Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That’s why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada’s energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to “all electric” propulsion systems.

An anonymous reader writes “The Netherlands is moving forward with plans to build ‘smart’ highways that can become more easily visible in the dark or communicate weather conditions to drivers. Work will begin as early as next year. ‘Special paint will also be used to paint markers like snowflakes across the road’s surface — when temperatures fall to a certain point, these images will become visible, indicating that the surface will likely be slippery. Roosegaarde says this technology has been around for years, on things like baby food — the studio has just up-scaled it. The first few hundred meters of glow in the dark, weather-indicating road will be installed in the province of Brabant in mid-2013, followed by priority induction lanes for electric vehicles, interactive lights that switch on as cars pass and wind-powered lights within the next five years.'” Read more of this story at Slashdot.
