When these gases are released in the atmosphere, it absorbs the sun’s energy, emits it to all directions, back to the sun and to the Earth’s surface, keeping Earth warm and suitable for life. When concentration of greenhouse gases increase due to man-made emissions, this in turn causes the Earth’s surface temperature to increase known as global warming. Global warming causes problems not only in the environment but in all aspects as well.

Furthermore, it is known that when carbon dioxide is separated, it is easily absorbed by plants, trees and water bodies and contributes to the rapid growth of the plant kingdom by 50%. Scientists discovered that this is a possible way to decrease excessive greenhouse effect. So in 1994, the UN Framework Convention on Climate Change (UNFCCC) was adopted as a solution to global warming. On the 3rd Conference of the Parties to the UNFCCC, the Kyoto Protocol was adopted, it was known as an international treaty aimed at stabilizing greenhouse gas concentrations. A total of 169 countries ratified the agreement, and the protocol included Emission Trading, Joint Implementation and Clean Development Mechanism (CDM).

This gave birth to Emission Trading, which permits involved parties to trade emission credits and carbon trading by reducing dangerous emission in exchange for money. These have become an opportunity for developing countries. The carbon procurement vehicle also known as carbon fund, became a form of investment strategy that receives money from investors and the money is used to buy carbon credits or to invest in to greenhouse gas reduction projects such as Kyoto Protocol’s CDM and Joint Implementation (JI).

Due to these events, carbon funds have become active participants in the carbon market and in the world.

1. Initial cost will pay for itself:

The cost of enough solar panels to power a home, coupled with installation costs, will be high. Don’t let this put you off, as the system will pay for itself many times over in it’s lifetime in free energy. You can also reduce this cost by doing some or all of the work yourself. Work from doing your own installation, right down to fabricating our own solar panels. The more you do the cheaper it will be, and the faster it will pay for itself.

2. It is free energy:

After the cost has been payed back all the energy your solar plant makes for you is effectively free.

3. It can work even when there is no sun:

It is a common misconception that there has to be bright direct sunlight to generate power. This is not true, a panel will create energy even on a cloudy day. If you live in an area that has lower sunlight levels you will just need more panels. You can even use the energy at night, as during the day you will store surplus energy in a storage battery bank.

4. You may get help with the cost:

Many governments are actively encouraging home owners to use solar energy. Depending on where you live there may be help available to cover part of the costs of your solar power plant. This help is in the form of direct grants or sometimes tax rebates. Check locally for schemes and their terms before you proceed.

5. You reduce your emissions to zero:

The use of solar panel produced energy creates zero carbon emissions. So you can be happy with the knowledge you are doing your bit to save the planet.

I hope I have convinced you that solar energy is a viable way to power your home. With the ever rising costs of traditionally generated energy, and the undeniable fact that we will have to come up with renewable energy sources. There has never been a better time to think about a home solar energy project.

Unfortunately solar panels can be expensive, and if you want to be totally self sufficient you are going to need a lot of them. Luckily you can build solar panels for a lot less than commercially finished ones cost.. Listed here are my best three ideas to help you to succeed in making your solar power dream a reality.

1. The Solar Panel. – As previously mentioned commercially built panels cost a fortune. To make your own you simply need to buy photo voltaic cells. This type of cell reacts to sunlight by producing an electrical current. You simply need to connect these cells together in series, and lay this matrix into a wooden frame with a glass cover. The cells are available on-line, and the timber and glass for the frame you can get from a hardware store. Don’t worry basic wiring instructions will be supplied with your cells.

2. The Battery Bank. – The power from your panels should be routed to a bank of deep cycle rechargeable batteries. The good news is you can pick up used ones for free in most cases. These can then be easily reconditioned for use in your storage unit. Using a battery bank will make sure you have a consistent electrical supply even if the sun isn’t shining. This is a vital element of your home power plant.

