Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.

ChemTec is an engineering-driven company, and engineering is really about applying the Laws of Physics. We’re familiar with analyzing gas flow rates, accounting for expansion coefficients, and monitoring the position of suspended magnetic pistons, but optical engineering is outside of our realm. Or it was until a customer set us a challenge we couldn’t resist.

For most of us, the air we breathe is cleaner now than it was a decade ago. That’s good news, but it does depend on where you live. The American Lung Association’s (ALA) 2015 “State of the Air” report says, “Nearly 138.5 million people—almost 44 percent of the nation—live where pollution levels are too often dangerous to breathe.” The situation is especially bad in the western USA, with many urban areas in California suffering high levels of air pollution.
