3 Darrieus Wind Turbine Facts You’ll Want to Know

When it comes to green energy alternatives wind turbines are certainly up there with solar energy and hydropower generators as being one of the most attractive green energy options. In the paragraphs to follow I’m going to be sharing with you some Darrieus wind turbine facts you may not be aware of, including important distinctions between the popular and iconic propeller driven wind turbines and the somewhat mysterious Darrieus types. These vertical axis wind turbines (VAWT’s for short) can very easily be seen as a superior design, let’s take a look at exactly why that is.

Low Wind Efficiency

When considering which type of wind turbine to go for one obvious factor stands out and that’s efficiency. After all the whole point here is to generate as much electricity as possible and remarkably this is where the Darrieus type of wind turbine really shines. Typical propeller designs are optimised to function best when the wind direction is headed straight into the front of the propeller which means when the wind changes (as it does on a moment by moment basis) the propeller stops spinning or at best severely reduces its rotation speed until the wind once again hits that sweet spot, which often must be achieved by rotating the propeller to face into the wind.

The Darrieus wind turbine however has a number of unique characteristics which enhance its performance, even under low wind conditions. The first being the unique shape of the aerofoil blades, curved out and shaped just like that of an aeroplanes wing, which when wind is applied produces high pressure on the inner side of the blade and low pressure on the outer side which then propels the blades and shaft around in a circular motion. The second and probably most distinctive attribute of this type of wind turbine is that while many have only two blades they typically can have three to four blades also, which means regardless of which direction the wind is blowing the shaft will continue to turn so long as there is wind. Even in low wind conditions the Darrieus wind turbines will keep spinning, only stopping when the wind comes to a complete stop.

Residential Friendliness

In a world where we’re trying to become more energy independent, sources of renewable green energy must also be practical… and practicality starts at home. When talking about wind turbines Darrieus versions are well known for being super quiet, which is crucial considering they are typically active day and night and I’m sure the last thing you want are complaining neighbours. So it’s important. They are well balanced and because they vibrate less they simply don’t produce as much noise.

A common problem often associated with wind turbines is that of birds flying into them and meeting their maker. This is obviously something to avoid and in this case, it’s something that can be avoid with great success. Many owners of Darrieus wind turbines report of having no such issues with birds flying into them, as opposed to propeller type wind turbines which have an unfortunate track record of causing harm to birds. This is likely due to the fact that because of the way the Darrieus turbines are designed, they appear like more of a solid object to birds and they tend to keep away from them.

Take Your Pick

There are a number of different designs which can be classed as Darrieus wind turbines. They share many similarities, however they also share key differences each with their own advantages. Giromills or H-bars as they are otherwise known are a “less efficient” design in normal conditions compared to the Darrieus designs, however often work well and in fact better in more turbulent wind conditions. They’re also more affordable.

Cycloturbines are an interesting creation as each blade is mounted so that it can rotate around its own vertical axis. This allows for the blades to be pitched for the optimum angle of attack which results in improved performance in a variety of wind conditions. The ability to adapt makes this design easily the most effective and most powerful Darrieus wind turbines available because it can produce more consistent torque. It’s also able to self start much easier because of the ability to pitch the blades. The only real downside is the complexity and added weight and cost of the pitch mechanism.

And finally the helical design is well known for it’s ability to spread the torque evenly over the entire rotation, which prevents what could otherwise be destructive pulsations, especially in turbulent conditions. These are often smaller units making them a great choice in residential areas.

All in all, nothing is perfect. Green energy has always been a challenging field, especially when competing with the dirty forms of energy we as a society have become so dependent upon. This of course is not a comprehensive list of pro’s and con’s, however it was never mean’t to be. It’s designed to get you thinking and considering Darrieus wind turbines as a viable green energy alternative.

The great thing about green energy technologies such as these (and a huge advantage over polluting alternatives) is that once you’ve set them up, they just run and run and run. You always need more coal, more oil, more “stuff” to break down, burn, etc.

But with wind power, it-just-works!

Introduction to Battery Chargers

Battery chargers vary a great deal in intelligence, the types of batteries they can charge, how they maintain batteries, and how long they take to charge. As batteries are such a big investment when it comes to off grid solar power systems, it’s important to get the right one for your off grid solar power system. 

A general rule of thumb is to charge a battery at about 10% of  its amp hour capacity. For example, and 80Ah deep cycle battery should be changed at a rate of about 8A.

Different types of batteries require different charging regimes. For example, SLA (sealed lead acid), AGM (absorbent glass matt) and gel batteries are traditionally charged at a lower voltage than flooded lead acid batteries. This varies depending on the manufacturer and you should always check what charging voltage is required before you buy batteries and a battery charger.

