New Battery Tech That could let you talk for days

A new technology using silicon nanowires would increase the capacity of rechargeable lithium-ion battery to store charge up to a factor of 10, according to research conducted at Stanford University.

The technology could significantly extend the operating time of battery-powered devices like digital cameras, iPods, mobile phones and notebook computers from a minimum four hours to a full day or an entire work week.

This achievement is the upward trend for lithium-ion batteries, but a revolutionary one, according to Yi Cui, assistant professor of Materials Science and Engineering and lead researcher.

"If the allegations are true, this could be a breakthrough technology," said Roger Kay, president, Endpoint Technologies Associates.
Increased capacity

Standard lithium-ion batteries use graphite anodes that are able to hold only a limited amount of charged particles of lithium. The limited capacity of graphite anodes is essentially responsible for the relatively short life burden of lithium-ion battery. The replacement of graphite anodes with silicon nanowires to increase charge capacity of the storage battery, the Stanford researchers found.

"Silicon is an attractive anode material for lithium batteries because it has little chance of discharge and the highest known theoretical charge capacity," the report says.

However, the researchers needed to solve a longstanding problem surrounding the use of silicon in lithium-ion batteries. The repeated import and export of lithium ion causes tiny silicon wires to degrade and eventually be dissolved, which leads to poor battery performance Click here to learn how the AT & T Application Management can help you focus on the development and the profitability of your business. long term.

"Although [the ability of silicon] is more than 10 times higher than existing graphite anodes and much larger than various nitride and oxide materials, silicon anodes have limited applications Click here to learn how the AT & T Application Manager you may help to focus on growth and profitability of your business. because changes in the volume of silicon by 400 percent in import and export of lithium, resulting in pulverization and capacity fading, "the report explains.
The Solution Steel

Cui, together with colleagues of the researchers, solved the problem by growing silicon nanowires directly on a substrate of stainless steel, which served as current collector, the report says. The nanowires were able to inflate up to four times their normal size - one millimeter thickness of a piece of paper - which absorbed lithium is not any breakage.

The anodes were then able to achieve the maximum theoretical charge capacity of silicon for the first cycle of charge and remained close to 75 percent of maximum during the numerous charge and discharge cycles, according to researchers.

The new lithium-ion batteries could be available within several years.

"This could make a big difference in many possible applications, if the benefits can be carried all the way through the process at a reasonable cost," Kay told TechNewsWorld.

Alcatel Kicks Off Project to Make Telecom Nets 1,000 Times Greener

Alcatel-Lucent Bell Labs launched a Green touch, a project aimed at making communication networks 1,000 times more energy-efficient.

Founding members of the project include service providers such as AT &T; research laboratories such as MIT Research Lab for electronics and Bell Labs? And the government and nonprofit research institutions such as the French National Institute for Research in Computer Science and Control.

The project hopes to deliver a network architecture reference to prove the essential elements required for it until 2015.

Reach Out and Green Something
Green Touch bases 1000 times better energy efficiency research Bell Labs. The laboratory analyzed the information and communication technology (ICT) networks, technologies and architecture.

Bell Labs then applied the Shannon-Hartley theorem of its findings. Roughly speaking, the theorem describes the maximum bandwidth available for transmission by adding the value of the signal encoding and the value of noise or interference.

Founding members of the Project Green Touch from various countries. Service provider members include AT & T, the China Mobile, by Portugal Telecom, Swisscom, Switzerland provider, and global telecommunications giant Telefonica. Members of the academic research laboratory is the MIT Research Laboratory of Electronics, Wireless Stanford University in Systems Laboratory and the University of Melbourne Institute for broadband-enabled society.

Government and nonprofit research institution shall be the CEA-LETI Applied Research Institute of Microelectronics and the French National Institute for Research in Computer Science and Control (INRIA). Industrial members of the laboratory, except for Bell Labs is the Samsung Advanced Institute of Technology and Freescale Semiconductor.

The project has also received expressions of support from the United States Energy Secretary Steven Chu and the British, French, South Korea and Portugal.

The Green Touch Vision
By 2015, the Green Touch Project aims to deliver the architecture, standards and roadmap to reduce the energy consumption of communication networks at the rate of 1,000 per user from current levels. It also plans to demonstrate key elements of it.

"It's a really aggressive program," Gee Rittenhouse, head of research at Alcatel-Lucent (NYSE: ALU) Bell Laboratories, told the E-Commerce Times. "We have five years to demonstrate these technologies."

