  • 200-pound device -- blown by wind -- can explode mines
    Necessity posed by living near a minefield in Afghanistan eventually proved the mother of invention for Massoud Hassani, who has developed a 200-pound mine-exploding device that, despite its heft, can be blown by the wind to trigger mines in its path. Hassani is now working to refine his "mine exploder" with GPS and steerability. (3/5) LinkedInFacebookTwitterEmail this Story
  • 3D microprinter greatly accelerates the process
    Time is of the essence for Nanoscribe, whose new tabletop 3D microprinter can reduce to a minute what used to require an hour's worth of printing time for microstructures. The key to the added speed is a tiny mirror that moves to reflect the device's laser beam at various angles. MIT Technology Review online (3/5) LinkedInFacebookTwitterEmail this Story

  • Mechanization the answer to construction-labor shortage in India
    To counter a labor shortage in rapidly growing India's construction industry, the sector is looking to step up its mechanization and prefabrication to match levels in the more developed world. The move also comes in response to demand for higher-quality and more environmentally sound structures as well as the necessity of taller buildings for the nation's expanding urban centers.

  • Manufacturing with little machining opens way to multi-fuel engine
    New internal combustion engines that can operate on any type of fuel and do so with increased efficiency is the goal of a joint project by the U.S. Defense Department and Kashmerick Engine Systems. The K6-Cycle System employs six cycles and a separate, insulated chamber to boost fuel combustion efficiency. Key to development of the engine, however, has been technology that allows for the manufacture of complex parts with little or no machining. (3/4) LinkedInFacebookTwitterEmail this Story
  • Team closer to claiming prize for human-powered hovering
    More than 30 years after the American Helicopter Society announced the Igor I. Sikorsky Human Powered Helicopter Competition, a team from the University of Maryland came close to claiming the prize. Last year, it achieved a 49.9-second hovering flight with the Gamera II, which was a modification of an earlier design. The rotorcraft is 30% light than an earlier version and specifically designed to exceed 60 seconds in the air. However, the team, while doing well this year, didn't meet the requirement of a 60-second flight at a height of 10 feet -- all within a 10-meter by 10-meter space.

  • Young inventor builds prosthesis from bicycle parts
    A high school student in Alabama invented a low-cost prosthetic leg built entirely of spare bicycle parts. Parker Owen was inspired by a friend who had been on a mission trip to Latin America, and he realized that charitable donations could only purchase a limited number of commercial prostheses. He plans to visit Honduras this summer and make 20 to 30 more prostheses for those who need them. WKRG-TV (Mobile, Ala.) (2/28) LinkedInFacebookTwitterEmail this Story
  • Another app for engineers helps sort through a confusing market
    The proliferation of mobile apps designed for engineers is certainly welcome but the profusion can be overwhelming, writes Mark Crawford. And that's why the addition of yet another app, "Apps for Engineers" from CFE Media, is particularly helpful. "Engineers can quickly search the best mobile apps in the market, discover the ones that address their needs the best and download them immediately," said CFE Media chief Steve Rourke.

  • Mechanical engineer with USACE puts her mind to it
    Margaret Jones is a mechanical engineer with the U.S. Army Corps of Engineers deployed in Afghanistan. She's been the project manager overseeing some work in Iraq, Kuwait, Saudi Arabia and the United Arab Emirates and has received the Bronze de Fleury Medal awarded to individuals who have "rendered significant service or support to an element of the U.S. Army Engineer Regiment." Jones notes that there were not many women role models while she was in college, "but I remembered what my dad told me, ‘You can do anything you put your mind to'."
