Solar-powered plane is now flying and night
100 million Swiss francs ($92 million), the bulk of whom already have provided 60 co-sponsors, many players from major institutions and companies that support the draft celebrities, years of hard work … All came in a moving moment: sdernuto covered with apparatus, such which still did not know the history of aviation.

Swiss Solar Impulse project, introduced the audience ready machine HB-SIA (Solar Impulse Alpha) – the world’s first manned flight on solar energy, ability to remain in the air and at night.

Remember, the ultimate goal of this ambitious undertaking – the first manned flight around the world exclusively on solar energy. On the background and the start of the project, its key ideas we discussed back in 2003-m.

More detail design unique “drawn” in the 2007-meters, and are just now – Machine ready. But do not blame the Swiss for dolgostroy – they came to conquer heights, yet is not taken.

Yes, the planes were on krugosvetki, including nonstop. But – for fuel. Yes, there are airplanes that can lift the pilot into the air only by a single power solar panels deployed on the wings. But they are not able to hold in the air all night.

Finally, there are solar aircraft that can fly without landing during the day, the next night and again the day. But that – unmanned vehicles. And join all in one bottle was protected as easy.

Suppose that at noon on every square meter of the earth’s surface the sun befalls flow capacity of 1 kilowatt. But on average, per day, the capacity is only 250 watts per square meter.

In the light of wing area (approximately 200 squares), the efficiency of solar panels and converters for every 12% it turns out that average daily capacity of available non-unit – only 6 kilowatts, as the Wright brothers plane. However, he relied on fuel and total weight is nothing but a new car you need to carry a lot of batteries for night flight.

Only the incredible set of “imbalance” (the minimum weight in the giant wingspan, a delicate balance between the controllability and stability, and all that – while maintaining acceptable strength) may allow a person to fly in the sunlight. And Swiss managed to create such a device.

Solar Impulse has been officially submitted today, 26 June, the team led to their permanent leader, the famous traveler Pikkarom Bertrand (Bertrand Piccard). The presentation took place at the airport of Dübendorf near Zurich.

What got in the end?

When wingspan is almost 65 meters ( as a large Airbus) HB-SIA weighs only 1.6 tons, for which you want to thank carbon composites. In particular, carbon bar machine strong enough to withstand the elements of air, the thickness of them is the tenth of a millimeter.

On the wings spread Makhin 10 748 solar cells, and another 880 of such photovoltaic cells occupied the same horizontal surface of feathers. These cells are composed of single-crystal silicon just 130 micrometers thick. They are part of the wing and can bend in flight with him.

Night flying this machine provides a lithium-polymer batteries a total weight of 400 kilograms.

HB-SIA has yet to be the first time away from land (which is scheduled for this summer). Then followed a series of tests (fall) and, finally, the first manned “sunny” flight mode, day-night-day, that is – the world’s first human flight, without landing a duration of 36 hours only on the energy of light. This is probably already in the 2010-m.

But around the world this car does not fly. Tested on its decision Pikkara team intends to apply for the second Solar Impulse – HB-SIB, which should build in 2011. It will be noticeably larger and more powerful, with a sealed box (from the HB-SIA, she non-watertight) and better avionics than the first brother.

Here it is Pikkar and will in 2012 — m the first time, fly the Atlantic to the energy of light, a bit later – around the Earth.

Unfortunately, krugosvetka not get non-stop. Technically, Solar Impulse could fly non-stop for months at least, but everything depends on the physical possibility of the pilot.

The average speed in such a long flight (do not forget about the night phase, running on batteries energy accumulated during the previous day) was 46 km / h, explains Bertrand, and thus around the globe would have to fly for 20-25 days.

Meanwhile, up to man, do not leave the cab and running almost without sleep, this is 5 days. Weather and the autopilot will allow up to 15 minutes to 2 hours a day, explain the authors of the draft.

