1、Solar powerSolar energy for several billions of years, solar energy is the solar radiation energy to the Earth. Solar energy can be directly or indirectly converted to other forms of energy, such as heat and electricity. The main disadvantage (question, or problem to be overcome) of solar energy are
2、: (1) intermittent mode Get the Earths surface, (2) a large area to gather in a large container.With economic development, social progress, peoples energy to ever-increasing demands, find new sources of energy has become an urgent issue facing humanity. Existing energy major has three kinds, namely,
3、 thermal power, hydropower and nuclear power.Water and electricity to a large number of submerged land, that could lead to ecological destruction and the collapse of large reservoirs once the collapse, the consequences would be disastrous. In addition, a countrys water resources is also limited, but
4、 also by the impact of the season. Nuclear power under normal circumstances is clean, but unlikely event of a nuclear leak, the consequences are terrible same. The former Soviet Union, the Chernobyl nuclear power plant accident, has nine million people have been varying degrees of damage, and this i
5、mpact has not been terminated. These are compelling people to go looking for new energy. New energy to simultaneously satisfy two conditions: First, not depletion of rich; II are safe, clean, not a threat to humans and damage the environment. Currently found in the main, two new energy, solar energy
6、 first, and second, the fuel cell. In addition, wind power could also be regarded as supporting the new energy. One of the most ideal form of new energy sources are able to Dayang. Solar power generation are the best new energy Radiation in the Earths solar energy is very strong, about 40 minutes ex
7、posure in the Earths solar energy, would be sufficient for the global human energy consumption for one year. It can be said that solar energy is truly inexhaustible source of energy. And solar power is absolutely clean, no pollution. Solar power generation are therefore known as the ideal source of
8、energy. Obtained from solar power, sun through photovoltaic cells transform to achieve. It with other power generation principle of the past, entirely different, with the following characteristics: no danger of depletion; absolutely clean (free); not subject to geographical distribution of the resou
9、rces constraints; nearest Department in electricity generation; energy, high-quality; users emotionally receptive; access to energy to spend a short time. Inadequacies are: exposure energy distribution density, which was to occupy a huge area; energy obtained with the four seasons, day and night and
10、 the clear one, such as meteorological conditions. Overall, however, as a new energy, solar energy has great advantages, so the importance attached by countries in the world. Solar power applications Although solar power by day and night, barometer, seasonal impact, but can be dispersed manner, so i
11、t is suitable for families to carry out sub-exciton generation, but also to connect to the electricity network, making the family rich in the power may be sold to power companies, can be less than when bought from the power companies. Implementation of this technology is not difficult to resolve, th
12、e key is to have the appropriate legal protection. Now the United States, Japan and other developed countries have enacted appropriate legislation, to ensure the conduct of domestic solar power generation benefits to encourage families to carry out solar power generation. The prospects for solar pow
13、er generationSolar power generation has more exciting plans. First, Japan plans to Genesis. Ready use of the ground area of desert and ocean to generate electricity, and through the superconducting cable will be the worlds solar power stations into a unified power grid to the global supply. It is es
14、timated that by 2000, 2050, 2100, even if the whole solar power with global energy supply, but also as an area of 651,100 square km, 1.8679 million square kilometers, 8.2919 million square kilometers. 8.2919 million square kilometers accounted for only 2.3 percent of all marine area or all of the de
15、sert 51.4%, and even the Sahara desert is 91.5%. Therefore this program are possible. Another generation programs are in heaven. As early as 1980, NASA and the Department of Energy has proposed building a solar power station in space the idea of ready-synchronous orbit in place a long 10 kilometers
16、wide and 5 kilometers of large flat-panel, the top covered with solar cells so as to provide five million kilowatts of electricity. However, this needs to be addressed to the terrestrial wireless transmission problem. Have been proposed by microwave beam, laser beam, such as a variety of programs. Model plane with the current implementation has a short-range, short-term, low-power microwave wireless power transmission, but ther
