I am a proud and active small business owner. It had long been my dream to open up a restaurant of my own and, over ten years ago now, I finally made that dream a reality. It’s hard work, and a lot of it, but I really do love having something I’m passionate about be what makes me my living. Of course, I am constantly learning more about the restaurant business as well as small business ownership in general. A year ago, my industry mixer busted and I was left frantically searching for electric motor repair in time to still serve my customers.

It is certainly not uncommon for small business owners to be reliant upon motors and other machines to keep them afloat. If you want to be protected when disaster strikes, take a lesson from my own experience and find a repair company before something breaks down rather than after. I chose a local, knowledgeable and professional company to keep me up and running.

Preventative maintenance from the repair company of my choice has been another lifesaver. I haven’t always been like this, but nowadays I call my repair folks as soon as one of my machines starts acting or sounding funny. Rather than waiting for it to fully break down, I get the problem solved right then. Usually, all the fix requires is a tightened bolt here or there.

However, when the problem turns out to be more serious, my repair folks will remove and repair the motor for me and get it running right. This lets me decide when to get equipment repaired rather than waiting for when something breaks down, often at the least opportune moment possible. Once, I was getting ready for the Saturday breakfast rush and my mixer stopped working.

I was panicked! Customers would be arriving as soon as I opened and yet I didn’t have the baked goods they came for. I simply can’t do by hand the work my industry sized mixer does. I was short on most menu items that morning.

Because of the experience, I’ve taken to making preventative maintenance on essential equipment a rule of business. If something needs a check up, I can wait until there’s a lull in business to send it off rather than having it breakdown right when I need it most. This makes it super easy to plan alternative techniques and menus to make do without the mixer.

When choosing what repair company I wanted to use for my small business machinery, I did quite a bit of research. First, I looked through the phone book and on the internet just to get an idea of what is out there. Because I’d never worked with motor repair companies before, I was surprised to see how many established companies existed even in my rural area.

I also asked other small business owners who they turn to when they need electric motor repair. With the recommendations I received, I looked deeper to check for technicians with certifications and an up to date knowledge of their field.

Despite being an important part of most everyone’s daily activities, the origins of electricity often seem like magic to most of us. There is in actually a vast complex network of grids which conducts power to our lights, our computers, and most everywhere else that needs electricity. Do you know what a fuse is? What about a switchgear or a generator? Let’s learn a bit more about how something as simple as turning a light on is possible thanks to power plants and countless other components.

The very first power system the world saw was created in England by two experimenting electricians. It was 1881 and their very primitive set up included two waterwheels producing enough alternative current, or AC power, to keep several dozen light bulbs illuminated at once.

The downside to this very simple design was that the alternate current wasn’t reliable enough to keep power to the lamps on a continual basis. The important thing was that the world could now see just what electrical power could accomplish. The bar was now set as both the United States and Europe began seriously devoting time to the concept.

In New York City at this time the inventor Thomas Edison devised a power station driven by steam. Truly the world’s first dependable power supply, this station would mark the beginning of the Edison Electric Light Company, and the increasing interest in electric lighting. Unlike the earlier water wheel power system, Edison’s power was generated by steam into a direct current, or DC.

It’s quaint to realize that electricity technology was so new back then that Edison could only provide to customers within a half mile range! Any farther than this and the power loss during transportation would make it impossible or unreasonable. Today, it is normal for people to live hundreds of miles away from the power plants that supply and regulate their electricity.

If we fast forward to the end of the 1800s, we find electricity being widely hailed as a healthy, growing field. More and more electrical companies were starting to spring into existence through Europe and the United States. Germany became the next country to begin development of electrical power. The existence of any sort of power grid or network arose as more of an afterthought than a plan.

Before this, remember, lighting was provided by the sun, candles and gas lamps only. The concept of electricity was new, unfamiliar and very exciting. No more gas fumes from lamps. No more candles dripping wax. The benefits were numerous and the public was excited about how the new technology could improve their lives.

Today, of course, few waterwheels are used in the grand scheme of powering the United States. Our power plants are complex and highly advanced combinations of fuses, circuit breakers and switchgear technology combined by engineers. Let all this knew information give you a moment of gratefulness the next time you switch on a light.

In any electrical system, there needs to be a set of fuses and switches that are available to shut down the electrical equipment in case of an emergency or for maintenance. This is clearly a necessary part of an electrical system because you have to be able to shut everything down from a remote location if there is an emergency. This set of switches is called switchgear.

Although switchgear panels have been in use since the early days of electricity, the technology has advanced substantially over the years. Until fairly recently, the switchgear systems required a manual shutdown, which involved sending someone to turn the switches off. This can be dangerous if there is an emergency underway, and the delay implied in that situation is unacceptable in an emergency.

