The risk of investors targeted green technology
The United States most legendary venture capitalist John Dole sharp insight, in Google, Amazon and other companies to become well-known for its large investment before, so the accumulation of enormous wealth. Today, Dole will be known as attention turned to the emerging green technology industry.
Green technology (Greentech) that is clean technology, covering the water purification, air purification, nanotechnology, alternative fuels, can be recycled and renewable sources of energy and other related technologies dell latitude d510 battery,dell latitude d520 battery. Dole believes that green technologies like information technology and biotechnology have the same high returns, the 21st century will surely become an investment destination, and now it is time to increase investment in green technology for the best time. As Silicon Valley’s most prestigious venture capitalists, one of Dole’s investment in green technology to predict the risk of the investment community has aroused concern in the community.
U.S. National Venture Capital Association (NVCA) President Mark Heesen noted that Dole has a natural insight into industry trends, from KPCB, he managed the company’s investment plan, the green technology industry will usher in a new wave of investment.
U.S. green technology venture capital network to a report released recently shows that in North America in 2005 to invest in clean technology venture capital of more than 1.6 billion U.S. dollars the total amount of more than 35 percent growth in 2004. The fourth quarter of 2005 alone, investment in clean technology venture capital of 502 million U.S. dollars were as high as 2004 compared to the same period surged 60%. The report predicts that the next 3 years in North America the risk of investment in green technology is expected to double.
U.S. research firm Clean Pioneer released in March showed, such as bio-fuels, hydrogen fuel cells, solar and wind energy and other clean energy markets of the world’s total 40 billion U.S. dollars last year, as traditional energy prices rising, this figure is expected in 2015 before the year will increase by up to 3 times the 167 billion U.S. dollars.
However, the risk of investment in green technology is also very strong. Mark Hesse noted that in the past on renewable energy and other clean technology investment often ended in failure, a very important reason is lack of market demand. In addition, the energy market is almost oil, coal and natural gas companies the world, alternative energy companies to snatch market share would be tantamount to.
The pursuit of venture capital is high risk high return. With technological advances, more and more venture capital into the green technology industry, investment in clean technology projects have a lot of access to the higher returns. More important point is that the U.S. clean technology companies such as SunPower IPO success of venture capitalists have greatly increased the confidence that they look forward to Google, Amazon and other companies listed in glory after the dell latitude d600 battery,dell latitude d610 battery,dell latitude d620 battery recurrence of green technology industry.
Methanol as alternative fuel vehicles is feasible
Since the last century since the 80’s, methanol as a fuel research and development has always received much attention lately, the industrial application of synthetic and vehicle technology to make significant progress, it is now time to give the scientific concept of development evaluation. Dimethyl ether fuel, although the development of late, but the momentum of rapid, it should give a reasonable evaluation.
On the basis of the current level of research and application technologies, the methanol as an alternative fuel vehicle technology does not exist, the environment and security issues, the key is people’s awareness, government policies and effective management.
The toxicity of methanol fuel
Methanol fuel in addition, storage, transport and vehicle exhaust have produced a small amount of methanol vapor. Human exposure to methanol there are three main ways: breathing vapors, misuse of drink and skin absorption exposure. Therefore, the use of methanol as fuel must be carried out in strict accordance with the operating procedures to minimize the leakage of methyl alcohol to avoid direct access to the digestive system. Shanxi Province for more than a decade in M15 and M85-M100 methanol fuel dell latitude d800 battery model practice, the Secretary of the relevant personnel to take a medical examination showed that the track was not found with methanol caused by abnormal or occupational health cases. United States Institute of methanol toxicity of methanol fuel and the use of security has been very detailed assessment of the overall view that the use dell latitude d510 battery of methanol fuel in the fuel is safe.
Methanol fuel impact on the ecological environment
Methanol fuel as a clean alternative to diesel fuel and fuel cell vehicle future large-scale use of fuel, on the surrounding ecological environment has been that people are generally concerned about another problem. Methanol in the soil susceptible to biodegradation. And gasoline is hard to dissolve in water, not proliferation, in the difficult environment degradation, the occurrence of accumulated pollution. Comprehensive comparison, the methanol removal easier in the environment.
