Energy-Saving & Environment Friendly Led Light Bulbs

by: Green Sim (reading – 4.2. - 10.2.)

Technological advancement is only possible through constant research and innovations. The latest example of such progress is the LED light bulb. Most research is carried out in order to find a way of improving the performance of an existing facility or to find a new product that will prove to be more economical and more efficient than the existing facility.

Positive Aspects of LED Light Bulbs

LED light bulbs have been developed to take the place of incandescent light bulbs or halogen light bulbs because they save energy, their efficiency is nearly double that of normal halogen bulbs and they do not have any harmful substance such as mercury. Moreover, these bulbs are environment-friendly because they can be recycled and they do not produce any heat. The durability and life expectancy of LED bulbs is in the region of 50,000 hours, which is much higher than that of the earlier bulbs. As such, once you have installed these LED light bulbs, you can forget about any cost of replacing them in the near future.

Energy-Saving Feature

The earlier incandescent or halogen light bulbs used to dissipate a large amount of energy by producing heat. This meant that the electricity bill was unnecessarily high. LED light bulbs have been created after a lot of research to eliminate the energy wasted due to heating, This has resulted in the creation of the latest innovative LED bulbs that do not produce any heat and consequently use much less energy to light up a room.

Whereas the halogen bulbs were using 85% of the electrical energy to produce heat and only the 15% balance was being used to produce light, the LED light bulbs utilize 90% of the electrical energy to produce light. Halogen bulbs were fitted with filaments through which electricity was passed in order to produce light but these filaments heat up and consume nearly 90% of the electricity for heating. In the case of LED bulbs, which use light emitting diodes for producing light, almost the entire electrical energy is converted into light energy without wasting any energy for heating. By using LED bulbs you can save 80% of your previous electricity bill. By using the LED bulbs you can make sure that you are contributing towards lessening global warming because no heating from the bulb is being dissipated into the atmosphere.

Cost Aspect

Although LED bulbs are more expensive than the halogen bulbs, it is almost a one-time expense because these bulbs have a long life, which means they do not need to be changed for a long time. The extra initial cost will easily pay for itself over the years. Moreover, since these bulbs use so little energy, they are environment friendly and do not add to pollution. The LED light bulbs have standard bulb fitting features making them convenient to install and replace anywhere.

GU10 LED Bulbs

GU10 LED bulbs are the most common replacement LED bulbs. Though they are similar to the normal LED bulbs, they have many similar LED lights placed in one fitting. GU10 LED bulbs have a specific type of fastening and in most commonwealth countries such as the UK, New Zealand and Australia; the standard fastening is the bayonet mount. These types of LED light bulbs are mostly used in offices, shops, commercial spaces and in showrooms. They are high in style and efficiency.

Photography In A Pinch

by: Barney Newton (reading – 11.2. - 17.2.)

Good photographers try to be prepared for almost any contingency. Unfortunately, if you tried to carry everything you'd need to meet every contingency in the field, you'd have to pack like a Bedouin trader.

Many times that simply isn't possible and other times it's not desirable. So the seasoned photographer learns to be resourceful. Here are a few miscellaneous tips that can save your back, particularly on short trips near home.

A Monopod

In all but the most extreme lighting situations a monopod can substitute nicely for a tripod and is a lot easier to carry. With practice you'll be able to hold a monopod nearly as stable as a tripod, for a short time anyway.

Another trick for stabilizing a monopod is to wrap the camera strap around your upper arm and push on the monopod while exerting gentle backward pressure on the strap. Similarly, you can place a large clamp on your monopod and use it as a shoulder brace, almost like a gun mount. It might look a little funny but it works surprisingly well.

Working In Sand

For those times you have to drag a tripod to the beach or sandy area, grab three tennis balls on the way out the door. Cut a hole big enough for your tripod leg and fit a tennis ball over each end.

The tennis balls won't sink in the sand, will keep most of the grit out of the end of your tripod leg and you can throw them away when you're finished.

Another great thing about working at the beach is you don't need to carry sand bags, just bring bags. There's usually plenty of sand already on the beach. Those are priceless for weighting reflectors, which tend to act like a sail in ocean breezes.

Bring A Cooler

But leave the ice packs at home. A cooler has several advantages over an equipment case in many situations. They're solid, many have a handle and wheels, and you can sit or stand on them in a pinch. If you lose or break it, you're only out about $40.

You can still carry drinks with the camera gear, but carefully. Get those drink cozies you put in the freezer. Those will keep your drinks cold without bringing down the temp too much in the cooler. The last thing you want to do is bring cold optics or a camera out into warm, muggy atmosphere. Expect instant condensation if you do.

Carry a Bag of Rubber Bands

They're just so handy for so many things and so easy to carry. You can use them for emergency repairs and to keep papers from flying away.

A fat rubber band is handy for dislodging a stuck filter. Wrap the rubber band around the edge of the filter and that should give you enough grip to get it loose.

And, if you're stuck waiting outside a courthouse waiting for a photo op, they're also endlessly entertaining for taunting your fellow photographers.

Incident Light Meter

Many photographers still carry a light meter, even in the days of high end digital SLRs. If you're packing light you can use a styrofoam cup over the end of your lens and use your camera's light meter, hold it in place with one of your rubber bands.

