A Google search produces 7g of carbon dioxide

A Google search produces 7g of carbon dioxide

Two search requests on the internet website Google produce as much carbon dioxide as boiling a kettle, according to a Harvard University academic.
US physicist Alex Wissner-Gross has conducted research into the environmental impact of "googling". Environmental physicists are worried about the environmental impact of information technology.

In a statement, Google said it took the issue "seriously", adding "the energy used per Google search is minimal".A recent study estimated the global IT sector generated as much greenhouse gas as the world's airlines put together.

Mr Wissner-Gross's study found a typical Google search on a desktop computer produces about 7g (0.25oz) of carbon dioxide.If you enter another request you obviously end up with double that amount, which is the roughly the equivalent of boiling an electric kettle for a cup of tea.

The Harvard academic argues that these carbon emissions stem from the electricity used by the computer terminal and by the power consumed by the large data centres operated by Google around the world.

Although the American search engine is renowned for returning fast results, Mr Wissner-Gross says it can only do so because it uses several data banks at the same time, producing more carbon dioxide than some of its competitors on the net.

Mr Wissner-Gross says for every second we stay connected to the internet, we produce 0.02g of carbon emissions.

This may not sound like a lot but each day an estimated 200 million internet searches are carried out.

In a statement, Google said that as computers became a bigger part of more people's lives, they consumed an increasing amount of energy - "and Google takes this impact seriously".
It said it had designed and built "the most energy efficient data centres in the world".

Soundproofing a Room in a four step process

Soundproofing a Room in a four step process

I’m sure music has become the life of most of us these days. However for many others it is still a headache no matter if it’s the slow jazz or even the groovy blues. They think that that they already have enough of noise to be faced outside the house. For such people the following procedure would be much helpful in Soundproofing their abodes.

Step 1
You could start by soundproofing your own room. This could be initiated by adding a door sweep to your door. The sweep seal will keep sound from passing through the gap between the bottom edge of the door and the floor. This could be done by simply cutting and pasting a strip of one of your carpets at the bottom edge of your door. But for extreme measures, your sweep seal could be consisting of a metal strip equipped with a noise blocking flapper, which prevents noise but does not cause your door from opening and closing as usual. This will give your hollow-core door sound-blocking qualities which you might attain by spending some extra bucks and replacing your door with a soundproof one.

Step 2
For soundproofing your walls it is not necessary that you go over the hassle of having some specialist soundproof foams to be blown into the spaces between your walls from your attic. Neither do you really need to cover your walls with layers of cork-backed glued to make your place soundproof. Instead you could get started by purchasing attractive designed and coloured, adhesive soundproof mats. The will easily attach to your walls just like ordinary wall papers.

Soundproofing through glue mats if is seen as a hassle you could revert to using sound deadening rugs which are very effective and attractive for the procedure.

Step 3
Ideally walls are not the place for carpeting, so why not add them to the floor where they really belong. Some woolen underlayments would be very helpful in getting that room of your sound proof. Start by getting rugs and carpets in contrast to your wall rugs if any if you live in an apartment especially. Noisy neighbors below could be shut this way. For more effective practice use padding preferably deluxe ones to keep your room cozy and soundproof. Sound waves travel faster and more effectively when induced in an object, therefore carpeting the floor would definitely be helpful as your own echoes or noise would be absorbed.

Step 4
Windows would be another area of importance in combating noise. I can not suggest a better method for soundproofing your room rather than by installing soundproof windows. If you cannot conform with this process all the other efforts that you put in for making your place soundproof might not be as effective. You should under any circumstances try to get soundproof windows installed behind the original ones to protect from external noise through their exceptionally tight seals. Or I’m sure you could at least keep your windows shut !

Plasma or LCD, What would you prefer?

Plasma or LCD, What would you prefer?

There is often a debate whenever you go to buy a TV for your place on whether the performance of Plasma or LCD would be a better choice if you wish for a flat screen. Different people would differ on the opinions based on their past experiences or what they would have heard from others. But in reality there is no definite answer to the issue as both Plasma screens and LCDs are great and both have their own advantages and disadvantages.

