MORE ON ALTERNATIVE-FUEL CARS: Bring it on, I say, though I don’t think we’ll see massive progress soon. The latest AvWeek — I get it all the time, but this issue seems especially attuned to my interests — has a look at alternative fuels for jets, too. Jets really, really need the energy density of hydrocarbon fuels, which means that they should probably be the last to convert to something else (a hydrogen-fueled plane has to be big to hold enough fuel, and still won’t go as far on a tank).

I think that rich celebrities who crusade against global warming, though, should have to use synthetic kerosene made out of biofuels as they jetset around. Or at least extinguish a coal fire or two!
