The American "Fun Science" website published an article on the 7th, listing 10 environmental technologies, among which Some people have already heard, some just started, and some sounded even some "non-mainstream". The top ten environmental skills pay most attention on energy developing. It includes 5 skills in the first 6.What is Most Enchanting Choice for Professors? ugg classic short !
The [Carbon Garbage Change into Oil" technology is NO.1 in the list. This technology pointed out that any carbon from the pluck to the old tire can be transformed into the petroleum.The Most In Season tiffany and co Show up, Go to Have a Look!
The hydrogen fuel technology was NO.3. Its cell used hydrogen and oxygen blend to generate electricity and only result to water, called the [cleaned substitute for fossil fuels". Till now, scientists have successfully invented the hydrogen fuel battery which can provide electric for small machines such as the laptop. Some car manufactors are making efforts on the invention of hydrogen fuel battery car.Valentine's Day Gift Ideas for Women
"Transformation from light to electrical energy" ranked fourth. Solar cells is no longer a new thing, scientists focuse on how to further improve the utilization of sunlight in current research.
Ocean Thermal Energy Technology ranked fifth. According to the U.S. Department of Energy statistics, the world's oceans absorbed the energy due to solar radiation equivalent to 2500 billion barrels of oil every day, while the U.S. annual consumption of energy is equivalent to 75 billion barrels of oil. Besides, the temperature difference between different depths in the sea could be used to generate electricity; however, this technology is neither mature nor effective at present.
The sixth on the list is tide generation which has been raised early last century. It uses the energy produced by tidal to drive the generator for electric. The present problem is that it is hard to control. Sometimes the tidal is too small to produce enough energy.
Apart from energy development, how to reduce pollutant discharge is also the problem the ten technologies focus on settling. The plan of the seventh place "air garden" is about the building of gardens and growing plants of top of city artitectures to absorb heat and carbon hydron and release the oxygen. In addition, the plan can also reduce temperature of storied buildings and the use of air-conditioners in the summer, finally it can be helpful to relieve cities` [hot island effect".
Biodegradable technology ranks eighth. The so-called "biodegradable" refers to the use of plant or micro-organisms for breaking down pollutants and toxic substances. The typical example includes the elimination of nitrate pollutions in water by microcreatures and the absorbation of containing arsenic agents in soil by some plants..
The technique of deep burying of exhaust was on the ninth. Someone said the carbon dioxide could be separated from other pollution, inject it into the old oil well, reservoir with high salinity, even in the ocean. Although this method is reasonable, scientists are dubitable on the long-term effects and cost.
The ten environmental protection techniques attached importance to not only `increasing income` but also `reducing expenditure`. The technology of desalination of sea water ranks second, which means removing the salt and minerals in seawater, and then seawater can be turned into fresh water. UN statistics show that water shortage will influence the world population of billions of life by the middle of this century. Seawater desalination technology can solve water nervous of part of region in a certain extent. However, this technology has two technical problems higher cost and power consumption. Scientists now are studying on how to use cheap fuel to make water evaporation in order to improve efficiency.
The tenth is the application of the paperless technique. Using the `electronic paper` repeatedly to replace the conventional paper. Regardless newspapers or novels, they could be display in the same electronic paper, avoiding the waste of paper.
