The Inspiron E1705 is the replacement for a desktop system to cause very stile what users can do based. This is one of its greatest strengths but also weaknesses. Consumers have a clear idea of what the devices are used to buy, if they have them. After all, you can buy in a very limited budget settings at the level of a class of portable game consoles.

Dell is usually well ahead of the curve when it comes to the integration of advanced technology at affordable prices and this time is no different. The Dell Inspiron E1705 Inspiron 9300 multimedia notebook updates with new Intel Centrino Duo mobile technology and many other fine features. Although the focus (both components and performance) is entertainment, the E1705 is the perfect addition to complement the digital home, even for games.

You have two options for the E1705 displays, either a matte WXGA + or UXGA TrueLife style. The E1705 I have is equipped with the UXGA TrueLife screen. E1705 speakers are on the underside of the notebook. The speakers are very good for a laptop and easy to get strong enough to comfortably hear a DVD an entire room. The E1705 processor on this machine works with the review GHz Dual-Core 2.0 - meaning multi-tasking is what this team was born to do. All benchmark results are a laptop E1705 standard - no overclocking or update the driver in fact. The E1705 works well when in a room of about 70 degrees Celsius and is seated at a table, the fan is quiet and capable of dissipating openings when using the laptop for basic tasks in the office.


Dell E1705 Battery Information

dell inspiron e1705 battery

I have a 9-cell battery with the long-term E1705. The standard battery is a 6-cells. Adjust the brightness with Wi-Fi, the Level 3 (maximum 7) and the E1705 for the functions of the light, I’m 2 hours 41 min battery life before the notebook entered forced hibernation, the remaining 5% battery occurs. For a 17 "laptop is actually pretty decent, but considering it was using light (this review write was performed) and Wi-Fi has had to test it very mildly. When you play a DVD and Wi-Fi battery should be about fall 2 hours.. With a desktop-replacement laptop with a fast processor and graphics cards High-End, expect battery life, can be too thin, however. You can do most bettery with a model E1705 with integrated graphics, brightness at minimum and the Wi-Fi - but the funny thing is that when you have a laptop screen 17 may be "just realize that you probably have to hide, say, near a power outlet, and that most of these books are primarily as a desktop replacement there is no doubt in order again, which this application. An interesting aspect is that it pressed a button battery that shows how much charge is left can be. A series of 5 green LED battery lights up and shows you how the battery is full, which is useful when you start your computer, just to see how much battery life left do.

Car battery power to seize the high prices, experts called for calm reflection

Car battery power to seize the high prices, experts called for calm reflection

SAIC project manager of new energy vehicles, said recently that the current SAIC battery development is weak. SAIC chairman Hu Maoyuan said the auto companies should be between joint R & D, "Power battery is very concerned about each company's technology to enterprises in accordance with market principles by the organization of joint research and development, for national support, the development of national standards, corporate Shared R & D results. "

In fact, the car companies and other key components in the battery research and development is relatively weak, and this is precisely the core of new energy vehicles, the largest part of the industrial value, so big hurry Zhengqu Automotive Group is a breakthrough, occupy the high ground.

Zhou Wenjie said the deputy general manager of Dongfeng Motor, Dongfeng future in batteries, electrical and electronic control must have its own core technology and patents, "hoping to control strategic resources." Changan Auto executives said the key components in the R & D, Chang is the most certain electronic control systems, and batteries, electric motors have to find matching system.

Even if the new energy battery is the "boss" of BYD, is also facing battery intellectual property rights. It has always been vested on the BYD iron battery patent challenge. It is understood that BYD currently has thousands of "patent engineer" and a large patent database, patent all possible risks estimates.

The collective experience of the battery car companies prompted the bottleneck problem. Many experts have to face "hot" momentum loudly, hoping to acquire new energy auto companies core technology as soon as possible, and do not ignore the improvement of traditional technology upgrade.

