@ ALL FIGHTING OVER CNG:
Compressed natural gas, or CNG, is a natural gas under pressure which remains clear, odorless, nonpoisonous, and non-corrosive. Natural gas can kill, however if it is present in large concentrations and thus reduces the amount of oxygen available in the air, such that amount of oxygen remaining in insufficient to sustain life. Although vehicles can use natural gas as either a liquid or a gas, most vehicles use the gaseous form compressed to pressures above 200bar
