Solar System

There is water in the Cosmos? This fascinating question is object of discussion for a long time in the scientific community. At the moment it is known that the water molecule is concentrated, in the form of ice and of steam, in some privileged places, essentially in certain cold clouds of our galaxy. But the Solar System only contains important water concentrations and the Earth only has its liquid form. So that the Earth enjoys that privilege? From where comes the water and since it has formed? In this article recontruye its history, from its training in the surroundings of cold stars to his completes adventure in planets of the Solar System. Is it – in the form of steam or of ice – in the atmosphere of some stars, in molecular clouds, numerous ice satellites of the Solar System, in comets and planets of the Solar System. But what is exceptional, it is the water presence in liquid state: the Earth is the unique place at the moment known in which the water appears in this form.

From where the terrestrial water comes so indispensable for the life? So that it subsists, and so barely in addition, in liquid form? In order to include it the astronomers they have reconstructed the adventure of the water in the Cosmos that begins around certain cold stars and that lead, after the formation of the Solar System, to the water and the present ice in planets. The water can be formed of natural form in diverse regions of the Universe from its components – hydrogen H and oxygen 0. The hydrogen represents more of 70% of the visible mass of the universe. With regards oxygen, it constitutes around a 1%. But the presence of these atoms is not enough to make the existence possible of the water: it is necessary that concrete conditions favor the formation and the survival of their molecules.

Alternative Energy

68 Per cent of the electricity used in the United States is generated by burning fossil fuels are polluting. The rest is generated in hydroelectric and nuclear power plants, and only a tiny fraction comes from clean, renewable resources such as wind, sunlight, underground steam and biomass (organic matter that is converted into energy). Now things are changing and some States require power-generating companies that obtain a percentage of electricity from renewable resources, and other States are considering implementing similar requirements. very low frequency renewable energy makes it possible to save money for consumers. When consumers use renewable resources such as the Sun and wind, the cost of electricity generation is reduced largely to the wholesale and electricity accounts are diminished. The use of renewable energies enables the reduction of the emissions that are harmful and deteriorating environment, in different parts of the world there is awareness about the topic and they have begun to put into practice forms of power that are not harmful to the environment. It has these measures joins the initiative of the recycling of waste in cities from containers in which classified the different items to be recycled. Original author and source of the article

Solar Energy

Solar energy is the energy produced by the Sun and that is converted to useful human energy, either to heat something, or produce electricity (as its main applications). Each year the Sun throws 4 thousand times more energy than that you consume, so that their potential is virtually unlimited. Solar energy is currently one of most developed renewable energies and therefore used at this time. How do we convert solar energy into useful energy? Solar energy is used for two things primarily, although they are not the only ones, for things such as food or water, known as solar thermal, heating and to generate electricity, known as photovoltaic solar energy. The main devices used in solar thermal energy are water heaters and solar stoves. To generate electricity using solar cells, which are the soul of what is known as solar panels, which are responsible for transforming solar energy into power Electric. Solar energy applications are not limited to those mentioned here, but these two utilities are the most important. Other uses of solar energy are: drinkable water heaters solar drying evaporation distillation R efrigeracion as you can see the applications that can be given to energy solar is very wide, and every day are finding new technologies to be able to take advantage of it.
