Not seeking the latest and most unusual but to "affordable"
All begins with the Expo.
It is said that each session of the Expo are some of the protagonist, as a landmark innovation has changed human life. For example, in 1851 the first steam Expo to promote the textile machine, 1878, the lights of Paris Expo, 1893 Expo in Chicago telephone. Indeed, in an endless stream of new inventions of industrial civilization, they are spread as the protagonist of the Expo the world.
If, however, entertain the hope that by 2010 Shanghai World Expo the core theme - Urban Best Practices Area to find, may be disappointed. Here of course there are robots, there are LED lights, there are solar panels, etc., but can not be called particularly "new."
In fact, this is the place the times Expo. Information developed, frequent exchanges of the 21st century, show the latest and most sophisticated technology the stage after another, does not make the Expo specifically the United States. Modern achievements of mankind from the show turned to concern for the environment and sustainable development, shift from simple product display showcase culture and ideas, to people from focusing on a novel inspired to focus on people's lives and ways of thinking, the Expo has opened a new chapter in the history of .
Expo will be "Better City, Better Life" as its theme, the show "art" but also more important to convey the concept of technology: how technology and the process of human civilization and social life more harmonious integration? Sometimes, the technology good enough.
Clever thoughts achievement, "best"
Throughout the region many cases E tablets that were a "clever mind" will gently hit your heart.
Let us look at water from France Alsace curtain Sun City -
Impression is caused by a modern glass curtain wall building "warming" of the culprit, but here it is the key to achieving cool. Glass curtain wall from outside to inside, including three levels, the outer layer may be opening and closing of windows, covered with solar panels, the middle air layer, and finally a layer of water curtain glass. Winter, all the windows all closed, the middle laminated air, in the sun and photovoltaic panels generate electricity under the action of heat, the temperature will rise rapidly, these warm air into the building, can reduce air-conditioning system, heat consumption. In the summer, the outer layer of glass open air; water curtain constantly scouring the inner glass, the middle layer of the air temperature is naturally lower, the same token, can cool the entire building up. At this point, the energy generated by solar panels power source is water curtain, panels themselves can play a shading effect.
Solar photovoltaic power generation, international is a mature technology, cost of power generation is increasingly approaching the traditional coal; pumps, is commonplace; The windows open for ventilation, but there is no technical content of the "knowledge of life." However, through their ingenious combination, can effectively reduce the use of conventional air-conditioning, called "low-carbon model."
Similar examples abound in the best practice area. House in Hamburg, Germany, France Law - Alpes Case Hall, invariably using plastic frames, improving insulation, on the technical content, it is not really high-end plastic frames; Taipei Case Hall introduced the "Zero Landfill" experience in waste separation, incineration, and other aspects of extraction of useful substances, there is not much remarkable new technology, on the contrary, is a careful and detailed management methods to create Taipei's success ...
"The appropriate technology" with great wisdom
Best Practice Area "not seeking the latest, but for the most appropriate", has been widely recognized by Chinese experts. Zheng Ling Chinese Academy of Sciences said, "This show is not necessarily the Expo is a huge novelty device, it could be very useful but obscure technology," The secret to hard to understand.
From the industrial revolution, people are constantly chasing new technologies and new achievements, has made great achievements, and thus profoundly changed the panorama of life. But the pursuit of the application of new technologies also have a scale, extremes meet the law applies. Such as pesticides, came at the beginning is seen as the most dazzling new technology, but since 1962, Rachel Carson in "Silent Spring" in issue "in the wilderness is heard shouting," people realized that "great" pesticides is not as good as imagined. Even today, people want to re-bid farewell to pesticides, is how difficult.
Shanghai Jiaotong University history of science and philosophy of science department head Professor Jiang Xiaoyuan that people's understanding of technology, has long been deep misunderstanding. Especially in China, many people who blindly support the new technology, fearing their own date. Climb cutting-edge science and technology high ground, of course, strongly encouraged, but the objective point of view, the most cutting-edge technology may not have the best application results.
In addition to developing its own technology agnostic, application and popularization of difficult, has become the most cutting-edge technology, "Achilles' heel." Take the example of fuel cell vehicles, as opposed to eagerly look forward to the eyes, it's the pace of industrialization, still seems a bit slow. Of course, application and popularization of fuel cell vehicles must not give up, but a wise city planners, when he wants to build a low carbon city, the city is to choose to use fuel cell vehicles, or combination of hybrid and pure electric vehicles, and then supplemented by a small amount in a specific area of fuel cell vehicles? In the present case, a choice which actually much more effective? The answer is self-evident.
From this perspective, the best practice area shows how good "affordable" technology, called the "great wisdom."
Blind novelty, low-carbon road narrows
Spanish Pavilion with rattan shade; Singapore Pavilion to enhance natural ventilation, reduce air conditioning use ... ... from the Urban Best Practices Area to the Expo site, select "by the appropriate technology" to reduce dependence on complex technologies become a very common phenomenon . Unfortunately, on the people who, "by the appropriate technology" still arrived, but sometimes "cool new" bright light.
Wind resources are not abundant in some areas, in order to show the local new energy technology advanced, rushing to build "new largest" wind farm, hesitate to spend huge construction costs. In fact, the running time of each wind farm is not only limited follow-up grid and other complex issues remain unresolved, and it is almost impossible to really have a "green power." In fact, it is low-carbon technologies, many experts agree that the vast majority of environmental problems to solve today's technology, has basically mastered by humans. Even in traditional coal fields, there are also many technical solutions can achieve emission reduction, but the problem is that these people are not willing to mature technologies and large-scale promotion of rational use, but the blind pursuit of the latest cool, potentially low carbon The road becomes narrow.
Fortunately, Shanghai, this "wisdom" does not lag behind. Back in 2007, the Municipal Science and Technology in the Minhang district of a new residential buildings to promote energy-saving attempt, involving dozens of technology can not be called "the latest and most high-end", but together, energy-saving effect is obvious. Relevant responsible person said, even more play in the future similar to the "combined", the groups of mature technology to launch to achieve maximum application.
In addition to low-carbon hot nowadays, new energy, there are many other areas because of "performance concept," "prestige projects" and other utilitarian considerations, the blind pursuit of "high tech" phenomenon. Some companies, the introduction of the device must be the "most advanced" technology; the contrary, has many years of safe operation of old equipment, old technology, can meet the production needs of the case has been eliminated. Study of its psychological, as if with the latest and most sophisticated technology in order to demonstrate its superiority and a sense of accomplishment. By Professor Jiang Xiaoyuan point of view, technology was originally an important means to achieve sustainable development, and too much reliance on "cool new" technology, in order to achieve "sustainable development", which itself has become "unsustainable" the.
