Development of space solar power

Japanese animated series “Mobile Suit Gundam”, the depletion of fossil fuels force the shift of human space-based solar energy development, a new focus of global conflict. In the science fiction world, the background of this era set in 2307. However, the real world, Japanese scientists have now set out to develop rail-related hardware, power generation facilities, as a new, renewable clean energy, is expected to be completed within 20 years.

From space using solar panels, “download” the concept of energy has long existed, it seems impractical because high cost. In Japan, the global energy crisis and environmental concerns for the viability of the plan does not seem to be taken seriously again, last year, Institute of Laser Technology in Osaka produced up to 180 watts of solar power laser energy. In February this year, scientists tested the ground in Hokkaido Electric Power Transmission System, will form a microwave energy transmitted to Earth.

Study of laser and microwave together constitute an audacious plan, Japan’s space agency Japan Aerospace Exploration Agency subordinate (JAXA), presided over the space solar power system (SSPS). By 2030, the agency plans to launch a solar generator to the geostationary orbit, the generator will transfer one billion watts of solar energy the Earth, as a large nuclear power plant’s generating capacity. Solar energy will be delivered in the form of microwave or laser, can be converted into commercial power grid, or stored hydrogen.

Japan’s major research institutions have about 180 scientists involved in this project. JAXA Research Center of the High Representative Hiroaki Suzuki said: “We conducted this study is based on the common-sense reasons – will soon run out of fossil fuels, increasing global warming, these problems be solved.” JAXA said the space solar power has obvious advantages : in space, solar radiation is on the ground 5 to 10 times more efficient collection; 24-hour collection, and is not climate; clean, do not produce pollution and waste, safety and reliability. The energy intensity to reach the ground may reach 5 kW per square meter – about mid-latitudes in summer sunny noon to 5 times. Although scientists say that number will not hurt the human body, but to receive the energy area will be isolated and placed in the sea.

JAXA researchers are testing in progress, hard fiber laser was 800 watts at about 500 meters from the station launched, through 1064 nm wavelength filter only the reflection of light directly at the experimental solar panels. (The reason to use this frequency because it can easily just through the Earth’s atmosphere, loss of less than 10%.) Key task now is to find which can effectively convert sunlight to laser materials, the preferred material as containing neodymium and chromium YAG ceramic materials.

Basic research is only part of the project, testing of microwave and laser systems require a large space equipment: film capacitor filters, solar panels and the effective distance of thousands of kilometers of microwave transmission equipment, which total about one million tons. Terrestrial microwave receiving antenna will also have the 2 km long.

The total project cost may be as much as several billion dollars, but Suzuki and his colleagues say they will not total costs: “Our basic Yanjiu completed, we do not know whether it is feasible. Our goal is to produce energy and hydrogen to stabilize the economy estimated price of 6.5 cents per kilowatt-hour. “This is related to the current cost of conventional electricity rather, in the future will have higher economic value.

In accordance with the present level of technology, large-scale equipment to the space can only be transmitted through the national space agency coordination to complete. Suzuki said that although the potential militarization of space, the trend for countries more inclined to independent research and development of space technology, but “if the JAXA, NASA and the European Space Agency can work together, it would be the best.” Although this all sounds more Prelude like science fiction.

Power battery industry trend growth in Guangdong

In recent years, China's first economic province - Guangdong Province has been promoting the optimization and upgrading of industrial structure adjustment and vigorously develop high-tech industries, advanced manufacturing, encouraging independent innovation, and take the high road of high added value. This guide in 2008, proved to be quite forward-looking. Last year, the international financial turmoil, economic growth in Guangdong, there was greater decline. However, from Guangdong, the first 10 months of 2008 the statistical data, the significant downturn in industrial added value and even negative growth, mainly concentrated in two or three labor-intensive, weak capacity of independent innovation of industry, while maintaining high-tech manufacturing sector is still higher growth rate of 16.6%.

Some closed their doors, even more people would give them see and find opportunities. In the crisis, both to China's largest toy factories, Smart Union toy factory Zhangmutou represented by a large number of low-end processing plant have fallen, but also high-tech enterprise special power contrarian easy expansion, the acquisition of Fortune 500 companies held by Schneider easy special Power System Technology Co., Ltd. 60% of the options, and other cases, more ZTE, Huawei and other companies for many years a large number of high-tech growth.

Battery power is a new high-tech energy and energy-saving products category, data from the relevant departments of Guangdong's power battery industry in 2008 is still growing steadily. All this is thanks to the enterprise optimization and upgrading of industrial structure adjustment. In the current situation, the Guangdong power battery industry, how to go further and take the "crisis" in the "machine", expand markets, upgrade technology, optimize the structure?

