now, and while other technical benefits exist, the question remains, is it worth it to setup an entire new factory from scratch for that marginal benefit?

So really just assembly and sales then. I suppose it's a good start and maybe if business takes off they can figure out their own cells.

But looking at the discharge profile of Sodium-Ion [1], then a 24v stable output would need about 48v at 100% battery charge and that means cost and complexity on the input and output sides to keep a steady voltage over the discharge cycle. LFP have a much flatter discharge curve but it's a much greater concern with Sodium Ion. Sodium Ion is also criticized for its lifetime cycle degradation.

LTO (Lithium Titanate) batteries hit the sweet spot between both chemistries and are used in electric buses, but I still like Sodium batteries for their environmental considerations.

Wouldn't it be great to somehow harvest power from the temperature swings between night and day in arid regions? Also large changes between sea level and cruising altitude.

I know black tourmaline and certain lithium compounds being pyroelectric generate power upon temperature change due to mechanical stress, which instigates piezoelectricity.

"If the goal is maximum electrical energy generated per degree shift, single-crystal PMN-PT (Lead Magnesium Niobate–Lead Titanate) is currently the top-performing synthetic material." [2]

Doesn't matter for cars, but I think that's pretty good/important for grid storage.

This company got sold for scrap.
