with his friends invented an innovative bird feeder that worked on solar power. The feeder used a small solar panel in its roof to build an electric charge. The Solar feeder’s purpose is to use the mild electric shock it generates to repel the squirrels‚ preventing them from stealing the bird seed or damaging the feeder itself. In a typical product-driven approach‚ Bo and his friends started SDI‚ Inc. to produce and promote the solar feeder without having done any marketing plan. After several years

The local council of Greenville recently made a proposal for all houses and businesses to install solar hot-water systems by 2010. Houses and businesses that who have not installed solar hot-water systems by then would be charged a “greenhouse levy”. However some residents have expressed anger over the proposal. “Solar Sellout” published in a local newspaper‚ an opinion piece and its accompanying cartoon written Bob Walsh‚ contends that the proposal which aims to reduce greenhouse gas emissions is

“Solar Treated Purification” Intorduction: A. Background of the study: In our world today‚ purified water is the one that most of the people drink everyday especially those who live in cities. Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed

The Tropical Rainforests There are many different ecosystems on this planet. They include tundra’s‚ desserts‚ grasslands‚ etc. However‚ the tropical rainforest is truly the world’s most diverse biome in both structure and species diversity. The Tropical rainforest is characterized by a dense growth of trees and by the continuously canopy that is formed by the broad- leaved Evergreen trees. There is also large amounts of precipitation annually and there is no dry season‚ which is a major factor

The relationship between climates‚soil and vegetation of Tropical marine areas‚ Tropical continental areas and Equatorial areas. Climate In tropical marine areas‚the ocean is largely responsible for creating the tropical marine climate system.In these areas there are two seasons‚ the wet season and the dry season. The average temperature ranges from 25-35 degrees celsius.The annual rainfall is between 1000-1500 mm . The trade winds in this area blow all year and are moist because they pass

green is not strictly a new technological concept‚ and any naturally occurring and theoretically inexhaustible energy such as wind‚ biomass‚ and solar‚ tidal‚ wave‚ hydroelectric power that is not derived from fossil or nuclear fuel is referred to as renewable energy. The relevance of these emerging fields became more pronounced when the need to produce clean‚ safe and efficient energy devices without trading off environmental friendliness arise. The current electricity production from fossil fuels

from the Earth‚ a solar eclipse occurs when the Moon passes between the Sun and Earth‚ and the Moon fully or partially blocks the Sun. This can happen only at new moon‚ when the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse‚ the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses only part of the Sun is obscured.If the Moon were in a circular orbit close enough to the Earth and in the same orbital plane‚ there would be total solar eclipses every

Thesis statement: Solar eclipse‚ it effects on mankind and the earth. I decided to choose this topic because I was thrilled the first time I heard stories about them and since then I been wanting to know more about it effects on mankind‚ earth and what caused it to happen. I didn’t do any research on it before choosing it however I wanted to know if it has any effect at all and what causes solar eclipse in the first place. I guess I can say my curiosity led me to this sentence. I do not have any

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 can

The tropical monsoon climate is found in those regions where there is a complete seasonal reversal of winds. It is mainly found beyond the equatorial region between 10° and 25° North and South of the Equator. On-shore summer winds blowing from over tropical warm oceans generate the abundant precipitation‚ while the off-shore winds from over land make the weather dry during winter. The most clearly defined monsoon climates are located in the coastal areas of the eastern and southern Asia. For example
