Self-Charging Power Cell Converts And Stores Energy In A Single Unit

August 22, 2012 6:28 am | Comments

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.

Constructive Conflict In The Superconductor

August 22, 2012 6:20 am | Comments

Whether a material conducts electricity without losses is not least a question of the right temperature. In future it may be possible to make a more reliable prediction for high-temperature superconductors. These materials lose their resistance if they are cooled with liquid nitrogen, which is relatively easy to handle.

A New Route To Dissipationless Electronics

August 22, 2012 5:48 am | Comments

Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a magnetic topological insulator.

Mobile-Phone Users Spending More Dough On Accessories

August 21, 2012 11:02 am | Comments

Mobile-phone owners are not just spending money on their phones and monthly subscriptions. Sales of mobile-phone accessories shot up 32 percent during the first half of 2012 compared with the same period last year, says a new report from NPD Group. Cases proved the most popular accessory, with sales soaring 70 percent over 2011 despite an average 25 percent increase in case prices.

Why No One Has Tamed Email

August 20, 2012 5:42 am | Comments

Everyone complains about email. We’re awash in the stuff. We feel inundated. Overwhelmed. Out of control. Lately there’s been quite a lot of talk about what to do about it. Jordan Cook  hates it , MG Siegler  tried to quit it , and Alan Henry  argues you can’t .  People want Gmail to  speed up , Yahoo! to  catch up , or, someone, anyone, to make something better .

NASA Tests Newest Free-Flying Robotic Lander: Mighty Eagle

August 17, 2012 6:03 am | Comments

NASA's new robotic lander, the Mighty Eagle When NASA's Mars rover Curiosity began its entry, descent and landing sequence two weeks ago, the success of the mission hinged on what was known as the " 7 minutes of terror " -- a period during which NASA was out of touch with the vehicle, relying on its autonomous landing sequence to successfully touch down on the surface.

Restaurant Offers Cell Phone Bribe

August 17, 2012 5:18 am | Comments

A meal isn't a meal without a cell phone. You need to photograph the food and get it onto your Twitter feed, before any of the other diners does the same. It isn't called A Twitter "feed" for nothing, you know. You need to be able to Google "the collected works of Al Green," just in case there's a dispute about who wrote "Let's Stay Together.

Scientists Do The Wet-Dog Shake

Armed with a little more than a hose and high-speed video equipment, researchers have cracked one of science’s wettest problems. As dog-owners know all too well, when their canine companions take a dip in a pond this is swiftly followed by a twisting shake-down that involves an ecstasy of flopping ears and flapping jowls.

Could Minneapolis Get Cleaner Energy With a Utility Takeover?

August 16, 2012 10:18 am | by They decide which bills will be heard and, ultimately, which will be passed into law. Not coincidentally, a champion of clean, local energy was denied a seat on the Public Utilities Commission by the Legislature. | Comments

As we spoke to legislators and activists roaming the halls of the State Capitol this past legislative session, it became increasingly clear that Xcel Energy and other utilities are calling the shots for our energy future. Minnesota spends more than $20 billion a year on energy -- primarily importing polluting fossil fuels -- and the state's utilities typically lobby against decreasing our dependency.

How to Make a Parking Garage Energy Efficient

August 16, 2012 10:12 am | Comments

It's no secret that researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) do cool things — including finding new ways to capture energy from the sun and wind. But there's nothing cooler than working on a parking garage, right? "It doesn't sound glamorous, but it is a place for building energy savings," NREL Energy Efficiency Research Engineer Jennifer Scheib said.

It's Back to the Future on the US Clean Tech Industry

August 16, 2012 10:01 am | Comments

President Barack Obama and Gov. Mitt Romney recently stated how each would "get tough" with China. This reminded me of a conversation with economists I had in Vice President Biden's office several years ago. We discussed how to put together the president's stimulus proposal and the possibility of using clean tech programs — solar, wind, batteries and others — as one of the lynchpins of the program.
