Bingo! There has to be plans for when things catastrophically fail. They seem to have taken good measure, but it's bound to happen eventually.
I'm with you there...that seems to be a part of the plans for Dubai with so many of their new projects being electric, but I still would need to research how they're actually generating that power right now or planned for the future.
I wouldn't be surprised if they will be the first ones to have a working hydrogen fusion reactor (0% carbon footprint woot!) The would really drop the mic with regard to innovations in power generation.
