Audi proved the worth of its diesel engine technology with a win at the 2006 Le Mans, breaking new ground for the legendary endurance race. This year, Audi ups the ante with two cars using hybrid diesel-electric drive systems.

The drive technology, branded by Audi as e-tron, uses a V-6 turbo-diesel engine on the rear axle, and an electric motor on the front axle. Similar to Kinetic Energy Recovery Systems (KERS) being deployed in F1 racing, the Audi R18 e-tron quattro captures braking energy in a flywheel. The car can then convert the energy of the spinning flywheel into electricity, … Read more

Automakers have endorsed a connector to charge electric vehicles in as little as 15 to 20 minutes, a technology which promises to make public charging stations more compelling.

German and U.S. automakers Audi, BMW, Chrysler, Ford, General Motors, Porsche, and Volkswagen yesterday issued a statement saying they will support the same charging interface.

Called the Combined Charging System, the standard can charge electric vehicle batteries with alternating current from a home outlet, direct current from a home outlet, or "ultra-fast" direct current from public stations. The system will be demonstrated next week at the International Electric Vehicle … Read more

Greenpeace has uncovered documents that the group claims indicate Apple has plans to draw more power at its North Carolina data center than it has stated.

The environmental watchdog group yesterday published a permit application and permit for back up diesel-powered generators at Apple's Maiden, N.C., data center that's now under construction.

The documents indicate that Apple requested and was approved to use significantly more than the 20 megawatts of power Apple projects its data center to use at full capacity. The company received environmental permits to install 54 megawatts of diesel back up power, but because … Read more

It's time for your DVR to get as smart as your iPad. If designers get it right, energy use from household electronics will stay under control without sacrifices in features.

By necessity, mobile devices, such as tablets and smart phones, need to be clever about power, just like an efficient hybrid car uses many tricks, such as turning the engine off when idle, to sip less gas.

By contrast, always-on electronics devices, such as set-top boxes, DVRs or often game consoles, operate as if they were going top speed at all times. As more devices in the home, such … Read more

What would you do for free Wi-Fi? Mexican Internet provider Terra has teamed up with ad agency DDB to offer free Wi-Fi in public parks to dog owners who clean up after their pets.

As seen in the absurd promo vid below, owners who deposit poop in the special bins in 10 parks in Mexico City will be rewarded with free Wi-Fi, broadcast through routers shaped like doggy bones.

The more you add, the more minutes you and everyone else gets. The bins seem to have a simple scale to weigh the poop, so they would likely still work if people put rocks or trash in them instead. … Read more

Toyota will officially unveil the RAV4 EV next week, an all-electric SUV that could be an important indicator of electric vehicles sales overall.

The company earlier this week sent out a notice that it will debut the RAV4 EV on Monday May 7 at the International Electric Vehicle Symposium (EVS26) in Los Angeles, an important conference for EVs.

Toyota has shown off concept RAV4 EVs already, but important details such as price and availability have not yet been disclosed.

The all-electric SUV is the fruit of a partnership between Toyota and Tesla Motors, which is supplying the electric powertrain for … Read more

To make its data center greener, Apple will be getting energy from old garbage.

The company plans to power the fuel cells at its Maiden, N.C., data center with biogas from landfills, according to a regulatory filing spotted by Data Center Knowledge.

The filing also indicates that Bloom Energy will supply the 4.8 megawatts worth of fuel cells that will partly power the data center. Yesterday, Bloom Energy CEO K.R. Sridhar told CNET that the company will supply its 200-kilowatt parking space-size Bloom Boxes to Apple.

By using biogas rather than natural gas to power its fuel … Read more

Ever since hybrids became popular, with the second generation of the Toyota Prius, the question arose of whether the fuel savings justified a hybrid car's higher price. The extra expense for a hybrid car has been called the hybrid premium.

The extra cost for a hybrid car comes from the additional equipment in the driveline. Along with the gas engine, hybrid cars have an electric propulsion motor, a high-voltage battery pack, and a power control module, this latter component determining how to feed electric power into the drive system.

Now, with many automakers offering some type of hybrid car, … Read more

On the day Bloom Energy officially opened shop on the East Coast, the company's CEO confirmed Bloom will supply fuel cells to Apple's North Carolina data center.

Bloom Energy today is breaking ground on a factory in Newark, Del., to build its Bloom Energy Servers, or Bloom Boxes, which produce electricity from natural gas or biogas.

The facility, which was a former Chrysler plant, will have the capacity to turn out 1,000 Bloom Boxes a year, Bloom Energy CEO K.R. Sridhar said in an interview with CNET. Each fuel cell, which is the size of few … Read more