3. The Power Inverter. – Finally your 12v DC output from your battery bank has to be put through a circuit that will convert it into AC power at a suitable voltage to be used in your home. You don’t have to understand how this power inverter works, it will come as a complete unit, all you do is connect your battery output to its input, and the inverted output to your domestic wiring system.

Following these tips will aid you to successfully build solar panels, and install a home solar power system. Keeping the cost down by making the components yourself, will mean your installation will pay for itself in the shortest possible time. After this point you will enjoy virtually free energy. Using solar power you will save money, and save our planet too.

WIND TURBINE BLADES BEHAVE IN THE SAME WAY

Returning to the wind turbine blade, just as in the situation for the cyclist, we can observe the aerodynamic and force diagrams in two different situations, when the wind turbine is stationary and when it is running at a normal operational speed. We will use as an example the cross section near the blade tip of a Bonus 450 kW Mk III operating in a wind speed ÒvÒ of 10 m/s.

When the rotor is stationary, as shown in drawing (A) below, the wind

has a direction towards the blade, at a right angle to the plane of rotation, which is the area swept by the rotor during the rotation of the blades. The wind speed of 10 m/s will produce a wind pressure of 80 N/m2 of blade surface, just like the effect on our cyclist. The wind pressure is roughly in the same direction as the wind and is also roughly perpendicular to the flat side of the blade profile.

The part of the wind pressure blowing in the direction of the rotor shaft attempts to bend the blades and tower, while the smaller part of the wind pressure blowing in the direction of the rotation of the blades produces a torque that attempts to start the wind turbine.

Once the turbine is in operation and the rotor is turning, as is shown in the center diagram (B), the blade encounters a head wind from its own forward movement in exactly the same way as the cyclist does. The strength of head wind ÒuÓ at any specific place on the blade depends partly on just how fast the wind turbine blade is rotating, and partly how far out on the blade one is from the shaft.

In our example, at the normal operating speed of 30 rpm, the head wind ÒuÓ near the tip of the 450 kW wind turbine is about 50 m/s.

The ÒmeteorologicalÓ wind ÒvÓ of 10 m/s will thus give a resulting wind over the profile of about 51 m/s.

This resulting wind will have an effect on the blade surface with a force of 1500 N/m2. The force ÒFÓ will not be in the direction of the resulting wind, but almost at a right angle to the resulting wind.

In the drawing on the right (C) the force of the wind pressure ÒFÓ is again split up into a component in the direction of rotation and another component at a right angle to this direction. The force ÒFaÓ at a right angle to the plane of rotation attempts to bend the blade back against the tower, while the force ÒFdÓ points in the direction of rotation and provides the driving torque.

We may notice two very important differences between the forces on the blade in these two different situations and forces on the cyclist in the two corresponding situations. One difference is that the forces on the blade become very large during rotation.

If vector arrows illustrating the forces in the diagrams were drawn in a scale that was indicative of the sizes of the different forces, then these vector arrows of a wind turbine in operation would have been 20 times the size of the vector arrows of the same wind turbine at rest.

This large difference is due to the resulting wind speed of 51 m/s striking a blade during operation, many times the wind speed of 10 m/s when the wind turbine is at rest. Just like the cyclist, the blade encounters head wind resulting from its own movement,however head wind is of far greater importance on a wind turbine blade than for a cyclist in motion.

The other important difference between a wind turbine blade and a cyclist is that the force on the blade is almost at a right angle to the resulting wind striking the profile. This force is known as the lift and also produces a small resistance or drag.

The direction of this lift force is of great importance. A cyclist only feels the wind resistance as a burden, requiring him to push down extra hard on the pedals. However with a wind turbine blade this extra wind resistance will act as a kind of power booster, at least in the normal blade rotational speed range.

The reason for this difference is due to the blades streamlined profile, which behaves aerodynamically completely differently as compared to the irregular shaped profile of a man on a bicycle. The wind turbine blade experiences

Experiences both lift and drag, while a cyclist only experiences drag.

