In the oil, coal and other traditional energy supplies become more and more critical today, how to look for new clean and renewable energy, become the focus of many research and development. Germany scientists use of new technology, the Earth and the sky to energy, we use for reference.
Magic set heat pipe for the solar power generation
In Spain, Andalucía, local sunshine and Germany's technology together, the results can be for Europe's energy supply has brought a revolution.
From La Kara Euler castle walls looking out on, in front of is extremely beautiful landscape. The distant horizon stands snow-covered peaks of the Sierra Nevada Mountains, ancient castle of stretch for many kilometres of the fields and Plains. But more importantly, there is no other place to offer a better vision, to observe a technical masterpiece of Super. The masterpiece is not just in Spain, in other places here is unparalleled: Brown and green shade cutting scenes, Sun 6-metre-high parabolic mirror group shining, parabolic mirror head of hundreds of metres, covers a area up to 5.1 million square meters of land, more than 70 football field. The mirror group in the world's largest solar power station to collect energy.
In June 2006, people started construction in Spain Granada region known as the "No. 1" anda Sol solar power stations. Latest by the end of this year, the station can offer 50 megawatts of power to meet the 20 million people's demand for electricity, the power completely is taken from the Sun. "Anda Sol 2" construction work is already underway for a year, "anda Thor 3," has finished the planning. Explore this clean power plant technology is the "solar Millennium AG", which is a company from Germany in the southern part of the small business, with headquarters in Erlangen, it not only design and develop a "anda Sol No. 1", also with Spain partners built it.
Parabolic trough solar power special mirror is its technology. And solar battery, the power station is not the direct conversion of sunlight into electrical energy. Mirror to over 98% of accuracy will shine in the Sun, reflectivity to a through the collectors focus line receiver tubes (also known as receiver). Absorber tube is an agglomeration of sunlight heated to approximately 400 degrees of heat liquids. The liquid heat transfer of the Sun to heat exchanger, where steam driven turbine power generation, which in turn.
Absorption of thermal energy storage material or secret
This equipment from Germany or even in the night functioning: after the sun goes down, is located in the collector area central heat storage will release the needed energy. Special high-tech is the receiver technology, it consists of a metal tube and a glass casing, between the two is the vacuum tube to ensure that the metal pipe insulation to minimize heat loss. Because you want to make as much of the Sun, no reflection through the glass tube light into metal pipe and be absorbed, so need very special material, the composition of these materials or a secret. In the world only two enterprises can create such a receiver, one is from Germany and us Cairns of glass and optical manufacturer short (Schott) company. Spain's solar power is the use of its technology.
This high efficiency power generation is the sea-· Gladden prediction was one of the reasons. The solar Millennium company's Technical Director, see the parabolic trough mirrors the tremendous opportunity for solar power, "only in Spain, the potential of their generation reached 10000 ~ 15000 MW, equivalent to 10-15, the traditional large power station. "Germany Aerospace Center research also confirmed that these figures. 15 years later, this kind of power from North Africa and southern Europe provide clean energy to the world. Solar Millennium company had planned to build solar hot air: power station. Erlanger's firm intention to desert in the construction of a thousand meters high chimneys and several kilometres of glass roof. The Windows of the air is heated by sunlight to form, updraft chimney at the bottom of the turbine power generation. By that time, there is no need to climb the high Castle, to the now jingxian parabolic trough solar power mirror surface.
Geothermal power generation also
The depths of the Earth have an endless supply of energy potential — are stored in the formation of thermal energy. From Germany's magical drilling technology make this heat energy has been economically practical.
Down from the highway, in a few kilometers of blue flags "GFZ" small sharp turn to the right at the sign, and then close to 400 meters of uneven field track, after a stone quarry, then you will see treetops above the rig's White Spire. 19 February this year, from the whole Europe 100 geological workers, technicians and energy experts, go down this route from Munich to this called Donne HAL (Durrnhaar) little place. They want to share experiences and learn about "the future of geothermal technology". Rig name InnovaRig written in the fuselage, occupies a large baitie fuselage. The machine is 52 metres high, has about 2 700 horsepower, drilling depth up to 5000 meters. Switch on the machine is neither to mining oil, nor extraction of natural gas, but rather to explore an entirely special treasure – hot water. 2008 will build on the hot water promote a 5 MW power station operation, at the same time get power and thermal energy. The plant can operate 24 hours a day, with or without wind or sunshine. Located in Donne Har's drilling equipment is unmatched
。 Potsdam Center for Earth and Germany tunnel drilling manufacturer herrenknecht Nye Richter company, together with the development of this platform is full of innovative ideas and deep hole drilling machine. In February, sunny day, the guests surrounded to Bavaria, craned his neck up rig, but they do not hear any sound or smell no taste. Precisely this is unparalleled in deep hole drilling machine. And the company with the same CEO Martin · herrenknecht Naidu, Richter said: "the device is running without waste emissions, no noise, can be used in residential areas. "This is for geothermal resources very important advantage. Because from the economy, it can be used only in those places where you need it directly. The Assembly can be fully automatic drilling rig, according to the different needs of different drilling technology. This "miracle of technology" (herrenknecht Nye Richter company statement) daily for up to 100 meters of drilling. Visit of the professional groups on this very recognition, constantly doing records. It is said that, before the summer, there will be 150 per second up to 140 degrees hot water from 4400 m deep underground pumped to the surface.Company President Martin · herrenknecht Naidu, Richter said: "when we have to drill into the hot water layer, put away 6 meters of drilling rig to drill the second hole. "Geothermal resources for the acquisition, always to drill two holes: hot water is pumped from a hole, its thermal energy be used for the production of energy, cooling of water through the second hole and then sent back to hot rock. Before that, to achieve this loop cost very expensive because you want to remove and rebuild the rig. But removable InnovaRig rig, let this process costs significantly reduced, and thus have the possibility of using geothermal resources.
At present, worldwide installed to provide electrical energy power station, which is equivalent to the capacity of 7 reactors. But geothermal development is still lagging far behind the other renewable energy sources. In Germany, "geothermal" in environment-friendly energy share of only 1% (2006). But from the end of 2007, the first ground power station started non-polluting emissions for 6000 families of power supply for about 300 households heating. Germany's Federal Ministry of the environment, there are about 150 seat and power station is planned. "We're in Germany to promote the application of geothermal energy. "InnovaRig developer herrenknecht Naidu, Richter said.