Switchgear is designed with one of a variety of insulating materials that kills the current and shuts down the system. If you have a small system and a large open air area, you can use the open air as your insulating material; however, most systems are too large to use open air insulation. For quite some time oil was the insulator of choice. In this case, a stream of vaporized oil is shot through the electrical arc, severing the connection.

For some time oil was a common insulator, but the danger presented by an oil spill, especially given the proximity to electrical systems has led to the gradual move away from oil insulation in switchgear technology. Oil insulation works by shooting some vaporized oil through the electric arc to extinguish it. Again, this method is effective but is rarely implemented lately due to the risk of oil spills.

One of the most effective insulating materials is gas, although it is extremely expensive and therefore not suitable for all situations. In this situation, the circuit breaker uses magnetic fields to stretch the electrical arc and then the gas breaks the arc. You must use a specific insulating gas.

Another insulating method is vacuum insulation. In this situation, the vacuum insulation quenches the electric arc. This only works in medium voltage situations because there vacuum insulation is not strong enough or stable enough to handle higher voltage situations. The electric arc is compressed in this system as vacuum insulation requires very little stretching in order to extinguish the current.

Another option is a compressed air insulated system. In this system the air elongates the electrical arc until it is unable to sustain itself and extinguishes itself. This is a simple system and effective in many voltage arrangements. This is obviously not at all the same as the open air system discussed earlier.

Switchgear is a necessary safety device for any electrical system.

So, how much energy does a wind turbine produce? This question is very common as alternative power sources are still somewhat new. The answer can vary and will depend primarily on the wind turbine used and the weather conditions.

There is no limit to how little power can be generated from a wind turbine as these could easily be designed to generate ten kilo watts of power or so. This low level of power generation might fit perfectly for clients that are using their units for charging batteries. However, the vast majority are going to require much more power than this.

A wind turbine could easily be used to meet all the power requirements of a common household, maybe even with a little bit to spare. There are households that run entirely off of the use of a moderately sized wind turbine. A group of some of the larger units might be able to power up to several thousand houses.

The number one factor that is going to determine how much power a wind turbine is able to generate is going to obviously be the size. The larger units are naturally going to be capable of generating higher levels of output than the smallest ones. Most of the time when people see wind turbines they are seeing the mid to large-sized ones.

A lot of people do not understand that alternative energy devices typically are built into systems that come in two varieties. One variety has the use of a battery component that stores energy and might be more practical in a larger number of situations. There are some systems that offer no type of battery component so some of these systems might not be providing any power when there is a lack of wind.

Some people assume that the windiest areas might be perfectly capable of producing a higher amount of power however this is usually not the case because not all of the wind’s power is used. For such a device to work properly the air actually has to pass through the device in just the right way after striking the blades.

These units are just one of the alternative technologies that are being used to challenge some of the more traditional technologies. There will always be certain areas where a particular technology is preferred over another because of the environmental conditions. These units are often preferred over solar power in areas where the sun might not shine for entire days at a time.

So, how much energy does a wind turbine produce? As much energy as the user needs which means that a great deal of possible applications can be handled.

The use of wind power is among the most environmentally friendly ways of generating electricity. There are two types of wind turbines used in this form of alternative energy, known as horizontal axis and vertical axis. A turbine works by creating friction as its blades rotate. This is then converted into electricity by a generator.

As well as the large units used to provide electricity to an electrical grid, there are also smaller ones, which can be used at home. These are available as a freestanding tower unit or can be mounted onto a roof. This is an excellent way for people to reduce their energy bills as well as to do their bit for the environment. Any excess energy can be sold to an electrical grid in certain jurisdictions, providing an incentive for people to use cleaner energy.

The horizontal axis types are the most common and probably the most familiar to people. They have a propeller that rotates on a horizontal axis. As a winds speed is higher at altitude, the propeller is placed on a very high tower along with the generator. The propeller is movable so it is always facing the winds direction, and is mostly used in an area where the winds direction is fairly consistent.

Horizontal axis units produce more electricity than their vertical counterparts; this is due to their height and the access to high winds. However, they are harder to maintain and can be damaged if the winds are strong. Some people complain that they dominate the landscape too much, as they can be seen over long distances. However, there are a number of horizontal-type wind farms out at sea.

The vertical axis styles are not so commonly seen, they have vertical blades and the generator is at the bottom. As the air pushes against the arms, the whole unit rotates. These units are often put in locations where the direction of the air currents is less consistent. They are often mounted on top of buildings or where there is a wind tunnel, for example between two buildings.