In fact, for greater security, are likely to be used four pieces. So the solar krugosvetku will perform a few large “jumps,” said the Swiss.

4-5 stops on the road to change will enable the pilot in the cockpit of solar device (Pikkar will alternate flights Borshbergom with Andre (Andre Borschberg), the second founder of Solar Impulse), and also – this will demonstrate the unique plane in different countries. So the real flight will take 4-5 months.

Krugosvetka it will gravitate to the equator, but most of the trip will take place in the Northern Hemisphere. Perhaps that Pikkar about Solar Impulse to repeat its surprising trip to the Breitling Orbiter 3: in 1999, Bertrand and Brian Jones (Brian Jones) made the world’s first successful nonstop krugosvetku on the hot air balloon.

Ten years of Swiss traveler has taken an important step to repeat the feat at the new spiral development of technology.

Intel will introduce the latest technologies in the Ukrainian education
The Ministry of Education and Intel Corporation will agree on applying the latest technologies in education.

This is stated in the press service of First Vice Prime Minister Alexander Turchynov, Ukrainian News reported.

First Vice-Premier meets with the Vice-President of Intel Corporation, John Davis, at which the parties discussed preparations for the signing of an agreement between the Ministry of Education and Intel, which provides a general introduction of the computerization of schools and relevant software in the educational process.

Turchynov confident that the joint program will quickly and effectively implemented.

“They will contribute to the qualitative change in attitudes to education and the transformation of world view in this regard”, – emphasized the First Vice-Premier.

The parties also discussed prospects for a joint ventures for the production of processors.

According to the press service of the Verkhovna Rada Committee on Science and Education, Davis, and Intel representatives also met with the head of Vladimir Polohalo, which Davis pointed out that Ukraine has all the prerequisites for the introduction of innovative projects, particularly in the sphere of education and expressed hope for fruitful cooperation with the committee.

This Polohalo invited interlocutors in the near future to form a specific directions and ways of cooperation, in particular, welcomed the opportunity to introduce to the Ukrainian student programs and competitions that are held corporation in other countries, the winners of which receive grants or scholarships to continue their studies abroad.

Chairman of the Committee also invited representatives of the company in Ukraine to start a pilot project targeted for teachers and students with computers and communications, modeled on those projects which are successfully operating in France, Italy, Portugal, Spain, Russia.

As reported, the corporation Intel – the world’s largest semiconductor company and manufacturer of x86-series microprocessors, processors for IBM-compatible personal computers.

Found the most uninhabited place on the ocean
Researchers from the University of Rhode Island took samples of rock ground almost in the center of the southern Pacific Ocean at a depth of four to six kilometers, and accidentally discovered, perhaps the most uninhabited place in the world’s oceans.

Of course, the comparison in this case is not with all the Earth’s oceans and their bottom, but only with the measurement made by people earlier.

started with a small expedition, organized D’Hondt oceanographer Steven (Steven D’Hondt), writes the membrane. He and colleagues burili soil and rocks were collected by cylindrical columns in a relatively quiet part of the ocean where the water contains a small amount of nutrients, there is no back flow, and above the little wind.

In one of the columns of all biologists counted a thousand living cells in one cubic centimeter sample. This is for three to four orders of magnitude smaller than in other sediments (note that in this part of the ocean, according to some sources, over a million years, growing only 8 cm bottom).

This discovery is curious, perhaps, only for the Guinness Book of Records, but D’Hondt makes an important observation: “Previously, scientists took samples near the coast, and felt that the data obtained can be extended to the entire ocean. Now it turns out that this is not quite right “.

Some of the microbes living in this part of the ocean, fed hydrogen atoms, which are formed during the decay of radioactive elements of the soil, which is corrupting the water ( rare process, it must be said, does not differ a great option).

Others relied, apparently, for organic remains, which descend from the surface to the ocean bottom.

