Yes, PBS had a special (perhaps 10 years ago) about what would happen if there were no more people on earth. It was interesting to see what "went down" forst. i do recall the NYC subways lasted longer than i expected.
The world is going nuts. But, I appreciate your reply. One other question. How much does one of these gizmos cost? What kind of fuel does it use? (Years and years ago, in my occasional trips from Oak Ridge to Knoxville, I would take a back road, because I could buy the cheapest gas at Rocket Fuel. It was $00.23/gallon. (Well, thus was a long time ago.)
