Solar thermal electric generation is a means of producing electricity in which the sun's energy is concentrated using mirrors or lenses onto a fluid-filled pipe; the heated fluid is used to generate electricity. They often have a backup which is natural gas to generate electricity at night and during cloudy days when solar power isn't operating.…
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 not appropriate for the small suburb of Greenville. Walsh uses a sarcastic and angry tone which is quite personal, and aims to clearly outline why the proposal by the government is a bad idea.…
Solar cars combine technology typically used in the aerospace, bicycle,alternative energy and automotive industries. The design of a solar vehicle is severely limited by the amount of energy input into the car. Most solar cars have been built for the purpose of solar car races. Exceptions include solar-powered cars and utility vehicles.…

Lawn mowers are something that can’t be misunderstood like most ads they are a product that is needed for a person who owns a house are trying to start a business. In this ad men are being manipulated on the great looks of riding lawn mowers.…
In today’s economic market, efficient energy is the main challenge. I think that our economy needs, in stipulations of energy involve transportation division, and residential and commercial divisions. Our society is extremely dependent on the non-renewable supply for our energy requirements. These resources will diminish over a point in time; they are the main ingredients for pollution, and this is a huge concern for the country. To tackle these challenges we need to come up with the new facts that help plummet…

So, I was a little surprised to stumble across this story about a city car prototype that is only powered by solar power. The car is apparently being developed by 6 European companies, and it has been awarded €2.8 million in funding. Tehran Times writes:…
Solar power, in its most basic form, is the conversion of sunlight into electricity both actively and passively. Solar energy uses an amalgamation of photovoltaic panels, pumps, and fans to convert sunlight into useful outputs. The actual solar cell is made from a monocrystalline silicon wafer, where silicon is the world’s eighth most common chemical element. Depending on where solar panels are placed will determine the…
Photovoltaic (PV devices) or “solar cells” – change sunlight directly into electricity PV systems are often used in remote locations that are not connected to the electric grid. They are also used to power watches, calculators, and lighted road signs.…
1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell’s Equations indicate that the electromagnetic field and its power diffuse to all directions. Although we transmit the energy in the communication system, the transmitted energy is diffused to all directions. Although the received power is enough for a transmission of information, the efficiency from the transmitter to receiver is quiet low. Therefore, we do not call it the WPT system. Typical WPT is a point-to-point power transmission. For the WPT, we had better concentrate power to receiver. It was proved that the power transmission efficiency can approach close to 100%. We can more concentrate the transmitted microwave power to the receiver aperture areas with taper method of the transmitting antenna power distribution. Famous power tapers of the transmitting antenna are Gaussian taper, Taylor distribution, and Chebychev distribution. These taper of the transmitting antenna is commonly used for suppression of sidelobes. It corresponds to increase the power transmission efficiency. Concerning the power transmission efficiency of the WPT, there are some good optical approaches in Russia[5][6]. Future suitable and largest application of the WPT via microwave is a Space Solar Power Satellite (SPS). The SPS is a gigantic satellite designed as an electric power plant orbiting in the Geostationary Earth Orbit (GEO). It consists of mainly three segments; solar energy collector to convert the solar energy into DC (direct current) electricity, DC-to-microwave converter, and large antenna array to beam down the microwave power to the ground. The first solar collector can be…
As renewable energy source, solar energy presents an exciting opportunity. While the current contribution of solar energy to the total global energy needs is insignificant, in the medium and long run, it is expected that solar energy will form a vital component of the world’s energy mix. This has resulted in a number of countries, communities and companies investing significantly into solar energy.…
Concentrated Solar Power (CSP), also known as solar thermal power is a renewable energy source that uses the Sun’s radiation to produce electricity. There are three different types of CSP plants. One type is a parabolic trough where long curved mirrors pivot to concentrate sunlight onto tubes filled with a heat transfer fluid, generally oil and water, whose steam moves a power generating turbine [1]. The second type is a dish -engine combination. Mirrored dishes (resembling those for satellite television) track the sun and concentrate its heat onto a power-generating unit that has an engine powered by a heat-responsive fluid [1]. The third type is known as a power tower system that consists of a field of mirrors that focus sunlight onto a tower which contains a solar receiver containing heat transfer fluid, such as water or molten salt.…
Renewable sources of energy are being used worldwide to overcome the pollution problems related to oil and gas industry plus the use of natural gas that cost a lot of money and produce heaps of waste that affect the environment and cause air pollution and land/marine pollution. Therefore the solution was to invest in friendly and clean energy and technology and one of that is the enhanced oil recovery which mainly use CO2, thermal and chemical technologies to increase the production efficiency of oil/gas wells, reduce the pollution produced from oil field and reduce the use of natural gas that can be used in other sectors like generating electricity, and industrial sector.…
Solar energy in one form or another is the source of nearly all energy on the earth. Humans, like all other animals and plants, rely on the sun for warmth and food. However, people also harness the sun's energy in many other different ways. For example, fossil fuels, plant matter from a past geological age, is used for transportation and electricity generation and is essentially just stored solar energy from millions of years ago. Similarly, biomass converts the sun's energy into a fuel, which can then be used for heat, transport or electricity. Wind energy, used for hundred of years to provide mechanical energy or for transportation, uses air currents that are created by solar heated air and the rotation of the earth. Today wind turbines convert wind power into electricity as well as its traditional uses. Even hydroelectricity is derived from the sun. Hydropower depends on the evaporation of water by the sun, and its subsequent return to the Earth as rain to provide water in dams. Photovoltaics(often abbreviated as PV) is a simple and elegant method of harnessing the sun's energy. PV devices (solar cells) are unique in that they directly convert the incident solar radiation into electricity, with no noise, pollution or moving parts, making them robust, reliable and long lasting. Solar cells are based on the same principles and materials behind the communications and computer revolutions, and this CDROM covers the operation, use and applications of photovoltaic devices and systems.…
