"You mean to tell me!"

This is the exact statement that came out of my passenger's mouth when I explained to her that Compressed Natural Gas (CNG) can fuel the very same engines that gasoline does. The passenger was in near disbelief that she was riding in a van running on the same gas that she cooks with. The next question that she asked was "What are the advantages of using natural gas in a vehicle?" I explained to her that CNG is less harmful to the environment, it costs less, and most importantly, it makes the US more energy independent. Her curiosity had been sparked and she wanted to know how long this technology had been available.

I explained that CNG has been around for decades but do to infrastructure problems, it has not caught on to the general public.
