Solar Cells and Solar Panels
Filed under Alternative Energy
About hundred years ago, it was discovered that when sunlight falls on a thin layer of selenium (called wafer a selenium), electricity is produced. The efficiency of this conversion of solar energy into electric energy was very low (about 0.6%). This means, out of 100 J of solar energy falling on the selenium wafer, only 0.6 J could b converted into electricity. However, this was the first solar cell.... [Click here to Read more]
Different Types of Solar Cookers
Filed under Alternative Energy
Solar cookers are gaining a lot of popularity these days. There are two types of solar cookers used- Box type solar cooker and reflector type solar cooker. Box type solar cooker contains a plane mirror that increases the amount of sunlight inside the box. The temperature inside the box becomes 100°C—140°C in about two to three hours. This time depends on the intensity of the sunlight. In summer,... [Click here to Read more]
Advantages and Limitations of Solar Heating Devices
Filed under Alternative Energy
In years gone by the use of solar energy was very limited. It was mainly used for drying clothes food grains, etc., and making salt from sea water. But now the scenario has changed vastly. The current applications of solar energy are: (a) Cooking food (b) Heating buildings in winter (c) Operating calculators, etc. (d) Running solar power plants to generate electricity (e) Providing electric power...

Nuclear Fusion in the Sun
Filed under Alternative Energy
When light nuclei collide with each other, they may fuse together to form a heavier nucleus. The process is known as nuclear fusion and energy is released in such a process. However, fusion of nuclei is not an easy process. A nucleus is a very small particle having radius of the order of only 10 m. To fuse into one nucleus, the individual nuclei should come very close to each other, say, within about... [Click here to Read more]
