Background * Three solar energy * Solar electric (太阳电能): convert the sun’s energy into electricity * Solar thermal (太阳热能): used the sun for heating or cooling * Concentrating solar: mixed both above as it used small optical mirrors to collect solar energy and convert the sunlight to heat. The heat was then applied to a liquid and gas to turn a turbine‚ thereby creating electricity * Grid-tied * Solar electric system that were connected to an electricity utility

“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 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 power satellites Introduction The Sun is a very powerful‚ clean and convenient source of power‚ particularly for satellites. The only thing needed is a means to convert the energy contained in the Sun’s radiation – mainly light and ultraviolet rays – into electrical power. The most efficient way to achieve this today is by using panels composed of semiconductor photovoltaic cells. ‘Solar panels’‚ as they are usually called‚ are now quite a common sight here on Earth‚ but they were first used

Architectural Solar Systems Present day architecture has advanced in many ways. A style of architecture which could prove to be very beneficial to Earth and its people in the future is solar energy architecture; the use of sun to channel energy and maintain a household. Solar energy still seems a mysterious subject to many people. According to Roy Erving in The Architectural Handbook‚ they make it seem as complicated as “putting a man on the moon.” To put it simply most people believe that solar energy

Solar Panels : Solar panels are an eco-friendly electric generator. Solar panels generate electrical power from the sun by converting sunlight to electricity with no moving parts‚ zero emissions‚ and no maintenance. The solar panel‚ the first component of a electric solar energy system‚ is a collection of individual silicon cells that generate electricity from sunlight. The basic component of a solar panel is solar cell or photovoltaic cell. Solar cell: A solar cell or photovoltaic cell

Solar Absorbers and the Future of Electricity Solar Absorbers and the Future of Electricity By James Folta Electricity is what we use to power things at home or at school. You can probably look around right now and see an electrical outlet or two. Everything that we plug into one of these outlets uses electricity. But where does this electricity come from? Right now we have a few ways to make electricity. Some are better than others. There are some scientists who are trying to find

Solar Energy The Sun is a star and without it there would be no life on earth. This is why the Sun is called the ultimate source of energy. The Sun’s energy is produced by a process called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered

Characteristics A solar panel is a collection of many small solar cells spread over a large area. These solar cells work together to provide sufficient energy to power a given item. (Northwestern University) Their creation is a very delicate process which is why many of their advancements did not come until last quarter of the 20th century. In this period‚ advancements in semiconductors and photovoltaic products allowed efficient and cost effective solar panels to be produced. (Solar Panel Info)

First slide: The purpose of “Solar paint” invention is to generate inexpensive electricity because various efforts have been made for this kind of power generation over the previous few decades. It is an environment friendly technology which has eliminated the need of solar cell. It is completely reasonable and sustainable. Solar paint is consisted of organic solar cell paint. These organic solar cells are protected from water through ecofriendly synthetic sheets for example PET and therefore
