Well, china will get the hold of that technology first for what i know, together whyte India ... And no, those photovoltaics, bioeermics, miniature mechanics and chemical potential energy technologies will make sure in future, that the grid will be used minimally. (just applied intelligently everywhere it needs to be in the "self feed integration" manners) ... if i would be able to rightly sketch the picture of our sciences potential - what we are able to do in that way already and in near future ... you guys would be surely astound. We just have to get some time to rethink that tech in usage and labs we have.
