I am not sure that there is a new idea, or that this guy is saying anything I didn't hear one of my engineering professors say 5 years ago. However, the problem with these calculations is that they cannot take into account new technology that will be created in the next 30 years. To fufill our energy needs, we only need to tap into 5% of the Sun's energy that reaches earth. So while discussions using current technology are important, lets make clear that the long-term goal is sustainable, low pollution (and radiation) energy, and that it can be achieved.
