Expects the stock market outlook is still large room. Investors are advised to focus on.

Toyota’s January 22, 2010 with the “Japan International Automotive Electronics Technology Exhibition” and the “EV and HEV Drive System Technology Show (EV JAPAN)” (1 20 ~ 22, Tokyo Big Sight International Exhibition Center, the organizer: Reed Exhibitions Japan) at the same time holding the technical seminar, on the company’s lithium-ion rechargeable battery delivered a speech on the development trend.

Toyota’s HV Materials Technology Department Minohara Hung-Min to “Toyota’s HV with rechargeable batteries and Development Trends” in the title, first of all a brief introduction of the Toyota’s environmental program and the nickel-metal hydride (Ni-MH) battery replacement situation, and then focuses on The company’s lithium-ion rechargeable battery development program.

Toyota’s lithium-ion rechargeable battery was first applied to the “Yaris (Vitz)” no-idling vehicles, from February 2003 to December 2008, a total of 4900 group produced. The current monthly production of 60 ~ 100 groups. Each cell group consists of four unit structure, cell voltage of 3.6V, current capacity of 12Ah, power density 2250W/kg, the energy density of 74Wh/kg.

The company started from the end of 2009, “Prius plug-in hybrids,” is equipped with a hybrid car is currently being developed lithium-ion rechargeable battery. This although not open the battery of specific targets, but said before the adoption of real vehicle is equipped with five locations around the world conducted a three-year evaluation of the durability testing, has confirmed that no problem.

According to reports, the test is to use the 150 test vehicle in Japan, the United States, Canada, Germany and Spain, and the total travel distance of about 10.5 million km. Vehicles traveling from the furthest traveling in the United States had 57 million 4000km. In addition, some vehicles is also envisaged that most of the time in parking situation, only moving a few hundred km. Toyota Minohara indicated that through -30 ~ 40 ℃ ambient conditions of the test, “was finally developed to meet all the requirements of lithium-ion rechargeable battery.” Battery deterioration Minohara also said, “We had a period of three years, more than 500,000 km driving distance of the inner resistance of evaluation, to determine the final outcome of the battery as compared with the initial value changed little.”

With regard to future plans for the automotive, Toyota is currently working with to reduce costs and to elaborate on the cars, while also considering a new generation of electric cars and personal mobility vehicle, used. Among them, electric vehicle batteries goal is to mass production around 2012. The corporation to consider a two-stage development of batteries, “First of all understand the limits of existing technology, and then to achieve the final form of the battery, in-depth field of scientific research beyond the limits of existing technology.”

Plasma TVs contain millions of microtubes filled with ionized gas that allows an electrical current to flow through, but physicists at the University of Illinois at Urbana-Champaign (UIUC) are developing what they call a “digital quantum battery” that uses billions of even smaller tubes (nanotubes).

By removing the ionized gas from the tiny tubes, the UIUC team, led by Associate Professor Alfred W. Hubler, wants to take advantage of the strong electrical fields to store electricity. When the gas is removed the vacuum inside the nanotubes acts as an insulator to store the electrical field. Professor Hubler says the device could store twice as much electricity as conventional batteries, and it could store digital information at the same time.

The battery is termed the digital quantum battery because it operates on the quantum scale, trapping the strong electrical field generated when negatively charge electrons encircle positively charged protons inside an atom. The device harnesses the most effective way to store energy, which is in the bonds between atoms. (The energy in gasoline and kerosene is held in the same way.)

The battery’s reverse-bias nanotubes are much stronger and smaller than plasma tubes and they contain little or no gas. Hubler said the tubes would be five nanometers long and billions of them would be packed together to provide enough power for most 15 V electronic devices.

Each nanotube could also represent a bit of information (0 or 1, depending on whether the tube is electrically charged or not). This means the device could be used to store digital information like a flash drive. Hubler said a flash drive uses the smallest amount of energy to store the charge, while the UIUC device would aim for the maximum possible amount of energy.

The state of the vacuum tube can be determined without discharging or charging it because a MOSFET (metal-oxide-semiconductor field-effect transistor) is inserted in the wall of the tube to detect the state inside the tube. Each tube has an energy gate and an information gate, which is a similar arrangement to the floating and control gates in a flash drive. The gates allow the nanotubes to be used to store information and energy.

Professor Hubler is the Director of the Center for Complex Systems Research at UIUC. The research paper will be published in the journal Complexity, for which Professor Hubler is an executive editor. The work was supported by a National Science Foundation Grant.
Digital quantum batteries

Great concept, awful name and physorg article.
The battery is termed the digital quantum battery because it operates on the quantum scale, trapping the strong electrical field generated when negatively charge electrons encircle positively charged protons inside an atom.

