Before Buying Kitchen Sinks

Before choosing and buying a kitchen sink, these are some of the basic things you should know. Kitchen sinks have three major designs: the single bowl, the double bowl and the triple bowl sink. The names of the designs indicate how many sink bowls they have. The double bowl, which is said to be the most common, may have different-sized bowls or identical-sized ones. The double bowl design allows you to do two things at once. A sponge can be placed in the third bowl in the triple bowl design.

When considering which form your kitchen sink should be, consider the space allotted for it. If it is not very big, consider using the single bowl since a double or triple bowl design may not allow for a large container to fit. The depth of the bowl is also important. Deeper sinks lessen splashes but it may increase the need for bending over the sink. Also, take into account the under-counter space when determining the proper bowl depth.

Another aspect of kitchen sink design is mounting. With a top-mount sink, a hole is cut into the countertop and the sink is placed in it, with its edges resting on the countertop. An under-mount sink, on the other hand, is attached to the countertop from below. In contrast to the top-mount sink, the edges of the countertop surrounding the sink must be cleanly cut since they are visible. Sealants are also used to ensure that under-mount set-up is watertight. Another kind of mount is the apron kitchen sink. It is so called because it has an "apron" that hangs over the side of the countertop where the sink is perched.

Various materials can be used to make kitchen sinks. One of the most common materials used for sinks is stainless steel. This is a good quality material that rates well in terms of durability, cost-effectiveness and maintenance. This kind of sink is quite sturdy and good quality stainless steel sinks are generally not as noisy some people would expect. Another material used for kitchen sinks is porcelain on cast iron. This material is unaffected by heat or cold but it can be damaged by forceful blows.

Enamel on cast iron or on steel is another alternative. They are resistant to heat and cold and they are easy to clean but like porcelain, heavy blows can damage the sink. If the enamel is damaged, the underlying metal is prone to rusting. There are also kitchen sinks made of solid materials like granite. These are matched with countertop materials to create a chic, modern look. Scratches on these materials can be removed through sanding. The downside of this material, however, is the fact that some of them can crack under heavy force.

Another thing to consider when choosing sinks is the tapping arrangement. If you intend on having many sink accessories, such as a sprayer and a soap dispenser, you have to consider how they will be arranged around the sink bowl. Function is more important than form. What may look good is not necessarily what is best for you and your kitchen, so choose wisely.

Renewable Energy Sources Primer

There are numerous renewable sources of energy available to power home and industry. These include, wind power, hydro-electric, biomass, and solar to name a few. Understanding which ones are best suited comes down to a question of geography and economics. Home and business owners are often presented with colorful options on the wide variety of alternative energy sources available, but can find themselves faced with a large up-front cost and only a vague idea of what the savings and payback period would be. Now, I want to point out that the savings and payback period should not be the only criteria for making a decision. I firmly believe that environmental responsibility should be a high priority, but am also sympathetic with anyone who refuses to pay tens of thousands of dollars to install a system in order to completely live off the grid. There should be serious effort on the part of industry and government to invest in the advancement of the technology, and to drive down the cost, in order to make it easier for homeowners and businesses to make a shift in their energy use.

Shifting global energy use towards cleaner sources is very possible, but it will require a utilization of all the renewable sources available worldwide. This will mean that the areas of the world that are rich in geothermal energy, would contribute to the energy "pot" along with those areas that are rich in say, wind energy or solar energy. There are few places in the world that will have all their energy needs satisfied by a single local and renewable source. This will mean that "sharing" of renewable energy must occur across all borders. It will take a keen understanding of what best applies to different areas and then proceeding forward. For the most part this must happen on the industry scale, where the economics of scale will make it most feasible. Individual home and business owners can certainly do their part as well, either in using less energy and/or reducing dependence on the grid by installing some solar panels, or maybe a wind turbine, which they can afford. Certainly those people with larger properties, such as farmers, can make the most of this. But most don't have this opportunity. So for the most part, renewable energy must come from large scale applications designed to power hundreds, if not thousands of homes, per installation.

