Audi's R18 e-tron Quattro receives a dual-hybrid makeover for 2014

First introduced into rally racing in 1980, Audi’s AWD Quattro system has become synonymous with all wheel drive performance.

For 2014, the Le Mans champion is back to defend its title packing more than just new laser headlights – it has a completely redesigned dual-hybrid system in hand. Read More

The Voltmaker takes the latter approach, providing your smartphone with enough juice to make a quick phone call with a flick (or more accurately, several flicks) of the wrist. Read More

This is the set up used in “series” or “inline’ hybrids like the Chevy Volt, which differs from parallel hybrids like the Toyota Prius, where the wheels can be driven by the electric motor or the internal combustion engine (ICE). Researchers at the German Aerospace Center (DLR) have developed a new type of range extender that can be powered by a range of different fuels. Read More

Pavegen harvests energy from Paris Marathon runners

While the term "electrifying" can sometimes be used to describe breathtaking performance in sports, it's not often you'll find it used for marathon runners. Yet, that's precisely the word I'd use to describe this year's Paris Marathon, which took place on Sunday April 7. You see, as the feet of almost 40,000 runners hit a 25-meter (82-foot) installation of special tiles at the beginning of the 26-mile (42-km) course, kinetic energy was harvested and turned into usable electricity.
