Ubiquitous nanotubes could reboot Edison-era nickel-iron battery technology Jun 28th 2012, 06:51 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.

After getting the FCC nod back in the fall of 2010, the white spaces harboring these unused television frequencies were opened up, paving the way for a host of new wireless broadband services. Now, thanks to AIR.U -- a consortium of over 500 higher learning institutions and tech industry partners like Google and Microsoft -- underserved small college towns will soon see deployments of these high speed networks as early as Q1 2013. Not only will the group's efforts help usher in a low-cost wireless solution, but it'll also tackle a major geographic hurdle: building and terrain penetration. Seems these in-development networks run on a much lower frequency than traditional WiFi and, thus, have greater ease broaching thick walls and covering larger expanses. A pilot effort is underway, although exact details as to the where and when have yet to be revealed. Check out the official presser after the break for the full-on rundown.