Let's look at the key areas of renewable energy potential.

Solar Energy

Photovoltaics

Photovoltaics (solar panels) can generate electricity year round but their output can vary depending on if it is sunny or cloudy. Their output efficiency is 10-15%, meaning that 10-15% of the solar energy that reaches the solar panel is converted into electricity, which is somewhat low. Furthermore, their cost is high, around $10/Watt if you're looking at a home installation. The cost per Watt tends to be lower for large utility-scale installations.

Solar panels utilize the "photoelectric effect" to produce electricity. The sun's photons excites the electrons in the photosensitive panel material to produce electricity. The technological hurdle in constructing solar panels is that the photosensitive material made out of high-purity silicon, has to be "grown", which is a slow process. Because of this the economics of scale don't benefit large-scale production of solar panels as much as say, wind turbines which can be produced at a faster rate. Nonetheless, in certain applications solar panels are valuable since they are a consistent source of power as long as there is regular daylight intervals, which is true almost everywhere. If budget is not an issue and you want steady reliable power from one single source that is almost entirely independent of geographic location, then solar panels are for you.

A further advantage of solar panels is that they require little maintenance once they are installed. There are no moving parts. All that is required is to keep the surface clean so that sunlight can get through.

Solar Thermal Energy

This source of power is most suitable in areas where there is little cloud cover year round. It relies on the unimpeded intensity of the sun, just like a magnifying glass will only focus sunlight when there are no clouds blocking the sun. The energy efficiency achieved by solar thermal can be twice that of photovoltaics.

There are two main methods to capture the sun's thermal energy. The first is with flat-plate solar collectors. These are collectors with a clear glass plate on top to help "trap" the sun's heat, much like a "greenhouse" effect. This causes the interior of the collector to heat up. On the interior of the collector there is tubing which is painted black in order to better absorb the sun's heat energy. This, combined with the "greenhouse" effect, will result in the tube temperature reaching 80-90 degrees Celsius.

Inside the tubes there flows a coolant that heats up and then flows out of the collector and exchanges heat with another device, such as a water heater. This helps reduce water heating costs. This heat can also be used for space heating, reducing costs there as well.

Flat-plate solar collectors can also be "evacuated". A vacuum is created between the collector tubes and an outer glass tube. This allows the collector temperature to become even hotter, over 100 degrees Celsius. The reason it gets hotter is because, in the absence of air, there is no heat loss due to convection, which is basically the transfer of heat to the glass tube, with air as the transfer path. With this heat loss medium removed, the collector heats up more.

Solar collectors are among the least expensive of all solar installations, costing only a few thousand dollars for a typical home installation.

The other way to collect the sun's thermal energy is by focusing the sun's energy on to a small area, much like a magnifying glass, resulting in localized very high heat. This high heat can be utilized for electricity generation.

One application for concentrated solar heat is in "power towers". Using many heliostats (mirrors), the sun is focused onto a central tower using tracking mechanisms. The power tower receives this concentrated energy to heat up water and run a steam turbine to generate electricity. Heat from the power tower is initially stored in a salt compound which becomes liquid at high temperature, and its heat is then used to turn water to steam. Because of the ability of salt to act as an efficient thermal storage at high temperatures and low pressure, it can be easily transported through piping and into a storage tank for subsequent use in the steam generator. It can store sufficient heat energy to provide electricity generation well into the night, well after the sun goes down.

The efficiency of a power tower can be around 20%, which means that 20% of the sun's energy falling on the mirrors can be converted into electricity. Efficiency as high as 25% can be achieved with larger installations. Efficiency is somewhat proportional to the size of the installation.

Another means to utilize the sun's thermal energy is with a solar concentrator, such as a SunCatcher system. A Stirling engine is placed near the focal point of a large parabolic dish, around 11 m in diameter. The dish is pointed directly at the sun by using a tracking mechanism. This allows the sun's energy to be focused onto a receiver placed at the focal point. This receiver channels the heat energy into the Stirling engine which then generates electricity.

