The Lawrence Livermore National Laboratory (LLNL) and Navistar are testing drag-reducing devices that could cut big rig fuel use by 12 percent, or 3.4 billion gallons a year. The devices would fit into the areas of the truck that produce the most drag, making it more aerodynamic and try it cheap levitra soft reducing the www.aumm.nl energy needed to buying viagra delivered worldwide propel the truck.
At highway speeds, semi-trucks use more than half of levitra australia no prescription the energy from their engine overcoming drag. With these devices placed at crucial points like the trailer base, underbody and the space between the tractor and trailer, the drag is significantly reduced. The fuel savings amount to a reduction of 36 million tons of CO2 emissions a year -- the same as four 1-GW power plants -- and a cost savings of $10 billion a year for the U.S. trucking industry.
The LLNL's devices, along with other commercially-available ones, are being tested at NASA's Ames Research Center in the world's largest wind tunnel where researchers hope to coax even greater fuel efficiency through the the best place cialis australia large-scale testing. Trucks could be retrofitted with the devices in as little as three years.
