Apple News:Apple is currently testing three different prototypes of the next iPhone

A Taiwanese Mac news site with a history of accurately predicting future Apple products says Apple is currently testing three different prototypes of the next iPhone. From what can be gleaned from the Google translation, tw.apple.pro says one of the iPhone 5 prototypes features a a slide-out physical keyboard -- a form factor that Steve Jobs and Apple have never seemed too keen to embrace.

Another iPhone 5 prototype is said to closely resemble the current iPhone 4 with a longer-lasting battery and an 8 megapixel rear camera. The site suggests that if this prototype is released, the iPhone 5 will be to the iPhone 4 what the iPhone 3GS was to the iPhone 3G -- in other words, a spec upgrade, but with no external redesign.
There is no word on what the third prototype features. As AppleInsider points out, tw.apple.pro has a relatively solid history of producing rumors that turned out to be true, including the white iPhone 4, the iPhone 4's battery, the 2008 MacBook redesign, the new Multi-Touch iPod nano, and the 2008 MacBook Pro's unibody redesign. However, in 2009 the site claimed a 15-inch MacBook Air was in development, but that never materialized. This of course doesn't mean a 15-inch MacBook Air has never been in development -- or even prototyped. Given the positive track record of rumors from tw.apple.pro, it's reasonable to believe that just because a reported prototype doesn't make it to market doesn't mean tw.apple.pro's information was false.
So, is tw.apple.pro's report correct? It's possible, but if they are correct, which of the three prototypes will become the iPhone 5? Only Steve Jobs and a handful of people at Apple know for sure. The next iPhone most likely won't ship until June, so until then, there's plenty of time for more rumors and speculation.

New battery technology from Argonne helps laptop-last longer

battery technology from http://www.bestlaptopbattery.co.uk
This month, thousands of new Chevy Volt owners will begin the real road tests of the first mass-produced plug-in hybrid electric car. While much of the car's engineering is unique, consumers may be unaware that some of its most extraordinary technology is inside the nearly 400-lb. battery that powers the vehicle in electric mode.
The battery's chemistry is based in part on a revolutionary  breakthrough  pioneered by scientists at the U.S. Department of  Energy's Argonne  National Laboratory. The new development helps  the Volt's battery-a  lithium-ion design similar to those in your cell phone or laptop-last  longer, run more safely and perform better than batteries currently on the  market.
"To me this cuts right to the heart of green energy," said Jeff Chamberlain,  who heads Argonne's battery research and development. "This battery  technology is a step towards energy independence for the U.S.; it helps create jobs; and it can have a positive impact on the environment."

The story begins in the late 1990s, when the DOE's Office of Basic Energy Sciences funded an intensive study oflithium-ion batteries.
"Existing materials weren't good enough for a high-range vehicle," explained Michael Thackeray, an Argonne Distinguished Fellow who is one of the holders of the original patent. "The Argonne materials take a big step forward in extending the range for an electric vehicle."
In order to improve the design, scientists had to know how batteries worked at the atomic level.