The industry believes that the new energy vehicles should not be simply equated with hybrid vehicles, pure electric vehicles and fuel cell vehicles, and the marginalization of other alternative energy sources, if a large amount of new energy vehicles can not reach but easy to use, it can not be popular.

Car companies have different voices within. Yuan Tao, deputy general manager of Chery Automobile believe that an effective way to solve the problem is to achieve diversification, and should continue to strengthen the traditional gasoline engine fuel economy and reducing consumption. Ford senior technical expert of the original Yang Jialin that the energy conditions are so severe, if not fuel-efficient vehicle power technologies mainstream efforts, it is unrealistic and dangerous. When a large number of foreign low-cost, low fuel consumption of automotive products to enter the Chinese market, independent of the mainstream brands will not be able to compete.

Canon EOS 40D Camera Review


Canon EOS 40D Camera

The EOS 40D is the sixth "prosumer" Canon’s digital SLR, a line that began in 2000 with the EOS D30, and how we did. It is now 18 months since the EOS 30D and if it looks the surface of the 40D because it is a fairly subtle upgrade there are many things that makes a better camera. Of course, we hope that a step in megapixels, so the 40D comes with a CMOS sensor Sensor ten million pixels with the same type of dust reduction as the EOS 400D For ultrasonic platform which shakes the low pass filter. Further improvements to the EOS 40D more in harmony with the EOS-1D series, including a train on the same page after page of the menu system, RAW and sRAW (2.5 MP), 14-bit A / D and 14 - bit RAW, points cross type AF F5. 6 or more rapidly, more and bright viewfinder, interchangeable focusing screens, a larger LCD screen (3.0 ") and faster continuous shooting (6.5 fps).

Canon EOS 40D Camera

This photo of the back of the Canon EOS 40D shows some of the new external functions. The large 3 inch LCD screen is immediately noticeable, especially for owners of the EOS 20D (20D has a 1.8 "LCD). There is a new dedicated AF button on the top right and" Picture Style button (the button right of the screen below). Otherwise, the layout of controls should be very familiar to users of EOS 20D/30D.

True to the line, the Canon EOS 40D is very similar to their predecessors, especially the EOS 30D and 5D. From the rear, but there is one big difference: The 3.0-inch LCD. His influence on the design of the control is returned if he had four big buttons that normally move to the left of the screen, dressed down, below the LCD screen. When it comes to displaying images, Live View composition or change the settings menu is the large LCD.


Canon 40D

The top cover of the Canon 40D is more familiar with only minor differences. The mode dial on the left has some additional icons, C1, C2 and C3, which are areas of convenient storage for frequently used settings, a welcome addition. optimized on the right side of the main difference in a special section on the status LCD on permanent display in the current ISO standard, the word "car" is another interesting addition to the 40D Creative as’ specific skills (is Auto ISO is the default in Full Auto and scene modes). Later, the models should have the ISO button to display the current configuration.

UI measured faster, especially when using manual exposure or exposure compensation settings:

  • two wheels instead of a

  • Excellent durability and protection against dust and rain

  • The largest physical size, the necessary controls in a natural position for most adult hands

  • LCD better or brighter and more

  • (for soccer moms) and the best system for auto focus unit upside faster to capture peak action in a sporting event

As with other modern digital SLRs, the Canon 40D on almost immediately and is very sensitive, a welcome improvement on a typical point and digital cameras.



Although none of the cameras to support AA batteries (which some, including myself, prefer) of the box, which support some of their optional battery grips.

Would the battery life better? Then take the battery grip BG-E2 news. This has two BP-511A or six AA batteries, twice the battery life of the camera alone. You can use Grip BG-E2 of the age and use - the difference is that new watertight compartments with climate. Both clips are additional buttons that are practical for inclusion in the portrait orientation.

If you shoot in portrait mode, especially when taking in that long, a portrait of accessories / vertical grip is a great victory. It gives a much more comfortable and stable "dslr battery grip" on the camera body. There are many shooters for the Canon EOS 40D are (they attach to the bottom of the unit as shown above). The first 20D/30D to handle - the Canon BG-E2 (now deleted). The second is new at this time Canon BG-E2. Add This handle is not surprising that the "AF-ON", but a little time stamping.

