Hasta La Gadget!

Electric cars hold the potential to eliminate your monthly gasoline bill, but if you want to go more than 100 miles or so at this point you’d better plan to make a bunch of lengthy pit-stops along the way. There are various solutions, like the Volt‘s on-board generator or Nissan’s offer to replace your Leaf with something a little more traditional for long weekend trips into the country. But, to us, battery swapping seems like the best plan. Better Place is the leader in this space but BAIC, the Beijing Automotive Industry Holding Company, is showing off its own solution, the charmingly named C71 EV that looks like what might happen if a SAAB and a Toyota spent a crazy night together in Shanghai. It’s a $45,000 car with a 60Ah floor-mounted battery pack that can be swapped in just five minutes, each delivering 150km (93 miles) of range and can naturally be charged by more traditional means (a plug) should you not be in such a hurry. The car is said to be available sometime next year, but we’ve heard that one before.

BIAC’s C71 EV has hot-swappable battery packs and a questionable sense of style originally appeared on Engadget on Wed, 10 Nov 2010 03:36:00 EDT. Please see our terms for use of feeds.

Shifts at a Foxconn factory are typically eight to ten hours a day. Since about half of the company’s Shenzhen employees live on campus, an entire city has sprung up around them. They train. They eat. They play. More »

In Shenzhen’s electronics markets, an entire building is dedicated to Apple products. You can buy white iPhones—at least the backs—by the case. But why pick drab old white when you can get something even snazzier? More »

A report this morning from the South China Morning Post claims that Amazon’s 3G-boasting Kindle is selling fast on the so-called “gray” market in China because of its 3G internet connectivity and browser. The device, it seems, offers the Chinese a rare opportunity to side-step the “great Firewall” of the Chinese government, which restricts access to sites such as Facebook and Twitter. Amazon does not officially sell the Kindle in China, which has the world’s largest internet-connected population at 420 million. The Kindle, which seems to have been overlooked by the Chinese authorities thus far, makes use of Amazon’s own network, Whispernet.

Add the ‘made in China’ tag to yet another gadget: the world’s fastest supercomputer. China says it has the most powerful computing system — a machine called Tianhe-1A.

The supercomputer uses 7,168 NVIDIA Tesla M2050 GPUs (graphics processing units) and 14,336 Intel Xeon CPUs and is capable of clocking 2.507 petaflops or 2,507 trillion floating point calculations per second.

The Tianhe-1A will take the top spot from the U.S. Cray XT5 aka ‘Jaguar’ that’s at the Oak Ridge National Laboratory in Tennessee. The Jaguar can clock 1.759 petaflops and is built using 37,376 AMD processors.

The Tianhe-1A is interesting because it combines CPU and GPUs — much like desktop PCs — to create the world’s most powerful machine. In fact, Nvidia, claims if its GPUs weren’t used, then it would have taken 50,000 CPUs and twice as much floor space to create a comparable computer.

The Tianhe-1A was designed by the National University of Defense Technology in China and will be operated as an open access system for large scientific computations.

The use of GPUs in high performance computing is on the rise. Once seen in PCs used largely for multimedia and gaming, GPU-based computing has become more popular among researchers for its ability to offer raw computing power. While CPU are critical to a PC for their ability to interact with the different computing elements such as memory and disk drives, GPUs can perform specialized tasks especially related to graphics and visual computations that working in tandem with CPUs can speed up computing.

The CPU-GPU combination also helps keep up power efficiency. The system consumes 4.04 megawatts, three times less than what it would have if it were built entirely with CPUs, claims Nvidia.

Overall, the Tianhe-1A is a computing monster. It has 262 terabytes of memory and is housed in 140 refrigerator-sized cabinets.
