Geothermal energy in China

Geothermal energy in China
Перевод на русский язык...
China is actively working on issues of development of geothermal electricity by the way. Previously, next to a small Chinese town Guncha, which is located in the northwestern part of China in the thickness of the earth close to the surface discovered large reserves of hot water and hot rocks at depths of up to 230 meters. Previously in China, looking for places where it would be possible to dry to take heat of the Earth, but all attempts until the last day were fruitless. Qinghai province is the only place in mainland China where you can take heat from the hot rocks direct way. The place itself is quite suitable for large-scale development and use.
Dry heat generation of the earth is in the selection is not injected into the cavity in the earth is strata of the water, a selection of heat using special core, which deepened in the hot rocks at the depth of up to 10,000 meters deeper If there are such species, the heat from the depths below than 10 km already not appropriate. The rocks that are used to heat should have a temperature below 150 degrees. Usually the temperature is in the range between 150 hail and 650 degrees on the upper side.
The use of such energy-intensive layers allows you to generate electricity in an environmentally friendly way.
Earlier, such projects are implemented in areas where the surface of the hot springs or anywhere in the cavity of the Earth there is hot water. Water was pumped under pressure into one place, and superheated steam averted in the turbine hall in another place. So he worked earlier this thermal energy. The first thermal power plant appeared thanks to the American scientist back in the 70-ies of the last century.
The new technology is called ?hot dry rock?, not Chinese invented, although you will! The deeper you fall, the higher the temperature of the reservoir. There is a certain law, every 100 meters down add 3 C for temperature. The first thermal power plant was introduced in America. In an underground cavern at a depth of 5 km drilled two boreholes spaced from one another. In one fetch water, but from a different take superheated steam. As in China will be implemented all the time will show.

In Chinese Lu Xiaodong was struck by lightning
In southern China rainstorms and lightning is a common phenomenon, lightning many and they hit so often that the wonder that is shown in the video below is not necessary. The video shows a reporter with a Chinese TV channel that tells about the bad weather in the country and suddenly it gets a bolt of lightning....
In Harbin in the cold water, swam a Chinese walrus
Although the air temperature at the time of the swim was about -10 degrees, this does not affect the desire of the Chinese walruses to swim a set distance in the icy water. Walrus from all of greater China gathered at the festival for lovers of cold baths, in the city of Harbin, came all who wanted to compete in speed swimming in the icy water of the local river....

Line speediest train is started In China

 Line speediest train is started In China
the December 26 in China have started in deal the too long railway pathway on which will be able to move the speed train. The Route is listed as G502 and has connected two high developed in industrial attitude of the city Guanichzhou and Pekin. The Distance between these two cities 2 298 km. The Train преодолеет this distance on velocities in 300 km whole for 8 hours. Usual composition spent on the whole way day, but also that if average velocity on route was 100 km. China constantly modernizes the railway and are chosen area with big passenger turn just. Basically this industrial centres. On given time in China already marketed too long pathway of the speed message.
Today in Ambience composition number 801 successfully went to the first way from station Peking aside Guanichzhou. Departure time 9 mornings. Simultaneously on one and the same route go three trains with difference at time. One came out of Pekin, the second came out of Hanchzhou, but the third came out of city Siani.
After started the new railway general extent speed pathways in China reached 9.3 thous. km, but after pair of the years on calculation she already will as minimum in two times long.
