Health Benefits of Natural Light

The obvious benefit of installing solar light tubes is the energy savings that result lowering your electrical bills; however another less hyped benefit is the natural light they bring into your home. Natural light is pleasing in general for most people but did you know that it is also beneficial to your health? Not only is natural sunlight an effective germ killer it is also linked to improving moods and assisting with curing some illnesses.

Sunlight can kill bacteria present in dust particles and other germs that could be spread around your family. It is the ultraviolet rays in sunlight that act as a natural antiseptic that will improve your home environment. To get the most out of the sun, hang blankets and quilts or other items outside in the sunshine for a few hours to kill any virus, bacteria or mold on them. Killing germs is only one health benefit that natural light offers but is a great start to keeping your family safe and healthy.

Did you know that a lack of exposure to natural light has been linked to disorders such as: seasonal affective disorder, rickets, depression, and osteoporosis? Our bodies need natural light to make vitamin D which helps with some of those disorders, but sunlight also helps balance hormones and encourages healthy blood circulation to improve overall health. There are other ways to get vitamin D such as food, but sunlight is the best source for your body to create it naturally. Another benefit of daily exposure to sunlight is the increase of white blood cells in your blood which enhances your immune system and also improves digestion and metabolism.

We are not saying that you need to run outside and lay in the sun all day. There are downsides to overexposure to the sun as well. Skin cancer can be caused by overexposure to the sun so you must be careful to protect yourself while getting your daily sun. Spending just 10 minutes a day in natural sunlight is enough for your body to regulate itself and get all the benefits from the sunlight it can! But you can have natural light in your home without the sunburn just by installing solar light tubes. All the benefits and none of the downside!

The Amazing "Allure of the Seas" Has Some Green Credentials

The Allure of the Seas is Royal Caribbean’s newest cruise ship, which now boasts the largest cruise ship ever built claiming to be bigger than her sister ship the Oasis of the Seas by 2 inches and also lighter by 200 ton’s.

This remarkable ship has many green features aboard to help her underway one of them is the 1400sq meters of solar panels on her top deck, these solar panels provide enough electricity to light up 200 staterooms out of the 2300 rooms on board when the sun shines, when the sun stops shinning the power comes from one of the powerful six diesel engines which in total produce 135,000 horse power and burn an amazing 1100 tons of fuel per 7 day cruise, which works out at 130 gallons per mile.

The ship’s water comes from the sea and to remove the salt a desalination plant is based in the lower decks, the water is desalinised by 2 reverse osmosis plants and four evaporators producing 1 million gallons of drinkable water a day this water is used for all the ships on board taps, toilets, washing and swimming pools.

The waste water goes through a sewerage treatment plant and when expelled into the sea it is as pure as clean water. Everything on board the ship that is discarded is recycled, bottles are collected in massive bags to be recycled at port, all plastics are separated and kept they even have a special place for small batteries that have been used by the 5400 passengers that are on the ship, which also now get recycled.

This ship is amazing with 7 different zones to entertain you which never seems to stop, it has so many different places to eat and drink you won’t fail to put on a few pounds, the quality of the food will amaze you and if you have a sweet tooth there are 25 pastry chefs baking all the time. A week’s cruise on this ship will leave you satisfied, exhausted and full of really good memories.

3 Facts About Electromagnetic Energy – Best Alternative Energy Source for Our Energy Crisis?

When you first heard of electromagnetic energy you possibly had no idea what it even was. Maybe it has something to do with magnets? Maybe even a collection of giant Magnets! Jk But if you had any idea on the true understanding of this energy source you would be amazed.

Fact #1: Electromagnetic radiation causes both electric and magnetic fields at all times. So this is how we begin to understand it true power.

Fact #2: It was first recorded by Hans Christian Orsted, a Danish physicist and chemist. He discovered it by using his compass and then turning on the battery!

Fact #3: There are 9 types of electromagnetic waves which produce energy and can be used for different purpose’s other then power your home.

I’m telling you these Facts because I want to let you know that this is real and not something make believe or some gimmick. This is a awesome energy source that has been purposely surpassed by unknown people, but their are theories behind it. This source has been used before by civilization and was able to give power for them as well. As to what they were powering scientist are still debating to this day but we do know for a fact that it has been used.

How could such a cheap and limitless power supply just be forgotten and vanish, you ask? Well just think about that for a second and you should realize that the energy business is a trillion dollar a year business! Now that’s a lot of money to risk if the masses discover a free way to power their homes,cars, or anything else that might need energy.

