Stuff To Know About

Determine Your Needs Before Buying an Portable Electric Generator

2007-10-25T16:20:00.002+05:30

Purchasing a portable electric generator is not a simple as running to your local home improvement store and just buying one. You need to determine your needs - why you need one and what you plan to power - before you set foot in a store or shop online. There are three basic reasons why a portable electric generator is desired: for leisure or entertainment, emergencies and for contracting or other professional uses.

Leisure or Entertainment Purposes

Campouts and tailgate parties are the first two reasons why someone might want a portable electric generator. It is not quite the equivalent of roughing it, but a generator can help you power up your coffee maker, waffle iron or whatever appliance you want to operate during your camping trip. As for tailgate parties, it's all about barbecuing and making drinks right? So chances are that you want to power up your little television as well as a blender at the very least.

A portable electric generator for leisure or entertainment tends to be a smaller choice than those for emergencies or professional purposes. Typically these smaller units produce 1,000 or 2,000 watts of power, enough to power from one or two appliances for the lower wattage to multiple items simultaneously for the higher wattage.

Emergency Situations

A portable electric generator must be powerful enough for the particular scenario whether it is for home use, a small business or any other situation. For instance, a small home may need a generator that produces at least 5,000 watts which will power up several appliances at the same time such as the refrigerator, freezer and maybe even a few fans or a microwave.

Unless you are prepared to pay big bucks for a portable electric generator for the entire house that kicks out 20,000 + watts for the possibility of loss of power just a few times a year, a smaller unit such as the 5,000 watt one should be fine. It is all a matter of what you perceive as important such as electric heat, basement pump to prevent flooding, security systems, life support equipment and more. You will want to determine the start-up and running wattage of each appliance that you deem important before shopping for a portable generator.

Professional Uses

A portable generator that is industrial or professional grade is only necessary if you are using it daily for jobsites that perhaps are not near electrical power sources. Heavy use as well as the number of items that you need powered is two conditions when a professional grade portable electric generator is necessary.

Benefits & Advantages of Having a Generator at Home

2007-10-25T16:20:00.000+05:30

Deciding to invest in a home generator may be one of the wisest decisions you ever make. If you have small children and live in an area that is hit frequently by severe weather, you know that having no electricity is no picnic.

Reasons to Buy a Home Generator

Investing in a home generator can allow you to use your essential appliances such as refrigerator, lights, heaters and air conditioning. There are many types of home generators from which you can choose. You can buy a portable generator, a gasoline or natural gas generator, diesel fuel or liquefied petroleum gas also known as LPG. They come in all sizes with different wattage capacities depending upon your needs.

You can also look into a standby home generator system. This type of generator can go on automatically ( Optional) or started with a simple switch. In this way you will be assured that even if you are not home, the power will be running smoothly and your food and home will be safe.

Parents of small children will really enjoy the convenience that a home generator brings. No longer will you have to worry that your child will be too cold, unable to use the bathroom, or frightened of the dark when you have a generator in your home. You can continue to cook dinner and enjoy recreational pursuits with full light, instead of trying to make do in candlelight.

You will never again have to search for matches or batteries for flashlights when the power goes out. You merely have to fire up your home generator or let the system automatically turn on and you can enjoy your life without interruption. Think of how envious your friends and neighbors will be when you are watching the big game on your TV and the rest of the neighborhood is shrouded in darkness.

Functions of Power Supply

2007-10-18T18:18:00.000+05:30

There are three functions of power supply. Those functions are generation, transmission, and distribution of electricity .
Generation is defined as the production of electric energy from other energy sources.
Transmission is the delivery of electric energy over high-voltage lines from the power plants to the distribution areas.
Distribution includes the local system of lower voltage lines, substations, and transformers which are used to deliver the electricity to end-use consumers. Prior to detailing the components of power supply along with their characteristics, this chapter will outline the three functions of power supply.

How the Generator Works

2007-09-02T17:13:00.000+05:30

All power plants have turbines and generators. Some turbines are turned by wind, some by water, some by steam.

