A recent article by Eric Janszen, author of "The Next Bubble: Priming the Markets for Tomorrow's Big Crash,"" (Harper’s, February 2008) makes for interesting reading. The crux of Janszen's argument is that the subprime crisis is just one of a series of "bubbles" and the trick is to be able to predict where the next one will happen. So what’s Janszen's pick? "There are a number of plausible candidates for the next bubble, but only a few meet all the criteria…. There is one industry that fits the bill: alternative energy, the development of more energy-efficient products, along with viable alternatives to oil, including wind, solar, and geothermal power, along with the use of nuclear energy to produce sustainable oil substitutes, such as liquefied hydrogen from water. Indeed, the next bubble is already being branded." To see a clip of Janszen's interview with CNBC's Kevin Kneale, check out this YouTube video.