Guangdong to enter the international market is still a huge advantage

Power battery industry in Guangdong, a large number of companies have a strong comprehensive strength, their technology, brand, marketing, production and other areas of great strength, in a crisis but could usher in development opportunities, lose ground in the international market. Easy special acquisition of Guangdong 500 companies around the world held by the easy special Schneider Power System Technology Co., Ltd. 60% of the shares. In 2008, the easy special exporting not only not declined, but the first three quarters exports grew 60%. According to Guangdong Zhicheng Champion Group Vice President Bai Yueliang, due to the group active and innovative ideas over the years, persist in doing high-tech products, product sales are still maintained rapid growth.

Although exports, but Guangdong is still the undisputed largest province of China's exports. Power Battery exports is accounted for half of the country. By traders in Guangdong, agents, import and export companies or other forms of direct trade, power battery business export tens of billions of products annually. In addition, the Guangzhou international buyers purchase has been the preferred destination for Chinese products, developed a large number of international buyers to visit the exhibition in Guangzhou to buy the product purchasing habits. Organized by the Guangdong high-profile exhibitions, trade fairs, bidding, etc., power battery companies still have access to find a lot of business opportunities.

In addition, Guangdong due to its unique geographical advantages, will also speed up the realization of China's export market diversification of the bridgehead. In the analysts view, shrinking demand for traditional export markets in Europe and America on the occasion, the power battery business must be scattered in different eggs in the basket, and actively explore new international markets, export market diversification, in order to defuse the rising demand for single market risk bound is the only way. With ASEAN, India, Africa, Latin America and other emerging market trade, compared to other domestic provinces and cities in Guangdong, with transportation, logistics, information and finance a full range of comprehensive comparative advantage. September 2007, Guangdong and ASEAN Secretariat signed a Memorandum of Understanding, to the outside world has brought new markets in Guangdong To speed up the strong signal.

As for the topic shelves and storage space, has pronounced the 308 deserves praise. Not only are there plenty of it - it's all thought out for everyday use. An example: Who is charging while driving, mobile phone or mobile navigation has plugged that in most other cars do not really know what to do with the use of the cigarette lighter. Most of the thing then rolls at every turn through the center shelf. Unlike in the 308th There are right on the cigarette lighter finding the right basin, which otherwise takes sometimes even the money for the parking meter - problem solved.

308 Who goes, who does not need a degree for it: Everything is clear and easy to use. All switches and buttons are easily accessible and intuitive - to use just the switch of the heating, one must stretch a bit. The fashionable circular instruments are easily read. The steering wheel is adjustable in height and length and is well and comfortably in the hand. The materials seem high quality and have a pleasant feel, the workmanship is impeccable.

Under the hood, worked in our test car, a new 1.6-liter VTi petrol engine. VTi stands for variable valve lift and Timing Injection. Behind the concept lies a complicated technology, can be adjusted continuously with the beginning and end of the valve opening times at the intake and outlet and which is to improve by variable valve lift on the intake side of the thermodynamic efficiency. The optimization provides more power and lower fuel consumption. Peugeot says. pcga-bp71 battery

From its 1.6-liter engine pulls the Sun min at 6000 rpm. 88 kW/120 and at 4250 rpm a maximum torque of 140 Nm. That's enough for a top speed of 197 km / h and acceleration from 0 to 100 km / h in 10.8 seconds - all at an official fuel consumption of 6.7 liters per 100 km. In our test, the real consumption is only less than a liter higher. These figures show because in fact an evolution in the 1.6-liter engine of the three-zero-X: The predecessor brought his simple technique to eleven horsepower less, was almost the same acceleration seven km / h below the speed of the new and swallowed yet officially 7.4 liters of gasoline.

The VTi proved to be a nifty runner, cultured and smooth, with enough reserve power for passing on the highway and the rapid progress on the highway. The noise level inside is - based on vehicle class - relatively low. In particular, the engine holds back - which is at a speed of sound, this is especially the wind. pcga-bp2v battery

The suspension absorbs all of the 308 large bumps of the road away casually. The chassis itself is designed rather tightly - which matches the sporty appearance. The 308 remains countermeasures on the straight and consistently without on course. In curves, it understeer a little, helps a pinch early electronics. Pleasant are the strong restoring forces of the steering, which make themselves felt at the corner exit supportive. Otherwise, the control displays clear, accurate and not too smooth. A little more feel for the road we would have wished, however.

The 1.6-liter VTi is available as Tendance version from a base price of € 17 800. He is more than 1000 € with a comparable motor and significantly worse-equipped base about Gulf and on a line with a corresponding Toyota Auris. However, the Peugeot is also the equipment list is long enough to still get rid of a few thousand euros more. lenovo thinkpad x60s battery

Xenon light costs about € 1360 as a package, parking sensors are estimated at € 500, a navigation system is not to have less than 2,150 €. Who wants to go without golf-golf-class boredom, with a Peugeot 308 is well served.