Dell’s Latitude E4300 is a 13.3in notebook for business users who are looking for something very portable, yet fast and well built. It’s a stylish notebook — ours came with a blue lid — and its straight lines make it look very clean. You get decent dell battery life and plenty of convenient features, such as a backlit keyboard, dual navigation devices and a built-in DVD burner.

It’s based on Intel’s 2.4GHz Core 2 Duo P9400 CPU, and it’s a very fast little notebook. It recorded a score of 104 in our WorldBench 6 benchmark suite, which is not far off the performance of a gaming notebook such as the ASUS G60J gaming notebook. You can use this notebook for creating elaborate office documents, image editing, and even chopping up and rendering videos. Our reivew unit came with 4GB of DDR3 SDRAM (you can get up to 8GB) and a fast 7200rpm, 160GB hard drive — the hard drive managed an average transfer speed of 30.72 megabytes per second in our tests. This is a little slower than notebooks such as Dell’s own slimline Vostro 13, but it’s still a very good result. There is an option for a solid-state drive, and you can even get the laptop with a second hard drive installed.

The only aspect of the Dell Latitude E4300 that’s weak is its integrated Intel GMA 4500MHD graphics adapter, which is slow and takes up some system RAM. It recorded 1020 marks in 3DMark06, which means it won’t be good for crunching 3D graphics, but it will be fine for running the 1280×800, 13.3in screen or a higher resolution monitor connected to the notebook’s VGA port. Another of the notebook’s weaknesses is its lack of a digital video port; you don’t get a built-in HDMI output or DisplayPort. If you want a digital video port, you have to purchase the one of the docking options.

Business users will like the speed of the Latitude E4300, but the build quality of the unit will also be appreciated. It’s made of magnesium alloy and it feels very sturdy. The lid flexes a long way without producing puddles on the screen, so it protects it very well, and the chassis can be picked up from either corner without any bending — even when you pick it up from the side with the optical drive. Metal hinges are used to keep the lid perfectly in place and the notebook is very well balanced; you can open the lid with one hand without the base lifting off the desk.

Around the sides of the E4300 you will find Gigabit Ethernet, USB 2.0, FireWire, headphone and microphone ports, a built-in DVD burner, an ExpressCard/34 slot, an SD card reader, a smart card slot, an eSATA port (sharing the same space as one of the USB ports) and a VGA port. For mobile broadband, you can purchase the Latitude E4300 with a Vodafone module, or you can use a 3G data card (ExpressCard/34) from your carrier of choice. There is a physical switch for the wireless networking module, which is an Intel WiFi Link 5300AGN module. The notebook also has a fingerprint reader, a webcam built in to the screen, and an ambient light sensor.

The ambient light sensor can adjust the brightness of the screen automatically. In well-lit conditions, the screen increased in brightness, while in dark conditions the screen dimmed. It wasn’t overly sensitive to minor changes in lighting conditions. Funnily enough, when we enabled the ‘Power Saving’ scheme, the ambient light sensor was automatically disabled and the screen brightness increased, but it did not do this every time. We found this frustrating.

To aid typing at night, the E4300’s keyboard is backlit and the keys illuminate when they are pressed. The lights don’t stay switched on permanently; even though there are settings for ‘on’ and ‘auto’, they seemed to behave identically. The keyboard itself is very tactile and feels sturdy when you hit it. There aren’t any misplaced keys, nor are there any abnormally small keys. We like the dedicated volume buttons above the keyboard and also love the fact that the E4300 has both a touchpad and a TrackPoint-like device. However, the latter does not feel as good as the TrackPoint that can be found on Lenovo laptops such as the X100e; the ‘eraser head’ that Dell has used is not tactile and the pointer is a little too sensitive. It takes a while to get used to it.

One thing you’ll notice when you first look at the Latitude E4300 is that it has two power buttons. The big one is the main power button, while the little rectangular one is used to boot into Dell Latitude ON.

Dell Latitude ON is a Linux-based operating system that resides in a dedicated module on the motherboard. Its role is to boot quickly into a low-power environment where you can send e-mails, check your calendar and browse the Web. What we really don’t like about Dell Latitude ON is that it’s very slow and doesn’t provide a rich browsing experience; it can’t cope with Flash and you can’t install browser plug-ins. It’s a decent enough environment for checking and sending e-mail via POP accounts, but that’s it. We think you’re better off just booting into Windows 7, where you will have a much richer user experience. The notebook can boot Windows quite quickly — it will only take around 40sec compared to under 10sec for Latitude ON.

