Japan’s solar cell market will shrink system

Recently, the market research firm Fuji energy-related economic system released the findings of the Japanese market. According to the survey results to predict the future, solar cell systems in Japan’s market will shrink. 2007 (April 2007 ~ March 2008), the Japanese solar cell system related to sales of 148.7 billion yen, while the year 2016 is expected to be reduced to 114.3 billion yen.

Because raw materials do not use silicon or silicon reduce the use of solar battery system is constantly expanding market, the system’s average price has declined, and the stagnation of domestic demand growth in the field of increasingly intense price competition, so Fuji economic forecast, the amount calculated by The solar cell market will shrink. The organic solar cell, estimated 2016 annual sales in Japan will reach about 2.4 times the annual 08 or 55 billion yen. This non-silicon solar cells are expected to increase, so the number of calculations predict the market will go according to Wang.

Hybrid lithium-ion rechargeable battery will pull the growth of the market

Fuji economic forecasts, after 2010, the Japanese lithium-ion rechargeable battery market, driven by demand for hybrid vehicles in the field, will be expanded. 2016 annual sales in Japan will reach 07 to about 2.9 times the 110.8 billion yen.

LED lighting in 2011 will exceed the frequency fluorescent lamps

Fuji economic forecast, the year 2015, lighting (fluorescent and LED lighting commercial frequency) Japan domestic sales will increase about 2.6 times of the year 07, about 41.9 billion yen. The formation of LED lighting market faster than initially forecast, major manufacturers are expanding investment in equipment. Fuji economic view, LED lighting market in Japan in 2011 will surpass frequency fluorescent lamps.

Japanese company GS Yuasa lead acid battery electric vehicles 90 years ago to reproduce

Hybrid and other environmentally friendly vehicles in today's high-profile, top-ranked Japanese company GS Yuasa lead-acid batteries will be about 90 years ago, the company has Taisho era of electric vehicles imported from the United States, "Detroit number" able to drive into the car repair, Shinan District 20 in Kyoto in Kyoto, the media headquarters on public display.

No. Detroit is the co-founder, the late Shimadzu source hidden in the back country in 1917, in 30 years or so, has been used as a company car, after they have been exhibited in Kyoto head office. As public concern on the increasing of electric vehicles, GS Yuasa Corporation started the car last year recovery plan. It is reported that, in the car equipped with the company's lead-acid batteries, the charger can be recharged using a household outlet.

No alternative to Detroit the same day using the bell horn, light and quiet debut. Driving the car company president Yi Tian Cheng said, "the feeling of riding a completely different with the normal car is indeed a power-driven carriage."

The implementation of the battery electric vehicle anti-theft number plate system

The implementation of the battery electric vehicle anti-theft number plate system

With the popularity of electric bicycles, in actual use, a very troublesome problem for consumers there - electric vehicles and electric vehicle batteries stolen frequently. According to the survey, many people have been lost in Yangzhou or battery electric vehicle experience. It is understood that the replacement of the current electric vehicle batteries, about 70% of consumers are victims of theft battery.

Recommended

Related to the implementation of military members suggested that electric vehicles number plate system. By the public security, industrial and commercial producers can carry an identity card similar reference electric bicycle license plate, license plates should be specified in the buyers name, invoice number, electric cars and steel to match the battery. The vehicle license plate provided in the sales of electric car, the corresponding increase city and out of the city crossing the mouth of the check card, such as providing no license plate, or vehicle with the battery does not correspond to the number of persons, vehicles and batteries to thorough investigation Department. Who do not receive before the car's license plate, with the original purchase invoice to the car at the replacement, so that stolen cars, the battery Xianchuyuanxing.

Increase investment in video surveillance devices by the use of public security monitoring checks at any time. Banks, shopping malls, hotels, business centers must force the installation of the door; hope still practiced in front of an effective system of security lump sum, restaurants, shopping mall security responsibilities should be clearly responsible for the inspection, should bear some loss of joint and several liability. Can increase the security of electric vehicle batteries propaganda, incentive intensity.

In addition, the proposed electric vehicle production and sales of the manufacturers and sales departments to improve electric cars and battery technology content of the safety locking device, anti-theft insurance factor to enhance the battery to prevent loss. At the same time, it is recommended to do electric car electric car manufacturing industry and the car battery corresponding relationship between the number of the form in order to find the owner as soon as possible after detection, and to the owner to become the most important witnesses alleged thief, so the thief to justice as soon as possible.

Applied Materials and Thin film solar cells

Applied Materials and Thin film solar cells

Two years ago, Applied Materials acquired Applied Films, successfully entered the solar cell and related equipment market, a year ago, Applied Materials introduced thin film solar cell module production line Sunfab, changed the size of thin film solar cell panels, and in October of this year, Signet Solar Applied Materials Sunfab using production line has achieved volume production. Applied Materials (China) Co., Ltd. General Manager Wang Ruiping solar business, said that in the field of photovoltaic solar energy, Applied Materials will continue to follow the established practice of the company, high goals, a large-scale forward.

Editor: Over the past two years, Applied Materials invested a lot in the PV business, covering the crystalline silicon thin-film batteries and battery equipment investment, can talk about the application of material in these two areas of current operating status, and future planning?

Dr. Wang Ruiping work at Applied Materials, a total of 14 years. 7 years ago she was in the United States, most recently in China for 7 years. Applied Materials in solar energy as a division general manager in China, she at Applied Materials China, Shanghai office as director of semiconductor technology jobs.

