A small portion of consumers are fairly dedicated

May 09 [Thu], 2013, 18:25
A few days ago we reported on the issue of standby power–that our homes and workplaces are populated with electronics that often consume energy even when they’ve been turned off. Nationally,such secretive parasites add 5-10% to our total electrical consumption.At the global level,one of the biggest culprits are cell phone chargers.Without diving into a nerdy discussion of electrical enginee 42T5263 brightring,most chargers use essentially the same amount of power regardless of whether they’re recharging batteries or sitting idle.


In fact,the lion’s share of a mobile battery carbon footprint lies not in the energy required to charge its battery,but in the endless hours that its charger will spend plugged into an outlet doing nothing.A small portion of consumers are fairly dedicated about removing their chargers from the outlet when it’s done,but most are simply unaware of the problem.Then there are those not unlike myself,who,however well intentioned or conservation-savvy,have occasionally forgotten to unplug said cell phone charger only to realize their absentmindedness many days,and watts,later.

Whatever group of consumer you fall in,there’s good news as AT&T’s ZERO smart charger has announced that it will be offering a smart charger for its US customers at “dumb” charger prices.This is particularly good news for iPhone and Blackberry owners seeking to keep their carbon footprint as trim as possible.If the whole issue of fretting over cell phone chargers sounds trivial,keep in mind that there 51J0497 bright are an estimated 4.6 billion cell phones in use around the globe.


The good news about Going Green is that lowering your carbon footprint = saving money,not the other way around.Just like the smart chargers, our expertise lies in delivering to you the necessary information to intelligently lower your energy usage (and without having to give up your car or electricity.)

Lithium-ion batteries on the market today

May 09 [Thu], 2013, 18:24
The group developed a new method for boosting battery efficiency, which relies heavily on the use of a bi-dimensional carbon compound called graphene. The material has a hexagonal structure, and boasts impressive L08S6D13 bright chemical and physical properties.

Currently, graphene is not widely used because obtaining it is a very complex process. However, recent advancements in manufacturing techniques are bringing the material closer and closer to being available on a large scale.


As this happens, we can expect to see more and more researches based on its properties. For the latest one, NU experts decided to improve on past designs that called for graphene to be introduced in Li-Ion batteries. The team says that its new power storage devices recharge 10 times faster than any other.

Investigators published their research in the latest issue of the esteemed scientific journal Advanced Energy Materials. “We have found a way to extend a new lithium-ion battery’s charge life by 10 times,” reports the lead author of the new paper, Harold H. Kung.

“Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today,” adds the expert, who is a professor of chemical and biological engineering in the McCormick School of Engineering and Applied Science.

The new batteries, he explains, feature anodes made up of silicon and graphene. The former is known for its ability to store 4 lithium atoms for each silicon atoms, but is highly unstable as a result. Graphene holds 1 lithium atom per six carbon atoms.

By combining the two chemicals, the research team managed to successfully obtain the best of both worlds. “We have much higher energy density because of the silicon, and the sandwiching reduces the capacity loss caused by the silicon expanding and contracting,” Kung says.

“Even if the silicon clusters break up, the silicon won’t be lost,” he goes on to say. The main issue silicone anodes have is that they tend to contract and expand with each recharge cycle. This leads to fragmentation L09S6Y02 bright and loss of charge.

The NU team now plans to continue developing this new approach to manufacturing lithium-ion batteries. Experts hope to bring the approach to the market as soon as possible.

The lithium-oxygen bonds break

March 21 [Thu], 2013, 17:03
Electric cars face severe limits in how far they can drive before running out of juice. Better batteries that can both store more energy and give it up quickly are essential for extending that range. Now, researchers at the Massachusetts Institute of Technology (MIT) in Cambridge have come up with a novel battery-making12 cells HSTNN-OB42 strategy that steers in that direction. For now, the new batteries can power only small devices. But if the strategy can be made to work on a larger scale, a task more difficult than just using more battery material, it could give electric car makers the jolt they need.

Today's most popular rechargeables, lithium ion batteries, are made from negative and positive electrodes separated by an electrolyte through which positively charged lithium ions can flow back and forth. In most such cells, the negative electrode is made of graphite, a form of layered carbon, whereas the positive electrode is made from lithium cobalt oxide or a related material. During use, lithium ions stored in the graphite flow to the lithium-based electrode, where they form chemical bonds with oxygen atoms, a reaction that generates an electric current. When the battery is recharged, the lithium-oxygen bonds break and an electric voltage pushes the ions back into the graphite.

Researchers have long sought to replace the graphite in the negative electrodes with carbon nanotubes, strawlike tubes of carbon. The hope is to create a more porous material with a higher surface area that could hold on to more lithium ions and thus make longer-lived batteries.

