rechargeable batteries

Acer appears to have found a solution to notebook users' battery life woes. Its Aspire Timeline 1810TZ apparently delivers a 10x improvement in runtime when compared to other thin'n'light laptops equipped with six-cell lithium-ion batteries. After five hours' usage at a day-long conference the other day, we thought we'd check on how well the Windows 7-based machine would continue to run.  

Beauty, they say, is in the eye of the Wii-holder. The Charge Base IC is a $34.99 induction charging device for Wiimotes and looks like something out of a Frank Lloyd Wright sketchbook. The base sits firmly on the ground while sweeping cantilevered arms reach out to cradle your Wiimotes with magnets.  

Some day in the not-too-distant future, we won't need to plug in our portable gadgets to charge them. We'll simply walk into our homes and sophisticated electronics embedded in our walls will start juicing all our batteries wirelessly. And then our robot butlers will fetch our slippers and make us an extra dry martini.  

Clore Automotive introduces the Christie L1240T, a 40 Amp parallel battery charger for 12 Volt batteries. This multiple charging system can recharge ten batteries (4 amps each) in parallel with easy operation for battery stock maintenance and overnight battery charging. The L1240T also features a 24-hour timer for safe, convenient extended charging.  

Scientists have discovered that defects in carbon nanotubes could lead to supercapacitors that could possibly be used for improving charge and energy storage systems in portable electronic devices such as cell phones. Mark Hoefer, a University of California San Diego (UCSD) materials science grad student, and mechanical engineering professor Prabhakar Bandaru, made the discovery. Bandaru, along with graduate student Mark Hoefer, have found that artificially introduced defects in nanotubes can aid the

WASHINGTON, Nov 19, 2009 /PRNewswire-FirstCall via COMTEX/ -- While it may not be possible to put "peace on Earth" on holiday lists this season, thanks to YoGen((R)), an innovative product from Easy Energy (OTC Bulletin Board: ESYE), one can still give the gift of "peace of mind!" The world's first fully-sustainable, handheld charging device, YoGen connects to many small personal electronic devices known to man. Through repeated pulls on the attached ripcord, similar to the motion of a yo-yo, YoGen genera

One of the most frustrating things we face is when a dead battery shuts down our technology. With the new YoGen universal charger, this problem is now a thing of the past.   -Guy Ofir

 

Here's a great way to avoid changing batteries in your remote control: use a remote it doesn't need any batteries at all. This design concept by NEC and Soundpower uses the vibrations of your fingers pushing the buttons to power a volume control, channel switching and on/off. Sure beats operating a remote with a hand crank .  

Two electrical engineering students at Nairobi University, 24 year old Jeremiah Murimi and 22 year old Pascal Katana, have developed an innovation to literally bring power to more people in Kenya. Using salvaged parts from old televisions and radios, the duo retrofitted the dynamo attached to all bikes sold in Kenya so that cyclists can charge their cell phones as they ride. Of Kenya's 38.5 million people, it is estimated that roughly 17.5 million own a cell phone.