Vertical axis turbines have two subtypes. These are called Darrieus and Savonius. The eggbeater-shaped Darrieus turbine produces more energy than its Savonius counterpart; however they require energy to begin rotating. The Darrieus models tend to be used where winds are less reliable. The Savonius models have two scoops on either side, which catch air currents, making the unit rotate. They do not produce as much electricity, but do not require any energy to get going. Savonius turbines are usually used where there are less turbulent winds.

A vertical axis type is cheaper to maintain than the horizontal type because the generator is located at the bottom of the unit and its main parts are lower to the ground. Also, due to its shape it does not require a mechanism to turn it towards the wind. These types of wind turbines produce less electricity and are not tall enough to take advantage of high air currents, although it can be used in urban areas and in places where it would not be possible to put a horizontal axis turbine. Vertical axis units can also be placed closer together so they do not require as much space.

Practically everybody knows what a wind turbine is and how they produce energy, but for those who don’t know I will explain. A normal wind turbine is a big tower that has blades connected to a rotor. Whenever the wind blows the turbine the blades make the rotor rotate and the movement of the rotor makes the generator within the turbine crank out power. Inside the electrical generator are many magnets and loads of copper wire, which produces electricity. It is a fairly straightforward process.

Naturally for the turbine to work there will have to be wind. The reason why turbines are built so tall is to take advantage of the more potent winds found at more significant altitudes. This height allows the rotor to obtain more exposure to the wind and therefore create a lot more electricity. All of this would not matter if there was no wind from the beginning. Just before an installation of turbines is built, detailed analysis of wind patterns for the intended site is reviewed. This tends to mean they are situated along coastlines where it is generally very windy. Of course, the wind can adjust its direction which poses another downside for wind turbines. To conform to varying wind directions, the turbines are made to continually face into the wind, irregardless of direction.

Because of their efficient design, turbines can produce a lot of power that can be implemented for domestic or conventional applications. When there may be no wind, a battery backup set up is used to satisfy electrical needs. While they can certainly produce a lot of electricity, they are not cheap at all and getting back your initial investment on one can take many years. Unlike various other green energy methods, wind turbines will consistently work 24/7, providing there’s wind. Wind turbines can produce as much power at night as during the day, reducing the battery storage demands in some cases. Another excellent thing about wind turbines is that they’re eco-friendly as they produce virtually no pollution. The conventional sources of hydro, such as nuclear reactors, create tremendous pollution that could be eliminated by turbines. Harnessing the power of the wind is utilizing a truly environmentally friendly resource. Hence there is always likely to be energy produced by the turbines.

Let’s consider exactly what some may describe as the cons of wind turbine produced electricity. They’re certainly not a pretty sight, specifically because they’re so big. When clustered in groups, such as the large commercial installations in coastal areas and even out at sea, exactly where there are high winds, they are not an attractive site. Noise pollution is an additional complaint due to the friction of the rotor against the shaft when it spins. Wildlife aficionados complain that birds and bats are destroyed by them. The spinning rotors disrupt the bats’ ability to avoid objects with their sonar readings. While these reports are rarely noted they do happen.

The overall benefits of wind turbines seem to provide more benefits than the disadvantages at this time. They can play a significant role in our future energy plans if they are utilized carefully.

Changing wind power into electricity is the reason for deploying wind turbines. If you imagine an old-fashion plane propeller posted on top of an extremely high tower, this is exactly the way wind turbines appear. Electricity is produced by the generator, housed inside the turbine casing. Whenever the rotor is turned by the wind, the motor inside generates power. As with many types of power generators, magnets as well as copper wires comprise the motor and create a charge any time the rotor spins.

Wind turbines, as the name suggests, need the wind to blow so it can function. Standard heights for wind turbines is usually at least 30 meters, thus tapping into more powerful winds present at that height. Since higher wind velocities exist at that altitude more electricity is generated via the turbines. Obviously there needs to be enough wind to turn the blades and generate electricity from the outset. Historical weather information is carefully analyzed to select sites that will supply sufficient wind to operate the turbines. Many coastal places are ideal locations due to reliable and usually steady winds.

While wind speed is the most vital variable to measure, wind direction may also have an impact on the performance of the installation. However the engineered design is extremely clever. Most modern wind turbines are constructed so that the rotor turns in the direction of the wind, enabling them to snag the wind from any direction. Enough electricity to meet the large needs of an entire household or even a city can be produced from a solitary turbine or more complex wind farms.