Solar cells

Principles of solar cell power generation

Solar cells is a response to light and can convert light energy into electrical power devices. Photovoltaic effect can produce many kinds of materials, such as: silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium selenium. They are basically the same principle of power generation is now crystal as an example to describe the light generation process. P-type crystalline silicon doped with phosphorus can be obtained through N-type silicon, the formation of P-N junction.

When the surface of solar cells exposed to light, the part of the photon absorbed by silicon material; photon energy transfer to the silicon atom, the electron transfer occurred in Vietnam, becoming free electrons in the P-N junction potential difference formed on both sides of gathering, when the external access through the circuit, under the effect of the voltage, current will flow through the external circuit to generate a certain output power. The essence of this process: photon energy into electrical energy process.

About Sun

The sun is the nearest star from Earth is the center of the sun object, its mass accounted for 99.865 percent of total mass of the solar system. Sun is the only solar system objects in their own light, it brings light and heat the planet. If there is no exposure to sunlight, the ground temperature will quickly drop to near absolute zero. As sunlight exposure, average surface temperature will be maintained at around 14 °C, the formation of the human and the majority of biological survival. In addition to nuclear, geothermal and volcanic energy, the ground most of the energy are directly or indirectly related to the Sun.

The sun is a mainly composed of hydrogen and helium gas hot fireball with a radius of 6.96 × 105km (109 times the Earth radius), mass of about 1.99 × 1027t (33 times the Earth mass), the average density of about Earth 1 / 4. The effective temperature of the sun's surface 5762K, while the internal temperature of the central region and up to tens of millions of degrees. The sun's energy comes mainly from the hydrogen fusion reaction together into helium, there are 6.57 × 1011kg per second polymerization of hydrogen helium 6.53 × 1011kg, continuous production of 3.90 × 1023kW energy. The energy form of electromagnetic waves to 3 × 105km / s speed through space shooting in all directions. Global solar radiation the Earth receives only one half of 2.2 billion, that is 1.77 × 1014kW reach the Earth's atmosphere on the edge of the ("upper bound"), due to the attenuation through the atmosphere, the last of about 8.5 × 1013kW reach the surface, this generating capacity equivalent to the number of dozens of times around the world.

According to the current estimated rate of nuclear energy produced by the sun, hydrogen is sufficient to maintain reserves of 60 billion years, Earth's internal organization of the polymer into helium by thermonuclear reactions, it is about 50 billion years of life, so in this sense, it can be said of the sun energy is inexhaustible.

Sun's structure and energy transfer methods are briefly described below.

Great mass of the sun, the sun's own gravity, solar material gathered to the core, the core center of the high density and temperature, making the nuclear reaction can occur. The nuclear reaction is the sun's energy, the energy generated by continuous radiation to space, and control the activities of the sun. According to various indirect and direct information, that the sun can be divided from the center to the edge of the nuclear reaction zone, radiation zone, convection zone and the solar atmosphere.

(1) Nuclear reaction zone

25% of the solar radius (ie 0.25R) in the region, the core of the sun, focusing the sun more than half the quality. Here temperature is about 15 million degrees (K), atmospheric pressure is about 250 billion (1atm = 101325Pa), the density close to the 158g/cm3. This part of the total energy generated by solar energy produces 99% of the total, and radiate outward convection and radiation methods. Emit gamma-ray polymerization of hydrogen, these rays through the colder areas, energy consumption, increasing wavelength, into X-ray or ultraviolet and visible light.

(2) radiation zone

Outside of the nuclear reaction zone is the radiation zone, belongs to range from 0.25 ~ 0.8R, the temperature dropped to 13 million degrees, the density dropped to 0.079g/cm3. The energy generated in the solar core from the radiative transfer through out the region.

