Sustainable Power Of The Wind

With so much talk about environmental damage, dwindling fossil fuels, and sky rocketing oil and energy prices it is now clear that we must look for alternative energy resources that will be able to supply our endless needs without the possibility of it being exhausted.

A Brief Lesson in History

A sustainable energy source since ancient times, the power of the wind has been harnessed by sailors, farmer, and architects alike. In times long gone, from 5,000 years ago and rediscovered again today the Egyptians used wind power to propel their sailing vessels, and Babylonian architects use architectural designs to make use of the wind to ventilate their palace and temple complexes.

As early as 300 B.C. the Sinhalese bygones used monsoon winds to power their furnaces. Constructed right where monsoon winds pass the furnaces were powered up to 1100 to 1200 centigrade. In the 1st century AD the first ever primitively built windmill was used to power an organ. Later during the 7th century the first and most primary windmill was built in Afghanistan in a small town called Sistan. The Windmill has a vertical axle with blades shaped like a rectangle and with a long driveshaft. In the 1100’s wind mills were built to grind flour, for sugar manufacturing and the gristmilling industries. The Dutch built windmills that stand until this day.

Beneath Power Is Wind

The Sun unevenly heats the Earth that differences of heat distribution; the poles receive less than the equators do. Unlike the land, the oceans, seas and rivers do not have covering so it retains more heat than soil. This contrast results in a global atmospheric convection that reaches from the stratosphere and into the earth’s surface. Energy in these wind movements are stored at high altitudes where in the wind can achieve speeds up to 160km/hr. Here after with the effects of friction the wind’s energy is diffused into heat throughout the planet and its atmosphere. This vast amount of sustainable power can provide us unimaginable amounts of energy, far more than we currently consume.

Wind Speed Distribution

Wind varies in strength. The average value of a certain location does not specify the energy of a single wind turbine. The wind speed’s frequency can be assessed in a particular location, they are fitted by a probable distribution function to the particular observed data. Different wind distributions varies from different locations, hourly wind speeds at different locations are being monitored by the Rayleigh model, which basically means a continuous probability distribution which was named after Lord Rayleigh.

Electrical Generation

Using the power of electricity from a wind farm is usually fed through a network of electrical power transmissions. This is done by connecting the individual turbines with a medium voltage power system and a series of communications networks. The electrical current is then increased with a transformer to be able to connect to the high voltage transmitting system. System operators supplies the wind farm owner with a code that indicates requirements to be able to connect to the transmission grid which includes the power factor, the constancy of the frequency and the behavior of the wind turbines when experiencing system faults.

Now that we know that the speed of wind is not constant, a farm’s energy production is not as much as the sum of the nameplate rating being multiplied by the year’s total hours being used. The ratio of this productivity in a whole year is called the capacity factor. This is the ratio of productivity in a year to this theoretical maximum.

Why you should fuel your generator with natural gas

Why you should fuel your generator with natural gas

For those people who have invested or thinking about investing in a power generator for back-up power needs, extra electrical needs, or portable electrical needs, a big consideration should be the type of fuel that is used. There are many sources of fuel for providing electrical energy from the generator including gasoline, natural gas, diesel, solar, wind, and a few other fuel sources as well. The type of fuel selected for a generator can have big impacts on everything from the environment, cost, and electrical output. Sources like gasoline and natural gas are non-renewable where as solar and wind come free and are renewable. For continuous, high energy output, gasoline and natural gas are better fuel sources. These are just a few of the considerations. Natural gas, however has some major points over the other fuel sources and is recommended in this article.

Why is natural gas a good fuel source for generators? Well first of all, a lot of homes use natural gas to fuel stoves, ovens, and even fireplaces. Those who have paid the gas bill will often find it is much cheaper than the electrical bill. For those unlucky people with electric ranges, electric water heating, and other electricity dependent heating, the high price of electricity is a big cash vacuum. The price of natural gas is very good compared to other fuel sources as well. The energy output provided verses the cost is better than that of diesel and gasoline.

When it comes to generators, most backup generators work better with natural gas because the supply is already coming to the location. Most homes have a pipeline for their natural gas that can be harnessed by backup generators to supply electricity when other sources are not working. Automatic transfer switches can determine when there are blackouts or other electrical problems and supply electrical power produced from the location’s natural gas source. This means that there is no need to purchase any additional fuel for the generator as it is already pulling from a decent costing fuel source in natural gas. This can not be achieved with some of the other fuel sources as well.

Another reason natural gas should be used in power generators is it’s energy production which is comparable to that of gasoline and diesel. For people who have natural gas products, the energy output is not even noticeable but the cost is. Natural gas makes the energy to cost ratio efficient. For portable generators, the same output can also be achieved as natural gas can be supplied to the generator much like how a barbecue grill is supplied. This makes supplying fuel to portable units easy as all that is needed is a canister of natural gas that just needs to be plugged in to the fuel line.

