Siemens and Cohda Wireless plan to work together in the area of vehicle-to-infrastructure devices, which share information between vehicles and roadside infrastructure. Siemens says it will deploy transport infrastructure including sign gantries and traffic lights. The District of Columbia’s water utility, DC Water, unveiled a $470 million waste-to-energy project that will produce 10 megawatts of electricity from the wastewater treatment process. The energy will power around one-third of a water treatment plant. An investment of nearly $600 million by Rolls-Royce will be used to upgrade and modernize its Indianapolis, Ind., operations. The investment aims to replace outdated infrastructure and some equipment that dates from World War II. A report from the statistical arm of the National Science Foundation says that from 2003 to 2013, the number of immigrant scientists and engineers grew from 3.4 million to 5.2 million.
