China launches high-speed test train capable of 310 mph, shaped like an ancient sword

According to an old “Simpsons” quote, there’s nary a thing that can outrun a greased Scotsman. That’s no longer the case, as Chinese train manufacturer CSR Corp Ltd. unveiled a 500 km/h (310 mph) high-speed test train over the weekend. The train, which consists of six cars, is shaped to look like an ancient sword, reinforced with carbon fiber, and has a maximum tractive power of 22,800 kilowatts. Similar (if not identical in terms of proposed speeds) projects currently under construction include the 310 mph maglev train planned by Southwest Jiaotong University, the Tokyo to Osaka bullet train planned for 2045 and the proposed 269 mph maglev train from Anaheim to Las Vegas. The test unit is part of China’s trillion dollar effort effort to build 13,000 km (8,078 miles) of high-speed rail network by 2012, and about 20,000 km (12,427 miles) by 2020. This new launch comes after a series of high-speed train-related troubles throughout 2011 in which the former Railways Ministry chief, Liu Zhijun, was accused of pocketing $122 million and subsequently terminated from his position; this was followed by a July collision between two high-speed trains in Wenzhou, which killed at least 40 people and injured another 210. Still, the new test train tops out at 310 miles per hour and is shaped like an ancient sword, so past snafus can probably be forgiven.

Nissan Leaf Nismo RC swaps basic comforts for a carbon fiber body and some racing good looks

Electric vehicles may have that instant torque thing going for them, but they’re still a bit behind when it comes to giving heart palpitations to those diehard petrolheads. Hoping to change that perception, Nissan is setting up to unveil a brand new concept vehicle, dubbed the Leaf Nismo RC (that stands for Racing Competition, not “radio-controlled”), which strips the one-size-fits-all Leaf down to its constituent elements. The drivetrain is still 100 percent electric, however it’s now powering the rear wheels instead of the front, while things like the rear seats, trunk, audio system, carpeting, and navigation have been completely removed. A carbon fiber chassis helps the Nismo RC keep weight down to 2,068 pounds (938kg), equivalent to just 60 percent of the original Leaf’s heft. Yes, the Leaf is now lighter! In performance terms, you’re looking at a car that can hit 62mph within 6.85 seconds, max out the speedometer at 93mph, and last a terrifying 20 minutes under racing conditions. This prototype vehicle will debut at the upcoming New York Auto Show and will thereafter help Nissan research better aerodynamics and, presumably, slightly better energy efficiency.

Bluetrek releases lightweight Carbon: world's first carbon fiber Bluetooth headset

When this rather smashing little piece of gadgetry made its way through the FCC last week, we didn’t have a whole lot of details to share about the “world’s first carbon fiber Bluetooth headset.” Well, Bluetrek’s making the Carbon official today with a $70 price tag and a full set of specs. The thing weighs in at a mere .25 ounces, touts Bluetooth v3.0 support, and allows for four and a half hours of talk time or five days on standby. It also comes with a set of four earbuds in different sizes, so anyone can rock the lightweight headset no matter how big, or small, the ear hole. The Carbon is now on sale at the source link below. Full PR after the break.

Apple hires carbon fiber expert to posit composites

If you’re going to compete in the consumer electronics business then you’d better have a solid grasp of industrial design and materials science. Otherwise, you’re just another manufacturer trying to eke profit from drab slabs of commodity plastic. With the exception of the MacBook, Apple’s entire Mac lineup is currently cut from aluminum. However, Apple’s been caught experimenting with its newly acquired Liquidmetal materials recently, even as rumors swirl around new ultra-lightweight and durable carbon fiber components and enclosures. Speculation about the latter has been fueled by an Apple patent application for a process that would use carbon fiber materials woven into the reinforced device housings of mobile telephones, laptops, desktops, and tablets. Interestingly enough, the patent app was filed by Kevin M. Kenney (developer of the first all carbon fiber bicycle frame) on behalf of Apple back in 2009, a man who changed his job title to “Senior Composites Engineer at Apple Inc.” on LinkedIn at some point after March 1st (according to Google cache). Of course, a carbon fiber laptop is far from unique — just reference the Sony G11 from 2007 or 2008′s Voodoo Envy 133 if you want to see how it’s done. But if Apple makes a wholesale shift to carbon fiber in the months ahead then you can expect the horde of me-too OEMs to follow suit a year later. See the before and after LinkedIn profiles for Kenney after the break.

Volkswagen's XL1 concept plug-in diesel hybrid has 313MPG fuel efficiency, questionable aesthetics

Steaming down the autobahn could be about to get a whole lot more efficient. Volkswagen has carted out its newly updated Super Efficient Vehicle concept, now dubbed the XL1, which — after a great deal of fuzzy math, we’re sure — is rated at a 313MPG fuel efficiency and produces only 24g of CO2 per kilometer traveled.
