CNG for cars, especially all car in present driving mode. The infrastructure is lousy at present but can be made very viable in the next year or little better if natural gas is present, especially in larger or medium size metropolitan areas. We can get present gas stations to get the CNG units ifthose companies want to produce them in mass. That take care of getting the CNG. All Cars can be converted, trucks must be converted. it all depends on us. Present Gasoline should be taxed royally to get enought people to covert. The carbon footprint will be much, much better. WE CAN DO IT, WE MUST DO IT.
