Low-carbon green energy-saving environmental protection recommended by the InternetWith the “LOHAS” is the prevalence of green ideas have been getting deeper and deeper into the consumer’s life, whether it is food, clothing, or the IT categories of products,Dell latitude e6400 battery are more and more companies have chosen the low green carbon as the main idea of future products. The development of notebook computers today, its various services have reached a very high level, great to meet the practical needs of the consumers, but the laptop’s “green” targets simultaneously has been not able to keep up with, this can not be do not say is a pity, but also notebook computer industry continue to develop the real bottleneck, the major notebook manufacturers have become the greatest confusion.”Green Notebook”, by definition, refers to the ability to have the laptop energy saving, green notebook in providing convenient service for people, it is also possible to overcome all kinds of human health, environmental protection pose a potential threat to environmental issues.

Speaking of green notebook, can not fail to analyze most of today’s notebooks have to face the problem of environmental pollution, most of today’s notebook in the case of raw materials selection, screen quality, model design, battery and other aspects of election materials are the existence of environmental problems, large and small, to create a true full green notebook, you have to start from the above aspects, in order to resolve their achievements within a real environment the concept of green notebook.

First, the material.

Under the current classification of shell material, notebook shell can be divided into two categories, one is non-metallic materials, one is alloy. Generally, there are non-metallic materials: ABS plastic, polycarbonate and carbon fiber. Generally, there are magnesium alloy and carbon fiber titanium alloy. Most notebooks now use the majority of middle and low is the non-metallic materials, particularly now that some of the low-end notebooks are still using ABS plastic that serious harm to human health and the environment of the material.

ABS plastic commonly used in low-end computers, this is because of its low cost and can create stronger, but the cooling performance is very poor, in the hot summer months make the system run continuously for a long time to use unstable, and even lead to crashes, and overheating in the case of long out of harmful volatile gas. In addition, ABS plastic radiation shielding ability, using this laptop for a long time inevitably close to the body by radiation damage, seriously affecting the health of the user.

Polycarbonate ABS plastic, although not many side effects, but they belong to the same plastic products, in addition to gas produced in the hot environment, there is the difficulty of degradation. Whether or polycarbonate shell with ABS shell will be used notebooks high levels of pollution on the environment.

Second, the screen.

Lightweight for portability from the current mainstream notebooks on the market have adopted the TFTLCD as a screen. TFTLCD mainly by the LCD panel, TFT drive arrays and backlight system. Liquid crystal display materials as a major flaw is that it itself does not light, therefore, must be used in liquid crystal display backlight. Typical laptop LCD screen, the most used CCFTColdCathodeFluorescent Tube as a cold cathode fluorescent tube backlight, CCFT brightness is high, but the disadvantage is the need to high-voltage AC drive, and contains environmental, health, harmful mercury.

In addition to health hazards, energy consumption is CCFT not the perfect place to another. As with CCFT backlight notebook laptop computer screen energy consumption accounts for 30% of energy consumption, it will not only shorten the laptop battery life, and is a direct waste of electrical energy.

Currently, the use of LED backlighting has become an alternative to CCFT. First of all, energy is the most significant advantages of LED, incandescent than normal 60% -80% savings in electricity, more than 50% of the energy saving fluorescent lamps. It uses low-voltage power supply, thus more secure. Secondly, LED is not the presence of mercury, so no environmental pollution. However, LED’s promotion also has some difficulties because: on the one hand, LED brightness is not strong enough, it is appropriate to large-screen LCD screen; In addition, LED backlighting system, the cost is higher than the cold cathode fluorescent tube. Nevertheless, in 2005 Toshiba launched the first super-mini-notebook LibrettoU100, has for the first time the introduction of LED backlight system, notebook computer, to achieve the energy saving and environmental protection, which gives us good hope to see the LED.

The notebook LCD panel is divided into A, B grade, C grade and other specifications, more use of low-grade or poor quality laptop defective B, C-level panel, the viewing angle is small, there are a lot of dead pixels, and the emission of radiation great, very easy to aging backlight, resulting in distortion of the screen colors dimmed, these constitute fatal flaws are extremely harmful to the health of the user eyes.

Third, the battery.

