“That’s not a photo of safely stored anything. I mention that so people don’t lose track of facts.”
It’s a photo of a ‘formerly safely stored liquid’ that you referenced.
And (to keep you on track):
Liquid fuel gives >350 mile range, with re-charge in less than 5 minutes.
THAT is the primary goal for any other vehicular energy storage method. Until the "alternative" energy vehicle can meet or exceed that standard, it will NOT be competitive with liquid fuel.