The Stirling engine is unique among engines in that all it needs to run is a hot and cold source. In this case the hot source is the sun's heat and the cold source is the ambient air. The concentrated heat energy of the sun hitting the receiver can be as much as 800 degrees Celsius! The higher the temperature, the more efficient a Stirling engine will be, which is why a parabolic dish is much more effective than a solar collector as a source of heat. It generates more power per unit area of sun exposure. In the SunCatcher, the efficiency is around 30%, which means that 30% of the energy that reaches the parabolic dish is converted into electricity. This is the highest efficiency of any device that converts solar energy to electricity. It is comparable to coal generating stations which can operate with an efficiency of 35-40%. Each SunCatcher can generate an average of 25 kW of power. That is enough power for a dozen homes.

The SunCatcher is ideal for scalability in that it is modular, meaning that to get more power you simply add more units. This type of scalability is not as easy to implement for a power tower.

Areas such as the southwestern United States are ideal for solar thermal energy. Any areas that have ample sun and little cloud cover year round, are suitable. The outdoor temperature does not have to be hot year round. As long as the sun is shining the receiver can reach a high temperature. In fact, the efficiency record for a SunCatcher was set on a cold and sunny winter day. This is because the cold "source" temperature, which is the ambient air, is colder than in summer months. And since the efficiency of a Stirling engine increases with increasing temperature difference between the hot and cold source, it resulted in a higher than normal power output.

The disadvantage of a SunCatcher power plant is that it can only output power during the day. There is no overnight storage capacity as is the case with a power tower. However, it is still valuable as it can help reduce grid load by offsetting some of the peak power use which is generally during the day.

Currently, these SunCatcher units are very expensive, around $250,000 per unit. However, this is the cost of making prototypes. Economics of scale can greatly reduce the cost, since these are essentially mechanical devices which can be manufactured at high volume, the same way as automobiles. And indeed, they are not as technologically complex as many of the cars produced today.

Wind Turbines

Wind turbines have little environmental impact and in high volume can greatly contribute to grid quality electricity. For large installations (on the order of MW), the rated power output is 1 Watt per 1-3 dollars of installation cost. Compare this to large installations of photovoltaics that have a rated power output of 1 Watt per 4-7 dollars of installation cost. Wind is (currently) a better return.

Wind turbines are one of the largest sources of renewable energy production in the world. In Germany they supply nearly ten times as much energy as photovoltaics. The same can be said of the European union, which leads the way in renewable energy development.

As said before, it's easier to produce wind turbines in large volume than photovoltaics, since they are basically mechanical devices. This no doubt contributes to their much larger numbers.

Wind turbines work best on a large scale in large open areas, where one can install towers tall enough to capture the full brunt of the wind energy available. Coastal areas and areas near large bodies of water are often best suited for wind power.

Wind turbines can be very large, up to 200 meters tall, with 125 meter blade diameter, providing up to 6 MW capacity. One such turbine can power thousands of homes.

To have the best chance of producing steady output power, it is necessary to install wind turbines in numerous locations, spread out across large regions. This way, even if one area has insufficient wind speed, statistically speaking there is enough wind blowing in different areas such that the wind turbines will produce steady output on average. Wind speed varies much more with respect to local regions than does other sources of energy such as solar, so multiple installations covering a large area is essential.

Geothermal Power

This is heat energy that is captured from underground, which is escaping from the earth's core and venting close enough to the earth's surface to be accessible. Certain areas of the world are rich in geothermal energy, such as Iceland. This energy can be used to heat water and create steam to power turbines that generate electricity. It can also be utilized to heat homes.

The technology is progressing so that areas that were previously considered "too deep" to access geothermal energy can now be drilled and tapped. This will contribute to the number of areas that can be harvested for geothermal power.

