Ok, i'll trust you and read further. :)
Ok, read. I wish i had not. I hope the author is young and will become less pretentious with age. He presents this at the end of the article as THE solution for rural paupers of the third world the grid ignores, lumping Latin America in it. But he still claims it is "the infrastructure model" implying more. Which makes me suspect he believes in an old hippy mantra of decentralized infrastructure that is at least 50 years old. But it matters little.
But, reported by someone else more sober and mature, it is an interesting (and well known) development model for a more limited part of the world that he claims. Don't hope to export this model at this price in Burkina Faso because of the war and corruption there, for example.
I think if we want to read on this interesting topic we should not try to do it via slashdot.