(3) convective zone

Outside the radiation zone is the convection zone (troposphere), belongs to range from 0.8 ~ 1.0R, the temperature dropped to 5000K, the density of 10-8g/cm3. In the convection zone, the energy spread mainly by convection. Inside the convection zone and part is invisible, they can only rely on the nature of observation consistent with the theoretical calculations to determine.

(4) solar atmosphere

Can be divided into ball of light, color ball, corona and other levels, all levels have significantly different physical properties. The lowest level of the solar atmosphere called the photosphere, the sun almost all the energy given from this level. Continuous spectrum is basically the sun's photosphere spectrum, absorption lines within the solar spectrum is basically formed within this layer. The thickness of the photosphere is about 500km. Chromosphere is the solar atmosphere of the middle, is the outward extension of the photosphere, has been extended to thousands of kilometers can be high. The outer solar atmosphere called the corona, the corona is extremely thin gas shell, can be extended to several solar radii away. Strictly speaking, the only form of stratified solar atmosphere the significance, in fact, does not exist between the layers is a clear boundary, and their temperature and density with height is continuously changing.

Visible, the sun is not a certain temperature blackbody, but the many layers of different wavelengths of radiation, the radiation body. However, in the description of the sun, the sun as the temperature is typically 6000K, 0.3 ~ 3.0µm wavelength of the black body radiation.

Recent development of solar energy utilization

Has learned from the Shanghai Science and Technology Commission, East China Normal University researchers using nano-materials in the laboratory success "recycling" chloroplasts, in a very low cost to achieve energy generation.

Chloroplast is the site of photosynthesis of plants, effective conversion of sunlight into chemical energy. The research group of plants in vitro is not "copy" of a chloroplast, but developed a similar chloroplast structure and a new battery --- dye-sensitized solar cells, convert light into electrical energy trying. In Shanghai Nano Special Fund's support, after 3 years experiment and explore, this bionic photoelectric conversion efficiency of solar cells for more than 10%, nearly 11% of the world highest level.

Project Manager, East China Normal University is satisfied with the advanced equipment Optoelectronic Integrated Engineering Research Center, Ministry of Education, Professor Sun Zhuo demonstrated a new type of solar cells, "sandwich" structure sandwiched a layer of insulating glass nano --- "sandwich", photoelectric conversion of the mystery hidden in this layer tens of microns thick composite film. Nano "sandwich" and "formula" is unique: Dye to act as "light-harvesting hand", nano titanium dioxide is a "media converter." Dyes as much as possible in order to "eat" the sun, researchers even inspired to spread the point "sauce" --- a fluorescent material by the nano-dots, so that different wavelengths of light can be on a "fishing light hand "and" appetite. " Continue to improve as long as the "recipe" nano "sandwich" of the photoelectric conversion efficiency can be improved again and again.

As a third generation solar cells, dye-sensitized cells is the biggest attraction of cheap raw materials and simple production process. It is estimated that the cost of dye-sensitized cell silicon solar panels equal to only 1 / 10. At the same time, it less demanding lighting conditions, even in the sun is not enough room, the photoelectric conversion rate can not be seriously affected. In addition, it also has many interesting uses. For example, using plastic instead of glass "plates" can be bent into flexible batteries; to make it into the monitor, you can side of the power generation side of the light, to achieve energy self-sufficiency.

Solar energy is a clean and sustainable energy, development of solar energy in the power generation process to reduce use of fossil fuels, thereby reducing air pollution and global warming.

The T500 ThinkPad is the latest update from 15.4 to long-term Lenovo T series. The combination of the latest generation of Intel goodies, ATI Hybrid, and DisplayPort connection this notebook has to offer many new things in previous ThinkPads. With all these changes in place, Lenovo remains the same version we expect, or quality standards slipped through the cracks?

