Low-technology Hot in World Expo Sites
Both high-technology and low-technology are on the displaying board in the World Expo sites. The natural low-technology city developing mode exhibited in many pavilions shows a tendency returning to the old times. It also indicates that low-technology can also contribute to the development and harmony of the city, as high-technology does. It means that, aside from the cutting throat high technology, attention should be paid to the connection and regulation of the city.
West Port in Malmo City, Sweden, is a famous demonstration region for sustainable development in the world. The city has perfect infrastructure and most of the local citizens feel they live a happy life there. In the city, low-technology can be found everywhere: grass on the roof can serves as a reservoir to store water and a cushion for the roof against downpour, as well as a air conditioner for the house; in primary school, the kids are planting and watering vegetables and making channels and buildings with water and mud, which serve as the manual training class and processed plasticine.
The visitors queuing before the national grid in the World Expo will feel the chilly wind produced by low-technology. The buildings at both sides prop up a “magic box” suspended in the middle, making a sunshine-free area, in which the visitors can feel the cool wind even under the hot burning sun of June in Shanghai.
There are metal sheets above the queuing group, which produces chilly wind once heated to 80 ℃. Without any resources being consumed or any high-technology being used, the national grid brings the visitors to a sight of harmonious life by low-technology.
Low-technology is a new hot word in the world, referring to the traditional craftsmanship before the industrial revolution. The occurrence of low-technology indicates a tendency returning to the natural and traditional lifestyle in the high-technology oriented life now.
In the Shanghai World Expo, most of the pavilions are covered in green, like the green splint on the Spanish Pavilion. The power of nature is put into use here as an air- conditioner. Two of the best city pavilions, Hamburg, and Rhone-Alps, use plastic window frames to shield heat from outside, a simple but effective technology.
As is pointed out by experts, higher technology does not always make better city. Low-technology is necessary to create a harmonious life, as well as the developed high-technology.
