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.
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.
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.
Research by Nosang Myung , a professor at the University of California, Riverside, Bourns College of Engineering , has enabled a Riverside company to develop an “electronic nose” prototype that can detect small quantities of harmful airborne substances. Nano Engineered Applications, Inc. , an Innovation Economy Corporation company, has completed the prototype which is based on intellectual property exclusively licensed from the University of California.
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.
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'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.
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.
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.
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.
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.
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.
Lansdale Semiconductor, Inc. president, R. Dale Lillard, announced recently the availability of the MC13150 a narrowband FM Coiless Detector intermediate frequency (IF) subsystem targeted at cellular and other analog applications. This wireless integrated circuit (IC) was originally designed and built by Freescale Semiconductor, Inc.