Wang Ruiping: In the film batteries, Applied Materials introduced in 1 year SunFab thin film solar cell module production line in the industry to establish a new standard size, will be the area of thin film solar glass substrate increases to 2.2 m X 2.6 m mainly to lower production costs and installation costs. Through our efforts, there is already a client and we have signed the final acceptance certificate, which for the Turn-key production line equipment supplier is not easy to do. As for the future planning, in order to increase productivity and reduce costs, we will continue to strive to make Sunfab more efficient production lines, 1 U.S. dollar per watt below target. In crystalline silicon, we have also acquired several competitive companies to increase our product range, especially in relatively high-tech products. Application materials have been acquired over the past few years, HCT, Applied Films and Baccini companies in the sales of these products, we consider how to increase product differentiation, to distinguish it from other suppliers in the crystalline silicon industry to do it their own achievements, commitment to the whole factory automation and high conversion efficiency. Continue along the established practice of Applied Materials: high goals, a large-scale forward.

Edit: In order to improve industrial competitiveness, reducing battery module manufacturing cost is very important, do you think of the product cost reductions will be mainly reflected in what areas?

Wang Ruiping: lower costs, a bit like the "chicken and egg" relationship, there is no application would not promote the development of new technologies, no new technology there is no way to reduce costs and expand more applications. Many cases, is not high and the low cost, but there with no problems. In the peak, the solar power grid does have a very small difference between the phases. From this perspective, the cost of solar power is not very far away from the traditional use of electricity. In the past 30 years, reduce the cost of semiconductor 2,000 times in the past 10 years in reducing the cost of flat panel display 20 times, and reduced by 5 times as long as the solar PV, with the current thermal power, hydroelectric power, compared absolute cost competitive advantage. Although in most cases the cost of solar power quite far away from grid parity, but as a supplement peak power now exists, does not need to lower prices. China's large population, energy demand is big country, if not soon, then stimulate domestic demand clean energy, it is difficult to solve China's energy and environmental issues. Now there are two relatively small photovoltaic projects supported by the State, but I think the support is not enough. We hope to see a more active policy to support small-scale solar power generation application development to the GW-level large-scale power plants. PV scale itself is a need for continuous learning and improvement process, the state should support the PV industry in the whole industry chain has chosen to focus on support.

Editor: How to deal with small and medium enterprises to re-shuffle in 2009?

Wang Ruiping: I think the small and medium enterprises to enter the industry will become increasingly difficult because the industry is in rapid development to larger scale stage, large-scale industry will be realized in the near future. SMEs need to survive according to their own advantage to avoid weaknesses. Economic recession and the downturn in the next year not only for the solar photovoltaic business, for all the world's enterprises are particularly challenging year. PV industry in China is too dependent on external demand, the financial crisis on the domestic impact of large solar energy companies. The emergence of the economic crisis companies with limited cash flow is a huge challenge, good cash flow for the company, but it is a good opportunity for development. Important that the strategy of each company, with limited funds to do the most important thing. I think no matter what the economic situation is, as long as to effectively stimulate the market demand there will be way out.

Editor: PV equipment industry made in the past few years has been some development, your Chinese domestic equipment suggestions on how internationalization?

Wang Ruiping: I think the country is still very competitive these companies, the technical content, quality, although still to be improved, but the relatively low cost price, in China's environment, which is the largest competitive. This is the place to learn of large international companies, Applied Materials will combine the technological advantages of our cost advantage of China quickly into the idea of being product development. In a competitive process, whether international or domestic business enterprises are facing the same challenges, but points from different angles. I think this is each other, mutual learning process, who learn quickly, one who will do better.

Silently into the fast lane

Silently into the fast lane

While honing his Porsche Cayenne hybrid is already a Tesla competitor in 911-base work. The E-Ruf is not yet ready for production, weighs nearly two tons - and runs at least 225 cases.



What makes a real 911? The rear-wheel drive of course. And the six-cylinder boxer engine with its powerful babbling and the fantastic ride. At least six of you have to adopt in the future, well, if the E-Ruf A model is developed for mass production. Based on a Porsche 911, the tuner and car manufacturer presents call from Pfaffhausen an electric sports car, and shows how in Zuffenhausen might look like in the future.

The three-phase AC motor measures only 40.5 inches in diameter and sits in the engine compartment just behind the rear axle differential. Also, the electric 911 can therefore claim to being a real Hecktriebler. The engine delivers a maximum of 150 kilowatts (204 hp), torque of 650 Nm is available immediately after the launch. The Tesla Roadster would drive behind the Porsche at the moment anyway: The E-Ruf is to speed in about seven seconds from 0 to 100 km / h, the development objective is somewhat spongy "under seven seconds." The Tesla creates the sprint to 100 km / h in just under four seconds, but weighs 1.2 tonnes and well below the 1.9 tons of heavy e-reputation. A normal 911 takes about 1.5 tons on the scale - and him in a maximum of five seconds to 100 km /

The lion's share of the additional weight of course make the batteries from the E-Ruf 550 pounds drags it around with him. Engine and the front luggage compartment are completely besieged by batteries. The engine itself weighs only 91 kilograms. The maximum speed of the electric Porsche is located at 225 Km / h. "For the further development steps are still modifying" to expect befitting features, promises the car manufacturers. The electric Porsche has a gearbox with six gears. "In fact, it is probably enough to insert the sixth gear and drive off with the gas pedal," tells reputation and adds that it is in an electric car really more of a handle, "Ampère pedal."

