* Massachusetts - Study: Stiffer pavements could reduce vehicle fuel consumption by 3%

Cambridge,MASS,USA -Truck News (CAN) -May 24, 2012: -- A recently released MIT study shows that using stiffer pavements on US roads could reduce vehicle fuel consumption by as much as 3%. Officials say the resulting savings could add up to 273 million barrels of crude oil per year ($15.6 billion worth based on today’s oil prices) and an annual decrease in CO2 emissions of 46.5 million metric tonnes... The study is the first to use mathematical modelling rather than roadway experiments to look at the effect of pavement deflection on vehicle fuel consumption across the entire US road network, officials said in a release... The study found that deflection under the tires is similar to that of beach sand underfoot: With each step, the foot tamps down the sand from heel to toe, requiring the pedestrian to expend more energy than when walking on a hard surface. Stiffer pavements would decrease deflection and reduce that a car’s “footprint” ...
* China - Hong Kong to increase EV charging stations to 1,000 by June
Hong Kong,China -Ecns, by Xu Rui -25 May 2012: -- The Hong Kong SAR government is continuing to promote electric vehicles (EVs) in the region with better facilities and more advanced technology, said Financial Secretary, Tsang Chun-wah, at the launch ceremony of a charging station project held Thursday at the Star Ferry Pier in Central. The installation of 500 EV charging machines will be finished by the end of June, at which time about 1,000 charging spots will be scattered across the 18 districts of the region. All neighboring stations will be no further than 20 km from each other. The number of local EVs has rapidly grown from only 16 at the end of 2009 to more than 310 in late April...
