Author : Aydan CorkernAntennas are no longer remnants of our grandparents’ childhood because they are back in the mix and are stronger than ever Their appearance and performance have been greatly improved upon so that they appeal to those who want something pleasing to the eye and so they can compete with pricey cable and satellite service If you are considering investing an antenna, then there is probably one very important question you have that is more important than any other question or concern you might have about your purchase That question is: what is the best HDTV antenna?

And what is the simple answer to that question? The best antenna is the one that works! There is nothing worse than investing in an antenna that you saw at your local retail store, setting it up at home, and being disappointed that it did not live up to its promises of picking up high-definition channels Many packages will claim that their antenna is the best in the business, but when put to the test, they tend to underdeliver and fall very short on their promise

Perhaps the best way to go about picking the right antenna for your home is by visiting a website that will allow you to input your address and other information about your surrounding area, which will help you determine which antenna will work well Another way to go about it is to read customer reviews When you’re bombarded with promises on the packaging and you can’t really discern which ones are true and which ones are false, the next best thing is to find other people who have used that same antenna There are plenty of product reviews from several sites You might come across a product that generally gets good reviews and might have a few negative reviews This is common, and you will have to wade through the reviews, both positive and negative, to weed out the bad antennas

One other way is to find an online retailer that has actual hands-on knowledge about antennas Or you can find a sales associate with experience with antennas at your local retail store Don’t settle for a product that was recommended by an associate who basically read what was on the box to you when you asked for help without seeking a second opinion or relying on reviews The price of an antenna might not cost very much, but you don’t want to throw away your money either, let alone have to go through the hassle of returning it

Personally, the Channel Master 4228 Antenna works excellent if you’re looking for an outdoor antenna If opting for an indoor one, then the Clearstream 4, which can be used for both indoor and outdoor use, is a good buy How well it works is determined by where you live, so make sure you do the proper research before investing in any antenna

Once you find the right antenna, you will be very happy that you invested a few minutes or hours of your time in searching for the right one Aydan Corkern is a writer, HD enthusiast, and promoter of plasma mounts and

Author : Bercle GeorgeThere has been much debate about what is often called ‘free’ energy-energy that can supposedly, with the right technology, be drawn straight out of the atmosphere, and in very abundant supply The debates are about whether the stuff actually exists or not, what it would actually cost were it to be harnessed, and if it does exist is it truly as abundant and efficient as it’s being made out to be by proponents of research and development into this potential alternative energy source

When one hears the phrase ‘free energy device’, one might be hearing about one of several different concepts This might mean a device for collecting and transmitting energy from some source that orthodox science does not recognize; a device which collects energy at absolutely no cost; or an example of the legendary perpetual motion machine Needless to say, a perpetual motion machine-machine which drives itself, forever, once turned on, therefore needing no energy input ever again and never running out of energy-is impossible

However, it is not so simple to say that a new technology for harnessing the energy ‘floating’ in the atmosphere is impossible New technologies replace old ones all the time with abilities that had just been ‘impossible’ Harnessing the power of the atom for providing huge amounts of energy was ‘impossible’ until the 1940s Flying human beings were an ‘impossible’ thing until the turn of the 20th century and the Wright Brothers’ flight

The biggest claim of the proponents of ‘free’ energy is that enormous amounts of energy can be drawn from the Zero Point Field This is a quantum mechanical state of matter for a defined system which is attained when the system is at the lowest possible energy state that it can be in This is called the ‘ground state’ of the system Zero Point Energy (ZPE) is sometimes referred to as ‘residual’ energy and it was first proposed to be usable as an alternative form of energy way back in 1913 by Otto Stern and Albert Einstein

It is also referred to as ‘vacuum energy’ in studies of quantum mechanics, and it is supposed to represent the energy of totally empty space This energy field within the vacuum has been likened to the froth at the base of a waterfall by one of the principal researchers into and proponents of Hal Puthof Puthof also explains, the term ‘zero-point’ simply means that if the universe were cooled down to absolute zero where all thermal agitation effects would be frozen out, this energy would still remain What is not as well known, however, even among practicing physicists, are all the implications that derive from this known aspect o quantum physics

However, there are a group of physicists at several research labs and universities who are examining the details, they ask such questions as whether it might be possible to ‘mine’ this reservoir of energy for use as an alternative energy source, or whether this background energy field might be responsible for inertia and gravity

These questions are of interest because it is known that this energy can be manipulated, and therefore there is the possibility that the control of this energy, and possibly inertia and gravity, might yield to engineering solutions Some progress has been made in a subcategory of this field (cavity quantum electrodynamics) with regard to controlling the emission rates of excited atoms and molecules, of interest in laser research and elsewhere For more on science, technolgy & related topics visit : http://www.science-and–technology.com/