Slowly but surly we as a great country are coming to terms with our energy crisis. Yet is the government moving to slow to actually turn it around so millions of Americans will not have to go cold,starve, and lastly die because of not enough power to go around. You may be thinking that can’t happen in the USA but you are dead wrong my friend. Recently in California that was a blackout that lasted weeks because of power outages caused by not enough supply. I could go on and on with different instances of energy shortages being a real and scary problem for states, countries, and even The US of A.

How well do you feel right now that if the power to your house would be shut off, you could survive? That your groceries would last, your lights could turn back on, or how long could you keep warm in the winter? Can you really say right now that life would be fine and dandy for you. If so great job and keep up the good work. But if not? Join the millions of others whose lives depend on our power being provided for us, at a steep, growing cost, but nonetheless.

Prepare now while we still can, because who can honestly say what will come tomorrow or the next day. No one that who. So instead of waiting around for our government or others to fix this growing problem lets take charge ourselves! Become independent and live freely off the grid once and for all.

5 Hospitality Outdoor Furniture Trends for 2017

Hotels, restaurants and resorts always look to offer the best experience for their guests by following the latest trends. In the beginning of this year, you should consider modernizing your outdoors by building fashionable and inviting areas. So what are the hospitality outdoor furniture trends for 2017 that will make you look fresh to improve your business’s image?

Trend 1: Go green and/or blue

In the hospitality industry, colors have a psychological effect on people that can make their stay unforgettable… or not. So when planning your outdoor areas, be picky in choosing colors. According to the psychology of colors study, blue, green, yellow, red, and purple generate positive vibes. But which colors are trending in 2017? This year is the year of the blue and green derivatives like aqua, sea foam, drab green. These 2 main colors represent serenity and nature respectively. Therefore, having them part of your outdoor furniture sets, will improve the guests’ state of mind, and keep the garden or patio fresh.

Trend 2: Minimize maintenance efforts with aluminum

For outdoor spaces, one of the trends was and will probably always be to have maintenance-free furniture. Therefore, picking aluminum outdoor furniture will be the right choice to offer comfortable outdoor experience and have products that require minimum maintenance. In addition, aluminum is known to be a light material compared to what it offers in strength: it is weather and rust resistant, which means that your hospitality outdoor furniture sets will live longer.

Trend 3: Combine different materials & styles

Many hotels and restaurants stick with a single theme using only one outdoor furniture style, but 2017 suggests to mix and match designs and materials. For example, if you aren’t able to decide whether to have aluminum or rattan outdoor furniture, well just pick both. Also, for spacious areas, combine several outdoor furniture collections within the same space. However, for this tactic to be successful, the two collections must go well with each other. Customized garden and patio furniture can also be an option to ensure good harmony between the different sets.

Trend 4: Create unique ambiance with solar lighting

In 2017, get rid of wires and complicated installations with the use of outdoor solar lighting, which rely simply on solar energy to recharge their batteries. Outdoor solar lights save you the trouble of finding professionals who will create a mess to install wired lamps. In addition, placing outdoor solar lighting forms a unique ambiance in your outdoor space especially if you go creative by building innovative patterns.

Trend 5: Indoors and outdoors go together

Last but not least, outdoor furniture can be used on the inside just like on the outside. Therefore, removing the boundaries between outdoors and indoors to mix up the two spaces can be a great option, of course, if done in a smart way. Opening the indoors to the outdoors gives you additional space and creates total conformity.

In conclusion, applying these trends is a tricky task that requires professionals in order to optimize your outdoors. So contact a hospitality outdoor furniture supplier that will furnish your gardens and patios in the best way possible, according to your needs.

The Stirling Engine

A ‘Stirling Engine’ is in the family of heat engines. It is a closed cycle regenerative hot air (or other permanent gas) engine.. Closed cycle means that there is a fixed volume of the ‘working fluid’ in the system. There is no intake, there is no exhaust.

The Stirling engine was first patented in 1816 by Dr. Robert Stirling. The original patent focused more on ‘The Economizer’ which was a heat exchange unit that saw primary interest for use as the first incarnation of the solar water heater.

Originally the Stirling engine was developed by Robert Stirling and his brother James. It resulted in many patents and the first Sterling in commercial use was used to pump water in a quarry in 1818. After more development many patents for various improvements, including pressurization, which directly affected the amount of work or force the engine could produce, came about in 1845. By this time, the power output of this engine had been brought up to the level that it could drive all the machinery at a Dundee iron foundry.