Wave and Tidal Power

Wave power is generated by using the "up and down" motion of waves to drive a generator using an actuator such as a hydraulic ram.

Tidal power is generated by placing turbines underwater that rotate due to the bulk motion of the water. This is similar to how wind turbines rotate in the presence of wind.

Biomass

This entails the burning of plant matter for energy. It is carbon-neutral because during the life of a plant, it captures carbon dioxide from the air, using photosynthesis. This carbon is stored in the plant tissue. When the plant is burned it releases its stored energy as heat and the carbon dioxide returns to the atmosphere. So there is no net gain or loss of atmospheric carbon dioxide. Therefore it is carbon-neutral. Sources of biomass can be wood or plant husks. Ethanol derived from sugarcane is another example.

Hydro Electric Power

Many are familiar with this mode of power generation. It is the kind of power that uses the gravitational potential of falling water to rotate large turbines. Niagara Falls is an example, along with the Three Gorges Dam in China, which will produce 22 GW of power when completed. That is enough power to supply almost the entire province of Ontario.

Hydro-power is an excellent source of power when used from natural sources. It can become an environmental problem when large stretches of land are deliberately flooded to achieve it. Notwithstanding, it remains one of the largest sources of renewable energy.

Looking at all these options, it becomes clear that the solution is not a single one, but all of them put together. Different areas of the planet would lend themselves to different renewables. Some areas would be best suited to solar energy. Others may be better suited to wind power. While others may be best suited for geothermal or even tidal power. Combinations are certainly possible if the natural conditions favor it.

It's also clear that mechanical means of extracting energy from nature will form the bulk of clean, non-polluting, energy sources. It is a fact that the motion of wind and water lends itself more easily to power generation in more areas of the world than does solar. And it's fairly easy to scale up these sources. You just "add" more units.

The job of government and industry is to push for large scale installations where they are feasible, as they will supply the bulk of the electricity needed by society. Economics is not the only hurdle here. There has to be a willingness to invest in something which cannot have a price tag on it. Maintaining a habitable planet should be a priority no matter what.

The role of the home and business owner is to participate in the effort to use less energy, and conserve more. This could be by driving less, using public transit more, installing more energy efficient appliances even if it costs more, and being more cognizant of where energy use in general can be reduced. Doing this and making this part of a way of life need not be perceived as a sacrifice, but a responsible way of living harmoniously with our surroundings.

Ranch House - Renovation Best

What is the common dream which motivates people to boost income? Undoubtedly, to live a comfortable life in a lavish house with an aura of opulence all around. So they aim at furnishing their nest in a manner that would set it apart from the rests. A ranch house could be the ultimate image make-over of a house. A ranch house is simplicity at its best. It is a one-storey building in a picturesque backdrop. This particular type of house serves two purposes at the same time: it adds up to the beauty of the house and looks after the utility aspect as well. But before setting up a house, one needs to know why he or she needs a ranch house and if it is necessary or not.

Before going deep into the details, the basic idea of ranch house and its renovation should be apparent enough. The mandatory components of a ranch house are several bedrooms, cooking area, washroom, a drawing area and rooms for guests. Cellar and conjoined parking area with an entrance into kitchen are other basic features of this kind. So, if you want to renovate a ranch house, fence the terrace, add a gallery or erect a partition to divide a big room and you are sorted.

Before venturing you must be focused about your demand from this remodeling. Its sole intention should not be only to beautify the house but also to utilize the area properly and enhancing it. A little planning beforehand helps a lot. You can start with tracking down the drawbacks of the prevailing house and correct it as soon as possible. A wooden deck or something unique can be added to complement the rest of the decoration. Even a new and extra structure can be added to the main one. But it must be in accordance with the design of the rest of the house and serve the purpose of spending free time.

Even if you are happy with the look, space enhancement could be a necessity. In that case an additional library or bedroom can be spaced out. It will change the exterior look too. It will be good change in favor of the restoration. If the planning does not go down well with the present interior due space scarcity, the cellar can be divided to increase the area.