Note that cups do come in different thicknesses, so you may want to calibrate yours using the Sunny 16 rule before you leave.

Record the exposure at the subject, then walk back to shoot the picture.

Growing Tomatoes In Containers Successfully

by: Stella Dawson (reading – 18.2. - 24.2.)

Modern urban living should not deprive you of the joys of home gardening. If you enjoy eating vegetables, you will derive even greater satisfaction in consuming your own homegrown vegetables. Growing tomatoes in containers has always been popular among home gardeners. It gives apartment dwellers a chance to own a garden despite living in small spaces.

Have you ever wondered why do people grow tomatoes in a container even when they have a yard or garden? Well, the answer is simply for better control, flexibility and convenience.

Tomato plants grow well on warm temperature, adequate sunlight and good quality drainage system. Occasional fertilizers add a booster to the plant's nutrients and promote the production of big, juicy tomatoes. Similar to planting in the ground, it is advisable to grow tomato plants indoor carefully and transplant them only when they are strong enough. In transplanting, you should bury as much of the plant stem as possible. This promotes good formation of the roots, which results in an excellent base foundation for your tomato plant.

Growing vegetables in containers allow you to control the state of your growing medium. Once you have discovered your success secrets through your gardening experiments, you can just rinse and repeat it in all your future gardening projects. You can choose total soil-free gardening, organic gardening or a mixture of both. A recommended recipe for good container gardening soil mixture for vegetable growing is 40% compost, 40% peat moss, and 20% perlite.

One of the advantages of having a container garden is that it frees you from weeding and messing with garden dirt. However, container vegetables will require extra care in watering and fertilizing. Tomatoes grown in containers have constrained root coverage and their growth is limited by the amount of water and nutrients in the container. During summer, you may even need to water your container vegetable plants up to twice daily to prevent it from drying up. Give your water thirsty tomato plants ample water and you can expect a delightful harvest.

If you are looking for an easy way out to watering your tomato plants, you can install automated drip irrigators for your containers. The installation is considerably uncomplicated and the price is not costly. The approximate price of an automated drip irrigation system set up ranges between $50 and $100. You could be easing yourself of a lot of hassles if you have a lot of container plants to take care of. It is surely a worthy investment that will pay off well in the long run.

One of the methods frequently used to lessen water evaporation is to apply mulch to your containers. This also aids in keeping weeds down if you are using compost or garden soil. Both pine bark mulch and black plastic mulch work great.

When your tomato plants start to blossom, it is time to increase the fertilizers to twice its usual amount. This helps to encourage fruit production and results in better yields. Always keep your fertilization rate constant.

Having your tomato plant blossoming with delicious-looking tomatoes is a wonderful feeling. However, it is advisable to pick your tomato fruits once they are ripe as this encourages the plant to produce a new fruit.

Growing tomatoes in containers is undeniably a very flexible and productive gardening practice. Be free to exercise your creativity with your container gardens, as tomatoes are generally hardy plants.

Wind Turbine Energy: A New and Green Alternative

When people think about finding green sources of energy, they often turn to solar power. While it is true that solar energy is a clean alternative to using traditional fuels such as gas and electricity, it is not the only green option available. Wind turbine energy is method of generating energy that is not new in theory since there are many who know how to generate electricity using wind. However, wind turbine energy is still a new form of powering an entire home.

Wind Turbines vs Solar Panels

Both solar panels and wind turbines generate power that can be used as an alternative to fossil fuels. Since solar energy and power generated using wind turbines is clean and easily renewable they can both be used by people who are looking for ways to reduce their carbon foot prints by reducing the amount of fumes that are emitted into the atmosphere. It is believed that if the planet turned away from traditional forms of power such as oil and coal the greenhouse affected (the warming of the Earth's climate) could possibly be reduced.

The problem is, people who are interested in clean power do not know whether they should choose solar power or wind turbines. When making your choice think about your climate. If your home does not receive direct exposure to the sun on a regular basis, you might want to consider wind turbines. Remember, the energy stored by solar panels is depleted as electrical appliances are used, so if you are not able to constantly renew your solar energy wind turbines are the best, green, alternative.

Saving Money With Wind Turbines

The cost of installing a home wind turbine might be enough to discourage many homeowners. Since using wind turbines to fuel homes is still new, manufacturers and installation specialists have not had enough time to develop cheaper ways to build and install wind turbines. Having a wind turbine installed for private use can cost from several hundred to several thousand dollars.

The final cost is determined by the amount of energy you and your family will be using since this will influence how much power your wind turbine will need to generate. However, it is important to remember that after the wind turbine is installed you will have a limitless amount of energy at your disposal. Once a wind turbine is working you will no longer have to worry about paying monthly electricity bills which will save you thousands of dollars each year. In fact, your wind turbine should be able to pay for itself after only a year or two.

Going green is a choice that will help you and the environment. By switching to turbine fueled energy you and your family will be able to drastically decrease your monthly electricity costs. Also, switching to wind generated energy will help the environment by reducing the amount of carbon released into the atmosphere. You might also be able to further help the environment by starting a conservation trend in your neighborhood.
