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.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