An improvement in acceleration was possible if you choose one of the lower gears. "Of course one is so strong sprint capacity at the expense of the achievable range," restricts the automaker. The 96-Lithium ion batteries put together an energy reserve of 51 kWh available. "This represents the theoretical pure energy content of 5 liters of petrol and indicates the difficulty of storing" electricity, say the reputation of developers. The performance of spiral in the battery development interpret but sharply upward. When coasting, the motor generator and produces electrical energy with which the batteries are powered.

The stromernde 911, unlike the Tesla Roadster an experimental vehicle. "The prototype of the A-series is" still a significant distance from the fully developed car with electric drive, says the company reputation in a statement. The range of the E-Ruf model A lies at 250 to 320 kilometers. The life of the battery is charging cycles to the reputation of 3000 would be almost four times as much as the Tesla Roadster. During operation, the electronic monitors constantly the voltage and temperature in the battery cells in order to avoid overheating.

The idea for the electric Porsche is the company president Alois Ruf Jr.. been associated with its three hydropower plants, says the company. "The annual amount of energy from these power plants is about 35 million kWh of energy that would be necessary to a car like the E-Ruf 3500 times" to let go of the globe, the company estimates. "The whole thing is in the public network by the treaties of the energy for day or night current equivalent of € 2.50 to 5 per 100 kilometers," reads the statement of the automaker. lenovo thinkpad x41 battery

The company, established reputation in the Bavarian Pfaffhausen employs 65 staff. Reputation is not only Porsche tuner, but registered since 1982 as a vehicle manufacturer. The first model with its own telephone chassis number was the call of BTR with a 374-hp turbocharged engine.

French understatement B

The trunk has shrunk compared to the previous light, with 467 liters capacity, but remains high. The E-Class Mercedes for example, is content with 400 liters. The back seat for the C5 is also divided asymmetrically and can be folded down without much effort - this creates extra storage space when needed. The tailgate itself can be opened easily and far and also the opening is large enough dimensions. vgp-bpl8 battery

Angry however, the high sill, over which one must haul his bags or shopping only once. The felt fabric with which the boot is designed can be further bad clean. And here are a few small shelves would have been helpful. Under the boot floor hidden way to request a full spare tire.

The clarity from the driving position is not the best - making the body section of the C5. It looks good, what happened before one goes on the road, when parking but more by feel than by certainty. Beginning and end of the car can be guessed, the wide B-pillar also interfere. The electronic parking aid (€ 700 per packet) is therefore useful invested capital.

The four-cylinder diesel under the bonnet enough with its 100 kW/136 hp and a torque of 320 (in the boost mode, it briefly 340 Nm) is sufficient for the 1.7-ton truck quickly and swiftly through the traffic to . move The booster makes for brisk overtaking on country roads, overtaking on the highway at high speeds is not quite as crisp. The sprint from 0 to 100 km / h creates the C5 diesel with manual transmission in acceptable 10.6 seconds at 204 km / h is the maximum speed reached.

Over the whole range of motor runs quiet and cultured, the noise in the interior remains pleasantly quiet. When the C5 consumption shows more on average: Official 6.0 liters of diesel per 100 km are in the same order as in the test measured a good seven liters. The particulate filter is standard.

A highlight for the C5 is expected, the ride comfort. The hydropneumatic suspension muted hovers over all the bumps and keeps them away from the passengers. Only if the transverse joints or potholes are too violent, even more will not help the hydro-pneumatic. Adaptive Suspension controls depending on speed and road conditions also, the ground clearance of C5.

The chassis can move on tracks such as the Citroën its path, directional stability, even in critical situations kurvensicher and well controlled. The steering is precise, but gives little sense of the road. The 6-speed manual transmission flutscht without heel and on short routes through the scenery, the course itself are well adapted to the engine. All this makes for a relaxed feel.

For a base price of € 27 350 of the C5 with a 2.0-liter HDi Although no marked bargain, but in view of the extensive standard equipment a very fair deal. Are recommended from the options list, the Bi-Xenon Headlights (930 €) and the lane departure warning system that signals an overrun of the road marking without flashing gently awakening shock in the lower back (610 €). lenovo thinkpad t500 battery

Those who travel a lot, is expected to make friends with the 6-speed automatic (1500 €), which switches smoothly and precisely, making the cruise more enjoyable with the C5. The Citroën C5 is still one and thus a Frenchman. And that's good.

With the updated C5 to the French in Germany finally break into the business with a company car. The comparison does not shy away from the local middle class, the import from the neighboring country. vgp-bps2a battery



Where only the French healthy self-esteem is gone? Your C5, praise the recruiters of Citroen, was "as good as a German car, the middle class." And got to see in the TV spots, the British TV audience for a while, an Aryan-looking Blondling C5 slides over the dark streets, which suggest, if only for the black letter of the Ortswegweisern a fairly clear geographical and temporal mapping. vgp-bpl9 battery

Quite superfluous all this: who is with the C5, which has the first kilometers absolutely no doubt that the comfortable touring car is comparable to any German agents in their class. Citroen calculated to be able to advance thanks to this self-denial, finally succeed in the fleet of German managers floors. There traditionally dominated especially the Teutonic Trinity Mercedes, Audi and BMW.

