Solar energy comes from the earth's outer universal bodies (mainly solar), most of the energy human need is directly or indirectly, from the sun. Rightly all kinds of plants, through photosynthesis, convert solar energy into chemical energy, storing the energy in plants body. Coal, oil, natural gas and other fossil fuel ware formed from the buried plants and animals under the ground after a long geological generation. These are, in essence, the fixed solar energy of those ancient creatures . In addition, hydropower, wind energy, are also transferred from the solar energy. The solar power system, the earth itself, reserves of energy which usually refers to the energy related with the interior earth heat energy and that relevant nuclear core source energy.
Recent years, the producting technology of sand making machine has not been the industrial secret, but it is the first time to apply solar energy in sand maker. As we all know, the sand machine is always exposured in the sunshine for the whole day, so it's not impossible to use the solar energy to charge its generator.
And what is related with the nuclear reactions is nuclear power. When the structure of the nucleus changes, it will release a large
