A Vermont utility, Green Mountain Power, is offering Tesla Powerwalls to customers starting in January.
As anyone who's suffered through an extended blackout can tell you, electric power can be a precious commodity. With the advent of electric cars comes the ability to borrow back some of the energy stored in traction batteries to help deal with emergencies or other situations.
Never underestimate the power of the middle finger. After a rain-delay restart ordered by IndyCar officials at New Hampshire Motor Speedway resulted in a crash, driver Will Power chose to express his displeasure by giving those officials a taste of universal sign language with both hands. The event happened on August 14, and chief race steward Brian Barnhart eventually issued an apology for the decision to get the competition underway again after calling the race off. Still, that hasn't stopped
For electric items that are too mobile to be connected by wire, like – to pull a completely random example out of the air – a car traveling down the highway, the idea of wireless power transmission has a lot of appeal. Several different schemes have been considered, including magnetic induction, microwaves, or even lasers. Now, researchers in Japan are examining a system that would use a radio frequency signal to transmit power.
The concept of being able to charge up a depleted battery without a cord or plug in sight might seem futuristic. But more than a century after Nikola Tesla demonstrated wireless energy transfer, wireless charging systems are already becoming a reality for devices ranging from electric toothbrushes and mobile phones to artificial hearts and LCD televisions. For electric cars, industry analyst Richard Martin and research firm Pike Research predict in a new report that wireless power stations desig
It may not be a particularly glamorous definition of the automobile, but it's true on some level that cars and trucks are individual little power generators on wheels, a fact pointed out here by Wired staff writer Alexis Madrigal. Interestingly, when viewed in that light, the United States has an embarrassment of riches when it comes to overall latent power availability.

To assist their gas engines, Nissan has developed e-4WD, or electric four wheel, which uses electric motors but has no batteries. Is this a hybrid? Yeah. Think of it as a mild series or serial hybrid, which is a kind of hybrid that uses a generator instead of a battery to power the electric motors. Wait a minute, you might say: aren't four wheel drives less efficient than two wheel drive cars? Yes but e-4WD is very light and compact because it's electric.
At one time Japanese regulations prohibited engines in that country producing more than 274hp, and oddly enough a wide array of different engines were all rated at that same level. Given the actual performance of the cars, it was clear that many manufacturers were sandbagging. Audi appears set to do the same with its uber-powerful RS6. The twin-turbo V10 is expected to carry an official rating of 571 hp, but the actual output could be as high as 610hp. Does anyone actually need this much power i
"Thanks God for traction control," was the first thought that ran through our minds when we came across the reported power figures of the new Audi RS6. Floating around the tubes of the Internets are the chassis codes for the new RS6, which look something like this: Audi AG 47 7967 21 AAJ N31 N30 579 426 5002. What does all that mean? Well, the 579 figure is the metric horsepower rating, which is equivalent to about 571 HP, while 426 refers to the kilowatts, and 5002 is a reference to the cubic c
