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.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