Notebook computer battery is a very important component, without it, the notebook can be said to be unable to move, lost due flexibility. Laptop battery has gone through times of nickel cadmium, nickel hydrogen age, lithium-ion times, with the notebook computer technology, battery technology has made substantial progress, the current types of notebook lithium battery life of up to 2 to 4 hours.

In general, the battery during operation will not cause direct harm to humans, but once the battery for a long time are not used properly handled will have an enormous damage to the environment. Entertainment laptop now tend to clear their amazing energy, which greatly reduces the already short-lived lithium battery life, resulting in a notebook battery life is short, frequent replacement, thereby increasing the pollution of the environment of such articles intensity.

Notebook computer batteries to be green, simmering quarrel before the fuel cell is a good solution. Both non-polluting fuel cells, efficient, widely applicable, no noise, can work, etc., and the work product of only water and heat, pollution, high efficiency, is a clean environmentally friendly power, compared to commonly used lithium lithium polymer batteries and to clean, environmentally friendly. In addition, the fuel cell has a higher energy density, in the case of the same capacity, the battery can be made smaller or the same size and weight of the battery case, Dell studio 1557 battery capacity to do more.

However, fuel cells, there are also some drawbacks: First, the cost is too high. At present, the fuel cell to generate hydrogen at low temperatures required for the cost of expensive platinum catalyst, and its low power density. Relative to the overall cost of lithium batteries can not be compared. Second, fuel cells and lithium batteries we used different fuel cell is not charged, to sustain the supply of electricity, can only add fuel electrolyte method, how to allow users easy access to these fuels, there is a certain difficulty. Third, the start time. Preheat the fuel cell needs a time to meet our power requirements. Fourth, the output problem. Fuel cells in the course of it can not provide a very stable output in the middle of a stage will be drastic decline. It seems that the notebook fuel cell in order to be widely used on the need for further research and development, but we believe the prospects for fuel cells is very bright, as low pollution, high energy density of the product, it laptop battery on Energy paints a really good prospect.

At present, the efforts of companies, fuel cell applications in the notebook computer technology has also been a rapid promotion. We believe that fuel cells is expected to achieve in the next few years, product, practical, popular. The industry generally believed that early fuel cell generally can provide 6 to 8 hours of operating time, as the technology matures, to longer periods of time is just around the corner.

Fourth, energy consumption.

High development of science, technology, notebook computers can also be armed from a variety of multimedia equipment, the more it tends to the direction of entertainment, high-performance CPU, graphics card, high-speed hard drives, more wide-screen, synchronized range of additional equipment, so that the overall energy consumption of notebook computers has reached an unprecedented height. Although Intel’s energy-saving technology in the support, but the time when there is power, and who would think to give up their power of entertainment to enjoy it?

Therefore, the more absolutely contrary to the direction of the corpus of the production of notebook computers, notebook PC manufacturers should work to make a small light to the development of energy-saving products, while renewable energy such as fuel cells can tolerate the promotion of arbitrary power laptops increase, but energy conservation is, after all, an important requirement of environmental protection, green notebook is one of the fundamental characteristics.

Fifth, design.

We all know that laptop notebook production mold design is an important part, generally only the big vendors have developed new molds. Excellent addition to mold itself to consider the technical requirements of notebook computers, have ergonomic requirements, the current situation is: OEM common with a number of public and Die design flaws, rough appearance, popularity, the keyboard keys do not mix Ergonomically designed, the keyboard is easy for some narrow the user’s hand joint inflammation, there is the screen size possible design errors, which also makes the user’s eyes in a very short period of time produces fatigue, to a certain extent affect the health of the eye.

Due to technical constraints, we are able to more easily achieve a breakthrough on power and materials, Internet products in this class of notebook is one of the typical environmental, here we recommend several green products.

Renewable green energies become imminent trend in coming 50 years in Britain. In using demonstrated products such as solar keychain flashlight, solar lantern and dynamo torch and devices not only can help you to save up money but also to save the earth. Because millions of abandoned small batteries and CO2 can be slashed. Products can be tailored made to company logo and advertising words that not only can help renewable energy companies to promote their green products but also to educate public that solar power (photo voltaic) can produce energy in cloudy days also.