But in a paper posted online today in Nature Nanotechnology, the MIT team, led by materials scientist Yang Shao-Horn, took a very different approach: using carbon nanotubes to replace the oxide-based positive electrode. Normally, lithium ions wouldn't bind to plain carbon nanotubes. So Shao-Horn and her colleagues decorated the outer surfaces of their nanotubes with two different types of oxygen-containing chemical groups that gave them opposite charges. They then dipped their electrode starting materials alternatively in solutions containing the oppositely charged nanotubes, binding successive layers of tubes atop one another to build up their nanotube electrodes.

The result was a highly porous carbon nanotube electrode with lots of oxygens exposed on the surface, ready to bind with lithium. Detailed tests showed the new batteries hold five times as much energy as conventional quick-discharging devices called capacitors do, and they deliver that power 10 times as quickly as conventional lithium ion batteries can.

"This is certainly pioneering work," says Ray Baughman, a chemist at the University of Texas, Dallas. Baughman cautions, however, that the MIT team achieved its best results with very thin electrodes. The performance dropped off12 cells HSTNN-OB60 considerably as the electrodes were made thicker. Because thicker electrodes can store more charges, they allow a battery to hold more energy.

So for now, hybrid batteries will be best suited to applications with low overall power demands, such as powering electronic circuitry in smart cards, credit cards with electronic chips that hold more information than magnetic strips do. For the batteries to be useful in hybrid cars or other power-hungry applications, researchers will need to find a way to make thicker electrodes that can still move charges quickly, a project Shao-Horn says she is working on now.

Keep the battery always charged for if it is kept drained too much

November 16 [Fri], 2012, 17:46
Although disposable, this battery is the most common type used in small household gadgets such as remote controls or 12 cells VGP-BPS13/Q -operated toothbrushes. They were popular back in the 1970's, and are substituted in place of the Carbon Zinc and Zinc Chloride batteries.

They are not ideal to use for digital cameras since they do not have good power surges. They still work, but its life will be short. Some manufacturers have made alkaline batteries, however, that can work well in high drain devices. They include Duracell Ultra, Energizer Advanced Formula, and Kodak Photolite.

Take note that there is not much difference from brand to brand since each battery uses the same chemicals. Comparison tests was done by Consumer Reports between different alkaline brands and showed that the best and worst batteries only differ between 9% - 15%.

In 1996, Congress banned the production of alkaline batteries containing the toxc metal mercury for obvious reasons, one being it is not safe to throw away in the trash bin. Now it is safe to do so with then exceptions of the button batteries, the ones found on wrist watches. Although there are special electronic cheap VGP-BPS13A/B places that takes in those batteries and safely disposes them.

Even though it is not recommendable to recharge alkaline, it is possible, provided that the right rechargeable device is used. If NiMH or NiCad recharger is used, the batteries may explode, especially with the newer high-drain alkalines which is resistant to recharging. Standard alkaline batteries get lesser recharge cylcles than the rechargeable ones. It is recommended to keep the battery always charged for if it is kept drained too much, it may not be possible to recharge it.

Examples of Rechargeable batteries include Pure Energy and Accucell

November 16 [Fri], 2012, 17:43
These batteries were supposed to bring the best of both worlds for alkaline. Its high capacity combined with its rechargeable nature makes is sound very good. However, it does not. Rechargeable Alkalines get fewer recharge cylcles in comparison to NiMH rechargeables. In fact, the Rechargeable Alkalines have rn873 a1245 laptop battery high quality a1321lower starting capacity than the best NiMHs anyway.

Rechargeable Alkalines cannot be used in digital cameras since it is not a high-drain battery, and it also requires a special charger.

However, Rechargeable Alkalines do give out higher voltage than NiMH. This means that it performs great with devices that take in multiple batteries. For instance, LED flashlights gives out brighter light with the alkalines than with NiMH. With the infrequent use along with high self-discharge of the NiMH makes the batteries go dead on their own between periods of use.

Examples of Rechargeable batteries include Pure Energy and Accucell.

As mentioned with the regular alkaline, DO NOT charge batteries with any regular recharger for they may explode. Always keep the batteies "topped off" meaning the sooner it is recharged, the more recharge cycles and more total power it can give throughout its lifetime.

There are no 9V rechargeable alkalines for two reasons. One being that they are made with six 1.5V-cells inside, therefore making it easy to access each cells for and reliably recharge them. It is harder to access the cells 12 cells a1322with the 9V. The other reason is that 9V batteries provides limited benefit in terms of cost savings for the products that run with them lasts more many months anyway.

The company operates the only free battery and cellphone collection program

October 19 [Fri], 2012, 17:22
Household batteries, which contain toxic metals like mercury, lead and cadmium, are now being collected for recycling under the firstcheap Presario CQ50 battery government-sponsored program in North America.