Only by using the company car fleets are, however, by the calculus of the French still get the sales, which collapsed on the private market for a long time are no longer possible. But what stands in the way while the C5, the less likely to be his equal because of the technical qualities in these circles more conservative tastes. Individualists will love the Citroën design. On compliance and visibility drilled manager probably less serious.

You do not know what they are missing. Because of a C5-round balanced, high quality and very comfortable car has become, made with a lot of intelligent technology and quality. Sometimes a bit too much. Who in the comfortable driver's seat position is occupied, will feel immediately at home though - but at least when looking at the dashboard and steering wheel to the first sample set. Plenty of display instruments, it is because in the function and position to internalize. vgp-bps2 battery

And on the fixed steering wheel hub for Citroën kind he will find his way when driving under 20 switches. That can only look with - what shall prevent the switch in Daumenweite yes usually straight. Moreover, those things are so small that most still need to aim very carefully. And whether, in the split second of the two also need a lot of hits on small buttons of the horn may also be questioned.

Otherwise: The interior of the C5 is the best French cinema. With a balanced design, a pleasant blend of angular and curved elements plus high-quality materials that feel consistently good. The workmanship is very neat - even where the eye falls normally not the same. If you are used only once in the scheme of the abundance of these switches and knobs, the C5 can also be quite easy to use - much of it takes one from the electronics.

Thus, the parking brake when parking as when riding works automatically, daytime running lights as standard, the headlights are switched at the request of sensors and the steering wheel can be adjusted very individual. There is ample space for passengers. Front will also have people with more than 1.86 cm in height no problems. Pleasant abundant (more so in comparison to the German middle class) is also the great width, which ensures that the passenger is not kept clear. The seats are very comfortable and offer good lateral support. Even long journeys can be complete so without fatigue and dislocation of long legs. lenovo thinkpad t400s battery

Rear, the space just as comfortable for two adults - a third space is limited. The knee space is plentiful, the space above their heads is because of the sloping roof line for tall but somewhat narrow. What the front and rear painfully lacking is enough and sufficiently large bins.

Feedback dents or the muscle of the screen

Feedback dents or the muscle of the screen

Touch screens in devices are smart, intuitive, and since the iPhone socially acceptable than ever. But for ease and speed of the keyboard, they are lagging behind. An American company wants to change that – in the muscles with thin display.

"Haptic feedback" it is, if a device provides the user with a tactile feedback to a command – for example, touch-sensitive screens. Sun vibrate some mobile phones from Motorola (Motorokr E8) and Samsung (Omnia) for each finger tapping on the display. Each computer player knows its own activities or devices to communicate through vibration and jerky more realism and control.

But a short vibrate with touch on smooth surfaces alone does not facilitate the orientation on-screen keyboard – and certainly not blind. For a more realistic impression the company wants to Artificial Muscle with artificial muscles provide under the display, which it unveiled at the CES electronics show in Las Vegas. Smart Touch called the whole thing.

The artificial muscles are made of a special electronic deformable plastic that is placed below the screen, for example, a mobile phone. This allows the display film can be increased so as to create a sense that a bump. Which will then provide a most realistic impression of a depressed or let loose button.

According to the magazine, the Golem induced deformation also walk across the screen and be moved. Thus, other applications are possible – not only in mobile. In a decision but the equipment manufacturers and their programmers themselves determine, for Artificial Muscle provides only the technology, not the devices.

A very pragmatic purpose, anyone can imagine who has ever struggled with touch-sensitive screens of ATM machines or ticket: a sensitive operation with clear feedback would press the tiresome, Wipe and pick on superfluous.

Japan in the worst crisis of the postwar period

Japan in the worst crisis of the postwar period

The Japanese economy has shrunk in the face of unprecedented exports slump as much as since the oil crisis is over 35 years ago. Like Germany, the Land of the rising sun is dropping on the exports.

As the Japanese government today announced a provisional basis, the economic performance from October to December fell expected for the year by 12.7 percent. "This is the worst economic crisis of the postwar period is", said the Japanese Minister for Economic and Fiscal Policy, Kaoru Yosano.

The previous month, gross domestic product shrank BruttoinlandsproduktDas the total value of all goods (goods and services included), which are produced within a year. (GDP) of the highly export-dependent motor, the second largest economy in the world by 3.3 percent, while in the third quarter in a row now. Thus Japan slid deeper into recession than the U.S. and Europe. The exports dropped by 13.9 percent, as strong as ever. Given the global economic crisis, demand for Japanese cars and electronics products has declined dramatically.

In addition, the rapid rise of the yen. The shrunken external demand pushed Japan's GDP by as much as three percentage points and thus as strong as ever. The decline in domestic demand also lowered the GDP by a further 0.3 percentage points. Against this background, expect companies like Toyota, Sony and Hitachi in March until the end of the current fiscal year by the bank significant losses and eliminate tens of thousands of posts. This is reflected significantly on the mood of consumers, which threatens to prolong the recession.

Consumer spending, which account for 55 percent of the country's economic performance fell in the final quarter of 2008 in real terms 0.4 percent from the previous quarter. The capital expenditure of the company fell by 5.3 percent. In relation to the preceding calendar year, the economic performance fell for the first time in nine years in real terms by 0.7 percent. For the end of March until the current fiscal year 2008/2009, the government expects a drop in GDP of 0.8 percent.