“These data show that life can exist in damp rocks on Mars, or Europe. If micro-organisms adapted to such a poor place in the ocean, then and there as something kept “- D’Hondt said in a press release the University.

Article authors will be published in PNAS. In it the authors note that their research will continue and probably will be even more poor living organisms places.

Job taught to express emotions
In Japan the previous day was presented humanoid robot capable of expressing their emotions through gestures and facial expressions. Scientists at the University of Tokyo, have created a new bot, with one voice say that this instance – the first of its kind.

Miracle machine can express different emotions, including such as happiness, fear, surprise, sadness, anger and disgust, as the robot is able to open and close your eyes, move his lips and eyebrows, using hands and feet, reported Dni.ru. Robot hands are covered with soft material, which is supposed to copy the feeling of human hands. The body of the robot is set 48 different mechanisms, which cause his face and body in motion in different directions, the Internet TV Russia.ru.

Prof. Atsu Takinashi and his team spent development and establishment of the newest inventions of entire two and a half years. Professor Takinashi sure that “Kobian” – this is the first robot that can express all the emotions of the body. According to him, the ability to express their feelings is “an important factor in achieving communication between robots and human beings.” Professor is also hoped that such robots could be used in future to help the elderly in nursing homes, in the home and garden.

So far, the robot is still being experienced sample and does not interact with people. Professor Takinashi noted that it may take several decades before robots, such as “Kobian” may be used by people for their own purposes. In the future, scientists hope to create such a robot, which will ultimately think and behave the same way as people.

Remember that Japan is considered the birthplace of robotics. This sector of the economy of the country of Rising Sun is estimated at 10 billion dollars. Every year here collect 800 thousand robots for various industries. The main objective of development is the maximum reduction in the use of human labor in the production with the rapid growth of middle-aged people, say Vesti.Ru.

Shuttle proved the existence of Tunguska meteorite
U.S. scientists have found yet another proof that the Tunguska meteorite explosion was the result of a meeting of Earth comet nucleus. This was reported in the press release, Cornell University, who participated in the work, a paper appeared in the scientific journal Geophysical Research Letters.

As part of the work of researchers interested in the so-called mezosfernye ( mesosphere – region of the atmosphere at an altitude of 50-90 km) clouds, which are clearly visible at night and occur in latitudes between 50 and 60 degrees north or south latitude. They represent an accumulation of ice crystals formed at a height of over 85 kilometers at a low temperature.

The researchers found that mezosfernye cloud sometimes observed after the launch of shuttle: Similar cases have been recorded in 1997, 2003 and 2007. According to researchers, the clouds are the result of the fact that during the shuttle launch in the thermosphere (the atmosphere at altitudes from 90 to 800 kilometers) emitted about 300 tons of water vapor. From there it enters the vapor mesosphere, where the clouds are formed.

The researchers examined the historical evidence of the “sky glow”, which occurred after the fall of Tunguska meteorite in 1908. Experts have suggested that light is a just mezosfernye cloud formed after the destruction of ice, which was the nucleus of a comet, in the upper atmosphere.

The only thing not yet explained by scientists the case of the shuttle launch – this is a mechanism that not dispels the clouds of steam, and moves them “unharmed” by a considerable distance, the Lenta.ru. The point is that Cape Canaveral is located at a latitude below 30 degrees and the clouds mezosfernye, as mentioned above, is not observed at latitudes below 50 degrees. Tunguska meteorite explosion occurred just above the 60 parallel.

Researchers suggest that the transfer of a pair may be responsible turbulent flows. Experts estimate that the rate of particle transport water should be about 100 meters per second.

Tunguska meteorite is one of the biggest mysteries of the XX century. Jun 17, 1908 in the area of the river Podkamennaya Tunguska explosion occurred on the capacity of 10-40 megatons. Blast was registered in observatories around the world. There are currently dominated by the hypothesis that this event was the result of an explosion above the Earth’s surface the cometary nucleus.