The turbine is attached by a shaft to the turbogenerator. The generator has a long, coiled wire on its shaft surrounded by a giant magnet. You can see the inside of the generator coil with all its wires in the picture on the right.
The shaft that comes out of the turbine is connected to the generator. When the turbine turns, the shaft and rotor is turned. As the shaft inside the generator turns, an electric current is produced in the wire. The electric generator is converting mechanical, moving energy into electrical energy.

The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (or "be induced") in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.

The electricity produced by the generator then flows through huge transmission wires that link the power plants to our homes, school and businesses.

What is Electricity?

2007-09-02T17:04:00.000+05:30

Electricity figures everywhere in our lives. Electricity lights up our homes, cooks our food, powers our computers, television sets, and other electronic devices. Electricity from batteries keeps our cars running and makes our flashlights shine in the dark.

Here's something you can do to see the importance of electricity. Take a walk through your school, house or apartment and write down all the different appliances, devices and machines that use electricity. You'll be amazed at how many things we use each and every day that depend on electricity.

But what is electricity? Where does it come from? How does it work? Before we understand all that, we need to know a little bit about atoms and their structure.

All matter is made up of atoms, and atoms are made up of smaller particles. The three main particles making up an atom are the proton, the neutron and the electron.

Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth. The nucleus is made up of neutrons and protons.

Electrons contain a negative charge, protons a positive charge. Neutrons are neutral -- they have neither a positive nor a negative charge.

There are many different kinds of atoms, one for each type of element. An atom is a single part that makes up an element. There are 118 different known elements that make up every thing! Some elements like oxygen we breathe are essential to life.

Each atom has a specific number of electrons, protons and neutrons. But no matter how many particles an atom has, the number of electrons usually needs to be the same as the number of protons. If the numbers are the same, the atom is called balanced, and it is very stable.

So, if an atom had six protons, it should also have six electrons. The element with six protons and six electrons is called carbon. Carbon is found in abundance in the sun, stars, comets, atmospheres of most planets, and the food we eat. Coal is made of carbon; so are diamonds

Some kinds of atoms have loosely attached electrons. An atom that loses electrons has more protons than electrons and is positively charged. An atom that gains electrons has more negative particles and is negatively charge. A "charged" atom is called an "ion."

Electrons can be made to move from one atom to another. When those electrons move between the atoms, a current of electricity is created. The electrons move from one atom to another in a "flow." One electron is attached and another electron is lost.

This chain is similar to the fire fighter's bucket brigades in olden times. But instead of passing one bucket from the start of the line of people to the other end, each person would have a bucket of water to pour from one bucket to another. The result was a lot of spilled water and not enough water to douse the fire. It is a situation that's very similar to electricity passing along a wire and a circuit. The charge is passed from atom to atom when electricity is "passed."

Scientists and engineers have learned many ways to move electrons off of atoms. That means that when you add up the electrons and protons, you would wind up with one more proton instead of being balanced.

Since all atoms want to be balanced, the atom that has been "unbalanced" will look for a free electron to fill the place of the missing one. We say that this unbalanced atom has a "positive charge" (+) because it has too many protons.

Since it got kicked off, the free electron moves around waiting for an unbalanced atom to give it a home. The free electron charge is negative, and has no proton to balance it out, so we say that it has a "negative charge" (-).

So what do positive and negative charges have to do with electricity?

Scientists and engineers have found several ways to create large numbers of positive atoms and free negative electrons. Since positive atoms want negative electrons so they can be balanced, they have a strong attraction for the electrons. The electrons also want to be part of a balanced atom, so they have a strong attraction to the positive atoms. So, the positive attracts the negative to balance out.

The more positive atoms or negative electrons you have, the stronger the attraction for the other. Since we have both positive and negative charged groups attracted to each other, we call the total attraction "charge."

When electrons move among the atoms of matter, a current of electricity is created. This is what happens in a piece of wire. The electrons are passed from atom to atom, creating an electrical current from one end to other, just like in the picture.