That would certainly be achieved only if the economy zulage in the current quarter by 5.6 percent. The last many economists, however, is unlikely, but they expect a further contraction. Japan's Prime Minister Taro Aso wants true that Japan is ahead of all other countries from the crisis. However, economists are of the opposite: Only when the U.S. and Chinese economies recover, it will also back Japan to go better. Because Japan is much further from the export, not domestic enough.

Meanwhile, Yosano Minister pointed out the need for swift adoption of the second supplementary budget of the government. The Parliament, where the opposition in the House of Lords has blocked the majority of votes, but the adoption of a powerful Wirtschaftsankurbelungspakets of which is under increasing pressure Government Aso. His poll ratings have fallen deep in the cellar. There is already speculation that Aso may be replaced before the latest in the September elections to the House from his Liberal Democratic Party. The past 50 years almost continuously threatening the ruling party losing power.

Spring fever in the BMW Z4

Spring fever in the BMW Z4

In the roadster segment, the Z4 always drove behind the successful SLK. That should change now: with more comfort and practicality as well as a magnificent chassis of the new Z4 is a star fighter.

"A Roadster is pure emotion. Something works well in difficult times, "believes Klaus Borgmann. The new BMW Z4 wanted to "take the existing customers and" new to win, says the head of the 1 Series, 3 Series, X3 and Z4-series. In view of the Bavarians have mainly with customer comfort.

The Z4 is now less purist and hard than before, but more comfortable and suitable for everyday use. If the adjustment of the steering wheel fully exploited, tall passengers will find their ideal position Volant hinterm. Thanks to electronic parking brake remains room for a center console with small storage compartment and cup holders. Behind the seats can be stowed in a few little things luggage racks.

The wide hatch in the trunk makes it possible to carry two pairs of skis or other bulky luggage. The boot holds 310 liters with the roof closed (In comparison, Mercedes SLK 300 Liter, VW Eos: 380 Liter, Audi TT Roadster: 250 liters).

If one wants to go open space is left for 180 liters of luggage which we stowed under a plastic cover. Under the boot floor you will find the way, the battery – it makes it better for yourself comfortable weight in the rear.

The electro-hydraulic hardtop roof consists of two aluminum trays. The complete system weighs about 90 kilograms, 30 kilograms more than the old Z4 with soft top. The hardtop is operated with switches in the cockpit or car keys. The folding process takes 20 seconds and only works in standard.

Body developers Gerhard Schmid Mayer points during the journey must always be visible on the legislation: "The third brake light." Since the folding process of the Z4 swings the door up, that would not be guaranteed.

The reasoning may be understandable, but it remains impractical always to have to go in order to worship the sun always just the right quickly. For in the Z4 one likes to be open whenever it comes: the air turbulence at the top down hold is very limited.

All models are equipped with straight-six petrol engines. So far, one could only test the most powerful engine Z4 sDrive35i in connection with the seven-speed dual-clutch gearbox. The turbocharged direct injection with double takes from three-liter 306 hp and develops a maximum torque of 400 Newton meters.

The result is an uninterrupted flow of force – as long as the speed does not far fall below 1500, is actually more from the post. The dual-clutch transmission shifts so smooth and responsive that the 5.1-second acceleration from 0 to 100 km / h almost seems a little unspectacular.

In the soundscape for the Z4 is in the solid: the usual run of the silky six-cylinder is accompanied by powerful noises. The fun-surcharge you pay at the pump. 9 liters per 100 kilometers, the official average fuel consumption, with jagged mountainous driving on a highway on-board computer showed about five gallons of more. When it is more relaxed approach, after all, is the 9 in there at least before the decimal point.

All BMW Z4 Control Fahrdynamic have on board, with the push of a button you can change the character of the car. "From the normal mode of" Sport "to" Sport Plus is the responsiveness of the accelerator pedal and the spontaneous switching processes are shorter.

The steering is noticeably more direct. In Sport Plus mode, the electronics can be also easy to slip on the drive wheels. If the driver is sure of his cause, he can also turn off the ESP.

The Z4 drives are not quite as crisp as Porsche's mid-engined Boxster roadster, and is particularly adapted a touch more comfortable. In fast corners, the BMW still feel completely in his element. He is very calm during sudden load changes on the road, unpleasant surprises, such as lateral displacement of stay. Even during heavy acceleration and delays, there is no pitch or roll movements.

The BMW Open is an expensive pleasure: 35.900 € costs the Z4-based model sDrive23i (204 hp). The old base-Z4, was even with much weaker and thinner engine equipment, or for just under 30,000 € have.

The competition reaches also to sound. The Audi TT Roadster 2.0 TFSI (200 hp) is to be had from € 34 150, the Mercedes SLK Kompressor (183 hp) from € 37 217 and the Porsche Boxster (255 hp) from only € 46 142.

The basic equipment of the Z4 include the Fahrdynamic Control, Xenon headlights with washer, air conditioning, CD radio, multifunction steering wheel, and daytime running lights. From sDrive30i (258 hp, € 42 900), leather upholstery is on board. The top model sDrive35i (306 PS) costs € 47 450.

Shrill, stylish and simply different: the Kia Soul mixes the dreary monotony on German roads inspiron 1420 battery, including hard on - flashing speaker. But sometimes you get yourself in the Soul of the Blues.