In reality, with the advancement in technology the differences between the two have been on a decline. But still you might have to make your choices depending upon your own circumstances such as time, price or even shelf space required. The following are some great points to help you with your purchasing experience.

Plasma Screens – why would you buy them?
According to most analysts Plasma screens offer better picture quality. They may be relatively close to what LCD screens might show but have the best contrast ratios. They have a wide range of qualities that offer you the in depth real picture that you might see on screen. Especially the dark ranges that offer you to see more clearly.

There are other advantages as well such as the cost factor, and the exact size that you might avail as Plasma screens tend to be cheaper than LCDs. Plasma screens have an amazing viewing angle, and the picture appears to be same, whereas LCDs are manufactured using Passive Matrix technology which require you to be at a specific viewing angle for best viewing. This problem is being resolved through active matrix systems but is more costly. Plasma screens are fast adapting to fast moving images while when using LCD TVs you might experience blurry images if they are moving above the speed of 8ms adding to instant response time.

LCD - why would you buy them?
Apparently the greatest advantage of LCDs is seen as preventing from image burns. Image burns happens when there are some images that constantly remain in place, such as the Windows logo or any other desktop background as in computers. This leaves a shadow mark of the image, distorting the quality of image on screen. This would definitely be a much intelligent option if you spend much of your time playing video games on your TV screens for hours.

LCD screens may only appear costly due to their initial costs however not many people know of the fact that they require 30-40% less power. They are light in weight, which tends to make them more convenient even if you want to mount them on walls. Plus another advantage they have over Plasma screens is that people who live on tall buildings would get better picture quality as Plasma TV's use gas, that tend to struggle at heights of about 6500 feet or above. They even have sizes smaller than 32 inches whereas Plasmas do not.

For those who think that Plasma screens have a short life, LCD and plasmas both survive upto a life of 60,000 hours.

Sending Large Files on the Internet

Sending Large Files on the Internet

Each of who takes the advantage of the blessings of the computer and the internet, and does a lot of file management is prone to transferring large data files today or tomorrow. There are few basic ways to do it, however people still don’t know the most perfect and most effective one. For this reason I have taken the opportunity to share my knowledge in helping them getting their tasks done easier.

The most common and well-known, procedure is not always right. I’m sure you know Im talking about e-mail attachments that most of us make along with our e-mails to send such big files to our counterparts. But people usually don’t know think about the problems they are creating for themselves and the receiver by attaching files this way along with the outgoing emails.

Firstly, attaching a file to an e-mail requires you to locate the file and in a way copy it to the e-mail host’s server. Taking minutes before the file is copied depending on the size of files. These data packets then travel through a lot of different networks before it can come in contact into the receiver’s server host. It is then that the receiver too spends huge amounts of time to download the file adding to the longetivity of the procedure. This badly affects the host and your internet when millions of other users are using the same method for transferring data.

The other way of doing it is trying to find a way to reduce the number of times the files may be copied or downloaded. You could do this by simply hosting your file on any of those free file hosts on the internet that you can get by one search on Google. You could then e-mail the link which maybe less than a kilobyte to the destination of that file. Hence, no intermediaries and no unnecessary travel.

This way you could send the file to hundreds of people at the same time, without getting them to wait before their email hosts tend to check for viruses and decrypt data before they get it. You also won't have to worry about your file being lost to a computer crash, a virus or the dreaded "this file is too big and we can't deliver your message" response that a lot of people receive when sending a file that is too big for conventional email.

Another very sophisticated but time saving procedure for those who have better computing skills would be to send Remote Assistance offers to the recipient. This process however should only be applied if the receiving end is seen as credible enough for not opening any other personal files that you may have on your computer. However there is always an option to restrict your shared files if you know which ones would be useful. You could then easily follow the Windows Remote Assistance walkthrough procedure by sharing your IP address to the recipient. He then enters it into Remote assistance program. And just depending on your internet speed you both could be connected in no time.