Bell Labs is open for membership of the project Green Touch. Why not get other carriers, governments and organizations on board before the announcement of the project? "It takes a lot of time to plan a project of this size, and much time wasted on this," Rittenhouse explained. "With something that is this broad and complex, rather than trying to work with all elements that will take forever, would be representation from each of the constituencies to our members and, with a smaller group, I can build something that can prove.

It expects membership to grow over time.

We are the green world
The Green Touch project should not have trouble getting buy-in, Rob Enderle, principal analyst at Enderle Group, told the E-Commerce times. "Governments want this trend to a large extent, I would expect that they will have no problem getting on board," he stressed. "It may come to be simply a problem of keeping people who must approve announcements to a manageable level."

VMWare wants to buy Zimbra software from Yahoo

VMware Inc agreed to buy email software vendor Zimbra by Yahoo Inc, as Yahoo continued to sell parts not related to core consumer business on the Web.

The companies didn't disclose the terms of the Zimbra's sale, which makes software for Web-based e-mail and calendar systems that compete with those from Google Inc, the IBM Corp and Microsoft Corp Yahoo paid 350 million U.S. dollars for Zimbra in October 2007 as part of a takeover move that preceded the arrival of current CEO Carol Bartz, who was hired last year to turn around the company match.

VMware sells the programs used by companies to enhance the efficiency of computer hardware - allowing a machine to perform the work of multiple pieces of equipment. Programs also help companies manage complex data centers.

Jefferies & Co analyst Katherine Egbert said he saw how the line Zimbra email and calendar software will complement the existing products of VMware.

VMware, which is majority owned by EMC Corp, said the acquisition is expected to close in the first quarter of this year.

Wireless charging, iPhone TV and more gadtes at hot gadges show

At the International Consumer Electronics(ICE) Show last week, 3-D television, electronic readers and small laptops captured much of the attention.

There were plenty of other interesting ideas on display, also, from 3-D printing for cell phone wireless tether. Here are some of the gadgets are expected to keep out even for this year, and even some of the best eyebrow machicolation of play:

TV on the iPhone - Qualcomm Inc. 's FLO TV service has been limited by the fact that only a few AT & T Inc. and Verizon cell phones to receive the wireless signals, to about 15 news, sports and entertainment channels. Now, Qualcomm has teamed up with phone maker Mophie Accessories create an external battery pack for the iPhone that doubles the FLO TV receiver. This is expected in the first half of the year.

Game-controller glove - Iron Innovations have shown a futuristic-looking black-and money-center glove and keyboard that lets users control games by Touching fingers together instead. Called the Fabhcún, the glove includes five sensors on each finger to replace different keystrokes when she contacted a glove to the thumb.

Wireless charges - Last year, showed off a Powermat U.S. MAT gadgets were being charged because it - as long as the gadgets were fitted with special covers.

Polaroid Instant Cameras - Polaroid stopped making the instant film two years ago, but brave group of enthusiasts and bought one of the former Polaroid factory in the Netherlands and reinvented the film. A film is expected on the market later this year, and to go along with, Polaroid announced at the show that it will bring back instant film cameras.

The cell-phone tether - losing your cell phone to draw, and called Zomm body believes it can make the thing on the past. It is a small device, also known Zomm, that wireless connection to your phone via Bluetooth and sets out the alarm if you walk out of it.

-3 D camera - the world pressure from makers of television sets that year to show 3-D on the town. Fujifilm, betting that people want to shoot their own 3-D movies and photos as well, is to sell as well as digital camera with two lenses, a set rather than as if they are human eyes.

3-D filter - What if you want 3-D scenes, but you are not trying to get a new 3-D television and Blu-ray player? Realview Innovations Ltd. It all worked out for you. The Irish company has developed the film over can be set to make it look as flat on the surface of the screen bulges inwards.

3-D color printing - Shapeways is offering 3-D print for several years, providing data files and turning them into sculptures with the help of a machine set down together layers of plaster-like material. At the show, the Dutch company announced that they are now offering sculptures in full color.

Mopping robot - it is the battle of the cleaning robots! The robots Roomba vacuuming will get competition this September from the Mint, a square that eochaircheap register for Swiffer dry or wet-type cleaning cloth.

Nexus One's hardware's cost estimated to be $175

Upcoming Google Nexus One smart phone consists of shares worth about $ 175, according to a tear down of the iSuppli.