The engine was promoted as being very fuel conserving and was pushed to be a safer alternative to steam engines of the time that had many deadly incidents involve exploding boilers. However because of the heat required and the level of exchange required, coupled with the materials of the day, the Stirling engine could never really give the steam engine serious competition, and by the late 1930’s the Stirling was all but forgotten in mainstream science and industry and only represented in odd toys and small ventilation fans.

Around this time, Philips, the large electrical and electronic manufacturer was seeing to expand its market for radio sets into areas where a power source or supply of batteries was considered unstable. Philips further developed the Stirling engine through World War II and really only achieved commercial success with the ‘reversed Stirling engine’ cryocooler. However Philips did take out quite a few patents and gain a large amount of information about the Stirling engine.

Since the Stirling engine is a closed cycle, it contains a fixed mass of gas called the “working fluid”, most commonly air, hydrogen or helium. In normal operation, the engine is sealed and no gas enters or leaves the engine. No valves are required, unlike other types of piston engines. The Stirling engine, like most heat-engines, cycles through four main processes: cooling, compression, heating and expansion. This is accomplished by moving the gas back and forth between hot and cold heat exchangers. The hot heat exchanger is in thermal contact with an external heat source, e.g. a fuel burner, and the cold heat exchanger being in thermal contact with an external heat sink, e.g. air fins. A change in gas temperature will cause a corresponding change in gas pressure, while the motion of the piston causes the gas to be alternately expanded and compressed.

The gas follows the behavior described by the gas laws which describe how a gas’s pressure, temperature and volume are related. When the gas is heated, because it is in a sealed chamber, the pressure rises and this then acts on the power piston to produce a power stroke. When the gas is cooled the pressure drops and this means that less work needs to be done by the piston to compress the gas on the return stroke, thus yielding a net power output.

When one side of the piston is open to the atmosphere, the operation is slightly different. As the sealed volume of working gas comes in contact with the hot side, it expands, doing work on both the piston and on the atmosphere. When the working gas contacts the cold side, the atmosphere does work on the gas and “compresses” it. Atmospheric pressure, which is greater than the cooled working gas, pushes on the piston.

To summarize, the Stirling engine uses the temperature difference between its hot end and cold end to establish a cycle of a fixed mass of gas expanding and contracting within the engine, thus converting thermal energy into mechanical power. The greater the temperature difference between the hot and cold sources, the greater the potential Carnot cycle efficiency.

Pros and Cons of Stirling Engines


  • They can run directly on any available heat source, not just one produced by combustion, so they can be employed to run on heat from solar, geothermal, biological, nuclear sources or waste heat from any industrial process.

  • A continuous combustion process can be used to supply heat, so most types of emissions can be greatly reduced.

  • Most types of Stirling engines have the bearing and seals on the cool side of the engine; consequently, they require less lubricant and last significantly longer between overhauls than other reciprocating engine types.

  • The engine mechanisms are in some ways simpler than other types of reciprocating engine types, i.e. no valves are needed, and the fuel burner system can be relatively simple.

  • A Stirling engine uses a single-phase working fluid which maintains an internal pressure close to the design pressure, and thus for a properly designed system the risk of explosion is relatively low. In comparison, a steam engine uses a two-phase gas/liquid working fluid, so a faulty relief valve can cause an over-pressure condition and a potentially dangerous explosion.

  • In some cases, low operating pressure allows the use of lightweight cylinders.

  • They can be built to run very quietly and without an air supply, for air-independent propulsion use in submarines or in space.

  • They start easily (albeit slowly, after a warm-up period) and run more efficiently in cold weather, in contrast to the internal combustion which starts quickly in warm weather, but not in cold weather.

  • A Stirling engine used for pumping water can be configured so that the pumped water cools the compression space. This is, of course, most effective when pumping cold water.

  • They are extremely flexible. They can be used as CHP (Combined Heat and Power) in the winter and as coolers in summers.

  • Waste heat is relatively easily harvested (compared to waste heat from an internal combustion engine) making Stirling engines useful for dual-output heat and power systems


Power and torque issues

  • Stirling engines, especially those that run on small temperature differentials, are quite large for the amount of power that they produce (i.e. they have low specific power). This is primarily due to the low heat transfer coefficient of gaseous convection which limits the heat flux that can be attained in an internal heat exchanger to about 4 – 20 W/(m*K). This makes it very challenging for the engine designer to transfer heat into and out of the working gas. Increasing the temperature differential and/or pressure allows Stirling engines to produce more power, assuming the heat exchangers are designed for the increased heat load, and can deliver the convected heat flux necessary.