B.C.'s Minister of State for Climate Action John Yap and Call2Recycle CEO Carl Smith announced the partnership Tuesday.

Household batteries, including alkalines, can be dropped off at any of the 1,500 locations in B.C. where rechargeable batteries have been collected since 1997. A locator on the company's website at call2recycle.ca also lists the collection sites, several of them in the Chilliwack area.

Yap said the B.C. government "fully supports Call2Recycle's efforts to recycle batteries and cellphones into new products and keep them out of our solid waste stream, which will help the environment and the economy."

Smith said recycling household batteries keeps toxic metals out of landfills, but "more relevant" is limiting waste by recycling it into secondary products.

He said the company expects to collect 25 percent of household batteries by 2012 - which sounds low, but not when you figure the majority of batteries are "embedded" in products like powered toothbrushes and iPods.

Call2Recycle recovers the metals from Compaq envy Presario CQ56 battery and sells them to secondary manufacturers - but the majority of its financing comes from fees paid by the battery-makers, Smith said.

The company operates the only free battery and cellphone collection program in North America, and has diverted more than 25 million kilograms of rechargeable batteries from landfills since it was formed in 1994.

The first thing to consider for the laptop adapter is the voltage

October 19 [Fri], 2012, 17:20
Choosing the correct laptop adapter is all a matter of voltage, output power, and proper connection. If all of these things do not match the original specifications of your computer, than a new laptop adapter will likely not work on your machine and may potentially cause a lot of damage. In the end, most replacement 9cells Presario CQ43 batteryadapters will have a list of computers they are compatible with.

The first thing to consider for the laptop adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V attached to it, such as 19.5V. This information is also available on the original adapter, if it is available.

The second thing to look for is the current output needed for the laptop adapter. This number will have an A of mA associated with it. For example, it may say something like 4.7A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

Product ID: ANB002C7U, Input volts: 100V-240, Input Frequency: 50 ~ 60Hz, Output volts: 19 V, Output Current: 4.74A, Power: 90 W, Battery Weight: 652.05 g.

Once these two issues have been settled, the other important step is simply to make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the laptop adapter will not matter if it is not able to be connected. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.

Many may choose the safest route possible and go with a replacement laptop adapter directly from the manufacturer, if available. While this is a good option, these parts may be more expensive than others that may be available from 12 cells Presario CQ45 batteryafter-market manufacturers. Further, as long as the numbers match, all should work nearly the same and be just as safe and effective.

Another thing to consider is whether you want an AC laptop adapter or DC adapter. An AC adapter is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapter is made for automobile use.

Li-Ion as the best type of battery available for your laptop

September 08 [Sat], 2012, 11:19
When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop replacement battery for pa3536u-1brs; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.

The nickel cadmium battery, known as NiCad (pronounced "Nigh-Kad"), used to be the most common type of laptop battery. Nickel cadmium batteries couldn't hold very much power by today's standards, and could only be charged a limited number of times. NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the "memory effect," meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it.

The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect -- although it wasn't as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn't have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.

Regardless of which type you have, it's important to properly care for your laptop battery, in order to get as much life out of it as possible. "Conditioning," which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery. Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it's a good idea to condition all laptop batteries regularly, rather than simply high quality pa3534u-1brsleaving them plugged into the wall at all times.

Your laptop battery should never be stored in an area that drops below 50?oF (10?oC) or rises above 95?oF (35?oC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled. Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.

Nickel in NiMH batteries and cobalt in lithium-ion batteries have intrinsic value

September 08 [Sat], 2012, 11:17
Many communities allow single-use batteries, made without mercury since 1996, to be plaed in household trash. One notable exception is California. The state still regards all batteries as hazardous waste and requires them to be either recycled locally or taken to:

a household hazardous waste disposal facility
a universal waste handler (e.g., storage facility or broker)
an authorized recycling facility.
Are 11.1v 5200mah 9cells pa3727u-1brstruly recycled—meaning that their materials are reclaimed for use in the manufacture of other products? Paul Schneider, director of sales and marketing for Kinsbursky Brothers, a waste-materials recycling specialist based in Anaheim, Calif., says rechargeable batteries are definitely recycled. It's a different story for single-use batteries, though. While recycling technology is available, he says, it is rarely used because little economic incentive exists to use it.

"Nickel in NiMH batteries and cobalt in lithium-ion batteries have intrinsic value," Schneider says. "There's not much demand for what's in alkaline batteries. We send them to our partner in Canada, Toxco, which replacement pa3535u-1brsrecycles them for us. When alkaline batteries are collected in most local communities, they're usually sent to a hazardous-waste landfill." This reality presents another reason to seriously consider using rechargeable batteries.

