I'd love to have them here in San Francisco, but have to wonder if they'd work better where things are a bit flatter. Unlike the other radical city-transforming transportation idea, the Segway, these appear to be cliff-safe.

The logic seems a bit odd, though, because it says that the reason it won't reduce certain types of pollutants is that there "was already a cap on sulfur emissions and one on nitrogen oxides was likely to follow. Is is possible such caps are a bad idea, then, if they cause people to not bother reducing their output of pollutants, since all it would end up doing is allowing someone else to pollute more?"

"Hubble is one of the great observatories," (NASA chief) Griffin has said. "It has revealed fundamental things about the universe of which we had no idea."