  • A Stirling engine cannot start instantly; it literally needs to “warm up”. This is true of all external combustion engines, but the warm up time may be shorter for Stirlings than for others of this type such as steam engines. Stirling engines are best used as constant speed engines.

  • Power output of a Stirling tends to be constant and to adjust it can sometimes require careful design and additional mechanisms. Typically, changes in output are achieved by varying the displacement of the engine (often through use of a swashplate crankshaft arrangement), or by changing the quantity of working fluid, or by altering the piston/displacer phase angle, or in some cases simply by altering the engine load. This property is less of a drawback in hybrid electric propulsion or “base load” utility generation where constant power output is actually desirable.

Gas Choice Issues

  • Hydrogen’s low viscosity, high thermal conductivity and specific heat make it the most efficient working gas, in terms of thermodynamics and fluid dynamics, to use in a Stirling engine. However, given the high diffusion rate associated with this low molecular weight gas, hydrogen will leak through solid metal, thus it is very difficult to maintain pressure inside the engine for any length of time without replacement of the gas. Typically, auxiliary systems need to be added to maintain the proper quantity of working fluid. These systems can be a gas storage bottle or a gas generator. Hydrogen can be generated either by electrolysis of water, or by the reaction of acid on metal. Hydrogen can also cause the embrittlement of metals. Hydrogen is also a very flammable gas, while helium is inert.

  • Most technically advanced Stirling engines, like those developed for United States government labs, use helium as the working gas, because it functions close to the efficiency and power density of hydrogen with fewer of the material containment issues. Helium is relatively expensive, and must be supplied by bottled gas. One test showed hydrogen to be 5% absolutely (24% relatively) more efficient than helium in the GPU-3 Stirling engine.[14]

  • Some engines use air or nitrogen as the working fluid. These gases are less thermodynamically efficient but they minimize the problems of gas containment and supply. The use of Compressed air in contact with flammable materials or substances such as lubricating oil, introduces an explosion hazard, because compressed air contains a high partial pressure of oxygen. However, oxygen can be removed from air through an oxidation reaction, or bottled nitrogen can be used.

Size and Cost Issues

  • Stirling engine designs require heat exchangers for heat input and for heat output, and these must contain the pressure of the working fluid, where the pressure is proportional to the engine power output. In addition, the expansion-side heat exchanger is often at very high temperature, so the materials must resist the corrosive effects of the heat source, and have low creep (deformation). Typically these material requirements substantially increase the cost of the engine. The materials and assembly costs for a high temperature heat exchanger typically accounts for 40% of the total engine cost. (Hargraves)

  • All thermodynamic cycles require large temperature differentials for efficient operation; however, in an external combustion engine, the heater temperature always equals or exceeds the expansion temperature. This means that the metallurgical requirements for the heater material are very demanding. This is similar to a Gas turbine, but is in contrast to a Otto engine or Diesel engine, where the expansion temperature can far exceed the metallurgical limit of the engine materials, because the input heat-source is not conducted through the engine; so the engine materials operate closer to the average temperature of the working gas.

  • Dissipation of waste heat is especially complicated because the coolant temperature is kept as low as possible to maximize thermal efficiency. This increases the size of the radiators, which can make packaging difficult. Along with materials cost, this has been one of the factors limiting the adoption of Stirling engines as automotive prime movers. However, for other applications high power density is not required, such as Ship propulsion, and stationary microgeneration systems using combined heat and power (CHP).[13]

    There are many possible uses for the Stirling design. More research and devolopment will help move the technology along.

How to Find a Free Deep Cycle Battery

Maybe you are looking for a set of deep cycle batteries to replace your old ones. Maybe you want to find a free deep cycle battery to try desulfating it so it is near new and then try to sell it. Some people are even getting a large deep cycle battery and removing all the good cells so they can sell them for renewable energy systems.

A home renewable energy system using wind or solar needs anywhere from 12 volts to 48 volts. Each cell from a deep cycle battery is about 2 volts, so it takes 6 cells for every 12 volt section. If you were to buy these cells new, then they cost between $300 – $600 each. A small 12 volt 650 amp hour battery setup would cost about $1,800 for the forklift battery cells. You could use golf cart batteries at about $80 each and 220 amp hours each. It would take 6 of them to do it and it would cost about $500.