LIFT

Lift is primary due to the physical phenomena known as BernoulliÕs Law. This physical law states that when the speed of an air flow over a surface is increased the pressure will then drop. This law is counter to what most people experience from walking or cycling in a head wind, where normally one feels that the pressure increases when the wind also increases. This is also true when one sees an air flow blowing directly against a surface, but it is not the case when air is flowing over a surface.

One can easily convince oneself that this is so by making a small experiment. Take two small pieces of paper and bend them slightly in the middle. Then hold them as shown in the diagram and blow in between them. The speed of the air is higher in between these two pieces of paper than outside (where of course the air speed is about zero), so therefore the pressure inside is lower and according to BernoulliÕs Law the papers will be sucked in towards each other. One would expect that they would be blown away from each other, but in reality the opposite occurs.

This is an interesting little experiment, that clearly demonstrates a physical phenomenon that has a completely different result than what one would expect. Just try for yourself and see.

The aerodynamic profile is formed with a rear side, that is much more curved than the front side facing the wind. Two portions of air molecules side by side in the air flow moving towards the profile at point A will separate and pass around the profile and will once again be side by side at point B after passing the profileÕs trailing edge. As the rear side is more curved than the front side on a wind turbine blade, this means that the air flowing over the rear side has to travel a longer distance from point A to B than the air flowing over the front side.

Therefore this air flow over the rear side must have a higher velocity if these two different portions of air shall be reunited at point B. Greater velocity produces a pressure drop on the rear side of the blade, and it is this pressure drop that produces the lift. The highest speed is obtained at the rounded front edge of the blade.

The blade is almost sucked forward by the pressure drop resulting from this greater front edge speed. There is also a contribution resultingfrom a small over-pressure on the front side of the blade.

Compared to an idling blade the aerodynamic forces on the blade under operational conditions are very large. Most wind turbine owners have surely noticed these forces during a start-up in good wind conditions. The wind turbine will start to rotate very slowly at first, but as it gathers speed it begins to accelerate faster and faster. The change from slow to fast acceleration is a sign that the bladeÕs aerodynamic shape comes into play, and that the lift greatly increases when the blade meets the head wind of its own movement.

The fast acceleration, near the wind turbineÕs operational rotational speed places great demands on the electrical cut-in system that must Òcapture and engage Ò the wind turbine without releasing excessive peak electrical loads to the grid.

Has your hardwood deck lost its beautiful sheen that it once had right after installation? Are you looking at it, after years of neglect, thinking it can’t possibly look good again? Is your deck stained and discolored or mildewed? Relax, you can soon be out on your beautiful deck again.

 There are new products on the market today that will help to not only clean your hardwood deck, but give it a color that makes it look new again. There is no predetermined amount of time you have to wait before cleaning your deck. Everyone’s deck is different. Sun, rain, snow, sleet, ice, and humidity will all affect your deck. When the time comes to clean your deck, do the research to find the products that are formulated specifically for your type of deck.

There are cleaners and brighteners. Cleaners are used, just like their name implies, to clean your deck surface. Brighteners on the other hand tend to confuse people a bit more about what its actual purpose is. The brightener will help you to eliminate darker stains and tends to lighten your deck boards, making them look “brighter”. Usually, a good strong cleaner is all you really need though.

 First and foremost, read and make sure that you understand all instructions before beginning your cleaning process and follow all safety guides. This can’t be stressed enough.

 Start by doing a thorough sweep of your deck. This includes removing dirt, leaves, needles, and anything else found on your deck. If you are using a cleaner concentrate, which many are, you are ready to dissolve the cleaner in a bucket or pail of warm water at the recommended strength. The warm water helps to activate the chemicals in the cleaner. Let the cleaner and warm water sit for a few minutes to allow the activation process to begin.

