Looking Overseas, currently 1/7 of all cars in Argentina and 1/4 of all cars in Italy run on natural gas. According to T. Boone Pickens, there are a total of 8 million vehicles in the world that run on Natural Gas but only 142,000 of these are in the U.S. (Can you say 'GROWTH market appeal' ?)
Anecdotally thinking..Maybe the Pickens Plan has a chance AfterALL ? (Or at the very least give US something resembling an ENERGY PLAN focused on switching OUR country's transit fuel of choice to something Cheaper, Cleaner, Domestic and More Abundant like Natty Gas.)