Types of battery chargers

A simple charger works by providing a constant DC power to the battery. A simple charger will not alter its output based on time or the charge on the battery. These type of battery chargers are usually cheap, but there is a trade-off in quality. Typically, a simple charger takes far longer to charge a battery, and a battery left in a simple charger for too long will be severely damaged by over-charging.

Timer based chargers operate much like a simple charger, but (as the name would suggest) they operate on a timer. The timing  would be set for a particular battery and then left. However, if batteries of lower capacity were charged they would be then overcharged and if batteries of higher capacity were charged they would be only partly charged. Timer based chargers also have the drawback that charging batteries that were not fully discharged, even if those batteries were of the correct capacity for the particular timed charger, would result in over-charging.

Battery charger output current depends upon the battery’s state. An intelligent charger may monitor the battery’s voltage, temperature and/or time under charge to determine the optimum charge current at that instant. Charging is terminated when a combination of the voltage, temperature and/or time indicates that the battery is fully charged. In a sense, the batteries tell the charger when they are full.

Some chargers use pulse technology or pulse width modulationin which a pulse is fed to the battery. This DC pulse has a strictly controlled rise time, shape, pulse width, frequency and amplitude. This technology is said to work with any size, voltage, capacity or chemistry of batteries, including automotive and valve-regulated batteries. Most good quality chargers and charge controller use this kind of technology.

Selecting the right charger

As with any component of a solar power system, it’s always best to consult with a battery expert first before purchasing to ensure you’re getting a charger suited to your particular set up. While all chargers work well off a mains power supply, you’ll likely be using yours in conjunction with a generator, so check that the charger you’re interested in is up to the task – some just refuse to function properly in this application.

What Radiant Energy Is and How You Can Use It to Power Your Home

Radiant energy is a wonderful source of power. We use it in our daily lives from listening to the radio and talking on our cellphones and much more. It envelops the atmosphere from day to day, year to year, 24/7. The supply of this energy never runs out and only gets bigger every year.

But what is radiant energy, anyway? Radiant energy is simply the forms of electromagnetic waves that collide in our electro sphere. What does that mean? Well it’s quite simple really. They are waves of energy and radiation that we cannot see with our eyes. Because they have different wavelengths there are different types of waves. For example. one such wave could be an x-ray. You probably have been to a hospital sometime in your life. If you have had a broken bone in your body you probably would have had an x-ray checkup with a radiologist.

If radiant energy is common, why don’t we use it? But we already do. Like I said before we use it to power our cellphone signals. our radio towers, and even our microwaves. However when I refer to this energy, I am referring to a different use of this energy. Instead of using it to directly power certain appliances we can use an energy generator to power our appliances. That’s because radiant energy is in essence a form of energy. By converting that energy (in the form of waves) to electricity, much like solar panels do, we can power our homes with it.

How can we use radiant energy to power our homes? In order to convert the energy into a usable form of electricity we will need a specific generator than can use this power. They are called radiant energy generators. These generators sort through the different waves of energy in the air, or more precisely the atmosphere, and convert it into electricity. Some waves cannot be converted and that’s why it sorts through the different frequencies that are compatible.

Where can we get such a thing? The easiest place to get it would be from a company who specializes in these kind of plans. Of course they would only be large-scale archetypes and not actual working models. Currently energy efficiency labs are only focusing their r&d (research and development) in large-scale versions of radiant energy generators. It’s mainly because these small generators are hard to upscale after a few upgrades. Small-scale radiant energy generators are much easier to build though and also happen to be affordable, if you can find the schematics for it. I have actually come across and interesting site that claims to have plans for a radiant energy generator. I was a bit skeptical though, but I decided to check it out. The plans were called ” Sky 4 Energy “. I spent my spare time in the week building it and the results were fantastic. I would tell you more but I already wrote the results in my review site where I objectively reviewed several popular energy generator plans similar to this one.

Prepaid and Postpaid System for Electricity

Consumers of electricity these days now have the option on having their electricity put on prepaid or postpaid plans. Prepaid plan on electricity is where consumers deposit first or pay in advance to be able to use electricity while postpaid plan is when a consumer pays for his or her electricity after using it.

How does a prepaid electricity system work?

Mainly, consumers must first purchase a card that has special numbers on it that can be loaded by credits that will then enable them to use electricity, depending on the credits that was loaded. For them to use more electricity they can just simply load their accounts again and by loading their accounts regularly, they also eliminate the possibility of being disconnected from the electric company. In some places, loading an account directly is impossible, what must be done is for them to go to the electric company’s billing center and pay a cashier who will then load credits onto their accounts giving them the electricity supply that they can then use.

