I believe there are a few companies already doin’ it.
Musk not needed. Or more efficient zinc air batteries.
“Musk not needed.”
Well, maybe not “needed” but I believe that his own, personal energy is what made Tesla. He is the force behind Space-X.
Like an Edison, the technology may be there, but it takes force of will to make it a reality, too.