"If the four-wheel drive?" The question one hears often with a Kia Soul at the gas station. The angular cross between a van and SUV looks a little adventure - but this is limited to the city: The Soul is a normal front-wheel drive without any off-road ambitions. The pleasant side effect of the edge-looks is a good clarity when parking.

The high seating position provides data transport turmoil. Only at the point of view diagonally to the back interferes with the thick D-pillar a bit. The overhangs are very short of the Soul (vehicle length 4.1 meters by 2.5 meters wheelbase) and the turning circle gd761 battery is relatively small, so the car can be easy to park.

The cockpit of the Kia is in comparison to the body rather conventional, but this is not a disadvantage. The conservatively-designed fittings are perfectly readable and the controls well placed. Apart from a few colorful accents awaits the passengers much hard plastic. Most impressive is the range of bins. At the center console sits a USB port, and next to the cigarette lighter, there are an additional twelve-volt connection.

You can tell that the Soul is designed for people who like to let off steam with cell phone, iPod and other electronics. This is also reflected in the "Mood" lighting, which can be activated in the Soul of a button. The boxes in the foot then reddish glow or blink to the beat of the music. However, you take the pulsating lights while driving true only in passing.

Such gimmicks can not hide even the fact that the soul actually has to offer rather little. Although space is very neat front and rear. Especially in the rear there is a van-like sense of space. But a variable bench as the Honda Jazz is absent altogether, there's only td347 battery fold-down seat backs.

After all, the boot capacity increases with seats folded down to a maximum of 1140 liters, for in the normal state it is not very abundant. Honda Jazz or Citroen C3 Picasso have to offer much more. When subdivided into compartments compartment under the cargo cover is not on board, the capacity of the soul grows to 340 liters.

Kia offers two drives for the Soul: A diesel engine with 128 hp (switch or automatic) and a 1.6-liter four-cylinder petrol engine with 126 hp and manual five-speed gearbox. With 1.3 tons of the Kia is not exactly a heavyweight, and if you change the gears too early, it is quite fast on the road with the petrol engine.

The acceleration from 0 to 100 km / h is fine. The average consumption is 6.6 liters with Chia per 100 kilometers, which our test car could not meet, however. One was 8 actually always in front of the decimal point, and on the highway, the Soul proved themselves in leisurely kd476 battery 120-150 km / h as pretty thirsty.

More fun to the chassis of the Koreans. It is more tightly coordinated and scars with short bumps just past the border to the inconvenient, but the road situation will benefit the vote. The Soul can be swiftly and accurately measure exactly at the corners. Prices start at € 14 980, are on board then with ESP, CD radio and electric windows. Extras such as air conditioning, fog lamps and control keys on the steering wheel until you get higher quality equipment. Different color or interior styling packages are only for the top version of Spirit (have from 18 950 €). For 1440 there is an extra € sunroof, plus additional speakers amplifier and a rearview camera with display in the rearview mirror.

It is hard to find cars that are directly comparable with the Soul. The design is just too specific. Classical high-roof wagons such as the Renault Kangoo or the VW Caddy is larger. A few inches shorter is the Fiat Qubo (329 liter trunk, with 73 hp petrol engine from € 12 990, the diesel version is good from 14 590 €). A similar concept of space as the Soul of the 4.2 m long has Skoda Roomster (450 liters of luggage, with 105 hp from 17 330 €).

The Opel Meriva about playing in the place of soul-Liga (360 liter trunk, starting with 105 hp 18 890 €), lenovo thinkpad t400s battery as is the Nissan Note (280 liter luggage compartment, sliding rear seat, with 110 hp from 17 890 €), the Honda Jazz (428 liter trunk, with 100 hp from 16 290 €) and the Citroen C3 Picasso (385 liter trunk, with 120 horsepower from 18,000 euros).

Wet road: A dirty affair

Wet road: A dirty affair

ABS, ESP, ASR: Electronic braking and lane departure warning systems are now standard. On wet roads but the car still reacts differently to drought presario 2500 battery. Here is: Who will keep its cool and knows his vehicle is clearly an advantage.

Rain can make even the most experienced drivers of problems. The rain mixes with dirt and oil on the roadway, creating slippery road conditions. In order not to come loose of it is, therefore, to lift the accelerator. "At lower speeds, the tread of the tire more contact with the road, which leads to better traction," said Carsten Bitzhenner by the tire manufacturer Goodyear in Cologne, the first concern for a safe journey.

But even the most cautious driver can get his car into a skid. When this happens, the brake is off limits. Is an anti-spin system on board, the electronics can remedy the situation even if the frontiers of physics have not been exceeded, so even so-called residual liability ideapad u450p battery. Countersteering should be sensitive and requires very little practice. In most cases you can indeed correct the first centrifugal movement yet, but it is often the opposite lock override - so much drawn to - and the desired stabilizing effect of trams to the contrary.

Rear, front-and four-wheel drive

In general, car drivers aware that their drive concept car has. Front, rear and four wheel drive are the most common species. Are all wheels driven, the car on wet roads is the safest way. Is it risky driving situations can provoke almost entirely aware of. Front-wheel drive in most cars of today are built on and runs good-natured in wet or snowy roads. The limit range of front-wheel drive is great, and the approach to the liability limit is announced. The car understeer and push the front wheels in the direction of track you. This means also: device once the vehicle out of control on bends, it is difficult to capture. Most of the car then just pushes straight ahead - no matter what the driver wants to take it.

