Besides heating water, solar energy can be used to make it potable , or suitable for drinking. Developed in the s, SODIS involves filling plastic soda bottles with water then exposing them to sunlight for several hours.
This process reduces the viruses, bacteria and protozoa in water. More than 2 million people in 28 developing nations use this method daily for their drinking water. Solar power —the conversion of sunlight into electricity —is yet another application of solar technology.
This can be done in a number of ways. The two most common are photovoltaic solar cells and concentrating solar power. Solar cells convert sunlight directly into electricity. The amount of power generated by each cell is very low.
Therefore, large numbers of cells must be grouped together, like the panels mounted on the roof of a house, to generate enough power. The first solar cell was constructed in the s.
The earliest major application was on the American satellite Vanguard I , launched in A radio transmitter powered by solar cells operated for about seven years; one using conventional batteries lasted only 20 days. Since then, solar cells have become the established power source for satellites, including those used in the telecommunications industry.
On Earth, solar cells are used for everything from calculators and watches to homes, commercial buildings, and even stadiums. Kaohsiung World Stadium in Taiwan, completed in to host the World Games, has more than 8, solar panels on its roof.
Lenses or mirrors focus sunlight into a small beam that can be used to operate a boiler. That produces steam to run turbine s to generate electricity.
When completed in , Solana will be one of the largest solar power stations in the world. Once operating at full capacity, it will serve 70, homes. Janet Napolitano. There are some challenges with solar power. First, it is intermittent , or not continuous. When there is no sun—at night, for example—power cannot be generated.
In order to provide continuous power, either storage or other energy sources, such as wind power, must be used. Second, while both photovoltaic and concentrating solar power can be used virtually anywhere, the equipment they require takes up a lot of space.
Installation , except for on existing structures, can have a negative impact on the ecosystem by displacing plants and wildlife.
Lastly, the cost to collect, convert and store solar power is very high. However, as technological advancements are made and demand rises, the costs are dropping. Fossil fuels, such as coal, oil and natural gas, currently produce most of our electric and engine power.
They also produce almost all of our pollution. Plus, they are non-renewable, meaning there is a limited supply. The sun, on the other hand, offers free and clean energy in abundance.
In fact, it gives much more energy than we can ever possibly use. The only questions are how and when we will take full advantage of it. The solar panel to the right probably can't help provide electricity to the shack on the left, but it can help lower the energy costs for the neighborhood.
