Solar power is the use of solar collector solar radiation into heat, then steam turbine generator to generate electricity. Conventional thermal power generation with the main differences are: Power source is not coal or oil, but solar radiation, with the collector and the absorber to replace the boiler.

The world’s first solar power station solar power achieved is about solar power stations in France Oder, its power output is only 64 kilowatts, but for the later study and design of solar energy power station foundation. Italy, Sicily and 1,000 kW solar thermal power tower is the world’s first (more…)

Solar house is the use of solar heating and cooling of housing construction.

Living in cold regions, such as the North and Northeast China’s live, when the room temperature down to 16 degrees below, people can feel uncomfortable; dropped below 10 degrees, hands and feet are not flexible. Therefore, the north building heating is indispensable housing construction project. Living in tropical areas, such as Hainan in China, and even Chongqing, Wuhan, Nanjing, live, when the room temperature (more…)

Idea of space scientists, there are two solar power program.

1. Build solar power satellites, the satellite with solar power;

2. The moon as a base, build solar power stations. The basic idea of these two programs are similar in outer space using solar power on Earth, in order to avoid Earth’s climate, nor even the difference between day and night, 24 hours a day to generate electricity. Then microwave and laser power transmission to the earth, the earth with the receiver, then the electric power for thousands of families into use. (more…)

Red sun, nurtured with great light and heat all life on Earth, but also to bring the unlimited human warmth. The growth of organisms on Earth and breeding, the climate of the formation and evolution of the global water cycle to have enormous energy and is closely related to the sun. The use of energy from the Earth perspective, solar energy is the most fundamental source of energy. (more…)

Ocean Tide, no matter where you are, always manifested in two ways. On the one hand is the height of the sea changes occurring continuously, that is perpendicular to the direction of water movement on the rise and fall, when the high and low sea surface so that water has potential energy. In addition, the surging tide, emptying from that water movement to the horizontal direction, the flow of water has generated (more…)

On the salinity difference can be used, now is in the principle of research and experimental stage, with the use of other ocean energy compared to its relatively late development, maturity is lower but very potent. Salinity difference can use the main form is still converted into electrical energy to use. (more…)

People know that when gas (air) or liquid (water, ammonia solution, sodium thiocyanate, etc.) is compressed, it will release heat. On the contrary, when the gas or liquid expands to absorb heat, this is called compressed gas or liquid exothermic, endothermic expansion principle. Endothermic expansion of people to use the principle of material to achieve the purpose of cooling. (more…)

At present, solar stills and more used in the desalination area. We know the total amount of water on Earth although many have 1.5X1018 cubic meters, of which 97.3% is brackish water, fresh water in the remaining 27%, 2% of ice, snow and ice distribution in the polar zone and other iceberg, only 0.7% of fresh water located in rivers, lakes, for people drinking and irrigation purposes, it is not enough. In addition, with the (more…)
