Concentrated Solar Power An Analysis on Solar Thermal Power and its Application Hassan Almutawa and Chavis Sabin Abstract Concentrated Solar Power (CSP) is a renewable energy source that converts the radiation from the Sun into thermal energy. CSP plants collect solar energy throughout the day and can continue to provide electricity for up to six hours after dark using thermal storage. CSP plants can only be built in arid flat areas with a high annual solar radiation rating. Many countries

Lucky Koritela #23 The Rock Cycle The rock cycle begins when Earth’s plates shift around leaving gaps in between them making a volcano. The magma under Earth’s crust come through the gap and spill out of the volcano. Then the magma (lava) cools down and hardens into igneous rock. As time passes the igneous rock weathers (using substances such as water) away into little chips. After getting smaller‚ erosion (using elements such as wind) transports the little rocks to different places. The deposition

bulb" now exists that does not use any conventional energy. Introducing the Solar Bottle Bulb -- an alternative source of daylight powered by the sun. It is made from an old soda bottle. By filling it with water and sealing it into the roof‚ the water refracts the sun’s rays and provides about 55 watts of light to a darkened room. This was invented in 2006 by students at the Massachusetts Institute of Technology (MIT). It can be built and installed in less than 1 hour‚ and uses inexpensive
