Valveless Hydraulics Cuts Fuel Consumption in Construction Vehicles
Purdue University professor Monika Ivantysynova and doctoral student Naseem Daher discuss research related to new hydraulic steering technology, while graduate student Michael Sprengel looks over the electronic controls of a front loader. Researchers led by Ivantysynova, a fluid systems professor at Purdue's School of Mechanical Engineering, have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment.

An interesting idea. There would be less plumbing; fewer hoses to dry out, seals to fail and losses from the hoses flexing during actuation. I wonder if there is a weight benefit from the reduced plumbing too.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
