Energy storage possible huge advance

If this can be applied to Tesla batteries, for example, it would be a major advance.

Storage is all.

Same number of batteries with double the distance possibly

OR

Half the batteries , less weight, more distance?

Interesting.

I would imagine it would not cost much to change the battery production.
