Propane/CNG/LPG are, go ask T. Boone Pickens even though he has a horse in that race.
The solution is a "Chevy Volt" that runs exclusively on Gaseous Fuels that are filled at home via this device:
Just think of it, a Series Hybrid that is off the "Refinery" backlog. Lots of Nuke-Plants would help as well.
Now, if we can only get the fartknockers in the Sierra Club, the House, and Senate to let us drill for the 100+ years supply we have here in the U.S....
Is there some reason that a car/truck designed to be "flex-fuel" won't run on "propane/CNG/LPG" as well as a "standard gasoline engine"?
Hot damn, we have a new name for the so-called “Anti Greenhouse Gas” GW folks.
FART KNOCKERS!
