A minimum speed of 4,000 kilometers, less energy consumption airliner 1 / 10, noise and air pollution and accident rates close to zero, a new type of transport - Evacuated Tube maglev train is very obvious - Evacuated Tube train, will Beijing and Washington into a two-hour traffic circle, with several hours to complete trip around the world has become a goal of scientists in recent efforts, and China in this study have been walking in the world.
The new maglev fear the environmental impact
Reporter from the relevant department, December 29, 2004, a has eight "houses" (Chinese Academy of Sciences, Chinese Academy of Engineering) Fellows, several national experts held a seminar attended. Involved in a number of academic authority is the main topic of the meeting - Evacuated Tube high-speed traffic. In short, building a pipeline cut off the outside air, the tube for the vacuum pumping after the operation in which the maglev train and other means of transport, the absence of air friction and obstruction, the train speed is staggering, can greatly reduce the Earth's surface space between the barrier anywhere. Pipeline because it is sealed, so you can bad weather in the seabed and run without any impact area.
Who are also "houses" Academicians Academician at the meeting that China should be targeting in the development of 600-1000 km per hour, high-speed ground transportation, four phases ,2020-2030 The annual operations.
Academician Zuoxiu although did not participate in the meeting, but he submitted to the Assembly his views in writing. In his view, the R & D high-speed magnetic levitation train, in the vacuum does not exist in principle the issue of difficulty.
Experts Yaoping in an interview that China is the fastest progress in the countries studied.
Theoretical maximum speed of 20,000 km
Reporter noted, first introduced the concept of magnetic levitation Evacuated Tube China, is a graduate of Southwest Jiaotong University of Yaoping, successful applicants in 2007, the National Natural Science Foundation project "High Speed Maglev Transport Evacuated Tube basic research," he began efforts to promote the "transport revolution" into reality.
ZHANG Yao-ping, said, first proposed the concept of vacuum Road Maglev transport, is the U.S. Rand Corporation and the Massachusetts Institute of consulting experts.
In 2001, after efforts to Yaoping acquired an academic, and government support in China, He said that the technology required for this project is mature. "The experts proposed by 600-1000 km per hour speed, is a conservative external diameter, virtually all researchers in the beginning of this mode of transport in the conventional speed of 4,000 kilometers per hour orientation, which is 6,500 kilometers per hour a medium-term goal. Recently I and a scholar and graduate student forum, they suggested that the theory of vacuum Road maglev train speed close to the first cosmic speed limit: You can achieve the speed of 20,000 kilometers per hour. "
ZHANG Yao-ping that the current research projects only need is to co-ordinate the national level from the first test line construction. Text / map, according to Shanghai Morning Post
