The post you pointed us to, Lynn (Gladwell's review) quoted former head of the Atomic Energy Commission Lewis Strauss (whom I knew, he was our neighbor in Virginia after he retired from government) on the subject of nuclear power, which Anderson uses in his book and which Gladwell picked apart. Apparently Strauss made a claim that nuclear power would be so cheap that it would be virtually free, ushering in a whole new era of energy use. Gladwell correctly points out that even though the fuel was cheap, the infrastructure necessary to deliver the fuel would require capital expense. (And Gladwell doesn't even bother to note current costs associated with building nuclear plants.) What fascinates me is that we are entering a period when energy is not only not "free" in Anderson's sense of the word, it is going to be increasingly costly. But information... well, I agree with Gladwell that information may want to be free but is going to cost something at some point to some one.
