Sodium is an interesting battery chemistry. First, we are never going to run out of salt, second it is highly recyclable, and third it cheap. Cheap as salt!

I love the A00 designation, it is basically the Wuling MINI EV class of vehicle: top speed 60 MPH, range 100 miles, efficiency 8 miles/kWh...blah, blah, blah! It is roughly the same class of vehicle as a 1960 VW Beetle.

The point I wish to make is that 200 kg of sodium batteries gives a good range, for a light weight vehicle that should stick to city driving, and perhaps the secondary road systems for visits to the 'country'.

A secondary point is to consider hybrid battery packs: sodium ion for range and lithium ion for oomph!, highway driving benefits from 'passing power' after all.

My driving needs could be met with a $5K Wuling MINI EV, something like the GM Bolt EV is overkill for my situation but I predict it will be a best seller as long as Treasury doesn't kill the tax credit.

I'm not sure about the actual numbers but something like the Wuling MINI and the GM Bolt twins should satisfy about 70-80% of the market. Can you imagine the demand for used Bolts when the $4K used tax cred kicks in?

The transition is getting very interesting very fast.
