Making the Case for Propane: From Gas Grills to Cars and Trucks
I'm sitting in a coffee shop with Roy Willis, propane advocate, who's driven up from New York City to lobby me on using his fuel in cars and trucks, and darn if he isn't making a compelling case. Why aren't we using propane - the same stuff as in your backyard gas grille - in our cars? It's possible. Today's internal-combustion cars and trucks can run on CNG, LNG or propane with some fairly simple engine modifications.
Right now there are tens of thousands of propane-powered vehicles on the road, but it's regional. There are thousands of propane refuelers, but they're concentrated in California and Texas. Public refueling is a problem for CNG, too - there are 1,000 CNG stations, and half of which are public.