RapidShare is not fined
Court of Hamburg did not penalize German RapidShare file hosting for 24 million euros. This amount was only evaluated pirated music tracks featured on the service and become a cause of action by the organization GEMA. Lenta.ru reported with reference to TorrentFreak.

First TorrentFreak reported that the court fined RapidShare. However, later published a rebuttal of the publication, which describes the permitted error.

Court acknowledged hosting RapidShare held responsible for the content on its servers and need to remove five thousand music tracks that violate copyrights. In addition, the court ordered the RapidShare does not allow re-download these tracks and test the legality of all files downloaded by users.

GEMA is a German organization for collecting royalties. It represents the interests of 60 thousand composers, authors and record labels.

RapidShare is one of the largest file-hosting the world. At its servers located in Germany, kept millions of files. In April 2008, RapidShare has a system of data storage with total capacity of 5.4 petabyte.

A telephone for very young children
In Europe, a mobile phone designed for children four years. Bright unit with a mind more like a toy, but it is not so little: a novelty in the UK will be sold at 85 pounds, which is almost 140 dollars.

A strong device under called Firefly ( “Firefly”), all five buttons, two of which are intended to call my mother and father, says The Daily Mail. In Ireland, the phone has already entered the market, bought more than 7 thousand.

Parents may prohibit a child to take calls from unknown numbers and to control who is listed in his contact list, notes manufacturers. Some models do not allow to write SMS, said Newsru.

Currently, half of British children aged under ten years old have mobile phones, recent studies show. Cell has 85% of adolescents (10 to 14 years).

Manufacturers phones aimed at new customers

“We are constantly destroying children’s lives and turn children into miniature adults – explains the emergence of a new development representative group Parents Outloud Margaret Morrissi. – Justifies the fact that this is done for security reasons, but in reality it is necessary to increase the income of companies that produce mobile phones “.

Professor Laurie Chellis, who led a government study on the safety of cellular communication, argues that mladsheklassnikam generally contraindicated use phones. To lower the radiation affecting the health of children, it is better to write SMS, and not to call, says an expert.

Since British scientists agree, and Chief State Sanitary Doctor of Russia Gennady Onishchenko. He recommends that the Russians limited the use of mobile phones because they are bad influence on the brain.

Eni Lynch, head of the National Parent Council of Ireland, expressed concern that the manufacturers of phones aimed at children. “Why should communicate with their children on a mobile phone? Why not look for them, parents, teachers or carers? “- She wonders.

The British Government recommends not to buy mobile phones to children under 16 years of age. In some countries proposed more stringent measures. Thus, France is preparing to adopt a law prohibiting selling mobile children up to six years and prohibiting the advertisement of phones for children under 12. At the end of last year in Japan also offered to ban mobile phones in schools.

Students downloaded porn in the educational program
In some schools Ukhta internet, as it turned out, not always used for training purposes. After verification of educational institutions, which held a prosecutor’s office Ukhta and specialists the department “K” on the Ministry of Internal Affairs Committee, it became clear that educational institutions have violated the law in implementing the national project “Education” on “Informatization of Education”.

Because of the lack of filtering programs on computers, students received free access to Internet resources, inconsistent with the objectives of the upbringing and education of minors, said agency Kominform “.

Put simply, students lazili on the Internet sites of erotic and pornographic content. “shocking was the fact that on one computer cabinet Informatics review educational institutions were found pornographic movie. This is science, even the teacher did not know that such a file is stored on any computer and is available to any user, “- told the prosecutor’s office.

Also, on computers in science classrooms tested Schools were established gaming software that is not related to the learning process: the most common was the game Counter Strike, said Newsru.

Also, the audit found that controls over the use of the Internet in educational purposes in schools not maintained, the account of the use of the network, and also visited Internet resources is not being implemented.

According to the results of verification activities Ukhta prosecutor’s office has made a submission to the administration of educational institutions, the Chief Department of Education administration of urban districts.
