Video: Power Line Perching UAV Doubles Down on Drone Delivery
Blog 7/8/2014 21 comments Last December Amazon.com unveiled a plan for a delivery system of drones that can deliver packages to people living within 10 miles of a distribution center. One of the reasons for that mileage limit is that the unmanned aerial vehicles the company plans to use only have enough battery life to cover that distance without recharging. MIT is out to change that.
10 Engineering-Friendly Foods
Blog 7/3/2014 38 comments Normally it’s chefs who find inspiration in food. But a number of clever engineers and inventors are doing the same these days, developing new materials, biofuels, ways to harvest energy, and other inventions by using common foods and food waste to create the foundation or impetus for their designs.
3D-Printed Steel Building Structures
Engineering Materials 7/2/2014 22 comments Structural engineers have developed a design method for 3D printing structural steel elements to be used in construction projects. Complex, individually designed pieces can be created far more efficiently, and costs and waste will be reduced.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