Unlike other green energy methods, wind turbines will continue to work 24/7, providing there is wind. Solar panels cannot operate in the dark while wind turbines can. With so much fear about pollution today, turbines are a great solution because they are so clean. This suggests that wind turbines do not contribute towards the effects of global warming because there are no fuels actually burned and no emissions being discharged into the atmosphere. Another advantage is that turbines are harvesting energy from a regularly renewing source. Thus there is always going to be energy generated by the turbines.

Though there are many advantages, there are a few drawbacks to wind power projects. When there’s no wind, backup systems are used to satisfy electrical needs. Another concern is the number of years needed for the installation expenses to be recovered in power savings. Many men and women don’t want to be observing a tall tower with a propeller at the top outside their window. Many governments choose to put wind turbines on coastal areas and out to sea due to the large amounts of wind in these particular areas, but many people complain saying that they tarnish the surroundings. They are also fairly noisy due to the rotor generating sound as it spins round and round.

While wind farms have great potential for humans, they can be dangerous to birds and bats. The reason stated for bats flying into wind turbines is that the movement in the air disrupts their capability to detect obstacles with their internal sonar systems. While these occurrences are rarely reported they do happen.

Thinking about the benefits and drawbacks of wind farm project, they have more going in their favor than not. Wind turbines offer remarkable promise for generating clean, sustainable, safe energy and most of the downsides are pretty minute in comparison.

Many folks are unsurprisingly interested in the concept of tapping into free wind power by building a DIY wind generator. Before getting started with such a project it is worthwhile taking some time to be knowledgeable about the fundamental concepts of wind power before making up your mind about building a wind generator. It can be slightly involved to run your appliances off the harvested electricity but the construction of a generator is comparatively easy.

Because the construction is not too difficult, some may find this idea more attractive than building their own solar panels. This might be because windmills have been around for hundreds of years. In comparison solar power is quite modern and uses modern materials and unfamiliar concepts.

A potential difficulty with using a DIY wind generator is that the wind is not always constant. The electrical energy you generate can be stored in batteries, but you need to make sure that you can divert excess power when the batteries are full, otherwise they can burn out. A really windy day can force a lot of air through your system and might just make too much of a good thing.

In comparison, if you are just using a windmill for pumping water, you can let any water just overspill. The blades can keep on turning and making the pump run and too much power and H2O is not a factor.

Storing energy for later utilisation is more complicated when you employ a DIY wind generator. If you want to make plans for dealing with excess power, you can install automatic switches for some of your appliances. What happens is that you set the system to automatically switch on an gadget like the TV whenever your storage batteries are full. You can also make a disconnect, either manual or automatic, to close off the storage batteries if they are completely charged. It won’t matter if the blades are spinning away if the electricity is not flowing into the storage units.

The point is not that it is impossible to use windy days to power your home, but that there is more to it than you may realize. The most beneficial way to deal with this matter is to sell your unwanted power back to the power company. For the minor inconvenience of staying joined to the power grid, you will be able to create some more income.

If you want some extra information on making a plan to get rid of spare power, you can easily find it on-line. It is just one more challenge for those who wish to save money and use eco-friendly engineering. When you take into account that you will be using electricity for many years to come, you will see that the minor effort of building a wind turbine will be repaid many times over.

A DIY wind generator may well be the solution to your power needs, as long as you make the system to fit what you want it to do.

Before you consider any plans for making a DIY wind generator, make sure you grab your copy of Paul Robertson’s practical FREE Report On DIY Energy Options, plus a load of other money-saving ideas.. Also published at DIY Wind Generator – How To Get Rid Of Excess Power.

Vertical Wind Generators – Sometimes a Better Choice than Horizontal

With the rising price of fuel oil, and the rising costs of energy in general, there is increasing demand for home generated power, be it from solar-electric, solar thermal heating, or wind generated power. Of those three options, wind generated power is by far and away the most mature option, with the best odds for getting a reasonable payback in a typical home owning time frame.

With wind power generators, there are two general types to consider: Horizontal blade generators, and vertical wind generators. Horizontal generators are the type most people associate with a windmill or wind generator – they have blades that rotate perpendicular to the ground, with the axis of rotation being horizontal. They have significant advantages in efficiency, but work best when put on a tower, where they can catch the upper contrail winds, and they’re more mechanically complex. On top of this, they’re also a hazard to birds, and can be quite noisy.

For rural applications, horizontal generators reign supreme. When attached to someone’s home for net metered power generation, they run afoul of local zoning ordinances and home owners associations, because, bluntly, there’s no real way to make a 35 tall wind turbine look like it’s part of a Victorian deco home plot. Couple this with dead birds, loud noises, and people afraid they’ll blow over in a storm, and there’s a lot of barriers to installation.

