Electricity invited to be produced from the ominous air.

Electricity can be obtained in the literal sense of the air. However, just before the storm, and only if we can bring to the practical realization of the idea of Brazilian Professor Fernando Galembeka.

At the 240 th annual meeting of the American Chemical Society, held Aug. 25 in Boston, Galembek, whose scientific interests lie in the field of physical chemistry, said that a series of experiments, the results of which theoretically could be used to generate electricity.

Utilization of atmospheric electricity (already named "gigroelektrichestvo" that is literally "wet electricity") would like to compete with traditional power plants, and help in solving the problem of lightning protection. Instead, to keep off the ground level to install lightning rods and special tools for protecting electrical circuits, one would simply eliminate the very reason for the appearance of lightning near a protected object. At least, if we follow the proposal sounded Galembekom.How it works?

To view the details of the experiments can be a scientist in the article, available on the website of the American Chemical Society. Writes Galembek, its installation was relatively simple and consisted of two metal cylinders inserted into each other and placed inside the grounded chamber, where air was supplied with a strictly defined humidity.

Aluminum used in the experiment on the moist air can quickly become covered with a thick layer of oxide and is, at least, can reduce the performance of the installation (the maximum-attack to destroy the unit). Were intact same battery sandpaper on a regular basis! In describing the experience of states that the working surfaces were carefully polished and is cleaned with alcohol, again, unrealistic condition for large-scale industrial installations.

About how much really using electrochemical devices to prevent the appearance of lightning, too, yet difficult to say, especially since many of lightning do not occur in the lower atmosphere, and between the middle of thundercloud and the ground (although some lightning strikes, and did up the stratosphere). Do not throw in the same storm clouds cumbersome installation much easier it is to use the used reagents to induce rain clouds of sufficiently mature! Physical chemistry

Physical Chemistry, which deals with Galembek, explores the chemical processes which can not all be reduced simply to the interaction of molecules and their transformation into each other.Wherever you want to take into account the emergence of electric current or charge transport material flows of fluid or gas, which refers to the acquisition of new properties of matter when it is grinding to microscopic particles must involve physical chemistry.

Facebook more than Yahoo!

 


Shares of the largest in the world by number of users of social network Facebook is rapidly growing in price. Investors rush to buy them in advance out of the company at the exchange.

Now Facebook shares are traded only on the secondary market . Based on current prices ($ 76 per ordinary share) the cost of the entire company at $ 33.7 billion, although in June an American investment fund Elevation Partners acquired its shares, based on an assessment of 100% to $ 24 billion A Russian Digital Sky Technologies, Meeting on 10% Facebook in May 2009 are estimated its total to $ 10 billion

Now Facebook passes on the cost of such giants of Internet business, as eBay and Yahoo!.

Investors rush to buy shares of Facebook before she applied for a IPO. Analysts expect the IPO Facebook will be the largest deployment in the IT-market since 2004, when a public company became Google. However, this does not happen before 2012, made it clear itself Facebook.

Its employees and stockholders may sell their existing shares on the secondary market, and many use it. True, Facebook is trying to limit the scope of the trade: the law of its shareholders may not exceed 500. So far, according to informed sources, their much smaller, however the company is buying up part of the paper itself or delegate this right to existing co-owners such as Tiger Global.

Current quotes sources close to Facebook, consider excessive. The appeal is only a small number of shares, while investors do not even have a clear idea of the financial performance of the company, they explain. 

Facebook - a social network. ASOA has more than 500 million accounts.The co -owner the founder of the company ,headed by Mark Zukerberk and its employees ,the american billionaire Peter Theil ,Accel Parteners ,Microsoft ,Digital Sky Technology .Revenue (2010, forecast Facebook) - $ 1-1,1 billion

Hollywood actor has appeared in advertising automobile oil Gazpromneft

 

Experts believe that with the name the actor is more than the sale will pay for the costs of the company.

Jason Statham is known for his roles in "The Transporter", "Adrenaline", "irresistible", and also works in the paintings of Guy Ritchie Lock, Stock and Two Smoking Barrels "and" Snatch ". Gazpromneft called the actor to shoot a clip to promote a new brand of the company - lube G-Energy. According to film producer Alexander Izotov, it's a good publicity stunt:

"Knowing Alexander Dyukov, the head of Gazpromneft, as a very creative, I'm not surprised that they invited so untwisted star fighters to advertise their product. This is an interesting and important word in advertising.

When selecting media character, it is important to consider not only his popularity, but also the extent to which people close to the people for whom the product is calculated. And in this case, getting more than accurate, I am sure the head of media practice of "Paynz End Merner Roman Tyshkovsky:

"Oils are buying men who own cars. These people tend to like films about race, militants. Here, from this point of view, quite correctly guessed the target audience. They know this person, so it has a certain credibility. To a man, who rides fast, which makes extensive use of machinery, he leads an active lifestyle, so they advertised product in the consumer's mind will be associated with the speed and adrenaline.

How Statham received for shooting in the video is not known. According to the Portal Life News, the actor's fee amounted to 100,000 euros. Two shooting days - in Moscow and the Czech Republic. By advertising standards, this is not a record amount, said Alexander Izotov:

"If this is true, it is the success of advertising managers Gazpromneft or agency that serves them. I think that this actor is more expensive. By some, perhaps, the reasons for such an amount of 100 thousand euros illuminated. But I think that figure should be much greater. "

Other celebrities who starred in the Russian advertising, earn more. For example, in 2006 in the video about the ketchup "Baltimore" played by Gerard Depardieu. According to the scenario he was eating his own hat. The fee amounted to 250 thousand dollars. . How, then, to write press, the athlete received 300 thousand dollars. A year later, one million dollars for participating in the campaign of vodka "Russian Ice" earned Sylvester Stallone.

No options

After the break, the situation at Anfield has become even more complicated: Carlos Tevez, like a devil from a snuff-box popped up in front of Pepe Reina and the slight movement of the foot correcting the trajectory of stroke Mickey Richards - 2:0.

Having admitted the second goal, "red" unexpectedly took heart and laid siege to the approaches to kick an opponent. In Steven Gerrard hit the bar gate Hart, and after two minutes the hosts had saved a tremendous response of the young goalkeeper Joe Hart, otbivshego two strikes in a row.

Having missed the opportunity to immediately otkvitat one ball, the players Liverpool snikli and soon missed another goal.

Main attitude

After the game head coach of the "City" Roberto Mancini said that he was particularly pleased to win in front of the club owner Sheikh Mansour.

"I am pleased that was able to show that [Sheikh Mansour] good game, which was so important - the coach said Manchester City." - The main thing for us was, do not choose a strategy, and tune into the game. Our victory depends on the mood.

Roy Hodgson, who led Liverpool before the start of this season, said that his team still did not deserve defeat such a bill.

"But we played poorly on defense, passing such goals, - admitted the coach. - They also made good use of their chances."

Besides the coach of "red" noted the game rival, saying that "Manchester City played a strong and confident throughout the match.
