Combating Global Warming: Turning Earth Into a Planet-bright White

Combating Global Warming: Turning Earth Into a Planet-bright White

Scientists have envisioned a project that involves combat global warming by reflecting sunlight.

Combating global warming: turning Earth into a planet-bright white
   The project aims to gradually replace materials currently used for building roofs and roads white or light materials. Thus, say the creators of the phenomenon of reflection of sunlight, called albedo, would provide significant cooling, which, over 50 years would be equivalent to a 25 or even 125 billion tons of carbon dioxide.
Sidewalks and roofs are in May than 60% in urban areas, and they are responsible for attracting solar energy and creating hot spots. Called heat islands, cities are consuming power and producing smog, a phenomenon that involves high costs in health care.

InfoNews: France unveils secret UFO - Franta isi dezvaluie s...

France unveils secret UFO
The French state became the world leader after he agreed to release more than 1,600 files on UFO sightings secret information in the last 50 years in mainland France. French space agency joins his counterparts in Britain and Russia in an effort to shed light on these mysteries, Pravda announced.
Information posted on a website including but he gave after huge number of visitors. Of the over 1,600 cases, about 25% are part of "Class D" category were included unexplained cases whose veracity can not be denied. Information provided by the French authorities over a stretch for more than five decades, from 1954 to date, and include both data and photographs of unidentified flying objects and the alleged alien entities. Source: Pravda
Romanian language:
Statul francez a devenit lider la nivel mondial dupa ce a acceptat sa faca publice peste 1600 de dosare secrete cu informatii privind aparitiile OZN din ultimii 50 de ani de pe teritoriul Frantei. Agentia spatiala franceza se alatura astfel omologilor sai din Marea Britanie si Rusia in efortul de a face lumina asupra acestor mistere, anunta Pravda.
Informatiile au fost postate inclusiv pe un site web dar acesta a cedat in urma numarul urias de vizitatori. Din cele peste 1600 de dosare, aproximativ 25 % fac parte din „Clasa D”, categorie in care au fost incluse cazurile inexplicabile a caror veridicitate nu poate fi negata. Informatiile puse la dispozitie de autoritatile franceze se intind pe o perioada de timp de peste cinci decenii, incepand cu 1954 si pana in prezent, si cuprind date si fotografii atat ale obiectelor zburatoare neidentificate cat si ale unor presupuse entitati extraterestre.

InfoNews: How To Choose A Home Theater System

When choosing a home theater system one must first consider there budget. In years past a home theater system was for only the rich, but with improvements in technology, home theater system are available for almost any budget.


Costs range from $299 to $30,000 or more, depending on the components chosen and the size of your home theater system.




Components


Most people try to achieve creating a movie theater in there home. Now of days a most theaters have surround sound system. Therefore in a home theater you will want to look for the following components, a large-screen television (usually 32" or larger), and a speaker system with a subwoofer (a loud speaker designed to reproduce bass frequencies) & front and rear (usually a minimum of 5 speakers) speakers for quality sound. You will also need an audio/video surround receiver, a DVD player, and a cable or satellite receiver. Most people also add a video recorder and a DVD recorder.




The big screen television


High-definition television (HDTV) is the most popular for Home theater systems. HDTV's digital technologies give a much sharper & crisper picture quality, also an improved video field to bring the audience right into the middle of the action.


One of the things you must consider when you design your theater system is to look to the future. This way your system will stay up to date longer. To do this you will need to consider things like purchasing a high-quality, integrated HDTV monitor with wide screen display, because the conventional full screen movies we have enjoyed for years will someday be replaced with the movie theater style wide screen movies that more and more we are enjoying now. Even cable systems are delivering digital viewing services, which will only continue to develop.


Wide-screen HDTV monitors start at 27" for a traditional square shape and 30" for a wide-screen, and range up to 82".


When considering a televisison for a smaller area you may want to look at direct-view televisions. For larger areas you can consider rear-projection or plasma televisions, Direct-view televisions don't require viewers to sit so far back from the viewing screen.




Surround-sound


Remember when considering your home theater system that sound is a very important part of the experience. You can buy a box system for as little as $200. You will want to look at different system and choose the one that best fit your needs and the sound quality that best fit you space and needs.


Dolby Digital 5.1 surround sound has been the industry standard for years, says Craig Eggers, director of consumer electronics technology marketing for Dolby Laboratories. Dolby is now the North American audio standard for HDTV. This technology "delivers 5.1 channels of fully discrete surround sound audio to any home theater," Eggers says. This means the soundtracks are recorded with five main channels: left, center, right, left surround and right surround, plus a low-frequency effects bass channel.
Surround sound systems use a minimum of five speakers to bring the listener inside the viewing experience. Instead of watching the picture, you're a participant--just like at a movie theater.


These box systems also include various components such as DVD players or recorders, or am fm stereo, VCR players or recorders, some system may also include iPod or Mp3 technology.


This will complete the basic systems, but don't forget that you may also want to consider a camcorder or digital camera technology for those home videos.


Once you have developed the home theater that best fits your needs the only thing left is to sit back and enjoy and don't forget the popcorn.