The general use of cellar is that of a storehouse, launderette and hot water reservoir. If you surrounded it with walls with enough room spared, the extra space can be transformed into children's recreation room or for relaxation of your entire family. So, the ranch house increases the value and utility of the house.

DIY Solar Power System - Useful Tips When Building a Power System Using Solar Panels

With a DIY solar power system in your home, you can convert sunlight into electrical energy without spending much. The amount of electricity which you can produce through this will depend on the number and size of solar panels you have installed and the amount of direct sunlight these panels are able to capture.

Since sunlight is a renewable energy source, this solution will not be detrimental to the environment. In fact, if more people will opt to use this form of power, the less pollution there might likely be. Aside from being a practical solution to the problem of high electric bills, this can also be used as an opportunity to earn money. If the solar panels that you installed are able to produce electricity that is more than enough for your consumption, you can choose to sell these excess power to electric providers.

Nevertheless, installing a high quality solar power system in your home does not always come cheap. You would have to spend not only your money but also your time and effort to make sure that the system will be sufficient for your needs. There are certain factors to be considered before deciding to have such an energy producing unit in your home.

First, you have to make sure that you will be staying in your house within a duration that will allow you to recoup whatever you spent for the energy system you installed. Otherwise, the money you spent will go to waste as you are not able to fully benefit from it.

Second, you have to make sure that the area of your roof is large enough to support the solar panels that will be installed there. It should be possible for them to be exposed to direct sunlight within a minimum of six hours. Moreover, make sure that there are no trees nearby as these can obstruct the rays of the sun.

Third, if you do not feel confident installing the units on your roof, opt to hire a professional. This way, you will not have to worry about inefficient installation. Consider this when preparing your working budget for solar power system installation.

If you choose to buy ready-to-install energy units, make sure to buy only from reputable sellers or retailers. If you would like a DIY version, buy your spare parts from trusted sellers. Look up the yellow pages or your local newspapers for the names of these possible sellers. Moreover, when choosing where to buy from, select those that offer telephone technical support and warranty. If you prefer a DIY solar power system, better ask assistance from people who are more experienced with such tasks.

What is Cladding - Home Advice

In the building trade (and for your home) the term 'cladding' refers to applying one of many types of materials to the external walls of a house to increase protection from the elements. Cladding protects a home by reducing the infiltration of rain or damage caused by frost for example. As well as increasing the protection of your home, it can also add a stylish and modern touch to homes and commercial buildings.

What types of cladding are there?

Wooden cladding

Popular choices include pine and spruce although larch and cedar are also good choices as they can be used untreated. As wood can be cut and trimmed to any size, you can select from a range of sizes to suit your home. Make sure you speak to the experts about the thickness and size of cladding most suitable for your home. As every tree is different, wooden cladding can create a really unique look to your home. You can purchase it pre-treated or for the individual look you can treat it yourself with a wood-stain to get the finish and colour you require. With wooden cladding it's important to make sure the cut ends of the wood have been treated with preservative to ensure water doesn't seep in and warp the wood.

UPVC cladding

UPVC cladding is generally a cheaper alternative to wood but it can look just as attractive. UPVC is very easy to maintain which means you won't need to worry about the upkeep of your cladding if it's been installed correctly. UPVC cladding doesn't require painting so it's a great solution if you want an attractive look without the hassle. This type of cladding is versatile enough to be used on any style of home to increase the protection of the exterior walls.

Stone cladding

Natural stone cladding is a great look for property of all ages, particularly properties in rural surrounds. If you want the effect of stone cladding but without the expense of covering your whole home then you can add subtle touches such as to your porch, garage or the side of your house which takes the brunt of the weather. Stone cladding is very durable so is a great long term investment. If you have a large budget then you can really make an impact with luxurious stones such as granite or marble. Stone cladding is a popular choice for business properties such as hotels or offices as it looks stunning and can make a building really stand out. It is also a regular feature in lobbies, entrances and receptions and stones such as quartzite have a natural sparkle to them which adds a real touch of luxury.

