The U.S. Navy should place a high priority on development of new all-electric ships and associated drive, power conditioning, and distribution systems. So recommends the Committee on Technology for Future Naval Forces, a unit of the National Research Council. The committee attempted to identify technologies that will be of greatest importance to naval operations out to the year 2035. The panel's re-port contends that gas turbine propulsion units, modular rare-earth permanent magnetic motors, and power control module technologies have matured to the point that all-electric ships appear feasible. The direct electric drive for ships and submarines, the group adds, offers "unique advantages" in reduced volume, modular flexible propulsion, lower acoustic signatures, enhanced survivability, and new capabilities. Incorporation of superconductivity into motors, energy storage, and power distribution, the study states, will further increase capabilities of all-electric craft. The committee also advises the Navy to step up research into microelectromechanical systems.
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.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
One expects to see outlandish apparel at major global fashion events, but New York Fashion Week may have outdone itself, and set a new bar for Paris and Milan, when it put an Ebola jumpsuit in the spotlight.