How does a postpaid electricity system work?

A postpaid electricity system is what is commonly used all over the world in terms of electricity usage and electrical bills. A meter is installed that will then measure the usage of electricity that has been used in a household or building. The consumers will then be billed on a monthly basis. If an instance like a consumer was not able to pay his or her bills, then that person will be disconnected from the system and will no longer be able to use electricity.

Advantages and disadvantages

Of course like any other system, there is always an advantage and a disadvantage. The advantage for having a prepaid system is that the consumers will have control as to when they would want to use electricity and will never have to pay late on bills. The disadvantage in using a prepaid system is that when a possibility like consumers having to forget to load their accounts, they will not have any electricity to use at home and that can be very inconvenient. While postpaid system however, guarantees that consumers always have electricity supplies except of course during blackouts.

And because of the meter that was installed and being used to measure the consumer’s electricity usage, personnel from the electric company will come on a regular basis to check the amount of electricity that the consumers have used thus eliminating the effort on checking their own meter reading. The disadvantage of postpaid systems is that it requires an expensive amount of deposit. When deciding to terminate a customer relationship from the electric company, the refund that the company will give back takes long enough.

Fossil Fuels and Classifications

FUELS & COMBUSTION

Fossil fuel-

· Fuel can be defined as a combustible substance which contains carbon as its main components, which gives large amount of heat on proper burning.

· Carbon can be used economically for domestic and industrial requirements.

· Common example involving wood, charcoal, coal, kerosene, petrol, diesel, producer gas, oil gas, etc.

· During combustion process of a fuel (like coal), the atoms of carbon, hydrogen, etc. combine with oxygen with the simultaneous release of heat at a speedy rate.

· This energy is released due to the “rearrangement of valence elections” in these atoms, resulting in the formation of new compounds like methane and water.

FUEL + OXYGEN —> PRODUCTS + HEAT.

· Coals and petroleum oils are the main source of the fuel; the available quantity of these sources is reduced day by day.

· Fossil fuels are composed by natural resources such as anaerobic decomposition of buried dead organisms.

· The age of the organisms and their resulting fossil fuels is more than millions of years.

· They are non-renewable resources because they take thousands of years to form, and reserves are being decomposed much faster than new ones are being made.

· Its uses and production raise environmental issue.

Classification:

1. Solid fuel

· Solid fuel is defined as raw materials which are used as a primary fuel to produce energy and provide heating.

· Common example under this category includes wood, charcoal, peat, coal, Hexamine fuel tablets, and pellets made from wood, wheat, rye and other grains.

· It also used in solid fuel rocket technology.

· For creating fire, it has been used.

· Coal is used for firing furnaces, to running steam engines.

· Steam locomotives engines are operated by using wood as fuel.

· In electricity generation, peat and coals are used.

· Due to unsafe levels of toxic emissions, use of some solid fuels is restricted or prohibited in some urban areas.

2. Liquid Fuel

· Liquid fuels are defined as combustible or energy-generating molecules which are used to produce mechanical energy.

· Fumes of these fuels are flammable instead of the fluid.

· Most liquid fuels which are used for various purpose in now days, are derived from petroleum.

Types of liquid fuel:

Gasoline

· It is a by-product of petroleum, contains carbon and hydrogen.

· Gasoline or petrol is produce by hydrocarbon molecules forming aliphatic compounds, or chains of carbons with hydrogen atoms attached.

· Engines that use unleaded gasoline releases fewer hydrocarbons, have fewer combustion chamber deposits, and provide a longer life for spark plugs, exhaust system and carburetors.

· It is generated by distillation of crude oil.

· The desirable liquid is taken out from the crude oil in refineries.

· For the formation of gasoline, petroleum must first be removed from crude oil.

· Gasoline itself is actually not burned, but the fumes it creates ignite.

Diesel fuel

· It is a mixture of aliphatic hydrocarbons extracted from petroleum.

· Diesel may cost less than gasoline; it costs less for production because the extraction processes used are simpler.

· It can hold dirt particles in suspension longer than gasoline because it is heavier and more viscous.

· Its efficiency varies with the type of engine.

· Use of a polluted fuel or an improper grade of fuel can cause hard starting, incomplete combustion, and a Smokey exhaust.

Kerosene

· Kerosene is defined as flammable hydrocarbon oil usually obtained by distillation of petroleum and used as a fuel, solvent, and thinner.

· It is sometimes used as an additive in diesel fuel to prevent gelling or waxing in cold temperatures.

· Heat of combustion of kerosene is similar to that of diesel

· It is generally used for heating and fueling vehicles.

