Earlier today I wrote about the potential health risks of racing in Beijing given the very high air pollution levels being measured at the moment: http://inrng.com/?p=11294

It got a little messy in Providence this Sunday…but I liked it.

…and it turned out to be another perfect day
In the U.S. alone, there are an estimated 2 million tractor trailers in active service. Trailers serve as the main transportation method for goods in much of the world, and are also big contributors of greenhouse gases and other air pollution. Mercedes-Benz is trying to address some of the pollution problem with a concept for a new aerodynamic semi-trailer called the Aero. The trailer dramatically improves fuel efficiency, with an 18% reduction over conventional box trailers (with a corresponding 5% reduction in fuel consumption in regular traffic).
However, at the moment, the trailer isn’t street legal. Part of the design of the trailer includes a tapered extension to the tail end that runs a foot and a half past the maximum allowable trailer length in Europe.Mercedes-Benz claims that this taper accounts for a third of the improvement in efficiency and feel a change to the law is needed. “The fundamental feature of the revolutionary Aero trailer is to be found in the trailer’s load compartment, whose dimensions remain totally unaffected. The familiar box – measuring 13.6 m in length, 2.55 m in width and with an overall height of four metres – remains available for the freight, just as before.”
