Here was an interesting video about an Ethopian solar power maker (region restricted, I saw it once, now YouTube has it blocked from me), a single guy with some ideas. One of the things I think that is going to happen is that solar power is to the developing world like cellphones were.
Without massive infrastructure gains, but a desire to be connected and have the technology, cellphones spread rapidly throughout the developing world. To the point where there was often better proliferation than in developed world areas.
Without the infrastructure of power companies that developing world has, I think solar proliferation is going to be a fascinating and rapid explosion in the developing world, so videos like the above are things I’m actually trying to keep an ear out for. Glimpses of that potential leapfrog.
