Ray Kurzweil: Exponential solar http://apocadocs.com/s.pl?1248534367
Our favorite part of this TED talk (which is worth watching in its entirety), is the exponential photovoltaic efficiency increase (starting around 5:43), "eight doublings away from providing 100 percent of our energy needs." Currently PV is doubling in efficiency:price every two years; now that nanotechnology is being applied, doubling could increase dramatically, he implies. Would it not be fabulous if this is true? We could then have the energy to de-carbonize and de-methanize our atmosphere and possibly de-acidify the ocean with floating solar-powered smartboats. Eight to sixteen years? If, as Kurzweil posits, the other developments in computing, nanotechnology, information interpretation, and general progress grows exponentially..., then in eight years, a radically different world awaits. And how will we make it?
