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.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
