From Engadget: Korean carbon-coated lithium-ion battery could cut recharge times down to minutes

Korean, carboncoated lithiumion battery could cut recharge times down to minutes

Anyone who’s had to recharge an EV — or, for that matter, any mobile device with a very big battery — knows the pain of waiting for hours while a lithium-ion pack tops up. South Korea’s Ulsan National Institute of Science and Technology has developed a conduction technique that could cut that charging time down to less than a minute. By dousing the nanoparticle materials of the battery in a graphite solution that’s then carbonized, the researchers make a web of conductors that all start charging at once; current batteries have to charge towards the center slowly, like a not-very-edible Tootsie Pop. The immediate goal is to develop a secondary battery for an EV that could provide extra mileage in a matter of seconds. Here’s hoping that the Ulsan team’s fast-charging battery is more viable than others and spreads to just about everything — we’d love to have EVs and laptops alike that power up in as much time as it takes to fill a traditional car at the pump.

From Droid Life: Ubi Kickstarter Begins, Always On Voice Activated Internet Device for Your Home

Say, “Hello” to Ubi. Ubi is short for ubiquitous computer because Ubi is always on and always listening. It is a truly hands-free device for your home that plugs right into an outlet on the wall, then connects straight to your home’s WiFi network. So, what can you do with Ubi? Ubi can do voice-based searches on the Internet, act as a personal assistant, control a home’s climate, be a baby monitor, and also act as a notifier for when receiving emails and other notifications.

The team is hoping to have Ubi ready and shipped out by January of 2013, but needs your help to make it happen. Check it out on Kickstarter and let us know if Ubi is something that  interests you. It definitely has our attention as long as it doesn’t go all HAL on us and telling humans what we can and cannot do.

Cheers Leor and Dominick!

From Autoblog: Study: U.S. has fewer cars per person than Europe, but still uses twice as much energy

Filed under: ,

l'Arc de Triomphe

Here’s a shocking statistic: The United States has fewer cars per capita than Italy, Germany, France, Spain, Belgium, Japan, Australia, New Zealand and 16 other countries. Even more dramatic is one of the potential causes: A declining American middle class.

According to an Atlantic report on a new study conduct by the Carnegie Endowment for International Peace, we’re ranked just 25th in the world in per-person car ownership. The actual number stands at 439 cars per 1,000 Americans. Further, the U.S. is an outlier when you compare the number of vehicles per capita to household consumption. While we have one of the highest rates of household spending, car buying is in decline here. It is this disparity that points to the widening income gap in the U.S. as a potential cause of our low rate of car ownership. Indeed, car ownership rates track with the size of a nation’s middle class, according to the report.

To add insult to injury, despite our low rates of car ownership, Americans still consume roughly twice as much energy as most Europeans.