As a result of the use of coal gasification technology, coal pollutants such as sulfur, nitrogen, chlorine, mercury and other impurities can concentrate completely removed, thereby reducing the direct fuel pollution caused by coal, and the synthesis of almost no emission of pollutants, therefore, the production of methanol fuel is a clean coal technology, the smaller the pollution of the environment, especially in multi-generation technology, energy use and resource use has been further enhanced.
Methanol fuel vehicle cold-start
Methanol fuel vehicle cold-start difficulties, will lead to incomplete combustion of formaldehyde, methyl formate, such as hydrocarbon emissions, but the use of exhaust purification equipment to deal with easily. This regard, the course of many years of practice in Shanxi Province has made a reliable purification technology. Therefore, the large-scale use of methanol fuel vehicles, will not cause even more serious than the exhaust gas emission.
Corrosive methanol fuel cars
Methanol is a polar organic solvent, for certain rubber and plastic products prone to swelling, premature aging, and certain non-ferrous metals such as aluminum, copper has a corrosive effect, and therefore part of the automotive parts and components appropriate to deal with in order to dell latitude d520 battery,dell latitude d600 battery,dell latitude d610 battery methanol to increase the adaptability of the materials. Wharton Company in Shanxi Province for many years the practice has shown that there is no blended with low percentage of corrosion, as can the use of regular gasoline; Shanxi best practice shows that the new company, such as pure methanol fuel to the engine there is no significant corrosion, but some parts need to use Alcohol-resistant materials, such as the use of alloy materials, components, pumps, etc. Alcohol resistant.
Resources methanol fuel cars
The main use of domestic coal production of methanol. China’s coal resources, about 40% of high-sulfur, low quality coal, can not be used as steam coal direct combustion, gasification through desulfurization, can be used as raw material for synthesis of methanol fuel, the use of access to clean. In addition, biomass gasification methanol synthesis process further methanol fuel can become a renewable energy, both at home and abroad are paying attention to is the future synthesis of an important means of methanol fuel. Therefore, we believe that the full use of China’s relatively rich in coal resources, especially high-sulfur-rich low quality coal reserves, combined with coke oven gas and coal-bed methane resources, such as the large scale synthesis of methanol fuel to replace some of the oil resources. With the biomass gasification technology to improve and mature, from the preparation of methanol from biomass will gradually make up for the fossil fuel energy consumption of resources caused by vacancies, and ultimately become a fully renewable fuel.
Methanol fuel vehicle technology
China’s coal methanol as raw materials to produce dell latitude d620 battery,dell latitude d800 battery a mature and advanced technology not only has its own design, manufacturing and construction capacity, methanol production, the market competitiveness of products, has been involved in the global competition in the market. Domestic coal-scale methanol production from an annual output of 50,000 tons to 800,000 tons, the current planning of two million tons of annual production capacity of the project methanol production scale for the production of methanol fuel to provide a better flexibility, but the enterprise in order to improve the resources and energy efficiency, market competitiveness and influence, the new methanol projects tend to increase.
On coal-based dimethyl ether fuel
Dimethyl ether fuel with high cetane number (50 ~ 55), an ether fuel combustion for better results, and there is no low-temperature methanol and accelerate the start of the shortcomings of poor performance is an ideal substitute for diesel engine fuel. Studies have shown that DME as diesel fuel for vehicles with high efficiency and low pollution, it can be to achieve a smoke-free emission, and reduce noise and to reduce nitrogen oxide emissions. In addition, dimethyl ether and liquefied petroleum gas liquefied petroleum gas properties similar to liquefied petroleum gas is an ideal alternative fuel. Under the same conditions of temperature, dimethyl ether down the saturated vapor in the gas, its storage, transport and other security than the liquefied gas. However, dimethyl ether production technology is still two-step dehydration of methanol, higher production costs, one-step production of dimethyl ether are not yet ripe for industrial technology. Although DME fuel like cars dell latitude d810 battery, but car engines and the practical application of and should therefore pay special attention to, focus on the production of DME engine technology and applications.