The new phone, which Google unveiled, offers a less developed by Google and the external design of HTC. The main interface is a 3.7-inch AMOLED display. The Nexus One runs Google Android operating system 2.1, and WVGA display appeared 3G graphics.

While Google has priced at Nexus One at $ 179 with a two-year T-Mobile service plan ($ 529 without the subscription plan), the phone numbers of the material for $ 174.15, according to iSuppli analysis, which was posted Friday. The report stated that his plan does not include other costs such as production, packaging and software.

"Things like that durable unibody construction, a blazingly fast Snap Dragon base band processor and bright and sharp Active Matrix Organic Light-emitting Diode (AMOLED) displays all have seen on previous phones, but never before combined in one design," Kevin Keller Senior Specialist in iSuppli, said in a statement.

Most animals in the 17-bit in HTC-built phone is 1 GHz Qualcomm Snap Dragon's processor, which rings in at $ 30.50, or 20 percent of plan iSuppli Bill of materials. Snap Dragon debuted in February 2009 in Toshiba TG01, which is based on Windows Mobile. But iSuppli found ARM-based processor to be better in the new Nexus One.

The Android 2.1 operating system is used in the Nexus One better capitalizes on fast performance Snap Dragon is, the user interface and applications run very fast, "Keller said." This processing muscle also gives Nexus One key capabilities, especially the high-definition 720p video playback. "

Next expensive component is Samsung's 3.7-inch AMOLED display, which lists at $ 23.50. iSuppli notes that the AMOLED technology appears before the Samsung's Android-based I7500 with a 3.2-inch AMOLED touch screen.

"The 3.7-inch AMOLED display at Nexus One delivers a stunning picture," Keller said.

Rounding out the three most expensive part in the Nexus One is Samsung's 4Gbit (512MB) of DDR DRAM, which costs $ 20.40, or about 11 percent of the estimated cost iSuppli today. iSuppli notes that comparable smart phones generally contain not more than 2Gbits of DRAM, but to increase the memory to allow for better application performance.

Honda's hybrid CR-Z to arrive in a few months

Honda Motor touted its Hybrid CR-Z 11th january,Monday, debuting the production version of the two-door, two seat COUPE and said it because going on sale soon.

The Hybrid CR-Z is to "establish a few months," said Honda CEO Nobu Taka Ito at a press conference here in the North American International Auto Show.

He was an engineer working in 1980 on the ancestors, the "Pocket Rocket" CR-X, and said that the new model is designed with similar objectives to be fun and fuel-efficient.

The car combines a 1.5-liter, four-cylinder engine with 10-kilo watt electric motor to deliver 122 hp at 6000 rpm, Honda said. Fuel economy, estimated fuel economy is 36 km from the gallon and 38 mpg for city and highway driving the model with continuously variable transmission, six-speed manual is down to 31 mpg city and 37 mpg highway by EPA standards.

Electronics equipment figure prominently in the CR-Z. It comes standard with six-speaker AM / FM / CD / USB audio system, remote keyless entry, and Cruise Control. The higher-end EX models come with Bluetooth link and subwoofer-equipped 360-Watt premium audio system. A Satellite-linked navigation system with voice recognition is option.

Security features of the car has six airbags and anti lock brakes, with him.

While Honda is getting more serious with its Hybrid system, his heart lies with vehicles powered by hydrogen fuel cells, which Ito called "The Ultimate Eco-car."

"We continue to believe fuel cell electric vehicle is the ultimate solution to reduce emissions of carbon dioxide,"Mr. Ito said.

Fuel-cell power company's FC-X was on the screen, and Ito announced a next generation in home hydrogen fueling station to a lack of compressor, can "fit in perfectly with the garage user," he said.

But in the near term, Honda is supporting Hybrid Electric vehicles and aspires to make them compact, lightweight and affordable. Honda plans to release a hybrid model Acura, Ito said at the conference.

McDonald's to start free Wi-Fi in its U.S. stores from 15th january

McDonald's Corp. plans to offer free Wi-Fi service in most of its U.S. restaurants, which began on January 15, a spokeswoman said.

The largest U.S. fast-food chain had said it would provide free Wi-Fi at some point in early 2010, but had not given today.

A McDonald's spokeswoman told Reuters that free Wi-Fi will be available for 11,500 in its total of 14,000 locations.