Electricity is conducted through some things better than others do. Its resistance measures how well something conducts electricity. Some things hold their electrons very tightly. Electrons do not move through them very well. These things are called insulators. Rubber, plastic, cloth, glass and dry air are good insulators and have very high resistance.

Other materials have some loosely held electrons, which move through them very easily. These are called conductors. Most metals -- like copper, aluminum or steel -- are good conductors.

Sigma Explains....Where Does the Word 'Electricity' Come From?

2007-09-02T17:02:00.000+05:30

Electrons, electricity, electronic and other words that begin with "electr..." all originate from the Greek word "elektor," meaning "beaming sun." In Greek, "elektron" is the word for amber.

Amber is a very pretty goldish brown "stone" that sparkles orange and yellow in sunlight. Amber is actually fossilized tree sap! It's the stuff used in the movie "Jurassic Park." Millions of years ago insects got stuck in the tree sap. Small insects which had bitten the dinosaurs, had blood with DNA from the dinosaurs in the insect's bodies, which were now fossilized in the amber.

Ancient Greeks discovered that amber behaved oddly - like attracting feathers - when rubbed by fur or other objects. They didn't know what it was that caused this phenomenon. But the Greeks had discovered one of the first examples of static electricity.

The Latin word, electricus, means to "produce from amber by friction."

So, we get our English word electricity from Greek and Latin words that were about amber.

Electricity Production trends Around the world

2007-08-31T12:46:00.000+05:30

In 2005, USA continued to remain as the top producer of electricity with a global share of at least 25% followed by China, Japan and Russia.

Methods of Generating Electricity

2007-08-31T12:27:00.000+05:30

Methods Use for Generating Electricity are :-

1.Turbines
2. Reciprocating Engines
3. Photovoltic Panels
4. Other Geneartion Methods

Turbines

Rotating turbines attached to electrical generators produce most commercially available electricity. Turbines are driven by a fluid which acts as an intermediate energy carrier. The fluids typically used are:
steam - Water is boiled by nuclear fission or the burning of fossil fuels (coal, natural gas, or petroleum). Some newer plants use the sun as the heat source: solar parabolic troughs and solar power towers concentrate sunlight to heat a heat transfer fluid, which is then used to produce steam. Another renewable source of heat used to drive a turbine is Geothermal power. Either steam under pressure emerges from the ground and drives a turbine or hot water evaporates a low boiling liquid to create vapour to drive a turbine.
water - Turbine blades are acted upon by flowing water, produced by hydroelectric dams or tidal forces,
wind - Most wind turbines generate electricity from naturally occurring wind. Solar updraft towers use wind that is artificially produced inside the chimney by heating it with sunlight.
hot gases - Turbines are driven directly by gases produced by the combustion of natural gas or oil.
Combined cycle gas turbine plants are driven by both steam and gas. They generate power by burning natural gas in a gas turbine and use residual heat to generate additional electricity from steam. These plants offer efficiencies of up to 60%.

Reciprocating engines

Small electricity generators are often powered by reciprocating engines burning diesel biogas or natural gas. Diesel enginesare often used for back up generation, usually at low voltages. Biogas is often combusted where it is produced, such as a landfill or wastewater treatment plant, with a reciprocating engine or a microturbine, which is a small gas turbine.

Photovoltaic panels

Unlike the solar heat concentrators mentioned above, photovoltaic panels convert sunlight directly to electricity. Although sunlight is free and abundant, solar electricity is still usually more expensive to produce than large-scale mechanically generated power due to the cost of the panels. Low-efficiency silicon solar cells have been decreasing in cost though, and multijunction cells with close to 30% conversion efficiency are now commercially available. Over 40% efficiency has been demonstrated in experimental systems.[5] Until recently, photovoltaics were most commonly used in remote sites where there is no access to a commercial power grid, or as a supplemental electricity source for individual homes and businesses. Recent advances in manufacturing efficiency and photovoltaic technology, combined with subsidies driven by environmental concerns, have dramatically accelerated the deployment of solar panels. Installed capacity is growing by 40% per year led by increases in Germany, Japan, California and New Jersey.