T500 (incomplete) Centrino 2 based on the platform and you can read our review of the Centrino 2 platform HERE. Lenovo has decided to use an Atheros wireless adapter instead of Intel, and therefore there is no certificate T500 Centrino. Notebook is the latest generation of Intel processor that has great benefits (2.53 GHz, 1066 MHz FSB) and fast hard drive forever, of course. Resolution 1920×1200 (WUXGA) matte screen on the 15.4′’seems almost unreal. Of course, not lose many words about the quality of the image, but it really is true delight graphics subsystem.



ThinkPad T500 Specifications:

  • Display: 15.4 "1680 x 1050 WSXGA + LCD (Matte)

  • Processor: Intel Core 2 Duo T9600 (2.80GHz, 1066MHz FSB, 6MB cache)

  • Memory: 2 GB of DDR3 RAM

  • Storage: 160 GB hard drive (7,200 rpm)

  • Optical Drive: DVD + /-RW

  • Wireless: 802.11b / g, Bluetooth 2.0

  • Graphics: ATI Mobility Radeon 3650 with 256 MB or Intel X4500 integrated (hybrid switching)

  • Integrated webcam

  • Battery: 9 cells (84 h W nominal, real 81Wh)

  • Dimensions: 14.1 x 10/10.9 "x 1.8"

  • Weight: 6 lbs 7.2 oz (w / 9 cell battery)

Lenovo currently offers two different views for the T500. The first is a panel with LED backlight WXGA 1280×800 and the other is a 1680×1050 WSXGA screen. The panel WSXGA significantly higher compared to the same work area and resolution, especially when working with multiple windows open. LED panel on the other hand, has a higher brightness and better lighting.

However, if you really need much space for CAD programs or image editing, the WSXGA panel may be limited, and you’d better take a look at the series ThinkPad W500, a WUXGA (1920×1200 pixels) offering.

Our test model was equipped with a 1680×1050 WSXGA slab. It reaches a maximum value of 203cd / m in the central area of the screen, and meets the manufacturer’s specifications of 200 nits (cd / m²).

Although the brightness was in the viewing area in the upper left, at least 169.4cd / m², the screen is a good illumination of 83.7%.

lenovo thinkpad t500 battery

Lenovo Thinkpad T500 usually contains a rechargeable lenovo thinkpad t500 battery 6-cell lithium ion with a capacity of 5200mAh (56.16Wh). In addition, there are also a 9-cell battery and Ultrabay battery available. The larger 9-cell primary battery is identical to the T61 models and get a small lift in the back of the notebook. What the 9-cell battery, however, the T61 Ultrabay battery models used in the ThinkPad T500. However, it is possible to define a T500 Ultrabay battery in the Ultrabay slot of a T61 model.

6-cell battery is not unique to the case and moved a little. The portable T500 was able to run the battery test units high (minimum brightness, the energy saving mode, compared to WLAN) to a maximum of 276 minutes with 6-cell battery. Under load, the battery test Eater Classic (maximum brightness, maximum power and more power), which took only 61 minutes to drain the lenovo battery. Both results were obtained with the graphics card active. In addition, ATI PowerPlay with disabilities in the conventional test, the laptop delivered the same performance as if it had been inserted media

The autonomy of the T500 in the classical test has increased by 82 minutes with integrated graphics, which represents an increase of 22 minutes. The energy consumption shows that Thinkpad T500 consumes less power 3.5 W with integrated graphics, compared with the dedicated ATI graphics card. The low consumption of the chip is also significantly under load.

New Energy Business Unit Sales Manager Wang Zang Yin told the "Science Times" reporter: "This exhibition shows the contents of a more integrated, with the battery show this platform, we not only can expand their visibility, enhance enterprise image, but also upstream and downstream enterprises to establish good contacts, from the perspective of the battery industry to seek greater development. "

Coast Electric Vehicle Co., Ltd. Tianjin, the staff, the company booth come to understand the situation of the audience flocked to their products, staff too busy to even have no time to eat. In particular, this exhibition is the leading product - a new generation of lithium battery electric vehicles Century wind 2, and so on, entirely developed by the Chinese themselves design, long battery life, lightweight, portable, has received high attention.