Natural gas is also cleaner than both diesel and gasoline. Natural gas will cause less engine buildup and lead to longer lifetime of a costly generator. There are also natural gas conversion kits for many types of generators that allow changing the fuel type. These conversion kits can help extend the usefulness of old generators by using natural gas as the fuel type instead.

Natural gas is not only a good energy source for homes but also a good one for portable or emergency power generators as well. They provide high, continuous amounts of energy at a very efficient cost to both residential and business users.

What You Should Know About Portable Generator Safety

What You Should Know About Portable Generator Safety

Portable electric generators provide a good source of power, but if improperly installed or operated, can become deadly.

To keep families safe, The Electrical Safety Foundation International (ESFI) and Consumer Product Safety Commission (CPSC) offer a helpful new video and recommend taking the following precautions:

• Contact a licensed electrician to install your generator to make sure it meets local codes. Do not connect generators directly to household wiring without an appropriate transfer switch installed.

Power from generators connected directly to household wiring can backfeed along power lines and electrocute anyone coming in contact with them, including lineworkers making repairs. Other tips include:

• Make sure your generator is properly grounded.

• Keep the generator dry.

• Make sure extension cords used with generators are rated for the load, and are free of cuts and worn insulation and have three-pronged plugs.

• Do not overload the generator. A portable generator should be used only when necessary and only to power essential equipment or appliances.

• Never operate the generator in enclosed or partially enclosed spaces. Use carbon monoxide detectors in nearby enclosed spaces to monitor levels. Generators can produce high levels of carbon monoxide very quickly, which can be deadly.

• Use a ground fault circuit interrupter (GFCI) to help prevent electrocutions and electrical shock injuries.

• Make sure fuel for the generator is stored safely, away from living areas, in properly labeled containers and away from fuel-burning appliances. Before re-fueling, always turn the generator off and let it cool down.

• Turn off all appliances powered by the generator before shutting down the generator.

• Keep children away from portable generators at all times.

Electricity is a powerful tool. It can also be a lethal hazard. Better safety standards have reduced electrical hazards that cause deaths, injuries and property damage. But good safety habits are still the best prevention against electrical hazards.

Wind Turbine Generators – Free power from mother nature. Maybe we could install it now

Wind Turbine Generators – Free power from mother nature. Maybe we could install it now

Wind generators are one of the most reliable forms of alternative power sources on the planet. They are made to manufacture power by transforming the kinetic energy of the wind into mechanical energy, which is then either harnessed directly (in the case of windmills, for example, which were used to change wheat into flour, or to pump water for farming) or coupled to a generator that creates a DC output that can be used in a more general sense. In this article I will be talking about the type of wind generators that produce electric energy, as this is more useful to us in our daily lives.

Wind turbines are basically large windmills, with gigantic blades that rotate in the wind and produce power from the conversion of the winds force. Wind turbines are manufactured from plastic, aluminium, steel and numerous other space age metals.

Wind turbines have a few negative impacts on the environment. They are very visible, and quite unsightly since they must be put in proximity to windy, open terrain to be useful – attempts to locate them off the coast have been met with great success. They require a great deal of energy in their manufacture, energy which is typically fossil-based, and therefore it can take a considerable amount of time before they are positive in terms of total carbon emissions – this time can be anywhere from 2 to 5 years. Wind turbines are linked to the mauling of rare species of birds that can be mutilated as they pass through the turbine fans during migratory passages.

With all of the downsides aside, wind turbines should be a choice when talking about a broad plan for renewable energy. Once erected, wind turbines are amazingly efficient in a larger sense – they generate power from a natural, eco-friendly renewable resource, without the hidden social or environmental penalties that we incur with the use of fossil fuels – theres no need to mine for fuel or to transport it – there are no global warming pollutants created, and no need to store, process, or to dispose of toxic wastes.

At the small side of the scale, turbines can be as tiny as 5 feet in diameter and are capable of only a few hundred watts. On the high end of the spectrum, turbines can be as huge as three hundred feet in diameter and are capable of generating two to five megawatts of power.

Similar to photovoltaic solar power generation, there might be rebates available for construction, and excess energy can be sold back to the power company.

Wind velocity is impacted by topography and increases with height above the ground, so wind turbines are generally installed on top of large towers. In a typical application, the wind turbine sits on top of a tall tower and generates low voltage DC which is used to charge a battery store – this stored potential energy is ultimately utilized by routing it through an inverter that changes the low voltage direct current power into utility voltage alternating current electricity that can be used in household applications. By concentrating a lot of turbines into wind farms a substantial amount of electricity can be stored and utilized, perhaps for a whole city or town.

Because the wind doesnt blow all of the time in many areas, wind turbines are used as adjuncts in hybrid configurations with many different technologies like photovoltaic panels, and diesel generators to provide a consistent source of electricity.

