HC Chemical Network Hearing, the United Nations climate change conference on December 7 at the opening of the Danish capital of Copenhagen. At the meeting, experts will discuss the world Energy Waste, resource over-exploitation, water shortages, global climate change and forest degradation, and many other topics related to environmental protection.
The United States, "Fun Science" website carried an article on the 7th, out of 10 Environmental protection Technology. Some people already heard about, some are just beginning, and some are even listen to some "non-mainstream."
Concerned about energy The 10 largest environmental technology concern is energy development, including six in the top 5 technology.
"Carbon waste into Oil "Technology topped the list. The technology proposed, at the appropriate temperature and pressure, any carbon material, from animal organs to discarded tires, can be converted into oil.
Third hydrogen fuel technology. Hydrogen fuel cells generate electricity using hydrogen and oxygen mixture, only to produce water, known as the "pollution-free alternative to fossil fuels." Now scientists have successfully developed for laptops and other small electrical power supply of hydrogen fuel cells, some Car Manufacturers are actively developing hydrogen fuel cell vehicles.
"Light substation to" technical ranks fourth. Solar cells have already not a new thing, the scientists present research focus is how to further improve the utilization of sunlight.
Ranked fifth ocean thermal energy technologies. According to the U.S. Department of Energy statistics, the world's oceans every day because of solar radiation absorption of energy equivalent to 2500 billion barrels of oil, while the U.S. annual energy consumption is only about 75 million barrels of oil. The temperature difference between sea water at different depths can be used to generate electricity, but the technology is not yet mature, the efficiency is not high.
Sixth of the tidal power is the beginning of last century's "old concept." It uses the energy generated when tidal water driven generator, but the problem is intractable, and sometimes too small to generate enough tidal energy.
Pollution control Addition to energy development, the reduced emissions are also 10 key environmental technology issues.
Ranked seventh in the "sky garden" plan, the roof of the building in the city built garden plants to absorb heat and carbon dioxide, oxygen, and can be buildings cool in summer, reducing air conditioning use, which will ultimately help to alleviate the urban "heat island effect."
Biodegradation Technology ranks eighth. The so-called "biodegradable" refers to the use of plant or microbial decomposition of pollutants and toxic substances. Typical examples include the use of microorganisms to eliminate nitrate pollution of water and the use of certain plants to absorb soil arsenic compounds.
Gas deep technical ninth. It was suggested that carbon dioxide can be separated from other pollutants, into the abandoned oil wells, reservoirs or undersea salt. While this approach sounds reasonable, but scientists have long-term effects and costs of their questioning.
Effective use of 10 large green technology not only attach importance to "open source", but also pay attention to "saving."
Desalination technology second. This technology is the removal of salt and minerals in seawater, to be translated into drinkable fresh water. United Nations statistics show that by mid-century, water shortages will affect billions of the world's population lives. Desalination technology can solve some parts of the shortage of water resources dilemma. But the technology was cost and high energy consumption. Scientists are studying how to make water evaporate with cheap fuel to improve efficiency.
Ranked 10th of the paperless technology proposed, with a reusable " Electronic Paper "instead of traditional paper. Is actually a piece of electronic paper display, which arranged the live array of microcapsules, each microcapsule by imposing voltage control at both ends of its body appear as black or white, it will be e-paper show a pattern. whether the newspaper or news stories can be in the same piece of electronic paper display, to avoid waste of paper.
