Onto the roof, Journey Into Amazing Caves

In addition to expanding the use of the roof space, there is an advantage of abundant sunshine, do not worry about lighting issues. Thus, green roofs, rooftop solar controller is through the distance from the sun strengths to achieve people's environmental dreams. The popularity of the concept of green roofs, all the major international cities are popular since the hanging gardens.

Engaged in the cause of more than ten years green roof green roof Association Secretary-General Wang Xianmin world view, green roofs can cure many of the "modern urban disease" - the winter haze, summer urban waterlogging and lead to high temperature heat island effect, can be Green roofs relief, because green roofs help purify the air, rainwater harvesting, cooling insulation.

According to Wang Xianmin observation, Germany is the green roof of the "leader", as early as 1982 began this legislation. Later, Japan, Singapore, the United States, France, are followed, from legislation to encourage green roof. Today, Japan's rate of new construction of green roofs is 100%.

In the specific practices, the German legislation, reported that construction of new buildings must have green roofs, even in rural areas, too, tend to give developers and the government subsidy of 50% to 100% of the green roof construction fees. If there is no roof greening, the government have the means - to close the drainage fee. This is because there is conducive to establishing a green roof rainwater collection system, if the roof bare, will increase the pressure on urban pipeline.

About green roofs, although China is currently no legislation to be encouraged, but Yang Baojun said, as long waterproof, load problems can be resolved, in principle, is encouraged. And Wang Xianmin believes that developers should take up this responsibility, after all, "real estate construction costs greening costs account for only 1/1000", and the construction of a green roof waterproofing system, you can also extend the life of the house, "This is the sustainable development vision. "

In addition to direct green outside, the roof construction of solar energy projects, make full use of clean energy, but also the roof is a major contribution to environmental protection. Or in Germany, thanks to January 1999 from the implementation of "100,000 Solar Roofs Plan", residents have set up buy solar panels on the roof, the electricity in addition to their own use, the remaining can be sold to the grid company, and received power fees. According to 2010 data, relying on the rooftop power generation, some German families can earn 1,500 euros a year.

NASA funded SpiderFab 3D printing space shuttle project hopes to find ways internal components

NASA has always been a leader in the aerospace industry, it is always walking in the forefront of the field, but recently named "SpiderFab" project is to break this tradition. It is the start-up company by the Space Tethers Unlimited's 3D technology and aerospace industry will be combined with the concept of the project.To learn more please visit: http://www.solarpanelcellonline.com/

At the same time, NASA for this project has injected $ 500,000 of funding, and this project will be officially opened in 2020 show.

It is reported that as early as August 2012, Tethers from NASA get a $ 100,000 start-up funding for related research and development. The latest injection of funds will be used for the next two years of research and development. During this period, the company will also develop a device called Trusselator - print using similar techniques used in space solar controller array components.

As of now, NASA has funded a number of 3D space print projects, the agency hopes to be able to find the shuttle internal parts of 3D printing methods. Tethers CEO and chief scientist Rob Hoyt said that once the successful development of this technology, NASA's space components needed to enhance not only the yield on the times, and its print out the parts will have better performance.

Livable + proper industry: core competitiveness of the urban transformation

"Is full of dirty oil, the sky is dust, even the sparrow body is black."

Daqing early development environment, an old citizen recalled, "until 1989, daqing is the first residential buildings."

To make up for the resources development "default", daqing since the "11th five-year plan" put into more than 200 one hundred million yuan for environmental restoration and ecological construction, in accordance with national requirements of pollution emissions at the same time, enforce higher ecological environment protection of the internal control standards, many projects was one ticket veto for eia does not pass.

Now in daqing, oil production sewage recycle all realize recycling, the petrochemical industry wastewater after purification treatment to drinking standards; City canal connected more than 30 lakes, green coverage rate reached 45%; Open and free more than 170 square, for public recreation, fitness and entertainment; Air quality days, 350 days a year or more...

With an open attitude to absorb talents, expansion of population, make appropriate industry environment, the daqing city to strengthen the construction of " dc ac inverter power" as an important content of urban transformation.

Tangle and ill zhuoma youth is daqing make 20 years ago a pair of abroad, from the rented bungalow get married to buy big houses more than 200 square meters, now they experienced entrepreneurial hardships together with city and also share the joy of growth.

Daqing city mayor Xia Lihua said, in recent 10 years in daqing absorb foreign population of more than 50, ten thousand people.

Facts have proven that they have not become a "burden", and for the urban development has injected fresh blood.

+ style: resource advantage of soul

Expected annual capacity of 300000 vehicles Volvo vehicle production base, an annual output value of more than one hundred billion yuan of zhongwang aluminum alloy profile, such as hot, for the project, in the past two years have choice in daqing.

Foreign investors said, the biggest attraction, is embodied in daqing people bear consciousness, dedication and efficient and transparent  solar controller business environment.