3. Fuel gas

· Fuel gas can be referred to any of several gases burned to produce thermal energy.

Natural gas (methane) is the most common example of fuel gas, others include:

· Coal gas or Town gas

· Syngas

· Mond gas

· Propane

· Butane

· Regasified liquefied petroleum gas

· Wood gas

· Producer gas

· Water gas

· HCNG

Caring for Your Solar Landscape Lights

Solar landscape lights have become a popular trend for landscape designers and homeowners. With the popular “go green” campaign, pushed inadvertently by the recent economic crisis, people everywhere are looking for ways to save, no matter how small those ways might be. One of those ways is with solar landscape lights. Instead of garden lighting which would direct light upward and downward, costing more in energy and losing a good portion of the light to the sky, people are utilizing solar landscape lights which recharge in the sun and maintain a charge throughout the night.

There are solar landscape lights in every style and can match any taste. No matter the décor of your landscape, you can find solar lights to match. Above all, it is important that your solar landscape lights are enjoyed whilst illuminating your garden design and creativity. Once you have found the perfect solar landscape lights, the next step is learning how to keep them clean. Since they are outside your solar landscape lights will get dirty quickly especially if they are placed in a landscape bed or garden. If your solar landscape lights are covered in dirt or grime, it will detract from their ability to charge effectively while also detracting from the aesthetic appeal of your lights. It is important to avoid commercial cleaning products because they will damage the solar garden lights. The best way to clean them is to use a clean, damp cloth to wipe away the grime or dirt. Solar garden lights are water resistant, however they are not water proof so the lights should not be immersed in water. The water could get into the electrical conduits inside of the solar garden lights and damage the entire unit.

Another tip in terms of caring for your solar garden lights is to remove them at the end of the season. You do not want to leave them standing in winter seasons when your areas endures freezing temperatures. If the lights are left to freeze and then thaw, the lifespan of the material will be reduced. If they are left in colder temperatures with reduced daylight hours, the lifespan of the battery will decrease. If you want to winterize your lights, clean them with a damp cloth and then turn the switch to off. Remove the batteries from the lights and recharge them in a household battery recharger. You can then place a new battery in your solar garden lights when the spring season arrives, ensuring longer hours of illumination.

When spring time rolls around, it is best to place the solar garden lights in a protected area. Many people consider where they want to place their solar garden lights but they do not first consider the amount of sunlight they will receive during the daylight hours. Since the most common problem with solar garden lights is the lack of sunlight they receive you can avert this issue by ensuring that they are placed in direct sunlight. With this, the batteries should enjoy a one to two year lifespan.

Save a Watt, Save a Lot With Energy Efficient Lighting Solutions

We all know that energy efficient lightbulbs help to protect the environment, and over the course of a few years they can also help your bank balance too, however when seeking money saving solutions that offer to save us hundreds of pounds on our utility bills, the lights are usually the last thing on our minds.

We will happily fork out for solar panels and ways to heat the home economically but many of us consider the few pence we save on wattage with lightbulbs to be lower down on the priority list.

Not only this but many energy efficient lighting solutions aren’t really solutions at all, as we swap the sixty watts for a pearlescent twist of a bulb we feel as though we are being rationed on luminescence. The lights take an age to flicker to life and when they do we find that although the glow is flattering, its simply quite depressing.

It’s a Blinking Conspiracy!

There are conspiracy theories around the new laws that sweep the sixty watt sunshine from the shelves as radicals do believe the government are lulling us into a subdued state in order to diminish our resolve, yet for those of us who enjoy a little light in our lives there are energy efficient lighting solutions that don’t take the shine out of everyday living.

The solutions promise to light up your home, your office, your factory or workplace in the flick of a switch, in fact surveys were carried out and not one person could tell the difference. So luminous are these bulbs that it’s amazing that they save money, and a normal family of five could see savings of hundreds of pounds.

That’s not all, consider the cost of lighting a factory with fluorescent strip lights, where the cost mounts and mounts quicker than workers can pull the products from the line. These same energy saving solutions save these huge companies massive amounts mounting to thousands of pounds off their business electricity bill.

It’s Light Jim, But Not as We Know It!

Using LEDs these lighting solutions are well ahead of their time, as not only do they save up to 90% on energy they are also simple to maintain. The lifespan is on average six times longer than their dull counterparts and with no annoying humming, flickering or radiation; mental and physical health improves too.