Here is the kicker, though. A deep cycle battery cell from a fork lift battery lasts about 4 times as long as a golf cart battery. You could refurbish the cells out of the forklift battery and sell them for $100 each. They would easily last twice as long (or more) as the golf cart batteries and you could make a handsome profit for doing it.

My first pair of forklift batteries that I got for free happened to be Yuasa batteries, but all kinds are available. What I discovered is that usually most cells in the battery are still pretty good. Usually it is one or two bad cells. Most places just have their batteries picked up for recycling when the battery doesn’t make it though a 8 hour shift. These two batteries to the left had all good cells except 3 of them. There are 12 cells in each (these are 24 volt, 700 amphour), so that gives me 21 good cells.

So, if you’re selling these cells, you can make up to $2,100 profit. If you keep them for your own use (which is what I did), then you could make 3 banks of 12 volts at 600 amp hours each, or 12 volts at 1800 amp hours total. I say 600 amp hours instead of 700 because even after checking fluid levels and using my homemade desulfator, the amp hour capacity never gets up to brand new levels. But you can usually get 70% to 90% capacity, especially if you remove the bad cells. In the above example, you will use 18 of the cells total, leaving 3 good ones. You will probably have to just recycle those last 3 cells.

To get the batteries free, just call around to anyplace with a warehouse that uses forklifts. The first two in the picture above were picked up at the local post office main hub. You could just go through the yellow pages. Ask if they use electric forklifts, if so, do they plan on replacing their batteries in the near future. If you have a pickup truck, I would stick with the 12 or 24 volt ones. You can tell them that you can take them off their hands for free and that you will sign any environmental forms that they require.

There is another way to get forklift batteries but it costs a little money. Just look in the phone book and find the local forklift company. Almost all of them sell new batteries and deliver them as well. But they will also come and pickup old forklift batteries to recycle. They always have several sitting around. On Vancouver Island in Canada, the local company gets about 3 cents per pound from the local recycler. I can go to the forklift company and pick the best of the used ones and pay by the pound. A 24 volt like the one above weighs about 1,100 pounds or so. I can move those with a engine hoist and my V6 nissan pickup. Any bigger and you need other arrangements. They will also deliver the batteries to my home and plop them wherever I like. At 3 cents a pound, I could pay $66 for the two batteries in the above picture. Then they would charge about $70 per hour for the delivery. Let’s say, worse case, it cost 2 hours in labor, that is $206 for both batteries. If I sell individual cells in 12 volt groups, then I could sell 18 of them (3 cells were bad) and make $1,800. That gives me $1,600 profit. Not bad.

Advantages of a Perpetual Motion Machine

As the name may suggest, a perpetual motion machine is a device used to provide cost free energy and if used well, it can be available for all human beings. Well, to begin with, it’s important to understand that it’s very difficult to understand, rather to conceptualize a perpetual motion machine because it can take decades to create it. Still on point, there are very many contradicting theories as to how one can come up with a perpetual motion machine because in real sense, it’s very difficult, near impossible. However, thanks to advancement in technology and various scientific breakthroughs such as using magnets as the main material for this machine, people have started conceptualizing the idea in their minds.

There are numerous advantages of a perpetual motion machine in any given home. First off, although it’s not particularly visually appealing hence cannot be perceived as an aesthetic value in a home, it can still be used as a decoration and a source of pride for many, thanks to its design. It would be a source of pride as homeowners will be able to display their scientific knowledge and provide a sense of speculation to the visitors who know nothing about its functioning. It would be a piece of technology that will provide endless hours of conversation as the homeowner tries to explain the mechanism behind it, trying to explain the endless continuous motion. The main merit however that a perpetual motion machine provides lies primarily in the idea that it possesses a life changing functionality and not necessarily in its aesthetic or decorative aspect, although they cannot go unmentioned.

As a source of power in the house, its long term advantages are numerous particularly when it’s full potential is utilized well in a way that will emit even a portion of its real potential. However, the device has been an object of a lot of research as well as a source of controversy as to whether or not there is a possibility to come up with such a machine. But with the tangible evidence available at hand, it’s believed that a perpetual motion machine is certainly able to be used as an alternative source of power just like a wind energy thermal, a solar energy and various other alternative energies that the human species currently utilizes. With the current findings at hand, it’s believed that this type of alternative energy will be the cheapest source of energy when one factors in the cost of having it and the amount of work required to maintain it properly.

