I mean if so called wonder materials like Graphene can actually be harnessed to make new generation ultra cheap solar cells may be something might happen. What we need actually is a Global Manhattan project which focuses on something like the 100 most promising approaches and builds and tests prototypes. This should be funded both by Govts. and the rich individuals. I think sharing of intellectual property can do a lot of good in solving the Carbon free energy conundrum and then getting it cheap enough for everything else. My guess is that a project like this can deliver solution(s) 10-20 years before free market will.