Many worry about the radiation scare of the energy saving light bulbs on offer, as apparently radiation leaks if ever a crack forms in the bulb. Some also swear that this form of radioactivity also penetrates bodies when the bulb is fully intact. LED lights however do not emit any radiation at all, and they’re a lot brighter than the tiny bulbs we remember from our craft and design lessons at school. This advancement in modern technology allows up to 75000 hours of light, no mean feat as this is almost a decade of light!

If you’re serious about saving the environment, these will also ease your conscience, with less carbon emissions; your footprint will drastically reduce turning your home or business into a lean green lighting machine!

How Going Green Can Reduce Global Warming

There are many ways going green can reduce global warming. The first starting point is with using renewable energy sources. You can choose a variety of different systems today, and the competition is so fierce that prices for kits and materials are as low as ever. You can find photovoltaic cells extremely inexpensively, and if you buy in bulk the savings is even more substantial. You can purchase all the framework materials at many of your local hardware and home improvement outlets. You also have many choices, such as solar power, wind turbines, geothermal, hydroelectric, and even magnetic generators. The nice thing is that these can be used as independent systems, or can be combined for even more power output.

On a personal level, using renewable energy in your own home can reduce global warming. For one, these sources don’t use any fossil fuels, so they don’t produce any of the toxins that coal, natural gas and nuclear power plants produce and release in the atmosphere. Because these systems don’t use fossil fuels, they are completely renewable, and don’t take away precious natural resources. There is no need to worry about where the energy comes from, or the methods used to extract them, like you do with coal.

It’s also not just about using alternative energy power systems in your home. There are many other ways you can cut down on global warming at home. Recycling is probably one of the other biggest ways you can reduce your carbon impact on the Planet. Recycling aluminum, glass and plastic make it easier to reproduce more, and it can save half of the energy needed to make these from scratch. Recycling paper reduces the amount of trees being cut down for paper products, and allows them to do their job, removing harmful carbon dioxide from the air, and producing oxygen.

Going green also means conservation in the home as well. Even if you are not using renewable energy resources, there are many ways you can conserve energy and valuable resources. Changing to more fuel efficient appliances for one thing can help cut down on wasted energy. Using Energy Star appliances instead, switching over to inline water heaters, and waiting until evening to use your dishwasher, or clothes washer can save you money and energy. Cutting down on water usage, like switching over to low flow faucets and toilets, and fixing faucets that are dripping will help save water.

Cutting down on vehicle use can significantly decrease global warming as well. Using a bike, taking public transportation, and just walking reduces carbon emissions that all vehicles emit. Switching to hybrid vehicles also makes a big positive impact, and prices of these vehicles have come down significantly over the last few years, making them more affordable.

There are many other ways that going green can significantly reduce global warming. There are an abundance of websites available to show you what things you can do to help the environment. There are DIY solar, wind and magnetic energy power system kits to choose from as well. We all need to do our part, before we come to a point where there simply is no turning back.

Your Must Read Review of the Xantrex C35 Solar Charge Controller

I formerly used a 7 amp Sunforce charge controller that I bought from Northern Tool when I first stepped into the realm of Solar Power. It lasted for a couple of months and then died. Upon recommendations from friends I researched “Pulse Width Modulation” solar charge controllers only to find that I kept coming back to the Xantrex C35. At this point I was using an off the shelf battery charger from the big box store and I found out that using those will greatly reduce the life span of your batteries. I had 105 watts of solar panels and this gave me around 7 amps of charging current with plenty of wiggle room for future expansion. I took the plunge. Plunked down my money and have never looked back.

The “C” series charge controllers are the mainstay of the Xantrex charge controller line-up. The C35 charge controller is a solid state, microprocessor driven, solar battery charger that will handle up to 35 constant amps of input current no matter what the charging source. The C35 utilizes a “PWM” charging style. “PWM” is a 3 stage charging profile that provides greater longevity for your batteries than a normal off the shelf battery charger. The Bulk, Absorption, and Float modes are used to ensure that voltage and current settings equal the state of charge of the batteries. This means the quickest possible charging and an extended battery life that you will not get if you use your fathers old charger. With the cost of batteries today, anything that prolongs their life is worth the price. The controller is U.L Listed and comes with a 2 year manufacturer’s warranty.

The C35 solar charge controller is field adjustable for either 12 or 24 volt DC operation. It can be set up as a DC load controller or as DC Diversion mode. This mode would be used if you were using Micro-Hydroelectric power or Wind Power to generate your electricity. The Xantrex C35 charge controller has been my main source as a solar powered battery charger for over a year now with absolutely Zero issues or problems. Would I hesitate to buy another one? Absolutely not! This charge controller has been the most reliable product in my solar toolbox and I look forward to many more happy years with it. My system continues to grow and currently I have the original C35 and now have added another C40 to sit beside it.
