    Watershed Moment

    This frothy flume is what 300,000 gallons of water per second looks like. A 60-hour surge of almost 75 billion gallons, it’s part of an effort to revitalize the ecosystem of the Colorado River and the Grand Canyon. Teams from the U.S. Geological Survey, the Grand Canyon Trust and 25 other agencies have been working together since 1995 to develop a plan that will mimic natural flooding to redistribute sediment that would normally wash downriver.

    Chin Jabber Wakes Drivers

    By PopSci Staff Posted on 4.1.2009 3 Comments

    You shouldn't fall asleep at the wheel with this chin jabber on the job. Worn around the neck, it holds a sharp prong under the driver's chin. If his head nods, the point quickly awakens him. Invented by K. H. Liman, of Rye, N.Y., it has a rubber knob below the tip to prevent serious injury.

    Here it is: the high-speed train your kids will take when they backpack around Europe. Its called the AGV (Automotrice a Grand Vitesse, which translates to High-Speed Self-Propelled Unit). This 224 mph machine is the successor to the TGV, which started the European high-speed train boom in the early 1980s.

    I think the train looks really weird...unlike the TGV Duplex, the double-decker TGV. EO

    The Tallest Mobile Crane

    By Posted on 3.26.2009 10 Comments

    Built for tasks like lifting 55-ton generators to the top of 300-foot windmills, the Liebherr 11200-9.1 might just be the world’s most monstrous truck. The 108-ton 18-wheeler doubles in weight when the boom—-which with extensions can reach 47 stories—-is attached. Fully assembled, it can lift up to 2.6 million pounds. Without the boom, it can drive on public roads, so getting it to a job site requires five fewer trucks than it would take to haul in and assemble an equally large fixed crane. It’s also far easier to move from place to place once it’s on-site.

    EO- Haha...I don't know how true that could be...but there are very advanced materials out there that might be able to.

    Building a Bigger Bird

    By Posted on 1.22.2008 6 Comments

    Courtesy airliners.net Having passed its emergency-evacuation test last weekend, the Airbus A380 is officially certified to haul a staggering 853 passengers—that's how many people safely escaped a darkened test aircraft in less than 80 seconds. The A380's capacity puts it well past its next-largest rival, Boeing's venerable 747, which has held the title of world's largest active commercial jet for almost 36 years. When the A380 takes to the skies on its first commercial flight with Singapore Airlines later this year, it will probably max out at around 500 people (800-plus is for a nightmarish single-class setup). So how does an aircraft this big get itself built, let alone get in the air?  Check out this cool time-lapse video of an A380 assembly to find out, and stick around for the end—the double-time painting process is amazing to watch. —John Mahoney