Author : Anna StenningLarge businesses will have heard of a data centre and will most certainly have become very dependent on their services These not only act as a backbone to the back up of all vital confidential information that the company holds, but they are also an excellent place for extra space and storing hard copies of information Electronic information and hard copies are generally kept separate and there are generally little or no clutter around the server machines

In order to keep a data centre up and running smoothly it is important to remember that the buildings are running 24 hours a day and that every inch of the building must be kept protected so as to prevent any serious damage The building itself is purposely built to withstand shock vibrations, protection from large impact from external elements, for instance an earthquake or bomb threat These fall targets to attacks because some of the largest corporate businesses will be in danger of any form of threat and therefore will need a high level of security

The building itself is highly protected and made from strong materials designed to take strong impacts without damaging the machines within Fire prevention is also essential to the protection of a data centre, therefore the materials used in building one will almost certainly have to be fireproof and regular fire safety inspections will need to be conducted There will also need to be a technical engineer nearby at all times to conduct tests and ensure the safe usage of the equipment With this comes the responsibility of dealing with any issues, problems or damages to the machines

The buildings itself is highly secured, with visitors having to go through various levels of security checks before entering into the building They must hold a valid pass and forms of identification as a precautionary measure Any unauthorised individual would always need to be present with an authorised individual and may only be allowed access to specific rooms Security measures will always have CCTV running with each guard monitoring the rooms accordingly so as to observe any suspicious activities

The server machines itself need to be kept in very cool air conditioned rooms, that have a built-in fan to keep the machines itself from overheating Furthermore the server machines are kept in server racks that protect it from external shocks and airborne material e g dust or other foreign particles getting into the system Humidity and condensation is a problem that can occur in the server rooms causing damage to the way the system works In order to regulate the humidity levels of the rooms, ancillary humidification systems are used keep the balance, which also work in conjunction with the air conditioning systems

With any data centre there is always a stable backup system, whereby the entire building will have a power backup system should there be an unexpected power surge As the data centres may hold vital and confidential information, it is always important that the information is backed up, in case of any situations that may increase the risk of losing the data As it happens this system works in businesses as well, as the data centre is seen as a backup system for the company making it all the more important to increase protection of the centres Anna Stenning is an expert on how a data centre is kept secure and why its protection is vital to all large companies.

Author : Bercle GeorgeWe all know that using solar energy is a good thing to do We have heard, and there are quite a number of them, all about the benefits of solar energy and we cannot agree why we cannot turn this alternative form of energy source to a primary one But despite the advantages, solar power has yet to fully make it in the mainstream Let’s go back and discuss a couple of the advantages of solar energy and see why keep going back to fossil fuels for energy resource

In the long run, solar power saves money Initial costs of installation and operations may be more expensive that other energy forms but after settling the expenses, you have an energy resource that is free Nobody charges for using sunlight, right? The return of investment can also be shorter depending on how much energy you use You won’t spend too much on maintenance either plus those photovoltaic cells can last for 15 to 20 years There are no mechanical or moving parts to oil and maintain nor are there parts that need to be replaced yearly

Of course solar power is environmental friendly First its renewable not like fossil fuels which according to studies will be gone in four to five decades The process of converting energy to usable electricity does not involve the release of toxic chemicals which can harm the environment Carbon dioxide, nitrogen oxide, sulphur dioxide, lead, and mercury emissions will be a memory of the past when everyone goes solar Relying on the sun for power also helps reduce global warming

Aside from the toxic wastes and pollutants, using solar power will limit other aspects of the energy industry like hazards of working with and transporting oil or natural gas Also, other health risks are present in the use of other fuels like kerosene and candles which are still popular in third world countries With solar energy, these risks will be minimized if not totally eliminated

The use of solar panels is also good for remote areas where providing basic electricity services is troublesome if not totally impossible at all Solar energy can be transported to far flung villages and once installed they can be left alone for years with little or without maintenance Communities in Asian countries have successfully installed solar panels in their community and have been enjoying the benefits of clean and reliable power for years

For a poor country, producing electricity through solar energy can mean independence from oil producing countries which controls the supply and prices of oil With such independence, new policies on energy can be created which will maximize the benefit for its citizens Countries will also not be wary on natural disasters which hampers delivery of oil With this new found independence, countries can invest its national budget on other programs aside from purchasing oil from foreign sources

There are several disadvantages of using solar power and one of which is the costs But thinking about it in the long run, you will see that the benefits of solar energy outweigh the disadvantages Plus, with the current development in the field of science and technology, solar power is becoming more and more convenient and it would not be surprising to find solar energy as a primary source of power in the next few years For more on science, technology, energy and more visit :

