    .....Solar roadways? Only one way to find out if they are a pipe dream 10

    An outfit called Solar Roadways wants to replace asphalt roads and parking lots with solar cells and claims this idea is practical based on the tests it has run so far. The company has received some SBIR money and has given a TEDx talk on the subject which is viewable on its web site. ...More

    Wind turbines for low wind speeds defy Betz limit efficiency 14

    Many designers of utility scale wind turbines dismiss the idea of using turbines to capture energy from light breezes and in areas where there isn't a lot of wind. Their argument comes from Betz's law which calculates the maximum power available from the wind. The law uses principles of conservation of mass and momentum of the air stream flowing through an idealized cylinder that extracts energy from the wind stream. Importantly, it assumes the use of aerodynamic propeller blades in the turbine....More

    Rant: Spray and gascan nozzles equally idiotic

    Last weekend, in a bizarre burst of energy that had me motivated me enough to spraypaint a rusty old Charmglow grill that had become a certifiable eyesore, I dug up an old can of barbecue black Rustoleum spraypaint from our garage. In a development that added insult to injury, I'd soon discover that the nozzle on this spraycan is a Contraption of Infuriation that rivals the Grand Champion of Horrible Designs, the nefarious late-model Blitz nozzle.

    3D printing's fate according to a Technology Futurist 4

    I recently had an exchange with Jordan Brandt, a Technology Futurist at Autodesk, about 3D printing. "3D printing is for the last mile of factory automation — so in the next couple of years, expect additive mass-production methods to increase factory automation and product customization," predicts Brandt....More

    What's inside GM's recalled ignition switch 3

    We recently took a quick trip to a junk yard to get a steering column from a 2007 Chevy Cobalt. The steering column, of course, also comes with the ignition switch that is the source of GM's recent 1.5 million vehicle recall. We dissassembled the switch so you can see the source of the controversy....More

    The Art of Product Design

    An interesting book crossed my desk recently. Called "The Art of Product Design," by Hardi Meybaum, its title is perhaps a bit misleading. The phrase "art of design," for most engineers, might bring to mind discussions of blended curves and managing the product development process. But that's not at all what you'll find in Meybaum's book....More