Accelerate technological upgrading and product upgrades

Since 2002, China's battery production and exports increased considerably, with 76% for export. By the international financial crisis, since the second half of 2008, China's battery industry growth rate of exports has continued to decline, battery sales increase in accounts receivable, economic decline. With mobile phones, cars, electric bicycles, and other ancillary products production and sales shrink the battery, the battery output growth to fall.

Some show business staff told reporters that the difficulties now faced by enterprises is mainly caused by the increase in battery costs less competitive market, corporate profits dropped significantly. Meanwhile experts also said that China's battery are highly dependent on international markets, especially in solar cells, 95% of exports, 90% dependent on imports of raw materials, this "two out" of the market risk is too high, also caused Industry profit-shifting. Relatively backward industrial base of raw materials, key materials still rely on imports, China's high energy consumption and pollution is very low in exchange for economic benefits. Solar cell manufacturers such as the average profit margin is only about 8%, if the deduction of export tax rebate, the enterprise unprofitable. Experts suggest that should be resolved as soon as possible domestic production of crystalline silicon materials and solar domestic consumer market.

Reflect the number of enterprises, large output of the battery, but the cost is not high. For example, the average price of Japanese chewing gum battery is 3 dollars / only, South Korea and China Taiwan produced about $ 2 battery / only, while the same cells produced in mainland China is only $ 1 more / only, less than the price of Japanese products half. Experts said that China still needs some improving product quality batteries, battery industries need to upgrade technology, the structure of some products such as electric vehicle batteries, zinc-manganese batteries urgent need adjustment.

To completely industrial upgrading

Earlier, the Battery Association has proposed to encourage the development of "green cells and renewable power" to encourage businesses to have the resources and market advantages of countries set up factories in the policy. The next few years, China's battery industry will focus on structural adjustment and industrial upgrading, and effective anti-risk ability to improve industry and international competitiveness, improve the capacity of independent innovation and brand building, innovation in the industry to establish a sound support system, and further implementation of the technology and equipment , market diversification and accelerate the world's manufacturing power by the battery industry to manufacture the world's power forward.

Physics, Chinese Academy of Sciences Academician Chen Liquan said the establishment of National Research Center for the battery industry, integration to improve overall industry capacity for independent innovation, promote technological progress, we should focus on breakthroughs in battery electric vehicles, car key battery materials, key technologies and research and industrialization.

China's huge market for electric bicycle lithium ion battery industry has brought opportunity. Physics, Chinese Academy of Sciences researcher Professor Huang Xuejie, said: "Every year more than 2000 million electric bicycle sales, the entire electric vehicle industry is a huge boost. It is no exaggeration to say that China's four wheels and an electric car by two wheels and is carry the electric bikes come. "

He expects the next few years, not only the electric car industry needs its own development, China's lithium-ion battery industry will usher in a comprehensive technology upgrade. By 2010 years ago, the lithium ion storage battery materials will enter the industry.

"The battery is the most critical components of electric vehicles is the result of pooling multi-disciplinary research, enterprises need to focus on supporting the Government the choice of quality." At the show, many companies have made such comments.

It is understood that the Government introduced in this area related policies, including the establishment of the battery industry standard access card management system, the battery industry to radically improve the risk of emissions to protect the health of workers labor; create financial incentives to support electric vehicles cells, wind power and solar energy storage battery development, and implementation of clean energy; adjustment of export policy, stability, battery export trade, the establishment of waste battery recycling industry alliances, establish and regulate the waste battery recycling operation, and effectively protect the ecological environment.

It’s the same price as the average netbook. enter the market at a price so low is an exciting step for Dell, which makes them in the same group as the computer manufacturer Emachines budget and Medion. but he has lost in recent years, manufacturers like Dell place the world’s largest PC (HP, no less), retrenched workers, and announced a huge drop of 48% of turnover .

