Apple's iPad costs precious little for you to charge it each year, according to a new study.

The Electric Power Research Institute (EPRI) conducted a study recently to see how much the iPad costs in electricity if users fully charge it every other day.

Convincing a nation so steeped in its car culture to think differently about the way we drive is a test of both patience and persistence. But the 2012 Vehicle Concept Showcase at Stanford University's Center for Automotive Research yesterday offered some interesting arguments about how our future personal transportation will better suit our needs.

One feature that may take some adjustment for many drivers is wheel configuration. Only two of the eight vehicle concepts rolled out at the showcase had the tried and true four-wheel configuration -- most were three-wheelers. As the makers of Switch Vehicles pointed out, dropping … Read more

Do children still enthuse about cars? Toyota is hoping they'll become future buyers with the Camatte, an EV concept showing this week in Tokyo.

Named for the Japanese verb kamau (to care), the Camatte is designed to prompt tykes to care about car ownership. The seats and pedals can be adjusted so that kids can drive while an adult in the back seat helps with steering.

It won't be road-worthy, however, and is designed for use on go-kart tracks and other private facilities, with a top speed of 25 mph. Can that really rev kids up? … Read more

What began as a 24-hour test a year ago will become business as usual on Wednesday as a range of big-name Internet companies permanently switch on the next-generation IPv6 networking technology.

And now there's no turning back.

"IPv6 is being enabled and kept on by more than 1,500 Web sites and ISPs in 22 countries," said Arbor Networks, a company that monitors global Internet traffic closely.

Internet Protocol version 6 has one big improvement over the prevailing IPv4 standard it's designed to supplant: room to grow. However, moving to IPv6 isn't simple, which is … Read more