 While the cleaning mixture is sitting, you need to thoroughly wet your deck using a garden hose. Once the deck is adequately saturated, it’s now time to apply the cleaner. To properly apply the cleaner, a mop, pump sprayer, or pressure washer can be used. Please note that if using a pressure washer, you need to be very careful as not to harm the wood with the powerful jet spray. If you aren’t confident with a pressure washer, I would recommend using the mop or pump sprayer because if sprayed too harshly, it can actually damage your deck boards by causing grain tear out which leaves a “fuzzy layer” after it dries.

 Whichever method you choose to apply it with, let it sit for at least ten minutes, making sure not to let it dry. If it starts to dry before the ten minutes have passed, just mop a little more on, it’s that simple. After the ten minutes have passed, it’s time to add a little elbow grease. Using some sort of scrub brush, scrub all of the loosed dirt and debris from the wood. The amount of elbow grease needed will be determined by the state of your deck.

 Once you have scrubbed your deck until you feel that you have removed as much grime as possible, rinse everything off with a garden hose. That’s it. Once completely dried, your deck will be ready to stain or oil.

Floating wooden floors

A floating floor is where the boards are lightly glued together with PVA wood glue along the tongue joint and laid onto a foam matting or underlay over the existing floor. They are called ‘floating’ floors because of their tendency to move if there are any peaks or hollows in the floor underneath, the sub-floor. There is no physical adhesion between the new wood floor and the old floor and, as a result, some floating floors may flex, squeak or sound ‘hollow’ when walked on, especially if the sub-floor has not been prepared correctly. This is a cost effective way of laying a wooden floor but the end result is often disappointing due to the movement. You can only float engineered wood flooring as solid boards have a tendency to twist if laid in this way.

Nailed wooden floors

Traditionally, secret nailing through the tongue of the board was the preferred fixing method when laying a wooden floor. The installer uses either a manual or a pneumatic nail gun and fires special wood fixing nails or cleats through the tongue, which is then hidden when the corresponding groove abuts the board. Solid or engineered wood flooring boards can be laid to timber battens laid on the floor or direct to timber floor joists. In some cases the timber joists can be stuffed with insulation and overlaid with membrane to reduce cold spots in older houses. Alternatively, nailed floors can be used on concrete sub-floors by fitting a 16-18mm layer of plywood or OSB to the concrete first. The resulting nailed floor will feel solid and substantial during use. That said, nailed installation is a specialist skill and should is not recommended for the amateur DIY’er!

Glued down wooden floors

Glued down installation is probably the most common wood floor fixing method used these days. Here the new floor is laid using a full coverage flexible wood adhesive to the sub-floor; which could either be a concrete screed, existing floor boards or a plywood/OSB board. Modern silane adhesives are applied to the sub-floor using a trowel, a little like tile cement, and the boards are placed directly on top. These new wood adhesives are very strong, odour free, water based and have a good ‘open’ time allowing ample time to complete large areas of flooring using an open tub. A glued down wood floor will feel as solid underfoot as a nailed floor and, because the glue is flexible, natural seasonal expansion and contraction can occur without stressing the floor.

1. Stools – This item is essential to make your tiki bar that much more aesthetically pleasing as well as comfortable.  The first reason to include stools is obvious… For comfort!  By adding stools, enjoying a fresh cold drink will be much more enjoyable if you and your guests can sit down and take a load off.  Another reason for adding stools, is that they can add a classy and authentic feel.  Adding stools will remind you and your guests that your tiki bar is as authentic as the ones found on any tropical island or beach.

2. TV – This item has also become a staple for entertainment this day in age.  Having a TV as a part of your bar will add yet another piece of entertainment while you are relaxing day or night.  Its recommended to get a flat screen TV so that you can utilize as much room as possible, while still adding a great piece of furniture that will always guarantee to add hours of entertainment. Adding a TV to your tiki bar will transform it into an even greater social hotspot.

3. Lighting – This is great accessory, or piece of furniture if you will, to really add uniqueness and pizzazz to your custom tiki bar.  There are literally thousands of ways to decorate through the use of lighting.  The wonderful part about it, is that there is no right or wrong way to decorate with lighting.  You can use track lighting, string lighting, colored lighting or mirrored lighting, the list goes on and on.  This is an opportunity to literally let your creativity shine! 

