not feeling CME? then perhaps CGS is more your speed. the colorado green shuttle is a recycled veggie oil powered shuttle that can take you from DIA to vail in 2 1/2 hours.
like many articles about biofuels, the gas 2.0 profile of CGS refers to the use of vegetable based fuel as “green”. while the production of recycled vegetable oil is clearly greener than petroleum based fuels, whether or not biofuel emissions are an improvement (particularly with NOx emissions) is in dispute.
biofuels, particularly recycled vegetable oils, are incredible methods of voting with your wallet- signals to our economy that green technology is an important facet of our lives and is worth developing. but the sustainable qualities of biofuels are at best questionable, and might be better thought of as transition technologies than green solutions to a global problem.
