The VoIP technology is revolutionizing the world by providing incredible services all over the world. The design of this VoIP is very innovative and convenient; it is the best option for those who want to install a communication system. There are number of companies who are providing VoIP to homes and organizations. A buyer has to do little homework before contacting to VoIP service providers to get the knowledge about this technology.
Installation Of VoIP:
There is no need of other accessories to run a VoIP but an internet connection. With the help of internet this system provides striking feature. In few years voice exchange services has changed remarkably. No separate wiring is required to operate this system; in fact computer wires are enough to install it. Through this amazing service one can get rid from traditional phone cables. By using internet one can make calls through this system in any corner of the world.
Services Provided By VoIP:
Many online companies are providing this advance communication service; which can be use to make calls in quite different ways. By paying monthly payments one can use DID service, provided by this VoIP. DID service is a link between callers and users. Service like access number makes use of extension number by paying online charges. Free calls to customers using some other internet connections; is another amazing service provided by VoIP
By using same transmission one can send voice and data at a time; this adds to the uniqueness of this VoIP. VoIP is affordable too as it saves the cost of additional wires. Within the internet connection coverage, one can make calls from anywhere. Many other outstanding services are provided but VoIP including conference calls, data composition and voice call service
Drawbacks of VoIP:
However VoIP fails to impress industries. Many feels it comfortable to have traditional phone lining but along with high speed internet, DSL in this case. Many think that it is more convenient to have a DSL and traditional phone line system at their homes and offices rather to have an internet connection serving as a mean of communication too. Another problem for this phone system is long distance call, which is difficult to connect, and if they get connect than voice quality is not good. Moreover if internet connection is slow than VoIP fails to provide its promised services. Read More
We are living in a world which is in a havoc situation. There are lot of troubles people are facing, and everyone is encountering pollution. And most of all there is lack of power resources people can’t handle this lacking because this is now became the basic need of modern man to have facilities of power resources.
We have limited the growth of plants and now we are facing the negative consequences their lacking caused us. Now its time pay back all the things we snatched from nature, so we should go green, and to complete this mission we need the support of things like Freeloader Portable Solar Charger. This device will let us to pay back all the liability to our nature slowly.
Here are some of the top technological trends that remained in focus during 2009.
These recently launched mobile phones have the capability to work as a computer as well, allowing users to plug in anywhere. Smartphone sales increased 24% worldwide in 2009, irrespective of the poor economic conditions.
Facebook went through a significant demographic shift, becoming the most favorite social networking website for all age groups.
Blogging gained much popularity in 2009 with the help of Twitter. This helped people to publicize certain issues, such as the protests in Iranian elections, which cause significant turbulence in the politics.
Economizing electricity has always been a worthy goal. It becomes even more in the summer season. People use to reduce the amount of power that desktops and servers eat up. This thing not only reduces the heat but it also reduces the overall cooling load. Power supplies, CPUs, CRT monitors, hard drives and high-quality graphic cards are not major energy pigs, but if all things are running simultaneously they can add up consumption.
The Kill-A-Watt cumulative Kilowatt-hour monitor is a fast and cheap method to calculate how much electric power one PC or monitor is eating up. The Kill-A-Watt sells for approximately 30-USD. It measures volts, amps, watts, Hz and VA (volt-amperes). It is interesting to analyze the differences between a working system (under load), an idle system, and a system that is purportedly “off”. Today, off doesn’t mean off, but rather “on a little bit”.
If I will do this, then this will happen, and if i do this differently then that may happen. Yes, it is what we all keep doing. We all try to define our future steps by planning things and then thinking that this will happen in the end. But what we lack is we see things with our strength and ability. We forget that some people posses ‘can do attitude’ and once they decide to do something, they continue working on it until they get success.
Same is true in technology world as well. Many people from technology world has been predicting, but most of the predictions were cause of a laugh when that time came and prediction turned false. Following is a list of 30 best predictions which never came true. Lets know about them.
1. High speed Rails
Dr Dionysys Larder (1793-1859) predicted that
“Rail travel at high speed is not possible because passengers, unable to breathe, would die of asphyxia”.
Dr Dionysys was a professor of Natural Philosophy and Astronomy at University College London.
