I'm not trying to suggest that propane in vehicle sized fuel containers is too dangerous to use. I'm trying to suggest that methane is even safer than the propane we are already used to handling.
The pressure required for CNG has reason for safety precautions and strict design requirements. But it is no different than systems we commonly used for acetylene welding, a far more dangerous gas.
It’s my experience with acetylene, LP, and gasoline since a young boy that formed my opinions.
Thanks for the posts, I appreciate hearing from someone close to the subject at hand.