The company currently offers Wi-Fi for rate $ 2.95 for two hours, she said.

Analyst firm said that tech sector is recovering in 2010

The technology downturn is over and that recovery is underway after the "dismal" in 2009, where companies keep spending on computers and software, according to new analysis.

Forrester Research Inc. was set to report on last Tuesday(15 th january) that it expects global spending on technology products and services to grow 8.1 percent in 2010, more than $ 1.6 trillion. U.S. spending is expected to increase 6.6 percent, to $ 568 billion.

This project increases the sharp decline in 2009, when companies and governments slashed purchases of PCs, computer peripherals and communications equipment to deal with economic turmoil and credit crisis. Many large technology companies such as Microsoft Corp., remained profitable and increase their stock prices in 2009, but often they rely on layoffs and reduced costs to do it.

Even with the expected rebound, "the level of computer equipment purchased in 2010 will still be lower than in 2008 or even 2007," said Forrester analyst Andrew Bartels.

With the recession over, pent up demand for new computers and upgrade program is to benefit the companies who make them. October launch of Microsoft's latest PC operating system, Windows 7, also gives companies a reason to start replacing computers.

Still, Forrester warned that growth will start slowly and pick up later in the year.

The research firm also expects spending money on communications equipment to pick up this year, partly because demand in the coming markets are building wireless and broadband networks.

Forrester is not alone in predicting a rebound for the year. Autumn Gartner Inc. predicted 3.3 percent growth in global technology spending. Another analyst firm, IDC, said in December that global technology spending would grow 3.2 percent in 2010, again the industry to 2008 levels of about $ 1.5 trillion.

More insight into recovery in the labor market is coming Wednesday, with the release of figures on sales PC in the fourth quarter and on Thursday when Intel Corp. reports earnings for the period

"India can be solar power leader" said by Indian PM ,Manmohan singh

Indian Prime Minister Mr. Manmohan Singh Ji set out ambitious plans for that country in the world's leading solar power on Monday as the government launched an initiative to increase the use of technology.

Solar energy India to secure independence and tackling climate change, "said Singh, as well as new opportunities for the industry in a country with a crippling lack of power.

The National Solar Mission, launched Monday, could "establish India as a world leader in solar energy" in the following areas: energy production and production technology, Singh told business leaders and government officials.

"The rapid spread of solar lighting systems, solar water pumps, solar energy and other rural-based applications can change the face of rural energy," he said.

Solar mission is growing exponentially to reach 20,000 megawatts of solar capacity in the year 2022, reducing reliance on fossil fuels.

This amount would provide enough power 20 million homes, each received a kilowatt of energy.

Government figures showed more than 80,000 impoverished Indian villages didn't have access to the electricity network.

India currently produces nearly nine megawatts of solar power, data from the Ministry of New and Renewable Energy (MNRE) compared to October.

The Prime Minister said India boasted some of the world's largest science and technology, and there was no revolution in the minds of nuclear energy, space and information technology.

"I am convinced that solar energy could be the next frontier in science and industry in India," he said.

Indian companies, which may qualify for one of the push Tata BP solar, which is a joint venture between Tata Power and BP Solar India and one of the leading solar distributors.

India for more than 15,000 megawatts of renewable power for all by the MNRE, more than 10,000 megawatts from wind power alone.

India is Developing its own Anti-Satellite Spacecraft

ndia began the development of lasers and an exo-atmospheric kill vehicle with a weapon that could destroy enemy satellites in orbit, the Director-General of the Indian defense research organization, said January 3

"The kill vehicle, which is needed for listening to the satellite, to be established and that the work is done as part of a ballistic missile defense program," said VK Saraswat, Director of Defense Research and Development Organization, which is part of the Indian Defense Ministry.

During a televised press conference 97 Indian Science Congress, Thiruvananthapuram, Saraswat said the program also includes the lasers', which can give you a concrete picture of the satellite and use the picture to fly the vehicle, that it kills. The work that still needs to be done. "

India is not the first country, which has announced plans for anti-satellite spacecraft. In 2007, China deliberately destroyed an old weather satellite during an anti-satellite evidence that created a swarm of debris in orbit above Earth.

The United States has successfully destroyed a crippled spy satellite in 2008, an SM-3 missile was launched a naval vessel. That the satellite was ordered to kill, to destroy the falling satellite, to avoid the toxic debris falling down part of U.S. military officials said.
