It sounds like a leap forward in this revolutionary technology had been delayed.
"Going long" on Tesla may eventually pay off.
Unfortunately, there is too much hot air in this over-financialized, under-techovised system bubble to stand the pressure of market volatility and hubris.
The great Tesla battery-breakthrough will probably initiate the next great business-industrial expansion, if there ever is one . . . likely to happen ten or twenty years from now if investors are lucky.
As for "mining metals more efficiently" . . . good luck with that in this tail-end phase of the largest resource depletion frenzy in the history of the world.
