Smooth-moving robots cut energy consumption

By - August 26, 2015 3 Pictures

With their precise mechanical movements, robots seem like the most efficient of workers, but they can actually waste a good deal of energy. Chalmers University of Technology is developing a new optimization tool that acts like an efficiency expert for industrial robots by smoothing their movements to reduce their energy consumption by as much as 40 percent.

Mercedes A45 AMG gets powerful refresh

By - July 1, 2015 32 Pictures

At what point does a hot hatch become a pint-sized sports car? The Mercedes A45 AMG was already blurring the line, but the engineers over at AMG's Affalterbach headquarters decided that the pint-sized turbo terrier needed more power. Thanks to an extra 15 kW (20 hp) from its 2.0-liter motor, the updated A45 AMG will now hit 100 km/h (62 mph) in just 4.2 seconds.

Wärtsilä's new 31 becomes the most efficient 4-stroke diesel engine in the world

By - June 22, 2015 4 Pictures

Finnish engine manufacturer Wärtsilä must be a fascinating place to visit. The company manufactures some of the most mind-bendingly enormous marine diesel engines in the world, like the record-breaking, 89-foot high, 44-foot long, 110,000 horsepower RTA96-C we wrote about more than 10 years ago. Now, Wärtsilä has another entry in the Guinness Book of Records ... for the world's most efficient 4-stroke diesel engine.

Freightliner SuperTruck shows other transport trucks how efficiency is done

By - April 6, 2015 3 Pictures
Back in 2009, the US Department of Energy issued its SuperTruck Challenge. The program provided funding for truck manufacturers to design and build a prototype vehicle that was at least 50 percent more freight-efficient than a baseline 2009 truck. Daimler Trucks North America recently unveiled its response – the Freightliner SuperTruck. It goes beyond the 50 percent figure, with a claimed efficiency increase of 115 percent. Read More

Device zaps oil to make it flow easier

By - March 2, 2015
It's a simple fact that the more fluid an oil is, the easier it is to pump. That's why oil companies typically heat sections of pipeline, to reduce the viscosity of the crude oil traveling within. Generating that heat still requires a fair amount of energy, however, plus the oil's reduced viscosity produces turbulence it its flow. Temple University's Prof. Rongjia Tao has developed what may be a better alternative – a device that electrifies the oil. Read More

New electrolyte to enable cheaper, less toxic magnesium-sulfur-based batteries

By - November 30, 2014
There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.
