"We'll probably continue to need jet fuels for a long while but their's certainly no reason that we can't have trains, busses, cars, trucks which run on renewable energy sources from solar farms, wind driven generators, wave generators, and hydro electric dams."

I ran the numbers last year for what would be required to power a hydrogen based economy based on publicly available information. If you just wanted to replace foreign oil imports, you'd have to build over 250 large nuclear reactors. Windmills? The number of 1 megawatt windmills necessary to do that would be obscene. For reference, we've had trouble putting up only 50,000 cellphone towers over the last 20 years and a huge windmill is no less an eye sore. You'd need many, many more windmills if you could find suitable sites for them.

"I wouldn't think that having a business degree from Yale or Harvard would in itself make you any more or less likely to be a terrorist."

Tsk, tsk, McGrath. I think statistically speaking we can be fairly sure that Yankee MBAs who ran Enron would be more likely to buy their way out of an situtation than get involved in terrorism. Maybe resort to a little blackmail or price fixing, but, hey, those are whitecollar crimes, not torrorism. :D
