Battery Storage Could Get a Huge Boost from Seaweed

"Lithium-ion batteries could hold up to 10 times as much energy per cell if silicon anodes were used instead of graphite ones. But manufacturers don't use silicon because such anodes degrade quickly as the battery is charged and discharged. Researchers at the Georgia Institute of Technology and Clemson University think they might have found the ingredient that will make silicon anodes work—a common binding agent and food additive derived from algae and used in many household products.

Iron Man-Like Exoskeleton Nears Production

"By now, with films like Iron Man, its sequel, and Avatar, Hollywood has made us thoroughly familiar with the idea of the robotic exoskeleton. Less well known, however, is that researchers are actually building robotic exoskeletons like the ones envisioned by Hollywood and the comic book visionaries from whom Hollywood pilfers its most lucrative ideas. Among the developers of real-life Iron Man suits (of which there are many, the world over) is a group called Raytheon Sarcos.

An Operating System to Run It All

"Apple and Google will soon have more than just each other to worry about in the race to provide the software for smart phones and tablets. Later this month, Intel will announce that its MeeGo operating system is ready to run devices including touch screen tablets and phones. MeeGo is a Linux-based, open source project created by merging Intel's Moblin and Nokia's Maemo operating system projects early this year." | more

Why CPUs Aren't Getting Any Faster

"In fact, the next-generation of CPUs, including Intel's forthcoming Sandy Bridge processor, have to contend with multiple walls--a memory bottleneck (the bandwidth of the channel between the CPU and a computer's memory); the instruction level parallelism (ILP) wall (the availability of enough discrete parallel instructions for a multi-core chip) and the power wall (the chip's overall temperature and power consumption)..." | more
