Solar Chat

Japan Aerospace Exploration Agency will be launched next year, a small pilot solar sail spacecraft, “Ikaros”. Solar laptop attery sail spacecraft in order to reflect solar particles into motivation. “Ikaros” with the Venus probe “Daybreak,” with by the H2A rocket into space.

Solar sails do not need fuel, 100 years ago, humans had this idea, but the lack of strong lightweight materials and can be extended a large area but did not materialize. “Ikaros” solar Toshiba laptop battery sail for the side length of 14 meters square, only 0.0075 millimeters thick, able to withstand the space environment from the polyimide resin, weighing about 15 kilograms.

As the polyimide resin is usually yellow, sails need to spray the surface of aluminum foil to enhance the performance of the reflection of sunlight. “Ikaros” in order to sail solar particles hit surface resulting from the reaction as the driving force, by VGP-BPS8 adjusting the sail surface and the sun’s angle control speed and trajectory. The researchers also plan to “Ikaros” about 5% of the surface, installation of thin-film solar cells for the future development of ion engines and hybrid solar sail spacecraft to explore Jupiter’s technical reserves.

Solar sails would be rolled in diameter and 1.6 meters, 1 meter high cylinder-type body on the spacecraft launched into space a few weeks later by the centrifugal force generated by rotating the spacecraft launch. First, the pilot VGP-BPS9 solar power solar sails can be achieved, followed by six months to test their ability to use the sun as a driving force for particle acceleration and orbit, in order to accumulate data for future applications.

U.S. Planetary Society in 2001 has created a solar sail spacecraft testing, but the rocket failed. The association plans to launch by the end of 2010 new solar sail spacecraft, “light sail on the 1st laptop battery.” The European Space Agency is also under study solar sails. If the “Ikaros” trial is successful, will set a precedent in the history of human spaceflight.

Japan: National response to climate warming

Affected by natural conditions, geographical and environmental constraints, the impact of global warming on Japan is much larger than other developed countries DSLR Battery Grip, Digital Camera Battery. To this end, the Japanese established a public participation mechanism for response to climate warming, from the consciousness and the technical level to promote energy conservation, new energy development schemes.

According to the findings, if not to curb global warming, the 21st century, Japan’s maximum temperatures exceeding 30 degrees Celsius throughout the year the number of days will increase to two to three times the current. Temperatures also resulted in rising sea levels, while the Japanese coastal city of about half of the population concentrated in the country.

Affected by rising temperatures, the Japanese famous “Koshihikari” rice for 50 years, will cut 10 percent, while rice dysplasia, quality will fall. Japan’s food self-sufficiency rate is low, climate warming on the world’s major grain producing area, especially for the Asian monsoon Canon EOS 450D Battery Grip with the impact of food production, there is a greater fluctuations in food production will affect food security in Japan. Global warming, sea temperatures and atmospheric carbon dioxide into the seawater but also in seawater floating plants and animals, as well as fish, shellfish and other potential impact.

The 20th century, 70’s two oil crises prompted the building of energy-efficient countries, Japan has taken the pace, but now a growing number of Japanese people understand that reducing energy consumption is still the main way of greenhouse gas emissions.

The Japanese to buy something, we will repeatedly purchase products are more energy-efficient. Buy a car, many people tend to fuel-efficient small cars; to buy electrical appliances, they would rather the price slightly expensive, they must also select energy-efficient. Japanese companies Canon EOS 500D Battery Grip have also attached great importance to the development of energy-saving technologies, and constantly introduce new in the field of energy-saving products. At present, the vast majority of air-conditioning electricity consumption in Japan and 10 years ago has declined by 50% to 70%.

In the throttle at the same time, Japan also tried open source. At present, Japan is accelerating the development of renewable energy, reduce oil, coal and other fossil fuel usage. For example, the main hydrogen as fuel in the domestic fuel cell cogeneration system has entered ordinary Japanese homes. It is estimated that a group of fuel cell can make a family’s annual greenhouse gas emissions by 40%.

Japan’s solar capacity ranked second in the world after Germany, the world’s tenth column of wind generating capacity. The use of bio-fuels in power generation has also made rapid development in Japan has reached 100 percent utilization of waste paper pulp, wood processing waste utilization reached Canon EOS 1000D Battery Grip 90%, livestock manure utilization of 80%.

In addition, Japan is also actively developing carbon dioxide recovery technology. Japan’s industrial technology research institutions, the Earth’s environment since 2003 the city of Nagaoka in Niigata pressure of carbon dioxide into the 1,100 meters underground aquifer tests in 2005 has been successfully pressed a 1 million tonnes of carbon into the ground, equivalent to 2500 cars a year emissions of carbon dioxide.

Settled in large-scale amorphous silicon thin-film battery project Cixi

From Zhejiang Ci to Photovoltaic Technology Co., Ltd. invested 10 megawatt amorphous silicon thin-film battery project settled in Hangzhou Bay New District, held a signing ceremony yesterday morning. Ministry of Science and party members, “Science and Technology Daily” News Agency ZHANG Jing, national strategic high-tech Program (863 Program) Expert Advisory Group consultants Ma Junru attended the Nikon D40 Battery Grip signing ceremony.

The project is the State Science and Technology, Ministry of Finance and other departments in 2006 promulgated “China’s high-tech products directory” listed in the project, a national advocate and encourage the green renewable resource industries, with a total investment of 21.76 million U.S. dollars, is expected to be completed and commissioned after the end of the year annual output of 10 MW of amorphous silicon thin film photovoltaic cells of large glass, the annual sales income can create 50 million U.S. dollars. Settled in this project also means that in order to Hangzhou Bay New District to build wind power generation equipment, solar photovoltaic cells, etc., represented by the green energy R & D, manufacturing base to enter the substantial start-up phase.

After the signing ceremony, also held a New Energy and Industrial Vision and Nikon D40X Battery Grip Application Conference, from Shanghai Jiaotong University, Nankai University professor on the development and application of new energy sources gave a special lecture.
