So that carbon-zinc batteries withdraw from the market to fill the “ecological compensation” dead ends
Recently, the “ecological compensation” term for many Digital Camcorder Battery experts and scholars as well as the work of the government in the key word. The so-called eco-compensation refers to the eco-service beneficiaries of ecosystem services providers given financial compensation. The establishment of ecological compensation mechanism means that environments from the “priceless” to “has a price.” But in fact, a major ecological projects (such as rivers, forests, etc.) can use the “ecological compensation” approach to achieve effective control, but another important source of environmental pollution, it is usually not attracted much attention of the domestic pollution, such as discarded batteries, Waste ink cartridges, disposable plastic bags. It is understood that people’s lives are often used in carbon-zinc batteries (commonly known as ordinary zinc-manganese batteries, high-power battery, high capacity batteries, etc.) because of higher levels of mercury, mixed with garbage after use with the landfill, or throw the battery in the The mercury will infiltrate the soil, polluting groundwater, and then into the fish, crops, crimes against humanity living environment and health. It is understood that a battery-generated hazardous substances can contaminate 600,000 liters of water, equivalent to a person’s life, the amount of drinking water: a rot in the ground in a square on the 1st battery can be swallowed
Meters of land, and can cause permanent pollution. Therefore, how they deal with scientific and rational environmental protection is the government and experts have been troubled by problems.
Two year period, the local, national over NPC Digital Camera Battery deputies and CPPCC National Committee members have carried out this proposal. Wang Ping, the CPPCC members that the key to solve the battery problem of pollution is the “inter-departmental joint enforcement, comprehensive restrictions on the production and sale of mercury-containing carbon-zinc batteries.” Meanwhile, the need to “strengthen the environmental publicity and increase the battery environmental propaganda.” In addition to Wang Ping, the NPC deputies from the Shantou Lin source of used batteries has also put forward their own proposals. In the earlier parts of the two sessions, Shanghai, Zhejiang and other places where representatives of the used batteries made their views.
Alkaline manganese batteries (commonly known as alkaline batteries), its mercury content less than 0.0001% weight of the cell, with the mercury inside the soil is very close, almost without causing pollution of the environment, no recovery, you can live with the garbage. This also makes the development trend of global battery. 1996 United States federal law enacted in “mercury-containing batteries and rechargeable battery management approach” explicitly provides that prohibit the sale of mercury-containing zinc-manganese batteries; the European Union in March 1991 and 1998 has issued an order that the sale of mercury in the EU ban 0.0005% greater than the quality of the Casio Battery cell.
In China is also on the mercury-free batteries was well established. In December 1997, China Light Industry Association, the National Environmental Protection Bureau jointly issued by nine ministries and commissions “on the restriction of the provisions of mercury batteries,” request “from January 1, 2002 onwards, to prohibit distribution in the domestic market of Class mercury content greater than 0.025% weight of the battery cell. “Chinese Battery Association has also announced the end of October 2006 Nanfu mercury-free batteries, etc. 11″ green alkaline manganese battery “list. However, the practical implementation of the provisions of the obstacles they face excessive mercury is still a large proportion of carbon. According to statistics, as of the end of 2006, the domestic proportion of mercury-free alkaline batteries is only 20% did not achieve the “Tenth Five-Year Plan” in the 30% target. Experts said, so that carbon-zinc batteries delisting from the source to control the flow of carbon-zinc batteries, the battery will help to solve environmental issues, thus contributing to the improvement of ecological environment in Casio NP-100 China as a whole.
Alone a solar panel will be able to cross the Atlantic!
May 8, the whole solar-powered catamaran vessel “Sun 21″ are approaching New York, Manhattan. “The Sun 21″ on October 16, 2006 set sail from the pier in Basel, Switzerland to the United States, New York, began the first trans-Atlantic journey. The ship 12 tons of weight, 14-meter-long ship is a top-60 Casio NP-20 square meters of solar panels for the hull of the two engines to provide energy.
Dross to get essence of new filtering technology to enhance the efficiency of fuel cells
Taiwan’s scientists have recently invented a new method can greatly improve the efficiency of fuel cells.
It is reported that Taiwan’s National Tsing Hua University, a research team has developed a new filtering technology, you can clear out methanol fuel cell (DMFC) in some of the by-products, thereby enhancing its operational efficiency, while eliminating the extra power Casio NP-30, Casio NP-40. As the catalytic reaction of methanol does not require complicated, dangerous to store than hydrogen easier, and therefore very suitable for DMFC for portable electronic devices provide energy, but due to the oxidation of fuel will produce carbon dioxide and other byproducts of power generation efficiency of methanol has been not very ideal.
National Tsing Hua University in Taiwan, researchers have produced such a filter is expected to solve the problem. This passive filter is equipped with about 100 50-micron-sized holes can be carbon dioxide and other waste discharged into the atmosphere, but also covered by a layer of water-resistant Teflon (PTFE), can take away moisture at the same time does not affect the DMFC valuable energy Casio NP-L7 output.
