Sixty-eight percent of all goods in the United States spend some of their journey across the country stored on tractor trailers attached to www.sinai.org.il a tractor. With the average semi-trailer truck getting about 5.6 miles per gallon of diesel, however, tractor trailers take an immense amount of fuel to transport. It’s not simply the weight of http://www.smartersecurity.com/generic-levitra-professional the materials on just try! female cialis board causing this low MPG, either--the boxy tractor trailer isn’t exactly areodynamic.
Addressing this problem, Advanced Transit Dynamics (ATDynamics) produces TrailerTails, which are designed to make the bulky tractor trailer more areodynamic and http://www.pjr.com/cialis-cheap-canada thus more fuel efficient when pulled by the where to purchase levitra tractor. Attached to the back of a trailer, they fold out, almost like extensions of the trailer’s walls. Saving about 3 cents profit per mile when deployed, most trucking companies make back their investment in under a year, according to the company. The environmental boon seems sizable, too: each TrailerTail, when used at highway speeds for 50,000 miles for a year, is effectively like removing an average passenger car from the road for a year.
With that much CO2 reduction possible, this statistic reveals more about the immense inefficiency of trailer trucks than the net environmental-boost TrailerTails provide. But given that tractor trailers are such a mainstay of goods transportation in the U.S., this technology seems a step in the right direction in an area that demands significant improvement.