Don't forget that wood and stone cladding can also be fitted into your home's interior. Marble for example can be a stylish and low maintenance option for bathrooms and as it's durable, it saves on the time and cost of refitting tiles every few years.

Cladding can have considerable benefits including protecting your home and creating an aesthetically pleasing look. It can be difficult to remove though so make sure you consider all the options and speak to the professionals before you have any fitted.

Glass Railing - Where Class Should Be Visible

Add Sparkle To Space Use Glass Railings

Glass railings with some transparency and a lot reflection from glass can create a different kind of atmosphere to a place that has been lit up brightly. If you see a Dubai gold mart for example, you will be able to see lot of glass railing in market. The well-lit mart becomes alive with reflection from gold and the use of glass everywhere, including the railings, accentuates the feeling of fun of shopping.The complete reflection from all surfaces adds to the glitter of gold there. If you use wood or any other railings there, the effect will not be as electric.

Customized Solutions - Glass Railings

Glass railings are never available as ready made material that can be cut and fitted as required. When you wish to use glass railings, the idea is to accentuate the atmosphere of the whole place and hence you may have to consider the all the factors including the lighting. The holistic approach has to be applied to the whole place rather than just fitting the glass railings.

Advantage Glass Railings No Maintenance Absolutely

The main advantage of the glass railings is that it requires no maintenance at all. There is no requirement of polishing or the possibility of mildew formation or and degradation of quality of the installed railings. Apart from the general cleaning, the glass railing continues to look as good as new all the time. Replacements unless the glass breaks are not necessary.

Advantage 2 - Tender Handling By Customers

Because of the perception of glass as breakable material, everyone handles it carefully even when tender handling is not required. Therefore, when children try riding the railings, immediately the parents come in and prevent the children from doing so. This happens, as the glass is feared to be breakable even when it is not and this prevents any undesirable incidents in a shopping complex.

Advantage 3 - Inviting Atmosphere

The glass with its openness results in a place where the shoppers feel invited and indulge in more shopping than may be warranted by their capacity and the shop owner gets the advantage of higher turnover.

Photo Luminescent Egress Systems Are Simple, Smart, Economical and Eco Friendly!

Recent developments in technology and innovation have made it possible to replace yesterday's evacuation / egress lighting systems with energy saving photo luminescent systems. These systems consist of mainly high-tech glow in the dark materials that are used to outline hand railings, door frames, steps, lettering for emergency exits, stairwell exit signs, fire exit signs and more. Building emergency lighting regulations require that all exits in public buildings be clearly identifiable in the case of power outages, or smoky conditions due to fire. With today's technology these requirements can be met without the use of electronically powered signs, or self powered radioactive systems. This in turn creates a huge savings in energy costs and greatly reduces the cost of maintenance and the hazards of handling radioactive material.

Photo luminescent systems are simply the best choice for our planet. They require no electricity or power, which greatly reduces the carbon footprint left behind by the outdated systems of yesterday. Today's systems are Eco Friendly, and they utilize materials that allow the energy from daylight and interior lighting to be absorbed and stored. This stored energy is then released as light, just like those "glow in the dark" stickers or toys that you most likely have played with as a kid. The only difference is that the technology and materials have been greatly enhanced in resent years, providing much more useful light for longer periods of time.

Photo luminescent systems are very versatile. Not only can you see this material being used in signs for lettering, but it has also been cleverly incorporated in to the actual outline of steps and hand railings. Imagine being in a building during a blackout and being able to see the steps, hand railings and doorways outlined in a glow in the dark border. I am sure you can image, it makes for an easy escape and helps you adjust your depth perception while moving about in the dark.

Another great benefit of this technology is that these systems are weather proof. The sustainable design and construction of photo luminescent signs will provide many years of non maintenance use both indoors and out. It is estimated that these space age materials could last up to 35 years!
