They are a nice IDEA but in the end they AIN'T going to save us. With them we still got to do the same DESTRUCTIVE behaviors. We still got to mine the shit out of the Earth, ill still be pumping who knows what into the air building them and yes then the batteries, they won't last forever and from my understanding they are toxic as shit. Nevermind  HOW the materials are acquired( Afghan invasion, and others) Countries will be invaded and expolited, like they already are ,JUST to make the rich even richer. What you don't know, they WON'T tell you is besides the BIG businesses, that ARE the biggest contributors of pollution but the "mighty" military machine is the ...SECOND BIGGEST contributor to pollution. Sorry the EV car isn't going to save us all it's going to do, as always, make the rich...richer.