Other generation methods
Various other technologies have been studied and developed for power generation. Solid-state generation (without moving parts) is of particular interest in portable applications. This area is largely dominated by thermoelectric (TE) devices, though thermionic (TI) and thermophotovoltaic (TPV) systems have been developed as well. Typically, TE devices are used at lower temperatures than TI and TPV systems. Piezoelectric devices are used for power generation from mechanical strain, particularly in power harvesting. Betavoltaics are another type of solid-state power generator which produces electricity from radioactive decay.
Fluid-based magnetohydrodynamic (MHD) power generation has been studied as a method for extracting electrical power from nuclear reactors and also from more conventional fuel combustion systems.
Electrochemical electricity generation is also important in portable and mobile applications. Currently, most electrochemical power comes from closed electrochemical cells ("batteries"), which are arguably utilized more as storage systems than generation systems, but open electrochemical systems, known as fuel cells, have been undergoing a great deal of research and development in the last few years. Fuel cells can be used to extract power either from natural fuels or from synthesized fuels (mainly electrolytic hydrogen) and so can be viewed as either generation systems or storage systems depending on their use.

The COncept of Electric Generator

2007-08-29T19:49:00.000+05:30

The generator moves an electric current, but does not create electric charge, which is already present in the conductive wire of its windings. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. Other types of electrical generators exist, based on other electrical phenomena such as piezoelectricity, and magnetohydrodynamics. The construction of a dynamo is similar to that of an electric motor, and all common types of dynamos could work as motors.

Global Electiricity Scenario

2007-08-27T17:34:00.000+05:30

Global electricity usage is expected to increase from 14.8 trillion kWh in 2003 to 27.1 trillion kWh by 2025, according to the U.S. Department of Energy’s Internal Energy Outlook 2005. Approximately 65.7% of the world’s electricity is currently produced with fossil fuels. As demand for electricity continues to increase, the electric power industry is facing several challenges:
• Fossil fuel supply constraints. Limited supply and escalating consumption of coal, oil, and natural gas continue to drive up wholesale electricity prices, resulting in higher electricity costs for consumers.
• Infrastructure constraints. In many parts of the world, electricity demand exceeds the capacity of existing electricity generation, transmission and distribution infrastructure.
• Desire for energy security. As political and economic instability in key oil and natural gas producing regions has increased, governments are increasingly focused on developing reliable and secure energy sources.
• Environmental concerns. Long-term use of fossil fuels is associated with a range of environmental issues including global warming, air pollution and water pollution, the increased prevalence of which is driving increased environmental awareness.
Industry and governments are considering alternatives to traditional fossil fuels to address these challenges, including renewable energy sources and technologies.

Renewable Energy Industry

2007-08-27T17:29:00.001+05:30

The renewable energy industry includes solar, hydroelectric and wind power generation, and to a lesser extent biomass and geothermal power generation. As opposed to fossil fuels, which draw on finite resources, renewable energy is generally unlimited in its availability. Hydroelectric power generation, the use of flowing water to generate electricity, is currently the largest source of renewable energy as measured by electricity generation. However, the potential for additional hydroelectric capacity in the developed world is limited due to the lack of development opportunities and environmental concerns over the creation of additional large reservoirs that flood agricultural land and human and animal habitats. Wind power generation, the use of wind turbines to harness and convert kinetic energy into electricity, is one of the fastest growing sources of renewable energy. Today, large-scale wind power is becoming a cost-competitive alternative to wholesale natural gas and coal-fired power in locations with high average wind speeds and sufficient space for large wind plants. However, space constraints, wind speed availability and zoning restrictions in suburban and urban regions limit the potential of wind power systems. Additionally, peak wind availability generally does not coincide with peak seasonal or time of day electricity use.
Due to the constraints on other sources of renewable energy, solar power has emerged as one of the fastest growing renewable energy sources. Solar power has several benefits when compared to other renewable energy technologies, including:

• No fuel price volatility. Unlike fossil and nuclear fuels, solar energy has no fuel price volatility. Although there is variability in the amount and timing of sunlight over the day, season and year, a properly sized and configured system can be designed for high reliability while providing a long term, fixed price electricity supply.