2. Making of a Ship against Wind
When Napoleon Bonaparte was told of rober Fulton’s steamboat in 1800, his statement was
“How, sir, would you make a ship sail against the wind and currents by lighting a bonfire under her deck? I pray you, excuse me, I have not the time to listen to such nonsense.”
3. Railroads is a bad system
Martin Van Buren, Governor of New York, in 1830 wrote to the president that
“Dear Mr. President: The canal system of this country is being threatened by a new form of transportation known as ‘railroads’ … As you may well know, Mr. President, ‘railroad’ carriages are pulled at the enormous speed of 15 miles per hour by ‘engines’ which, in addition to endangering life and limb of passengers, roar and snort their way through the countryside, setting fire to crops, scaring the livestock and frightening women and children. The Almighty certainly never intended that people should travel at such breakneck speed”.
4. Telephone has Shortcomings
It was printed in a memo at Western Union in 1878 ( or may be 1876) that
“This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us”.
5. Electric Light will Close as well
Oxford professor Erasmus Wilson predicted that
“When the Paris Exhibition [of 1878] closes, electric light will close with it and no more will be heard of it”.
Today, we can’t expect life without electricity.
6. British Post don’t Need Telephone
It seems British were not believing on fast communications. In 1878, British Post Office gave a statement that
“The Americans have need of the telephone, but we do not. We have plenty of messenger boys”.
How backward thought they were having.
7. X-rays will be nothing but a Hoax
In 1883, the president of Royal Society Mr Lord Kevin stated that
“X-rays will prove to be a hoax”.
8. Alternating Current – A waste of time
Thomas Edison was an American inventor. In 1889 he commented that
“Fooling around with alternating current is just a waste of time. Nobody will use it, ever”.
Edison was fond of passing ridiculous arguments against his competitor George Westinghouse for AC power.
9. Impossible Flight of Machines Heavier than Air
“Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.”
This was predicted by Simon Newcomb. The prediction turned false when The Wright Brothers flew at Kitty hawk 18 months later.
10. Very Poor Energy by an Atom
Ernest Rutherford predicted that
“The energy produced by the breaking down of the atom is a very poor kind of thing”.
He gave his statement just after splitting the atom for the first time. He further stated that
“Anyone who expects a source of power from the transformation of these atoms is talking moonshine.”
11. Submarine will do Nothing
HG Wells was a British novelist. In 1901, he stated that
“I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea”.
Wish he was still alive to see how submarines are playing a role in defense of a country.
12. Automobile will Never Replace Horse
We can see how automobile has replaced horses. But in 1903, the president of Michigan Savings Bank advised Henry Ford’s lawyer not to invest in Ford Motor Co. According to him,
“The horse is here to stay but the automobile is only a novelty – a fad”.
This means he was not trusting on mechanical engineering at all.
13. Transmitting voice across the Atlantic
In 1913, Lee DeForest sold the stock of his Radio Telephone Company by making a prediction that
“It would be possible to transmit the human voice across the Atlantic before many years”.
14. People want to see flesh and blood
In 1916, Charlie Chaplin, the actor, producer, director and studio founder, stated that
“The cinema is little more than a fad. It’s canned drama. What audiences really want to see is flesh and blood on the stage”.
It has been proved that audience is more interested towards love stories
Water Powered Calculators and other devices have been around for quite some time now. Practical or not, these devices have been selling quite well as novelty products and business around the world have come up with innovative ideas and designs for them. I thought, It would be a great idea to make a list of all water powered calculators available in market. I did and then selected the top five of them for our readers. It has been a great 2 hour journey full of discovery and learning.
How does water powered calculator work?
Generally Two different metals have difference in electronegative charge. If we immerse them both in a fluid which has free floating ions (not pure water) then one metal electrode will preferentially attract ions causing a potential difference. If these metals are connected to an external circuit the process will create a very tiny amount of current in micro-amps range(Most calculator chips only require one or two micro-amps to operate). The process will run perpetually as the metal will continue to draw more ions from the solution until the fluid is exhausted or metal is fully oxidized. ( similar to a lemon battery)
The water is in fact not the source of the power. The electricity is produced by the difference in electrode potentials of the anode and the cathode which are inserted into the water (or potato/lemon). It’s just a battery, it looks a little bit different, but the clock draws a very small amount of current anyway. So in other words: the water powered calculators are actually powered by a dissolving of metals like zinc.
