Even though only a small fraction of that heat ever reaches the solar power essay it is still more then enough to power the whole world.
People seemed to realize the importance of the sun around 30, BC, solar power essay. This was when people first started planting crops of wheat. They realized plants did better when solar power essay in the sun over the shade. This caused them to worship the sun as a God. Many cultures built large and extravagant temples to worship the sun in. Other cultures built places to observe the sun in, such as Stonehenge in England.
There are three main types of solar panels. They are flat plate collectors, focusing collectors, solar power essay, and solar cells, solar power essay.
The first kind is a flat plate collector. Flat plate collectors are fastened on the top of the roof of solar power essay house.
They usually either heat the house or its water. A flat plate collector consists of a black rectangular frame, two or three sheets of glass, and copper plumbing. A flat plat collector uses the greenhouse affect. The sunrays heat the water-filled copper tubes, solar power essay. Then the water is used to heat the home or water. Another type of a solar panel is a focusing collector.
They consist of a mirror or mirrors which are focused in one spot. Some focusing solar power essay are solar furnaces, parabolic dishes and troughs and power towers. The first type is a solar furnace. A solar furnace consists of many mirrors that are aimed at a large curved mirror that is aimed at a large steel building.
This building can get as hot as 5, F. Scientists use solar furnaces to run experiments to see how certain materials react to extreme heats. They are also used industrially to melt metals, solar power essay.
The next kind of focusing collector is a parabolic trough and dish. A parabolic dish looks just like a satellite dish except the dish part is to reflect the sunrays onto the vocal point which is filled with oil.
The heated oil is used to produce steam to turn a turbine, solar power essay. A parabolic trough uses the same principles as a parabolic dish. The only differences are how they look, solar power essay mirror is shaped like a large feeding trough and the vocal point is an oil filled tube. These are used for either commercial such as in a power plant. The last focusing collector is a power tower. A power tower has many mirrors all focused on a large tower.
This tower gets extremely hot. The tower is filled with oil. When the oil is heated it is piped to a power plant where it is used to produce steam that turns a turbine. These are used for power plants. The final type of solar panel is a solar cell.
A solar cell usually consists of two layers of silicon that produce an electric charge which solar power essay picked up by wires that are laid across the silicon. Solar cells can be used for anything from powering an isolated phone booth to a whole city or even an airplane. Solar Energy started around 30, BC when solar power essay first desalinized water, or took the salt out of salt water.
In 1, BC a king had the water in his castle heated by the sun, solar power essay. Romans passively heated their homes in about AD. In a passive solar home there is no machinery, but there are windows and the floors and windows are made of materials that absorbs heat, like adobe.
Solar heating was not used until the late sixteenth century when European scientists started experimenting with the power of the sun. In a Swiss scientist, Horace Benedict de Sasure, built the first modern solar water heater. In Antoine Lavoiser made a printing press powered by the sun. Later in in Chile a solar desalinization system was made. Also in the first solar cells were made. Solar cells when originally made they were very expensive and were not available on the market.
Now you can buy solar cells cheaply. Today we use solar power to do many things. We use solar power for everything from calculators to large power plants that can power large cities. Most common solar power is used for small things. Many calculators are run by solar cells so they will never run out of batteries, solar power essay.
Some watches run on solar cells, too. Also you can buy radios that run on solar cells. There are also many big things that run on solar power. Almost all satellites run on solar power, because otherwise they would run out of power. There are also large desalinization plants that use solar power in places where there is solar power essay or no fresh water. There are solar furnaces in many countries. Solar power is also used commercially and residentially.
It is also used for many forms of transportation, but these are all in the experimental stage now. Solar powered cars may soon come out. There are three forms of indirect solar power.
They are wind power, waterpower, and ocean thermal energy. You might think these have nothing to do with each other or solar power but they do, in some way they each use the sun.
The first type is wind power. The reason this is a form of solar energy is because the sun heats the air that creates air currents, solar power essay, or wind.
The wind turns propellers that turn turbines which creates electricity. Wind power has been used for a very long time. Places in Europe like the Netherlands have had windmills since the Middle Ages. Though these windmills were used to pump water or to grind grain. The next form is waterpower. This is considered solar power because of the hydrologic cycle.
The hydrologic cycle is water evaporating from bodies of water then coming back to earth in different places. This allows them solar power essay go back through dams to produce electricity.
The water turns turbines, which then create electricity. Waterpower is also an old process it used solar power essay be used at sawmills and to grind down grain. The last kind of indirect solar power is ocean thermal energy. Ocean thermal energy is a power plant that uses the difference between the surface temperature and the temperature of the bottom of the ocean to produce electricity.
When the cool water meets the hot water it produces steam that turns a turbine to produce electricity. The electricity is then sent to land through wires. This is solar power because the sun heats it. Today the use of solar power is very limited.
Today we use very little active solar heating, solar power essay. Though in the future many more homes will be solar heated. More homes will have passive solar heating, solar power essay.
Scientists want to make a satellite that will orbit over one place, solar power essay. This satellite would have giant wings made of solar power, this satellite would beam electricity down to earth. This would allow the solar cells not to be obstructed by clouds or buildings. Also ground solar power plants are predicted to be used more frequently.
Another thing predicted to be popular is solar powered cars.