• High reliability. With no moving parts or regular required maintenance, solar power is one of the most reliable forms of electricity generation.

• Environmentally benign. Solar cells generate electricity without air or water emissions, noise, vibration, habitat impact or waste generation.

• Easily located with the end-user. Unlike other renewable resources such as hydroelectric and wind power, solar power can be utilized anywhere there is sunlight and directly where the power will be used. As a result, solar power limits the expense of and energy losses associated with transmission and distribution from large-scale electric plants to the end users.

• Peak energy generation corresponds with peak energy consumption. Maximum sunlight hours generally correspond with peak electricity demand when prices are highest.

• Applicable for a wide range of power requirements. Solar power products can be sized to meet the specific needs of the end-user ranging from very small consumer applications to larger commercial applications.

Why Should I Choose Diesel Powered Generator

2007-08-20T11:36:00.001+05:30

In today's world, where fuel prices are increasing as a consequence of spiraling demand and diminishing supply, you need to choose a cost effective fuel to meet your needs. Thanks to the invention of Rudolph Diesel, the diesel engine has proved to be extremely efficient and cost effective. Diesel fuel is priced moderately higher than gasoline but diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Therefore, diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is heavier and oilier compared with gasoline, and has a boiling point higher than that of water. And diesel engines are attracting greater attention due to higher efficiency and cost effectiveness.

THE SOLAR ENERGY

2007-08-17T17:17:00.000+05:30

Solar radiation reaches the Earth's upper atmosphere at a rate of 1366 watts per square meter (W/m2).[1] The first map shows how the solar energy varies in different latitudes.
While traveling through the atmosphere, 6% of the incoming solar radiation (insolation) is reflected and 16% is absorbed resulting in a peak irradiance at the equator of 1,020 W/m².[2] Average atmospheric conditions (clouds, dust, pollutants) further reduce insolation by 20% through reflection and 3% through absorption.[3] Atmospheric conditions not only reduce the quantity of insolation reaching the Earth's surface but also affect the quality of insolation by diffusing incoming light and altering its spectrum.
The second map shows the average global irradiance calculated from satellite data collected from 1991 to 1993. For example, in North America the average insolation at ground level over an entire year (including nights and periods of cloudy weather) lies between 125 and 375 W/m² (3 to 9 kWh/m²/day).[4] This represents the available power, and not the delivered power. At present, photovoltaic panels typically convert about 15% of incident sunlight into electricity; therefore, a solar panel in the contiguous United States on average delivers 19 to 56 W/m² or 0.45 - 1.35 kWh/m²/day.[5]
The dark disks in the third map on the right are an example of the land areas that, if covered with 8% efficient solar panels, would produce slightly more energy in the form of electricity than the total world primary energy supply in 2003.[6] While average insolation and power offer insight into solar power's potential on a regional scale, locally relevant conditions are of primary importance to the potential of a specific site.
After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and infrared radiation. Plants use solar energy to create chemical energy through photosynthesis. Humans regularly use this energy burning wood or fossil fuels, or when simply eating the plants.
A recent concern is global dimming, an effect of pollution that is allowing less sunlight to reach the Earth's surface. It is intricately linked with pollution particles and global warming, and it is mostly of concern for issues of global climate change, but is also of concern to proponents of solar power because of the existing and potential future decreases in available solar energy. The order of magnitude is about 4% less solar energy available at sea level over the timeframe of 1961–90, mostly from increased reflection from clouds back into space.[7]

Types of technologies

Many types of technology have been developed to make use of solar radiation. Some of these technologies make direct use of the solar energy (e.g. to provide light, heat, etc.), while others produce electricity.
