The above image is a depiction of a tractor trailer made to sit in the world's-largest wind tunnel, at the NASA Ames Research Center, in Mountain View, California. The truck was a part of tests intended to find enhancement in fuel efficiency that could save the trucking industry billions of dollars a year. The device is placed on the rear of the truck and is destined to enhance the truck's aerodynamics.
It is being said that the American trucking industry may perhaps hoard as much as $10 billion, or 3.4 billion gallons of diesel fuel, a year if devices being tested in a joint public-private initiative at the world's-largest wind tunnel here are rolled out nationally.
Over the last few weeks the test results show that new devices can be added onto the nation's thousands of trucks that might enhance fuel efficiency by 12 percent.
The main intention of this was to find a way to assist the trucking and car shipping industry--and by extension, almost every other segment of the economy to cut costs on fuel, and at the same time, reduce carbon-dioxide emissions.
Lawrence Livermore National Lab (LLNL) Director, George Miller explained that the impact on the environment of the 12 percent increase in fuel efficiency would result in an annual decrease of carbon-dioxide emissions by 36 million tons.