4. Art – This category of furniture is another great way to let your personal flair and creativity shine.  Here again there is no right or wrong way to decorate.  The most popular choices are anything and everything that you could relate to an island setting.  This could include seashells, palm leaves and bamboo rods.  Many people often incorporate more of a contemporary touch with strategically placed mirrors and some personal décor such as picture frames or funky glasses for drinks.  This is yet just another way to really let your creativity shine. 

5. Cooler– Another piece of furniture that I will be going over today is the cooler.  This is one of the most important pieces of furniture you will need to include in your tiki bar.  To get maximum enjoyment you will need to ensure cool and chilled drinks, especially on those warm summer days.  There are several options to get these cold drinks.  The first is to have an electric fridge that can produce ice and keep other items readily cold.  This option is definitely a good one and can provide convenience when providing cool drinks.  The other option is to use a cooler of any size filled with ice.  This can also be a great choice as it will essentially get the job done just like an electric cooler.  Either option is fine as long as you and your guests can have a cold refreshing beverage in the shade of your tiki bar on those warm summer days.

Incandescent Bulbs are not really used as a main source of plant growth for a greenhouse. They often burn too hot for plant use. If this is your only option I would suggest placing the light not closer than 2 feet away from your plants. These lights are used mainly for providing general lighting.

Metal Halide, High Intensity Discharge or HID grow bulbs provide the most natural light for any greenhouse. Without talking about the science behind these lights, all you need to know about Metal Halide lights is that they produce a high intensity light at the right color spectrum to grow plants, last much longer than your incandescent lights and mimics the outdoor light all with the same electrical output as incandescent lights.

Fluorescent Bulbs are fast becoming the popular choice for indoor gardeners. These lights can promote plant growth while remaining fairly cool and because they don’t produce an intense heat, gardeners use these lights at close range to help start up seedlings. Nowadays there are fluorescent lights that produce a higher intensity light, which gives you more options to choose from. But multiple choices can be a burden. Combination, conversion, 2000k or 5000k, dual spectrum, etc. There is so much new jargon with greenhouse lighting nowadays that it’s intimidating. That’s why it’s best to keep it simple.

High Pressure Sodium HID bulbs have the longest bulb life. Because these lights don’t produce a light spectrum as good as the previous mentioned lights, these lights are not necessary for the scope of this article.

LED lights are the new kids on the block, and though they’re making televisions better nowadays, it can’t be said for the use of grow lights. Maybe in the near future, advances in technology will turn things around, but as pricey as these lights are, it’s better to wait it out.

So what do I suggest you start off with?

For starters, you should invest in Metal Halide HID bulbs. Because of their wide range of use and durability, Metal halides are the ideal lights from starting up seedlings to growing plants on a larger scale.

Novices still need to take care when handling these lights.

Though different plants require different amounts of light, the output of HID bulbs are intense, and you should not have these on in a greenhouse for the whole day. Contrary to popular beliefs, if you want to promote a healthier plant growth, give them a break from light.

So how can you solve these kitchen organizing problems? One solution for the paper issues is to make a house rule that all paper must be out of the kitchen every night or every other night (depending on how much you can stand it).

Another thing you can try is setting up a specific area of your kitchen just for paperwork. Give each family member a labeled specific area that is theirs. A mailbox type setup can work well. The trick to this is that when each person’s area or mailbox fills up, then they need to empty it out.

What about those random items that end up in the pantry? How can that kitchen organizing issue be solved? One thing that can help is designating certain areas of your pantry for certain things. In my pantry there is a certain area for appliances, another for bulk food items and another for extra tupperware. If it does not fit into one of the designated areas I have, it does not go in the pantry. There are a few exceptions (things that simply cannot, because of their size, fit anywhere else) but those exceptions are rare.