It is different with companions, which means that only the rear axle is driven by the engine. The disadvantage: If you game on the gas occurs or brash moves in a curve that breaks the fast from the driven rear axle. The vehicle is overloaded. The advantage: With a little practice can capture the Heckler then again - by gentle counter-steering and constant pressure on the gas. Difficult, however, is moving off on snow-covered mountain. Overall, requires a rear-wheel drive driving feeling something, the so-called Popometer and exercise promises, the experienced pilots but more fun to drive. Tip: Without risk, you can train those driving on a snowy driving range evo n610c battery.

No busy steering

Basically, the driving in wet conditions the cautious handling of steering, clutch, brake and accelerator pedals, and a greater potential for errors and emergencies. tripled on wet roads, the braking distance to dry roads. Therefore, it is important aufzufahren not too close and well over half the speedometer reading in meters distance to keep.

The brake should be used only highly dosed. Even more: "Avoid heavily on the brake. If possible, back the speed by "going off the accelerator, advises Bitzhenner. True, it is also to remain calm and not to produce steering movements hectic. It makes sense to open in full brake pedal several times and then press again. Thus, the price of the car will be corrected in the delay intervals. In most modern cars, which is now regulated by brake assist, such as the ABS. They have the effect that the car remains steerable.

What to do when hydroplaning?

To hydroplaning occurs when the front tire accumulates more water than can be displaced by the vehicle weight. Because the water pressure, the vehicle is lifted and floats on a thin layer of water between the tire and road. Here, the vehicle can lose contact with the road completely, and there is a danger that you slip out of the lane or even off the road. So is "foot off the gas, the commandment" in such ticklish situations. Should also be avoided ruts and ideapad y430 battery depressions.

"When it comes to aquaplaning but may not steer you brake suddenly or," warns Bitzhenner. "This would enable the car to skid. should go gently off the accelerator until the vehicle slows down and you feel that re-liability. "To avoid aquaplaning we also ensure that the tires always have the correct air pressure and adequate tread depth.

The European Commission (EC) has commissioned the chip designer ARM, with the guidance of a project in which it comes to energy-efficient data centers. "Cloud €" aims to develop a very low-power server for Nokia's Ovi service cloud maps, supplies the mobile device with maps for navigation.

ARM is working with Nokia, the specialist in nanotechnology IMEC, Ecole Polytechnique Federale de Lausanne and the University of Cyprus. Euro Cloud has already received an undisclosed grant from the European Commission, should be enough for three years.

The project is based on low-power ARM Cortex-A9 multicore processors and dell vostro 1510 battery 3D-DRAM memory modules. These techniques should reduce the energy consumption.

The € Cloud project members assume that servers are available with the design already developed by them in 2015 in the data center. The aim of the project is to accommodate hundreds of processor cores in a single server. "We must achieve energy-efficient multi-core processors for a breakthrough," said Panagiotis Tsarchopoulos, who is in charge of the European Commission for the project. "Brings € Cloud is an interesting research project, leading European low-power technology in the field of embedded computing in general computer technology."

ARM stated that the company had so far focused on energy savings in mobile devices. Now would you turn to the power consumption in data centers. "The performance and the new features of our recent processor models have reached a level where it makes sense to explore how ARM technology, the major challenges in energy consumption of wired applications - solve, for example in data centers -" said Krisztian Flautner, Vice President of Research at ARM.

Project participants will present their concepts for a low-power server on the € Cloud Cloud homepage. It says: "Cloud computing applications require greater parallelism to thread-level or memory. A parallelization at the level of individual instructions is little. Each client request is answered by a single or vgp-bps9 s battery multiple independent threads, all on a separate processor to run. "

The timing of the introduction of the new Apple laptops is still unclear. While Audioslave716 calls as the deadline next Tuesday, told other sources to MacRumours, such a short-term market launch is unlikely. Because numbers have been determined, it seems likely that the Macbooks will appear sooner rather than sony np-bg1 battery later.

In another sign of an imminent change of model is that certain variants of the 15.4-inch MacBooks Pro with the U.S. retail chain Best Buy is sold out. This applies both to individual stores as well as the online shop of the company. In contrast, all of Apple Macbooks Pro are available within 24 hours.

Already in February, rumors had surfaced first on a Macbook Pro with Core i7 CPU. Benchmarks showed a Macbook Pro 6.1 point, one not previously used model name. The fact allegedly obstructed Core i7-M620 is the fastest of Intel in January introduced 32-nanometer processors for notebooks.

In the process of MIT, tiny molecular chains depend independently on a silicon chip out (Image: MIT).

Researchers at the U.S. Massachusetts Institute of Technology (MIT) are working on a new method by which the production would be cheaper of highly integrated circuits. These molecules are used to organize themselves independently in the chip manufacturing useful nanostructures. This allows relatively inexpensive accommodate smaller circuit elements on a chip.

The procedure is presented in the current issue the journal Nature Nanotechnology. it reaches the market, it could be an alternative to photolithography, which is now used for chip production.

As the MIT Office, is the problem of photolithography, the switching elements are already much smaller today than the wavelength of light used in lithography. For very small structures could be used to replace the electron beam lithography, but this technique is very time consuming and expensive. It is thus sought a method by which you can make the tiny structures efficiently.

