The reason why the development of nuclear power plants so fast because it has many advantages.

First, it is an effective alternative energy sources. Small size of nuclear fuel high energy, nuclear chemistry is greater than a few hundred times. 1 kg of uranium -235 release energy equivalent to 2700 tons of standard coal, the energy released. A one million kilowatts of large-scale thermal power plants, coal 3 million per year? 4 million tons, transport the coal trains need to 2760, equivalent to eight trains a day, but also removed (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…)

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…)

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…)
