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. Another potential source of energy could be piezoelectric energy. When mechanical stress is applied to certain materials, charge is produced that can be converted into energy, called piezoelectric energy. Piezoelectric materials have the capability to harness energy from vibrations. Although we all are aware that the power levels would be low, researchers claim that the environmentally friendly technology will be replace batteries without any added costs. The power demands of the future world are expected to exceed manifold and to cater to needs we need to develop as many sources as possible. 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. The units are only suitable for equipment with low duty cycles, such as remote controls and provide about 100-mW of power, while remote controls typically consume between 40-mW and 100-mW when in use, the report said. Tesla Plans Model S Battery Swap as Fast Refueling Option. Tesla Motors Inc.
(TSLA), already adding a network of fast-charging stations for its luxury electric cars, is readying a service to rapidly swap a car’s battery with a charged pack for added convenience. The company, based in Palo Alto, California, announced last week plans for a June 20 press conference at its design studio in Hawthorne, California, to show “a way for the Tesla Model S to be recharged faster than you could fill a gas tank.” Chief Executive Officer Elon Musk, in a Twitter post today, said the event would feature a “live pack swap” demonstration at 8 p.m. California time on June 20. Energy-Generating Knee Strap Could Spell the End of Batteries. Photo by Shutterstock Time for the energy industry to pull itself up by the knee straps: A group of scientists in the United Kingdom have developed a novel energy-harvesting device that attaches to the joint between the thigh and shin. Composed of piezoelectric materials , which generate power when they’re subjected to mechanical strain, the technology could spell self-powered heart monitors for athletes, lighter loads for soldiers, and gadgets that won’t run out of juice before you do.
The research, published in this month’s issue of , combines the expertise of scientists from Cranfield University , the University of Liverpool , and the University of Salford . The device itself is circular, with an outer ring and a central hub. When the knee joint goes through a walking movement, the outer ring rotates, causing the 72 plectra on its surface to “pluck” four energy-generating arms on the inner hub. The best part?

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. The battery is now compatible with these cards, the types that may serve as credit cards, subway and train passes, or as hotel door-keys. The envisioned ultra-thin, flexible plastic credit cards may not appear commercially this year but reports say that NEC intends to have ORB incorporated in products in 2013. 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. Dual-charged Approach to Battery Testing. Researchers produce power from engineered virus. Thursday, 17 May 2012 08:09 News & Events - Engineering News May 17, 2012 It's not all that uncommon to hear energetic people described as dynamos, and any given person consumes and uses plenty of energy throughout the day.
Fail: Green car battery maker goes bankrupt. 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. Ambient energy sources can be broadly divided into direct current (DC) sources and alternating current (AC) 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. 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. Now the Commission is going after the devices that recharge the batteries for your ever growing collection of portable electronics, from cellphones to music players, laptops to power tools. The average home now has 11 battery chargers, according to Commission spokesman Adam Gottlieb. 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.