The team of scientists led by Caroline Ross and Karl Berggren, the electron beam lithography and share only one to place a "post" at the nanoscale on a silicon chip. Then they carry on so-called binary copolymers. They are large molecules that consist of a chain of two different molecules regularly arranged units.

These copolymers spontaneously attach themselves to the previously set "post" and align themselves in a particular formation, as they want as far away from each other. Berggren explains the behavior of molecules based on the movie "Midnight Run" In him a bounty hunter and a criminal is bound together with handcuffs, but can not stand for death.

By changing shape and arrangement of the "post", the proportions of the polymer and the length of the molecule chains, you can create different structures. Including those such as are used in chip manufacturing.

If the resulting plasma structure, suspends, burning away a molecular entity that is different to glass. This achieves the same effect as one of resist in electron beam lithography. This changes the resistance of the coating when it is irradiated with light.

If you send light through a mask onto a photoresist layer, so that we can create structures. This works similar like a photo negative.

In contrast to the photoresist can be created with the copolymers but much finer structures. can be used industrially until the procedure is, however, still take time. The team of Ross and Berggren is currently working to produce a prototype of a fully functional chips.

But fuel cells also have their own problems. Now, a direct ethanol fuel cell to add is not mature enough, while the methanol toxic and volatile than the alcohol faster, of course, higher energy density than ethanol. These elements add fuel to the fuel cell is an issue, and the fuel storage is not a small challenge, this toxic stuff on the street Are we going to sell Mode? Is obviously impossible. And on the plane how to do? Perhaps the future of the airport toilets should assume their task of another one – methanol before boarding the collection, this way, the fuel cell will not be too convenient to use them.

Moreover, fuel cells, lithium batteries can not be as great as the energy of tolerance, the power output of a more balanced and therefore unable to cope with the unexpected peak power demands, coupled with its ups and downs of power can not be too strong, affecting the fuel cell applications.

Fuel cells also have to face the operating temperature. Hydrogen fuel cells can be as low as five degrees Celsius under the conditions of work, the scope of work I am afraid that the temperature of alcohol should be higher. This is the average person may not be a big problem. However, hydrogen fuel cells will require a sustained pressure of the air flow through the battery module, which will lead to noise and general users make it difficult to accept, as if the face is not the same as electronic equipment but the machinery and equipment.

Recent studies have made a noise reduction efforts, it has greatly reduced operating noise. But we also need to pay attention to start the hydrogen fuel cell energy is needed, that can not be completely abandon the traditional batteries, fuel cells can not allow access to each mobile device, but can only become the center of personal power.

However, this is not the issue of alcohol fuel cells, their responses can be reduced to the middle of the reaction with water, thus surrounding the electrode, water and methanol concentration requires careful consideration and can not be too thick or too thin. We still look forward to practical use of alcohol fuel cells, and only at that time, the battery can also be, like people, drink …I am afraid that time would have the popularity of fuel cells.

Products are all exported to Japan and South Korea, respectively, exported 192.9 thousand tons and 1.18 million tons. Foreign-invested enterprises to export the main force, a total export of natural graphite 158.7 thousand tons, accounting for 77.5% of total exports.

As the iron and steel, automobile and other industries, domestic and foreign markets to increase demand for natural graphite. At the same time, our country decided to September 1, 2006, the right type of graphite related products, the implementation of the interim export control measures can be used as alternatives to stimulate the natural graphite export growth. Experts pointed out that because the blind exploitation of China in recent years led to excess capacity of graphite, export market disorder, the export of natural graphite showed a fall in price trend of increase in volume, should pay attention.

Hydration and temperature

This article via: Hydration and temperature

In this paper the researchers set out to create simulations that examined the impact of hydration and temperature on the positively charged hydrated protons and water molecules. Understanding these dynamics could lead to polymer membranes that are better engineered for transporting protons while controlling electrode flooding by the water molecules. One of the goals is to develop PEM membranes that need little water.

Using classical molecular dynamics simulations, the research team investigated the impact of four levels of hydration and two different temperatures. The scientists calculated structural properties such as radial distribution functions, coordination numbers, and dynamical properties such as diffusion coefficients of hydronium ions (H3O+) and water molecules.

The results of their calculations showed that protons and water molecules are bound to sulfonate groups in the membrane at low hydration levels. As the hydration level increases, the water molecules become free and form a network along which protons can hop (Figure 2). This leads to a dramatic increase in proton conductivity. Temperature was found to have a significant effect on the absolute value of the diffusion coefficients for both water and hydronium ions. These findings have helped in interpreting experimental results that indicate a major structural change taking place in the membrane with increasing hydration.

In the second paper, the authors used all-atom molecular dynamics simulations to systematically examine eight different levels of membrane hydration to closely mirror two experimental studies. They also simulated bulk water to develop a novel criterion to identify free water in Nafion. This enabled them to quantify the fraction of free, weakly bound, and bound water molecules in the membrane as a function of hydration.

The researchers found that at low hydration levels, strong binding of hydronium ions to sulfonate groups prevents transport of protons. Multiple sulfonate groups surrounding the hydronium ions in bridging configurations hinder the hydration of the hydronium and the structural diffusion of protons (Figure 3). As the hydration level increases, the water molecules mediate the interaction between hydronium ions and sulfonate groups, moving them farther apart. These results provide atomic-level insights into structural changes observed in Nafion by infrared spectroscopy.
