    Solar energy in world

    A long time, people have been working hard on the use of solar energy. Received by our planet of the solar energy, only the surface of the Sun issued all about energy, the energy equivalent of the world’s total energy requirements of the 3-4 million-fold, is inexhaustible, and the non – exhaust. Secondly, the space is not divided into days and nights and seasons, no clouds and shadows, very stable radiation energy in.

    Thus generating system than the ground relatively simple, but in the absence of weight, high vacuum environment of the universe, the strength of equipment components is not too high demands. Moreover, solar energy and oil, coal and other fossil fuels, would not lead to the “greenhouse effect” and global climate change, will not cause environmental pollution. For this reason, the use of solar energy (laptop battery) are of great importance in many countries, we are in a race to develop new technologies and photoelectric photoelectric new materials to expand the utilization of solar energy applications.

    Especially in the past 10 years, in increasing oil production to the bottom and the deteriorating ecological environment of these two crises together with the attack, we are looking forward to more and more “solar age” to come. From power generation, heating, water supply to a wide range of solar power plants, and their use is very extensive, and in some areas, the use of solar energy has entered the practical stage.

    From 1974 to 1997, the United States and Japan and other developed countries silicon photovoltaic power generation costs by an order of magnitude: from 50 U.S. dollars per watt down to 5 U.S. dollars latitude D620 battery. Since then most of the world experts believe that solar power station to station with the traditional (mainly the power plant) compared with the competitiveness of the economy, there is still a long way to go in the same – to reduce the cost of re-do an order of magnitude.

    At present, the United States and other countries make use of solar pond built by the project a lot of power. The banks in the Dead Sea in 1979 to build a 7000 square meters of the experimental solar pond for a heat generating 150 kilowatts. The United States plans to 8.3 percent of its Salt Lake area (about 8000 square kilometers) solar pond built for the 600-megawatt generating units of heating.

    In June this year, Armenia Radio Physics and dell experts announced that the mountain in the country has begun the construction of its “The first experimental prototype” solar power plant industries. The turbines used in power stations is not new, but life has expired and removed from the helicopter to the turbine installed capacity of only 100 kilowatts, but the electricity cost of 0.5 cents / kilowatt-hour, efficiency as high as 40% -50 %.

    Russian scholars in the study of solar pond has also made remarkable progress. A company to develop solar energy and water jet propulsion thrusters cool project with a combination of solar pond, solar pond to the tank with ice and other facilities designed for the new solar pond farmers. According to this design, a 6-8 person households to build a solar pond of 70 square meters, 100 square meters will be able to meet their housing needs of the whole year of electricity.