Dissimilar to fossil-fuel stations, wind turbines are clean and green – they dont create the carbon dioxide emissions that are causing greenhouse gases or the SO2 emissions that cause acid rain.

Todays turbines are divided into 2 categories, namely horizontal turbines and vertica turbines. Todays horizontal axis wind turbines are actually far better at capturing the wind than vertical axis turbines given the same amount of swept area (which is the diameter of the circle traced by the outside tip of the rotor blades).

Solar Power or the Use of Generators

Every year, the environmental problems are getting worse. Global warming, pollution, and other concerns are now very evident. Many environmentalists are now taking an active part in the hope of saving the world before it’s too late. One way to effectively address such problems is by using solar power. With many households and establishments using generators to back up their power supply, which do you think is the best choice?

Power failure happens in the most unexpected hours and so having a generator can provide the needed power. The portable generators are widely used and you can even find large generators that provide emergency power. If you want to help in reducing pollution and other environmental problems, why don’t you opt for solar power instead?

The initial cost is a very important consideration but you will also need to look in the benefits that you can gain the future. Installing a viable solar power system can be quite expensive than just purchasing a portable generator. However, once you’ve installed the power system, you can already enjoy free unlimited power supply. Maintenance is minimal and you will not spend huge money on it. You don’t need to buy fuel just to run the system because the energy of the sun fuels the solar power system. In a portable generator, you will need to buy fuel to run it and so you will continue to spend money to enjoy power supply.

Generators can be purchased easily, online or locally, and so it’s quite convenient to obtain them. On the other hand, solar power is not that convenient to install and purchase as well. The market for solar power is rather small but because of the technological advancements, the market will soon grow. Today, the best way to obtain solar power kits is through the internet. Anyone can settle for a little bit of inconvenience especially if huge benefits are involved. Besides, after the installation of the solar power system, you don’t need to monitor it often unlike in generators where you will refill the fuel, change the oil and filter, and two times servicing in a year. The solar power system can last for twenty years even with minimal maintenance.

Both solar power and portable generators are efficient. However, when it comes to cost-efficiency, solar power is ahead. As long as the sun shines, energy can be generated. The system can also store energy so that it can be used at night or during rainy days. In a generator, you will need to re-fuel from time to time. You will need to pay for the fuel every time. Sunlight is free but fuel is not and so the cost efficient option is very obvious.

In terms of dependability, solar power and generators are almost the same. Solar power is best used in places where there is bright sunlight all throughout the year. If the period of bad weather is lengthy, all the stored power can be consumed. Generators can be used whether it’s sunny or rainy but the problem lies with the source of fuel. If you can’t refuel the generator, it will not work.

It’s your choice whether you will use solar power or a portable generator. It all depends on your capacity to pay for the device. You can further evaluate these two by reading this article carefully.

Make Colloidal Silver Generator

Make Colloidal Silver Generator

Since the appearance of books and articles on colloidal silver more than two years ago, the public eye is turned once again on this much debated about antibiotic supplement. Now, colloidal silver products can be found on the shelves of almost every health store in the US.

Prices greatly vary. Before the recent furor over colloidal silver, one could pay as much as $10 per oz. of the solution. Today, while that there are still products well around that price range, you can actually get it for $5 per oz. and sometimes even for as low as $2.50 per oz.

So what’s driving down the prices of colloidal silver?

The most obvious reason could be the number of colloidal silver generators that have recently cropped up. These devices are simple enough to build, making it easy enough for ordinary consumers to buy or make colloidal silver generators and produce their own colloidal silver supply.

However, to make colloidal silver generators is not as simple as you may believe. If this is not your first time to make colloidal silver generators, then the stuff you may be using might be an inferior product.

Consider the following critical factors when you make colloidal silver generators:

* Particle size
* Purity
* Concentration
* Cost

Cost is easy enough to determine. However, when it comes to particle size, purity and concentration, you need a laboratory analysis to get accurate results. To determine particle size, you need an electron microscope photograph. For Purity, mass spectroscopy or x-ray defraction analysis. And for concentration, it is best determined by analyzing the total dissolved solids.

The advantage when you make colloidal silver generators is that, even though laboratory testing might not be possible, you still have a good idea on how to control the four critical factors, which is more than what one can say about a lot of commercial products out there. Generally speaking, commercial products vary in their quality control per batch thus making it impossible, without laboratory testing, to determine whether you are really getting “real” colloidal silver or an inferior product.

To make colloidal silver generators, you need batteries (9-volt transistor radio batteries will do), some wires with insulation, pure silver (.999 fine), and glass container filled with distilled water which shall form your liquid base.

Moreover, when you make colloidal silver generators, pay special attention to the high quality of the water. This is because the water is an important factor in controlling how tiny the particle size of silver being produced. Use only high quality distilled water and avoid purified or filtered water since they contain high amount of dissolved solids.
