It was a hell of a bet to make, but I doubt that Musk would make a claim like that if he wasn’t sure he could back it up!
I’m determined to get myself a Powerwall at some point to offset or completely remove my requirement for an electrical grid connection here. In theory, a single Powerwall unit with the right Photo-voltaic panels would give me enough power to run off-grid completely.
Recently, I’ve been hearing things being said that he’s all show and just marketting shite, but he’s backed up pretty much everything he’s ever set out to do. I honestly admire the guy. If the upcoming sports car can actually do what they claim, I think a lot of people will change their minds on electric vehicles and the associated technology.
Tesla Motors, Solar roof, Space-X, BFR… bring it on.
If Tesla could actually be the ones that crack the mass-production of Graphene, then they could steer the course for a lot of technology for the next 20 years.