Because the aim of Latitude ON is to boot up in only a few seconds when the notebook is powered off, it uses a standby mode that always consumes some of your battery power. It might not be much, but if you leave your notebook off for an extended period of time, you might find that the power capacity is reduced a little bit. In the BIOS, you can configure the laptop so that Latitude ON doesn’t consume any battery power when it’s powered off.

We were able to get more than four hours of use out of the 6-cell battery while using the laptop primarily for Web browsing and word processing. The battery life will depend on the type of work you do and the power settings you employ. For example, in our video rundown test — where we disable power management, enable the wireless radio, use full screen brightness and loop an Xvid-encoded video — the E4300 lasted 2hr 32min, which is a decent result for a notebook that doesn’t have a low-voltage CPU.

Because it’s not a low-voltage laptop, the CPU produces a fair amount of heat, and you will notice that the notebook gets warm if you use it on your lap for a while. It will be unpleasant unless you are working in a cold environment.

What we like most about the Dell Latitude E4300 are its speed and its build quality. It’s a very responsive laptop and it feels rock-solid when you handle it. Not only that, it has good docking options that make it easy to use the same machine at work and at home. We wish it had at least one more USB 2.0 port though, as well as a different style of TrackPoint; and we’re also not enthralled by Dell Latitude ON. But despite these things, the E4300 is a fantastic business notebook.

Telecom’s Twitter account is advising those still suffering problems after this morning’s outage to remove their batteries, then reinsert them to reset their phones.

However, as of 2.59pm, at least a dozen customers tell NBR they still have no service after following this advice.

Telecom blames network congestion as cell sites come back online, and advises people to “keep trying” .

EL PASO, Texas –Today find, A total of 7.3 pounds of cocaine were seized Saturday night after U.S. Customs and Border Protection officers found the drugs hidden in the battery of a pickup truck.

Officers found six cocaine-filled bundles hidden inside a battery case of a Ford F-250 pickup carrying a family of three, said CBP officials.

The driver of the vehicle, 49-year-old Juan Manuel Rodriguez of Lovington, New Mexico, was arrested by CBP officers. His wife and daughter were released.

During the weekend, CBP officers at the El Paso port of entry made nine additional drug busts, seizing 597 pounds of marijuana, said officers.

Last week, broker Michele Kleier drained her cell-phone battery four days in a row, fielding endless calls about one or another of her multi-million-dollar listings. The last time that happened, she says, was at the beginning of 2008, before the market went into its slide. “One exclusive where we just had our first open house, we had 45 people show up,” she says. Ditto Barbara Fox, who’s fielding dozens of calls on another apartment that has been sitting quietly unsold since last year. (In December, it took her just a week to sell a $2.4 million listing.) “Normally, our market’s quite sleepy in January, especially in the first two weeks,” reports Kirk Henckels of Stribling Private Brokerage, but this year, “[business] started right away.”

What’s driving this? Those bonuses that everyone’s yelling about—and the accompanying halo effect. “People are hearing about bonus money and thinking they’re going to miss out,” says Kleier, explaining that buyers who’ve been on the fence may be thinking prices have bottomed out. Activity’s not just in the sub-seven-figure range, either, as was the case this fall. According to Streeteasy.com, 122 Manhattan properties priced between $1.5 million and $5 million went into contract between December 15 and January 15, up 171 percent from the same period a year ago. “It’s surprising, given the current climate,” acknowledges Sofia Song, the site’s vice-president of research. “But with these bonuses, you get a larger pool of buyers for this price range.” The sweet spot? Between $2 million and $3 million, which accounts for more than a third of those contracts.

Warburg Realty’s president, Frederick Peters, suggests that it’s not actually bonus money at work—just that buyers are generally more confident, and that “they don’t want to miss buying close to the trough.” (Crain’s New York reports that many bonuses may come in stock, not cash, anyway, mitigating their real-estate might.) This is not to say sellers ought to start licking their chops, however. Henckels says past discounts have done what they’re supposed to do—stoke sales—but there’s not enough clamor to raise prices. “It’s the busiest I’ve been in a long time,” says Kleier. “Whether this translates into signed contracts, it’s too early to see.”

Port-au-Prince, Haiti (CNN) — Like many people who have done their time in Haiti, Gary Garner needs a good cry.

In the past five days, the Salt Lake City, Utah, physician has held a dying man in his arms and amputated more fingers and toes than he can remember. Now, he needs a rest.

Friday found him on the tarmac at the Port-au-Prince airport, searching for a way back to a normal life.

“We’re going to go home and cry,” Garner said in a low voice.

Then quietly, gently, with the suffering showing in his eyes as he looks away, he starts to cry. The pain can’t wait for home.