The best choice for a homeowner is a vertical wind generator, which rotates on a vertical axis. There are drawbacks – they’re about half as efficient as the more traditional wind turbine, and they may need a small “boost” from an electric motor to get their initial rotation going; their minimum threshold for usable wind is a bit lower.

On the other hand, vertical wind generators have the advantage of being suitable for a ground level installation. They can be put out in the middle of the back yard, or on top of the roof of your garage. They’re much quieter in general than horizontal generators, and because they operate at a lower altitude, they’re less likely to kill birds. They also don’t need a yaw element (the “tail” of a conventional turbine blade) to steer them into the wind direction, as they can generate energy from any wind direction the breeze is blowing in from.

Another benefit of vertical wind generators is the range of vendors supplying them; horizontal generators are good for industrial applications, but they’re often $12,000 or more to install. Vertical wind generators are often under $5,000. With most electrical prices set the way they are, a vertical wind generator can pay for itself in home use in around 20 to 25 years. (A horizontal generator will be more efficient, and generate power at a lower baseline wind speed, making its higher up front cost make more sense).

Vertical wind generators are also (generally) more aesthetic. They’re less likely to be noticed as being an odd addition than a 36′ tall tower would be. Some of the more aerodynamic ones tend to look like short rotating sculptures, and there are even bladeless or rotorless turbines.

The most common type of home deployed vertical wind generator is the Savonius type, which uses airfoils and wide variable pitch blades to generate power. Built more or less like large anemometers, they run into problems with generated drag; more efficient ones use variable formations on the blade to minimize drag when they’re being swing through the incoming breeze.

The other type of wind generator is the so-called ‘egg beater’ windmill – they can scale up to the full industrial size installation, though they’re also suitable for small home installations. They’re much more efficient, but also noisier, and a bit more effort is required to maintain them.

Depending on where you’re setting your vertical wind generator up, your local utility company may offer credits for doing so, and nearly 90% of the utility companies in the US offer some form of net metering, where excess electricity you produce from your vertical wind generator is sold back to them and credited against your bill. Look seriously into the options your utility company provides before investing in a vertical wind generator, and consider it an investment in cheaper power down the road.

Wind power has been a valuable tool throughout the history of civilization. We’ve used it to propel our boats across the oceans and to spin wind turbines to grind our grain. In the modern age we are using wind power to generate electricity.

Wind power systems work well in locations with wind speeds in excess of 7 mph. This wind should be available on a frequent basis. Wind turbines are somewhat of a specialty, however, since they can be used only in locations with constant patterns of winds. These patterns are often related to mountain Chinooks, coastal climates, and locations in the Great Plains under the influences of the jet stream.

Wind power systems are usually coupled to an AC or DC generator and battery bank, and may be outsourced to the electrical grid. Since wind speeds often change, then so too our wind turbine rotational speed will want to change. Wind turbines have an ideal operational speed based on their aerodynamics. Modern load control and variable pitch blade systems are often used to help maintain the turbines within this operating range.

Horizontal axis wind turbines are the most dominant design in the wind power market today. These are the traditional style of windmill with two to four blades facing head on into the wind stream. Sizes range from small home units that will generate a few kilowatts, on up to large industrial units in excess of 1 Megawatt.

Vertical axis wind turbines have seen limited time in the market place. They take on the flow tangentially and use a different style of blades. Historically, their design was compact and easy to install, but at the expense of some output and efficiency. They are nice for someone considering a smaller output roof mounted wind power unit, however very few designs are available on the market today. Some newer designs are under development, however, and so with some time market conditions may change.

Mathematically speaking, the amount of wind power we generate is proportional to the wind velocity cubed. And so once can imagine the difference between a 15 mph and 7 mph wind source can be huge. When installing our wind turbine systems, we should try and keep them at the highest elevation that is possible. This reduces the effects of trees, structures, and other land based obstructions on wind velocity.

An additional thing to keep in mind is too much wind. Extreme gusts and high velocities could overload the wind turbine, and so we must have a way to protect from this. Variable pitch (self adjusting) blades are helpful, but in the stronger storms we may have to decommission the turbine, lock down the rotor, and reorient to the lowest stress position.

The decision whether to use wind can be pretty easy. Just by experience, you should know your local wind patterns and couple of measurements should tell if you are in excess of 7 mph. In certain locations, wind power works nicely hybridized with solar panel installations.

Using the local wind patterns is an ancient practice for obtaining energy. If you have the right weather conditions, then wind power is a good choice for you. There will be some planning and forethought in the type of system you select. But once in place, you will have an energy source that is clean, reliable, and free for generations to come.
