With nano-technology to solve the world’s energy problem
In 2000, the world’s energy consumption is about 14115 trillion watts hp pavilion ze2000 battery, hp presario m2000 battery, hp presario v2000 battery, the 85 percent of which comes from fossil fuels or nuclear energy. Primary energy of one of the most important consumer is the power sector. By 2020, total energy consumption is expected to grow by 20 percent, in the absence of effective measures, carbon dioxide emissions will increase by 14%. According to the “Kyoto Protocol”, the EU commitment from 2008 to 2012 carbon dioxide emissions during the 90 years than 8 percent lower, to that end , the share of renewable energy rose to 6 percent from 12 percent and improve energy efficiency. In order to achieve these goals, the solution includes not only technical means, including changes in energy transmission and utilization of the potential method. Therefore, the energy sector to promote research and technology development is the key step.
In order to develop cleaner, cheaper and effective technology, the need for interdisciplinary efforts, including various technical fields such as energy, chemical engineering, biotechnology, sensors, information technology, material science, materials engineering and so on. In these areas, nanotechnology and nano-materials are considered potential of energy systems will have a significant impact.
Nanotechnology involves single atoms, molecules or clusters of processing or the formation of self-assembled structure, to create a structure with a low size of the new features or different characteristics of the materials and devices. And the energy sector is most closely related to the above-mentioned particle size. This may be of spherical particles, cylindrical nanotubes or nano-porous materials. Nanotechnology is the most interesting nano-sized particles with completely different from the macro-world properties of the same material.
Related to the role of nano-technology
Compared with the bulk materials, nano-particles and energy the most relevant role in the application of a large number presario v5000 battery, compaq presario v4000 battery
of exposed atoms on the surface. As the huge surface area with less material can result in higher response rate, which is a better catalyst for the production (leading to higher response rates, lower processing temperature, to reduce emissions or need a few raw materials), improved combustion processes (higher efficiency, lower processing temperatures) or to increase the rate of light absorption is useful. The surface effect also applies to energy storage applications (such as: hydrogen storage electrode or lithium batteries) or energy conversion (fuel-cell electrode). We can use the size of absorbent nanoparticles to regulate the spectral absorption. Take advantage of this effect can increase the absorption of solar cells in order to improve efficiency. The same size with conventional materials, the mechanical properties of such materials in the nano-region can be changed dramatically. For example: nanotube strength steel than the same size is much higher. In composite materials, which can produce lighter materials for automobiles or aircraft, while reducing energy consumption.
The potential applications of energy conversion
There are nano-layer or nanorod solar cells can be greatly increased power output of the sun. Nano-structured materials, or nano-components can be used in the future or emerging technologies in energy production, including solar photovoltaic cells and hydrogen energy conversion. Nanotechnology will help to promote the development of fuel cells has brought about a more effective and more cost-effective electrode and electrolytic material. Aerogels is a kind of transparent nano-porous insulation materials, have been developed for the solar collector cover materials. Nano - structured materials in thermoelectric devices demonstrated its potential for future applications. In addition, nano-biotechnology research to increase knowledge, so that the success of bio-energy has been the construction of subsystems.
