If you are driving off a cliff, someone telling you to slow down isn't much of a help. (Well, slowing down while you turn in a new direction is likely to be a good idea.) By burning fossil fuels, humanity is now driving itself off a climate cliff toward extinction. We need to completely stop burning "stuff" (fossil fuels, or anything else) for energy. Yet to thrive we really do need lots of energy -- in fact, even more than we now are using. This book shows how we can meet both of these needs by creating a new infrastructure context in which existing technologies will work far better than they do now. Not only will we get all our energy at less than one tenth the cost per kilowatt-hour, we will speed up long-distance transportation at least tenfold, plus give everyone a chance to enjoy space travel. And that is just the beginning.