Author : Shaun ParkerWell it would seem this is definitely it! Electronics manufacturers have been embroiled in an all out war over the latest technological debate - plasma versus LCD TV’s Here, in an online exclusive just for your information are the results of the war, the findings of the debate and the conclusion of all the advertising, marketing and campaigning for one to beat the other in a showdown of unprecedented proportions:

They’re pretty much both the same

Of course, I could leave it there but then I wouldn’t have an article, just a paragraph However, there is your answer to the sixty four thousand dollar question, or to be more precise, the 800 pounds question, for that is the average price of both the plasma and LCD TV Buy either and you will get a fantastic quality of picture, you will get clarity of sound matched by both parties and you will get it all at a very competitive price

For those still looking to argue the case, all you have is the fact that LCD TV’s use less energy, thus conforming to the ever interfering European Union directives Of course, this is a temporary issue as plasma’s are in the process of change to allow for this legislation So, before long, we will be back here again

I guess at the end of the day much will depend on your personal preference in purely aesthetic arenas (not that easy to say!) and whether or not you feel a loyalty to a particular company

Of course, you could make your decision based on ethics if you were stuck for a reason to debate your TV choice around the social gathering of the moment You could argue that companies such as Bravia have always maintained their integrity to the environment and never ventured down the money grabbing path of gas guzzling plasma’s out of obligation to the near extinct breeds from the Poles

You could say that Bravia have stuck to their guns throughout the debate preferring to forgo sales when less eco-friendly people defected to the plasma side of the fence and they have quietly sat back secure in the knowledge that their ecological awareness would win through

You could also argue with those on the plasma team that yeah, the TV’s are huge, yeah they’re lovely and clear and yeah, they’re cheap but at what price?
Pushing our gazillions of atmosphere destroying ’stuff’ and hogging all the electricity is not green, it’s not ethical and it’s not right But it does make them a lot of money So we get to see our favourite soaps in super size - what are we all? American? Everything has to be big at the expense of right?

No! Now is the time to stand up and be counted Shun the use of massive Panasonic ozone destroying plasma and opt for a serene and pleasant and very, very green Bravia LCD TV This is not a sales pitch - these two companies are purely examples of the directions we should be looking depending on what we want from our at home entertainment LG, Hitachi and Bang and Olufsen also make plasma and LCD TV’s so take your liberty and shop to your hearts content, making the right choice for you, your family and the children of the future Shaun Parker is technology expert with many years of experience in the TV industry.

Author : Shaun ParkerWell, the recession is biting Jobs have gone, homes have been lost and people are drawing in the purse strings, especially when it comes to luxuries such as holidays and entertainment More is being made of in-home entertainment and social gatherings in friend’s houses rather than paying out for clubs, bars and restaurants

Basically, when it comes to entertainment, you have two choices: stay in or go out So, let’s weigh up these two options and see which is more economical
The usual Friday or Saturday night entertainment would involve a night on the town For us girls, this means at the very least some new bling but more often than not, a new top, dress, bag, shoes, make up or one or all of the above These items don’t come cheap but are essential for making sure you feel as good as you need to

With the outfit sorted we just need four or five hours to put the whole ensemble together We make our way into town for a couple of drinks and then move onto a restaurant to line our stomachs for the night ahead You can allow around 40 pound per head up to this point After this, we have club entry fees as well as several more drinks at extortionate rates and before you know it, you’ve blown over 100 pound on a night out, not counting the prior arrangements

Alternatively, you could invite your mates round This takes virtually no preparation for Shove stray socks under the sofa, wipe dust off surfaces with a sleeve and you’re pretty much ready to go Of course, you will be expected to lay on a few nibbles but it’s also good etiquette for guests to bring a little offering of munchies and/or drinks, therefore sharing the expense

So what can you do once your guests have arrived? Well, technology is the way to go at the moment Yes, this article does centre around the fact that we need cheaper entertainment but it’s highly unlikely that people will ever reach a stage where they are willing to forgo their TV’s or computer games so that is the basis for in home entertainment, alone or with friends

A Bravia LCD TV that is set on a wall will have minimal impact in a room In fact, they can even be set up to blend with a wall of pictures by looking like they are a picture frame and being able to transmit chosen pictures when not turned to the TV setting These take up no floor space whatsoever leaving you more room for furniture and more space for your guests

So, now your choice is computer games on your flash LCD TV or DVD’s Well, either option is viable depending on the mood of the evening Generally, a few of the boys getting together would like to play shoot ‘em up games and display their skills and compete with each other On the other hand, get a bunch of girls together, a bottle of wine or four, a few choccies and a couple of weepy DVD’s and your entertainment is complete

So, all is not lost We may not have the money to go out, living it up on the town every night but for a fraction of what that would cost we can have a much more sociable time in our own homes with very little effort Shaun Parker is a TV expert with many years of experience in the entertainment industry.