Design is minimalist and sleek. Besides the keyboard and touchpad are the only things that break the clean lines and spokesman for the chrome grille Inspiron little square power button on the keyboard. In 1545, the first signs of the economy of nature, not even a webcam in booty flat screen bezel. To be honest, it’s a bit hard to a fault on a laptop about 400 pounds, that even the cheapest netbooks come with a. And although Dell offers a 1.3 megapixel model to update, if the purchase in 1545 of direct taxes is 30 pounds heavy for the privilege.

US-developed thin-film solar cell tape

US-developed thin-film solar cell tape

A U.S. company created the first "fast power light," developed a large-scale manufacturing technology of solar panels can be curled. The tape-style stainless steel sheet manufacturing technology can be formed in the amorphous silicon thin film solar cells. Each solar module is about 1 meter wide, 5.5 meters long.

Compared with traditional silicon solar panels the image of heavy and hard, these lightweight panels can be curled easily integrated into roofs and facades of buildings can also be used outside the vehicle body. The solar panels more attractive than the traditional place that can more easily be embedded irregular design of the roof.

The company's founder and president of Deng Ming Xun (phonetic) said: "They can even be rolled up with a backpack, so you can use it to recharge your laptop."

Amorphous silicon thin film solar cell battery than the more expensive traditional crystal, because it just part of the materials used, compared to crystalline solar cells 150-200 mm thick layer of silicon, its thickness of only 1 mm. However, its drawback is that efficiency is very low. In order to improve its efficiency, fast force energy companies created a tripartite structure of the battery, which consists of 3 different materials - amorphous silicon, amorphous silicon germanium and nanocrystalline silicon - is made of each material to be tuned to capture the energy of the different solar spectrum.

Although some of the market efficiency of crystalline silicon modules up to 20% or more, while the fast forces can be coiled energy efficiency of photovoltaic modules is only about 8%, but its advantage is that the volume of high-capacity tape technology. Tape and Reel technology allows it to reduce costs, expand the scope of application.

So far, fast force energy has been invested 4,000 million, December 2008, Ohio has given the company $ 7,000,000 in loans to accelerate the construction of a 25 megawatt solar module production line curl. The company is expected to be formally introduced to the market in 2010 and its products.

Study - 74 percent would buy an electric car

Study - 74 percent would buy an electric car

According to a recent study by the Automobile Club ADAC could be 74 percent of respondents think an electric car to buy and about 90 percent are electric vehicles a positive attitude. As a prerequisite, however, should not, however, more expensive mobility compared to normal drives significantly. In the space, the reach and power, it should not come, however, were noted to reverse progress.

According to estimates by experts, will be made for the global new car share in terms of electric and hybrid vehicles in 2020 to five to ten percent. The automakers are developing electric cars and will get some already this year on the market. The ADAC urges automakers to adjust to not rely solely on electric motors, because the fuel consumption in internal combustion engines can be reduced even further. The electric cars will be established only on the car market when the range increases, prices will be lowered and a power station network is being established.

TUV Rheinland electric car endurance test

The testing service provider TUV Rheinland has now begun a long-term test with the micro-electric car Vett Fiorino E and the energy group RWE AG leased. On the site of the Cologne headquarters, a quick charger with 400 volt power was established. The electric car is based on the Fiat Fiorino. "This is a roughly three-year trial begins in practical operation. The car has to make its practicality and reliability of evidence, potential weaknesses and problems, we are clearly documented in this time, "said Prof. Dr.-Ing. Jürgen Brauckmann responsible for TUV Rheinland for the mobility.

Going to recent studies more than 80 percent of car owners a day less than 100 kilometers and thus would be the performance of today's lithium-ion batteries sufficiently. The vehicle Micro-Vett Fiorino E runs environmentally friendly because the charging station gets its electricity from renewable energy sources. The test will last for three years in the framework of the electric car is widely tested in everyday use. After the objective of the testing service, electric cars are as safe as regular cars.
