I hope that anyone who attends the rallies will attempt to get there via transportation whose propulsive system does not emit carbon dioxide.

(That pretty much eliminates everything except fuel cell cars that run solely on hydrogen and nuclear-powered submarines.) Human-powered transportation doesn't qualify, of course. But the exercise should put things in perspective regarding the relationship between energy and emissions.

Building fuel cells requires LOTS of energy, i.e. CO2 is produced!

I find it odd that a brigade of hybrids will drive around the whitehouse. Why not sit, walk, ride a bicycle? Hybrids still emit CO2. Furthermore, I drive an SUV, but most places I walk to. I love to point out to these kooks who preach about their cars (anything besides an SUV or truck), yet they drive much much more than I do. When I offer to sit down and figure out how much fuel each of us consumes over a year, they usually just grovel then continue on with their stupid rhetoric the next day.

Takes carbon energy to produce hydrogen as there's not enough naturally occuring to do the trick.
