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.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
