NASA engineers in Ohio were moving forward with an oil-free turbine engine, an advanced research program that replaces ball bearings and oil with foil bearings, air, and coatings. But they've been hit by a double whammy that raises questions about the technology's future. First, much of NASA's funding is being diverted to the Columbia investigation. Second, researchers were developing the technology for use as a jet engine, and arrangements with aircraft manufacturers have disappeared given that industry's gruesome finances. Researchers at the Glenn Research Center in Cleveland now face the daunting task of seeking money from a Congress distracted by Iraq or from another industry that needs a large turbine. The oil-free bearing technology has many potential benefits. Air won't burn like oil, so the turbine can run at up to 650C without cooling. There's no chance that air can leak away or get dirty like oil. Additionally, it doesn't require plumbing or pumps. A 50-passenger jet could save 8% in acquisition and fuel costs.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
