Driverless cars, recycling of rainfall and biodegradable roofs made from soy beans – novel as they sound, there is an annual event where they can all be found all at the same time and place: world fairs.
These environment friendly features fit well with the next world fair, this time to be held in Shanghai. Some 200 countries and international organizations will go to the Chinese city for the Expo 2010 that will run from May until October.
“I heard that the Japan pavilion was made of a special thin material that can generate electricity on top, while the Switzerland pavilion is made of soybean fiber that can both generate electricity and be degradable,” said Wan Gang, China’s minister for science and information technology.
“It sounds novel to me, and we should seize the opportunity to learn the new technologies of the world,” he added.
The Shanghai World Expo 2010 will show the latest clean energy technologies and products. But the event itself will try to be green.
Electricity generated from 4.6-megawatt solar power generators will power the five-month long event, said Mr. Wan.
Another 34 units of 3-MW wind power generators currently under construction will help provide electricity for the 5.8 kilometer exposition site that will house an estimated 70 million visitors.
Energy-efficient L.E.D. lamps will light the expo’s four pavilions, the China Pavilion, Theme Pavilions, Expo Center and Performance Centre. Pavilion-making has traditionally been must-see features at each world fair.
The expo is also trying to address the critical issue of water use. “All rainfall within the main areas of the expo garden can be recycled for daily use,” said Mr. Wan, referring to installed devices on the pavilions that collect and recycle rainwater.
Collected rainwater from Sunshine Valley in Yanqing county in Beijing will also supply water for more than 30 public toilets installed at the site to serve approximately 8,000 visitors at any one time.
