The Controversy of Harnessing Solar Energy We often hear about solar cars, solar heating, and solar batteries. But will solar energy ever be a major source of energy for society?Solar energy is cheaper than other fossil fuels because we can get an abundant source from the sun. In sunny desert areas, 50% of the sun’s radiation that reaches the ground could be used to produce electricity for businesses and industry and to provide heat, light, and hot water for homes.

Experimental solar ponds can also produce hot water to drive generators.Unfortunately, we can’t yet power our homes entirely on sunlight. Solar energy can only be used effectively in bright light. Its greatest potential therefore is in hot countries that have clear skies for most of the year. But, unfortunately most houses are not in the sunniest parts of the world.
Moreover, in order to harness solar power solar cells are very cheap to run, but relatively expensive to buy and many people can’t afford them.Needless to say, solar energy is a useful and non-pollution source of energy. Unfortunately, solar cells, the main device to harness the sun’s energy are still very expensive.Where can solar energy be used effectively?

MODEMModem is a device that enables computers, facsimile machines, and other equipment to communicate with each other across telephone lines or over cable television network cables. In the strictest sense, a modem is a device that converts between analog signals, such as sound waves, and digital signals, which are used by computers. However, the term has also come to include devices that permit the transmission of entirely digital signals.
Modems transmit data at different speeds, measured by the number of bits of data they send per second (bps). A 28.8 Kbps modem sends data at 28,800 bits per second. A 56 Kbps modem is twice as fast, sending and receiving data at a rate of 56,000 bits per second.What does paragraph 1 tell us about?.

ENCYCLOPEDIA Encyclopedia or Encyclopedia is a reference work that provides information on a range of subjects. Encyclopedias can encompass many areas of interest, or they can focus on a particular field of study, such as a geographic area, an ethnic group, a time period, or an academic discipline. Most encyclopedias have hundreds or thousands of articles, each addressing a distinct topic. Many of the articles contain illustrations, maps, photographs, and other media elements that help readers understand concepts.
For centuries encyclopedias were published as multivolume sets of books, but in the late 20th century they appeared in new formats, such as CD-ROM, digital video disc (DVD), and on the Internet. The term encyclopedia comes from the Greek words enkyklios paideia, meaning “comprehensive education” and originally signifying instruction in all branches of knowledge, or a comprehensive education in a specific subject.
This concept gave rise to the idea of collecting the materials for such instruction into a single work, in which the contents and relations of the various arts and sciences would be explained systematically. Attempts to produce books of this kind were made more than 2,000 years ago, although the name encyclopedia was not given to such works until the 16th century. How are the encyclopedias published?.
