Protean Electric in-wheel motors have the stuff to make an F-150 turn green
An energy efficient Ford F-150 certainly sounds like an oxymoron, but the folks at Protean Electric have proven that even this gas guzzler can go green. So how'd they do it? Well, with in-wheel motors of course. This isn't the first time we've seen this technology put to use, but if things go according to plan, Protean's version of the in-wheel motor could be road ready as soon as next year. The things weigh 68 pounds (31 kilograms) a piece and offer 110 horsepower per wheel. When pared with this F-150 -- rocking a custom battery -- they offered up 100 mile-per-hour speeds and a range of 100 miles. That might not be enough to take you across the great state of Texas, but it's certainly sufficient for tooting around the ranch.

E-Traction's in-wheel motor sportin' hybrid electric bus
We've seen in-wheel motors in the past, but implementing the technology is not without its share of challenges. On one hand, it's difficult to coordinate motors that have no mechanical connection to each other, while on the other hand electric motors are designed to spin much faster than the wheels, in order to generate the desired power -- adding complexity while decreasing efficiency. A company in the Netherlands called e-Traction may have those problems licked, and now they've developed a diesel-electric hybrid bus that they say offers fifty percent better fuel economy over existing diesel buses. The vehicle also employs a GPS-based system that switches off the diesel engine entirely while operating in areas with dense traffic, reducing emissions. The company has been awarded contracts to retrofit seven commercial buses with the technology, and hopes to branch out soon into garbage trucks -- because nothing says 'green' like hauling junk off to a landfill.
