HEFEI (China): A full superconducting experimental Tokamak fusion device, which aims to generate infinite, clean nuclear-fusion-based energy, will be built in March or April in China. Experiments with the device will start in July or August. If the experiments prove successful, China will become the first country to use such a device, named ``artificial sun,'' experts here said. The project, dubbed EAST (experimental advanced superconducting Tokamak), is being undertaken by the Hefei-based Institute of Plasma Physics under the Chinese Academy of Sciences. It requires an investment of nearly 300 million yuan ($37 millions), only one fifteenth to one twentieth the cost of similar devices being developed in the other parts of the world. The programme, still in its initial stages, involves Russia, Japan, the U.S., the European Union, China and the Republic of Korea. Scientists believe that deuterium can be extracted from the sea and an enormous amount of energy can be obtained from a deuterium-tritium fusion reaction under huge temperatures of 100 million degrees Celsius. After nuclear fusion, the deuterium extracted from one litre of sea water will produce energy equivalent to 300 litres of gasoline. - Xinhua