A perpetual motion machine is said to emit energy at nearly no cost at all. In other words, scientists are saying that this source of power will be affordable to many and one wouldn’t be required to invest a lot of money to get energy from it. While a few decades ago this technology was just a legend, thanks to the efforts of scientists and advancement in technology, the legend is no more a legend but a reality. Magnets have been used to make this legend a reality, while the current technology provides the backup necessary to turn the motion created into usable energy. As per the look of things, a perpetual motion machine is arguably the best technological breakthrough in regards to alternative energy in the current generation, all with the aim of making life easier and simpler.

No Deposit Texas Electric Service

A few electricity providers offer some alternative ways for low or no credit Texas energy consumers to have their electric service turned on without having to fork over the equivalent of 1 months rent for many of these Texas electricity customers. You will hear three different options when it comes to low or no deposit electric service. These options are post paid, no deposit guaranteed, and prepaid electricity service. The post paid energy service is what most people have. You simply are billed for the electricity service you used the previous month and you pay that amount. The problem is if you have bad credit most electricity companies in Texas are going to want a deposit.

Post paid electricity service is the ideal situation because you get billed for your usage after you have used it and you pay on the designated due date. This gives you time to read your bill and study how much energy you have used. You can then pay your bill online or by mail and maybe work on using less next month. The post paid electric service plans are usually cheaper then prepaid electric service. Many post paid plans available are fixed rates. These rates have been locked in for a 6 month, 1 year or 2 year electricity price. When signing up on a fixed rate you know exactly what you will be charged for electric service each and every month because the price does not change. The problem with trying to get on a fixed rate on a post paid service is that most providers will need a deposit if you have no credit or just bad credit. Many consumers have to skip this choice because the deposit amount is way outside what they can afford to pay.

There is another Texas electricity service choice called prepaid electricity. This type of service requires the Texas electric provider to come out to your home or apartment premises and install their own meter. This electricity meter allows you to prepay for electric service in advance. The main issue with prepaid electricity service in Texas is that many customers have complained that their electric service was cut off prematurely for being a little late on prepaying for their service. The Texas government requires that Texas electricity companies give the energy consumer fair warning before turning off their electric service but many consumers have complained that this is not what happens. The PUCT is supposed to fine the energy companies that break the rules but many consumers do not file the appropriate evidence that proves to the state that the Texas electricity company is not following the consumer protection laws. It is up to the consumer that was wronged to call the Public Utility Commission of Texas and explain what the Texas energy company has done to them in order for the state to take appropriate action.

The final Texas electricity service choice for low income or no credit customers is the no deposit guaranteed option. For those Texas energy consumers that have had their credit dinged by some late payments or a credit card that was charged off there is still an option for them. The no deposit guaranteed choice requires that the Texas energy consumer have a valid credit card. As long as a valid credit card is available there is a second chance for someone who needs to get Texas electric service turned on right away without having to worry about how they are going to come up with $200 – $1000 for a deposit. The way the no deposit plan works is the consumer pays a slightly higher electricity service rate the first 3 months they are with the no deposit Texas electric company. After the customer has paid on time the first 3 months the electric company will proactively lower the energy price to the lowest available electric rate they offer in Texas. This gives the no credit or bad credit customer a second chance of reestablishing themselves as a responsible customer who pays their bill on time. Instead of penalizing the customer for their mistakes in the past this company rewards the customer provided they pay their bill on time the first 3 months.

When choosing between post paid, prepaid and no deposit guaranteed electricity service in Texas there are only a few things to consider. The decision is a no-brainer for most people in a bad or no credit situation because most people want as little headache with their energy company as possible while still being given the chance to sign up for affordable energy service. Prepaid electricity is not the right choice for most people because the rate is usually much higher then other electric companies and the track record of these energy companies turning off electric service prematurely is pretty high. Post paid electricity service is not an option for most bad credit risk customers because they would have to come up with a very high deposit amount just to get electric service turned on in their name. No deposit guaranteed Texas electricity service becomes the best option for someone looking to sign up and order electric service in their name and completely avoid the high deposit scenario. The electricity service gets turned on fast and the headaches associated with shopping for an electric provider that will not charge a deposit are over. No Deposit Texas Electricity service is considered post paid electricity but without the need for a deposit. For most bad or no credit customers in Texas this represents the best possible option until their credit improves. Since a valid credit card is required some bad credit customers who do not have a credit card must sign up on a prepaid electric service plan because there are no other options then this if the customers credit is bad, they have no credit card, and they cannot afford to pay a deposit.

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!
