Solar thermal energy. More news from thermal energy on concentrated solar power (CSP).
because of the thousands of millions of dollars involved and the tens of thousands of households served with electricity, from a project. United States first and the world's largest project CSP is ending near Tonapah in Eastern Nevada. Technically, the thermal energy-efficient system generates electricity with large arrays of mirrors (planes, satellite or depressions) that they track and reflect the sunlight in a solar tower that heats the liquid above 1000 degrees F, creating steam that spins a generator, in turn, the creation of electricity. Crescent Dunes SolarReserve project 10,000 mirrors has the ability to generate 110 megawatts and will serve 75,000 homes. And because a corresponding molten salt storage system, you can send electricity 24/7. Another example is the company BrightSource Energy (AC) and here is a video of the Department of energy on the technology:Means higher temperatures forms of thermal energy creation, well below 1000 grados-son best suited to heat the water and are not efficient for converting heat into electricity. Iterations of this technology has existed since thousands of years (Roman baths of Ephesus, Turkey). Today's applications do not have to do with large tracts of land from the CSP systems use arrays, but rather in situ, used flat panel solar heat collectors. Applications include the direct heating of the spaces of residential or commercial air, water heaters, swimming pools and now the soil within greenhouses. Many systems are available locally through your telephone directory or through Solar energy society.Active or passive solar energy. "Active" solar energy includes the installation of electrical or mechanical devices such as solar panels or heat settings to generate electricity, heat water, or heat space, as described above. These can be added to a home or building once it is already built, but are better when it is incorporated in the new construction.
“Passive” solar involves recognizing the sun’s radiation properties to either increase the natural heating benefits of the sun or, on on the contrary, to minimize them. This is best achieved when a structure is being built or planned renovation of Windows. The basic idea for colder climates is for Windows to be orientated to the South so that the heat from the Sun in the rooms. Or, in warmer climates, to have the smaller Windows-oriented to the South and large Windows facing north. Here is a good explanation of the use of active and passive solar energy.
It is true that this is not more than a simplistic forms of solar energy discussion that they are out there. But yes displays the innovation, the width, and perhaps even shows why solar energy is the growth fastest available clean forms of energy. And, according to the latest data of employment growth, is the fastest growing of any U.S. industry., USA!
