Based on that article I read in 'Harpers' last week, I suspect the next big bubble will be 'Alternative Energy'. All these biofuel start-ups and windfarms and solar roof outfits is going to need money - and so will the bloodsuckers and con artists who go along for the ride. As motivation, we gots the big global warming scare (arguably legit), peak oil (still in denial but rapidly becoming legit), and the ever increasing price at the pump combined with nasty regimes elsewhere sitting atop the oil we need. Hence, I can see the whole alternative energy thing getting inflated - assuming things don't crash first.
