A 2,000 YEAR OLD ELECTRIC BATTERY. Piezoelectric energy can potentially replace batteries in future. Piezoelectric energy can potentially replace batteries in future Alternative energy industry, as we all know, is growing exponentially.
Till now we have successfully produced energy from fossil fuels, petroleum, coal, etc. And, when we realized that these sources are finite, we started exploring renewable sources like wind, solar power, tidal and geothermal power. Vibration harvesters designed to replace AA, AAA batteries. To illustrate the application of vibration-powered electricity generators the example is given of installing them in a remote control for a television or set-top box, where it is possible to use the remote after shaking it to generate power.
In such applications the use of energy harvesters in AA and AAA formats can eliminate the need to replace batteries and reduces waste. Inside the battery-shaped case is an electromagnetic induction generator and a 500-mF capacitor for storage. The output of the AA-size generator is 10 to 180-mW, the report said and versions have been produced that provide power at 1.6- and 3.2-V, while a AAA unit that generates 2.7-V has also been produced.

NEC goes ultra-thin with 0.3mm-thick batteries. (PhysOrg.com) -- NEC, which has been working on what is called "organic radical battery" (ORB) technology for some years, has announced its latest ORB breakthrough, the 0.3mm thick ORB.
According to Geek.com, the output rated as 5kW/L with a capacity of 3mAh. On full charge, the new battery prototype can refresh a screen 2,000 times. A recharge takes under a minute, about 30 seconds. The new batteries maintain 75 percent of their charge-discharge after 500 charges. NEC has been exploring these polymer-based batteries since 2001, but the battery thickness was limited to 0.7mm. This Paintable Battery Can Be Used Virtually Anywhere.
Researchers at Rice University in Texas have created a paintable battery that can be used anywhere.
Also impressive — the battery is rechargeable and can hold a 2.4 volt charge for six hours. To create this sprayable battery, the team disassembled the chemicals of a lithium-ion battery and converted them into five paints. These paints were then sprayed in a particular order, like a conventional battery cell, onto ceramic tiles. Then the nine tiles were lined up parallel and placed with one tile topped with a solar cell that converted power from a white laboratory light. Dual-charged Approach to Battery Testing. Researchers produce power from engineered virus.

Fail: Green car battery maker goes bankrupt. $55 million in taxpayer money down Obama’s green rathole.
BusinessWeek reports, Ener1 Inc., which owns a company that received a $118 million U.S. Energy Department grant to make electric-car batteries, filed for bankruptcy protection after defaulting on bond debt amid Asian competition.The company listed assets of $73.9 million and debt of $90.5 million as of Dec. 31 in Chapter 11 papers filed today in U.S. Bankruptcy Court in Manhattan. Ener1 has been affected by competing battery developers in China and South Korea, “which generally have a lower cost manufacturing base” and lower labor and raw material costs, interim Chief Executive Officer Alex Sorokin said in the petition.Ener1, based in New York, makes lithium-ion batteries for plug-in electric cars, which were scrutinized by federal auto- safety officials after a General Motors Co.
Piezoelectric materials : Sun Solar Electric. In the last few years, there has been considerable effort by various companies to make “perpetually powered” and battery-free systems which operate from ambient energy. the key integrated circuits (ICs) needed to develop such a system are ultra-low-power microprocessors, radios, and power-management ICs (PMICs).
While considerable progress has been made in the field of low-power microprocessors and radios, only recently have PMICs suited for energy harvesting applications started appearing in the market. This article provides a quick introduction to some of the ambient energy sources available followed by a detailed discussion of factors to be considered when choosing a PMIC for these energy sources. California Energy Commission Adopts New Battery Charger Standards. SAN FRANCISCO (KCBS)— Battery chargers aren’t the most energy efficient devices and their growing presence in homes has a state energy commission concerned.
New rules are being adopted to save consumers on money and electricity. “There are 170 million chargers out in California. Each home has an average of 11,” said Adam Gottlieb with the California Energy Commission. The agency just approved a first of its kind in energy efficient standards for all those cell phone and digital camera battery chargers that keep adding up. KCBS’ Dave Padilla Reports: New Effort to Keep Battery Chargers From Wasting Your Power. It's been dubbed "vampire power"--the electricity that is sucked out of your home by inefficiencies and devices that draw electricity whenever they're plugged in, even when they're not turned on. For nearly four decades, California's Energy Commission has led a crusade to drive a stake into vampire power by setting efficiency standards for a wide range of appliances, from refrigerators to flatscreen televisions.
California even beat the federal government to the punch by a year by moving to phase out the classic 100 watt lightbulb with the improvements in lighting efficiency that have occurred since Thomas Edison's day. How to Conserve Battery Life on Your iPhone. It’s well-known that, with the release of iOS 5, battery life has been less than exemplary. I’ve been slammed with it, too, and am feeling the repercussions when I’m only halfway through the day and I get that dreaded low battery warning on my iPhone — not only my iPhone, but any iDevice has been struck hard for those of us who have updated. Apple has been actively pursuing a solution to the problem and even called complaining owners personally to have them install diagnostic tools for troubleshooting.
Since then, iOS 5.0.1 has been released to combat the problem a little bit, with a full solution promised in an iOS 5.0.2 release soon.