Solar energy is heavily dependent on the surrounding conditions

July 05 [Thu], 2012, 14:59
If you can be peaceful and safe use of nuclear power really can bring about more possible and convenient. Recently, the 242nd National Meeting & Exposition in Denver at the American Chemical Society (ACS), U.S. Department of Energy's Idaho National Laboratory scientist James Wona Er said that NASA and the U.S. Department of Energy is currently working on a mini nuclear power plant, suitcase-sized. This mini nuclear power plant will be mainly used in space, the future of mankind on the moon, Mars and other planets perform unattended tasks or colonial, it can provide 9cells 590543-001 power at the same time, if the spacecraft can not use solar, mini nuclear power plant will send in handy.

Mini figure as large

James Wona Er is the person in charge of the U.S. Department of Energy Idaho National Laboratory space nuclear reactor project, the lab is mainly responsible for the design and development of nuclear reactors, fuel research and development, as well as small generators. Wona Er said: "Currently, nuclear power plants on Earth hundreds of thousands of megawatts, but this portable mini nuclear power plant generating capacity of 40 kilowatts. This mini design very suitable for space the nuclear power plant design to such a mini-state, of course there are many differences, and it is awesome mini nuclear power plant more flexible, and can be placed to an uninhabited planet, it is lighter than in the traditional sense of the nuclear power plant , which is suitable for ideal nuclear power plant in space. "

The Wona Er introduced, the reactor itself, the width of only about 1.5 feet (0.46 meters), height of only about 2.5 feet (0.76 meters), only a portable suitcase is so big, but it does not have cooling towers. This new type can be used on the moon, a small nuclear fission systems can produce 40 kilowatts or more power, which is equivalent to the electricity consumption of the eight people on Earth.

According to another report, NASA has for this new nuclear power stations preset a variety of usage scenarios. They can provide energy for oxygen or hydrogen generator, at the same time, you can also charge for manned or unmanned spacecraft. The research team plans next year to this specific demonstration to test this new nuclear power plant performance.

Without the risk of core melt

Nuclear power plants is a controversial topic recently, especially the Japanese nuclear accident occurs that causes people to have more to talk about nuclear safety. "Wona Er said:" This mini nuclear power plant risk of core melt, because of the low power generation level, which is quite safe if we really encounter power generation failure, then the reactor automatically shut down. "

Although the United States Space Agency has been suspended for the next shuttle launch, but Wo Naer not worried it will affect the future of mini nuclear power plant because of the extensive use of the small nuclear power plant. Project confidence in NASA's future day this device will be applied to actual space missions, each astronaut should be good news and a memorable day. "It is reported that, In 2005, the United States, "found that the thermal tiles and insulating foam shedding" liftoff, NASA announced the suspension of future shuttle launch. NASA said insulating foam shedding does not cause damage to the "discovery", but the issue is resolved, NASA will not launch the space shuttle.

Wona Er said: "The main thing is such a small nuclear power plant for the astronauts to provide a stable, adequate generating capacity and nuclear power technology is mature, affordable, and safe. The development of this technology validation, cost-effective , which will become the most popular choice for long-term space exploration project to provide electricity resources. "In addition, the Wona Er mentioned, which involves the heat of the reactor is converted to electricity technology. Currently, NASA is testing the status of the Stirling engine under different circumstances, in particular, is introduced into the suitcase-sized nuclear power plants.

Nuclear power use is broader than the solar

At present, the astronauts use a solar cell for spacecraft and devices powered by the conversion of light energy into electrical energy. However, in the outer space environment, solar energy can not exist at any time, and instability.

Sun light and fuel cells are usually the main power generation equipment for space missions, but engineers found that the lack of which, because solar power has its limitations. Solar cells to provide energy, but nuclear power can provide the required generating capacity on other planets near Earth orbit. Solar and fuel cells can not sustain human to stay long on the required power in the universe. The fuel cell depletion, solar energy is heavily dependent on the surrounding conditions. This small-scale nuclear power plant is the first choice for future space development, nuclear power does not depend on these external conditions, it can generate electricity in other places as the Moon or Mars.

From 1961, the radioisotope thermoelectric generators play an important role in the development of solar energy systems. These are not fission reactors, fission reactors rely on uranium atoms split to generate heat and subsequently converted into electrical energy. The radioisotope thermoelectric generator is based on the decay of the radioisotope plutonium-238 to generate a stable heat. NASA's cheap 593550-001Pluto New Horizons "(Pluto New Horizons) and the Cassini mission" (Cassini Solstice) equipped with a radioisotope thermoelectric generator. NASA spent $ 2.5 billion Mars Science Laboratory (MSL) mission will launch the "curious" rovers to Mars to commence exploration, this task equipped with a radioisotope thermoelectric generator. In fact, the radioisotope thermoelectric generator, while very powerful, but if you want to Mars surface fission reactor will be more powerful, because they can produce more energy. Although solar energy matrix has an important role, but the reactor will be the first choice for future space power.
