Remember Intel’s Edison from CES, the SD card-sized computer that would run Linux and also sounded too good to be true? Well it was! Intel has admitted that the device will now use an Atom processor and be larger as a result. Shame.

Over a century ago, Thomas Edison developed a rechargeable nickel-iron battery, designed to power cars. Remarkably, the technology is still used by some people to store energy from solar panels and wind turbines—but now, Stanford engineers have tweaked it to charge 1000 times faster. More »
Back in the 1920s, Thomas Edison’s dream of an electric automobile was ultimately foiled by those meddling petroleum engines. But thanks to nanotube research from Stanford University, one legacy from that era may regain some glory: nickel-iron batteries. It turns out that carbon nanotubes doped with nickel and iron crystals can top up the normally slow-charging cells in a matter of minutes — according to the scientists, that’s almost 1,000 times faster than in the past. Although the batteries couldn’t power your Volt or Prius due to a lack of energy density, they could give an extra jolt to their lithium-ion siblings for quicker starts and regenerative braking. The researchers are working on improving stability to allow more charging cycles, but it might be an extra in-your-face for Edison if it pans out.
Ubiquitous nanotubes could reboot Edison-era nickel-iron battery technology originally appeared on Engadget on Thu, 28 Jun 2012 02:51:00 EDT. Please see our terms for use of feeds.
