Wow talk about showing your backside , how about doing some research outside the US media , first there are hundreds of Tesla vehicles already operating successfully in Canada , second solar city was purchased to gain patents not generate revenue , he wanted their tech licenses for his current home "Powerwall" battery setup which he has now released the solar shingle part of so yes you can re-shingle your roof with shingles that are little solar panels the first 2 styles are already on the market with 2 more designs - a Tuscan terra cotta style and Slate coming in 2018 , the cost when amortized over the life of the roof compared to a conventional 30 year asphalt shingle is almost a wash without the value of the energy cost savings of the solar production -put that in your pipe and smoke it . , 30 years being the weather warranty and the power warranty of their shingles ,the impact or damage warranty is Infinite -life of your home .Does it pay to run out and switch your roof over now no but does it pay to switch when your roof is done and needs replacing -hell yes . Third you can add WalMart and JBHunt to the list of pre orders for the trucks , they were actually first in before Pepsi . Walmart is going to test here in Canada so their goes that cold weather myth all Tesla products have always been built with a battery maintenance system that manages battery temperature even when the car is in storage .
People laughed and talked crap about every Paradigm development in human history , there was a time when the swiss were the only people to buy a watch from then Texas Instruments invented a watch powered by an oscillating crystal and what happened ? A national industry with hundreds of years of dominance in the market was wiped out almost over night .It has to start somewhere with someone , it's not going to save the planet it's just a better way and will overcome the old way .