Elizabeth Bellino couldn’t wait either. The New Orleans, Louisiana, pediatrician sat in her car Friday and wept because doctors at another nation’s hospital would not accept a truckload of food and water from her. Nor would they let her pick up patients to take back to the University of Miami field hospital, where she’s been volunteering this week.

“It’s so frustrating,” Bellino said afterward. “Why would they do that?”
There’s much crying in Haiti. There’s certain to be more once caregivers and others get home.

For now, though, the work continues.

iReport: List of missing, found | Are you there?

Bellino had an increasing patient load at the hospital, located in a dusty field adjacent to the Aeroport International Toussaint L’Ouverture. A 5.9-magnitude aftershock Wednesday had given her new patients.

Even though Garner was trying to figure out how to get home, he still kept tending to patients being brought to a landing zone in three private helicopters.

Those helicopters belong to Utah businessman Jeremy Johnson, who offered to take a medical team to Haiti after last week’s 7.0-magnitude earthquake killed tens of thousands and injured thousands more.

Garner was a last-minute addition to a team put together by financial adviser Craig Nelson, a neighbor in Utah.

Nelson had been to Haiti on a Mormon mission 20 years ago, along with Steve Hansen and Chuck Peterson, now both Utah physicians. When Nelson heard about the earthquake, he decided they needed to go. Hansen and Peterson readily agreed.

They were dropped off Monday at the coastal city of Leogane, nearly 20 miles (30 kilometers) west of Port-au-Prince. The city was at the epicenter of last week’s earthquake, and some reports say up to 90 percent of Leogane’s buildings were damaged or destroyed.

The U.S. doctors were among the first caregivers to arrive and were later joined by teams from Cuba, Germany, Canada and other nations. Unlike what happened to Bellino in Port-au-Prince, everyone got along fine in Leogane.

“It was like the United Nations of medical work,” said Nelson.

“There were no nationalities,” Garner said.

They treated about 300 patients. The medicine was often rudimentary because of a lack of supplies.

One doctor used a Leatherman tool to amputate a man’s lower leg. Doctors also used a rack from the back of a bicycle as a makeshift orthopedic splint, screwing it into the patient’s leg bones.

The days were long, bleeding deep into the night. Sleep lasted three or four hours.

“We worked until our headlamps ran out of batteries and then people would bring us batteries,” Garner said.

“You can sleep when you’re dead,” he said. “And I’ll have plenty of time to sleep this weekend.”

And, no doubt, have a good cry or two.

Venture backed by private fund, public incentives

SAN FRANCISCO, Jan 21 (Reuters) - Lithium-ion battery maker Ener1’s (HEV.O) EnerDel unit said on Thursday that it would invest $237 million in a new factory to meet expected demand from automotive and smart grid sectors.

The company expects the new facility, near its Indianapolis headquarters, to more than double the unit’s manufacturing capacity. The factory will be backed by private funds and public incentives.

The new plant will give EnerDel the capacity to produce battery packs for about 600,000 hybrid electric vehicles, or 60,000 battery electric cars, the company said.

Lithium-ion batteries have long been used in consumer electronics products like cell phones and laptop computers.

Now, automakers from start-ups like Fisker to industry giants like General Motors Co [GM.UL] and Nissan Motor Co (7201.T) are readying electric vehicles powered by packs built up from hundreds of lithium-ion cells.

The race to supply those batteries, which can cost $10,000 or more, promises to create a booming market, one with no dominant and established vendor yet.

Industry estimates project annual sales of up to $25 billion in the next-generation auto batteries by 2015, up from almost none now.

Ener1 recently ended battery supply talks with Fisker, which awarded its contract to rival battery supplier A123 Systems (AONE.O).

Ener1 has partnerships with automakers Volvo (VOLVb.ST) of Sweden, Norway’s Think, and Japan’s Nissan and Mazda (7261.T), and is supplying batteries for a prototype hybrid version of the Humvee being tested by the U.S. Army.

On Thursday, Ener1 also showed off the new Volvo C30 electric vehicle platform, which is powered with its battery packs. (Reporting by Poornima Gupta; Editing by Lisa Von Ahn)

CONCORD, N.C. (AP) - A Charlotte-based maker of parts for lithium batteries plans to expand in North Carolina as it gears up production for the electric vehicle market.

Celgard LLC said Wednesday it plans to add about 80 jobs to the 390 workers at its Charlotte campus. The company also plans a plant in Concord that will employ about 210 people by 2015.

The company plans to invest about $90 million over the next five years.

Celgard’s North Carolina expansion plans have enjoyed a big boost from state and local taxpayers.

The company was selected last summer for $49 million in federal funds aimed at stimulating the next generation of electric-powered vehicles. The company could collect a state grant of up to $4.6 million if it creates the promised jobs and keeps them for 11 years.