How-To Tips
Cables are an integral part of a home theater. Good cables will enhance the performance of your entire system, while poor quality cables can actually reduce quality. Look for the following when cable shopping:
· Look for cables with high-density shielding, gold-plated connectors and durable jackets to provide long-lasting, reliable connections. If you have the choice of using either digital or analog cables, choose digital to eliminate unneeded digital-to-analog and analog-to-digital conversions, which lead to reduced image and sound quality.
· When you're looking for the right cables, make sure you avoid generic cables made with low-grade materials and low-quality construction because they're highly prone to noise and distortion. Watch especially for connectors that fit loose or too tight, with inadequate shielding and unprotected solder joints.
· Be wary of manufacturers that don't provide information concerning the construction of their cables. Quality cable companies, such as Accell or Monster Cable, often will provide a cable cut-away illustration, providing clear visibility of their cables' material and construction.
· Finally, make sure to keep your cable lengths as short as possible to get the best quality sound.

Top 10: Future Weapons


Top 10: Future Weapons
Despite its claims to the species evolved and superior compared to other living organisms with which it shares the planet, man gave up the idea of war at all. On the contrary even, helped by galloping technology, is preparing to launch a new generation of deadly weapons, whose potential is higher even deadly weapons invented by science fiction authors famous sites.
Restless minds thought in secret laboratories of the armed forces belonging to the great powers, weapons XXI century promise to emulate the power to destroy all instruments of death invented by mankind so far.

10. Information War

New information technologies will have on the battle front as direct target flow of information on enemy operations. At the same time, attempts will be to protect intelligence and communication channels such piracy in the country due , and of its allies.
How they work: Information war specifically targeting communication networks and computers.Hackers experts employed by any self-respecting army - and called crackers - their mission to break the codes and passwords that protect computers and networks enemy, to steal information or spread viruses it very difficult to eliminate. Departments of jamming, interception of the future will benefit from technologies armies in November , held in secret, with which can block the TV or radio communications immediately. Misinformation can move so freely.
Limitations: as a prime example, the U.S. military relies on computers and communications in Maythan any other army in the world. Thus, it can have an extremely powerful weapon, but very vulnerable and can turn against them at any time .
In addition, as proved last confrontation in Iraq and Afghanistan, is completely ineffective information war against opponents who do not give a shit about technology.

9. Missile defense systems

Even today, overlapping sets of missiles offers the best protection in a ballistic missile attack. In future, these instruments of death, derived from the famous "Stalin's organs", which have sown death during the Second World War, will be equipped with high performance sensors, which will increase, at least in theory, effective to the extent that they can eliminate any threat of rockets.
How they work: multiple missile systems will be programmed to destroy enemy missiles in three different situations:
1. In the initial phase - start - a ballistic missile when its engines ignite and thus can be easily identified after thermal footprint.
2. In the continental missile to target the race
in March. In the finals, when he crossed the border country and is preparing to make contact with the target.
Each of the stages require different technologies for the destruction of enemy missile to be destroyed in due time.
Limitations: missile batteries success depends on the efficiency with which they can intercept the enemy missile destruction in the three phases mentioned. Such a missile program is extremely expensive; build from; therefore costs, location, testing and service are unbearable even by a rich country. Although the destruction in the first phase is the most effective anti-missile system is very inefficient in case of attacks from different geographical areas or of successive volleys of rockets that do not allow time to muster and identification.

8. Weapons based on very strong microwave frequencies (best known as e-bombs)

A powerful weapon capable of emitting microwave beams can "fry", literally, computers, electronics and electrical appliances of the enemy. This kind of weapons there are currently many armed forces having their direction component of microwave weapons. (Not to be confused, however, military information technologies described above.) Communications systems can easily destroy military and civilian are a breeze for such a device.
How they work: a strong electromagnetic field enhancement will be further transformed into a focused microwave flux. Flow will be routed directly to the target that needs to be destroyed, be it tank destroyers, aircraft, helicopter or car transport. Flow burn, simply electrical and electronic equipment, making it unusable enemy weapons. In particular, electrical semiconductors are very sensitive to a "bombardment" microwave. Special bombs generate the strongest flows, able to cover large areas, but smaller generators attached to the aircraft or helicopters can accurately identify targets, a tank can easily incapacity or an enemy plane.
Limitations: effects depend on the configuration and conditions on the battlefield is difficult to predict. Sensitive military equipment of the enemy can also be protected by energy shields, and a microwave flow against them can be easily diverted aggressor even in camp.

7. Guns on power

It all started in the '80s, with the advent of market self-defense items electroshock devices. Small devices, commonly called "Taser" or "shock", soon came to the attention of military strategists, who were thought to produce electroshock devices the size of a cannon.
How they work: special mechanism equipped with a cannon will shoot arrows equipped with electric cables. The weapon can burn the electrical installation of an enemy tank or can be used on groups of soldiers from enemy assault troops. In this case, it is necessary, of course, an adaptation of the weapon. Electrical pulse passes through the human body temporarily voluntary control of muscles, leading to the capture of a large number of prisoners.
Limitations: people who are victims of a Taser can be quite serious injuries when they fall to the ground, no longer any control over their own bodies. Arrows can hurt your neck, eyes or genitals.Death can occur easily in cases where power is not adjusted properly taserelor view.

6. Nuclear missiles

Probably the most dangerous weapons at hand man, missiles with nuclear warheads with a destructive power unmatched by any other weapon.
How they work: one or more nuclear warheads will be mounted on a ballistic missile, which is then launched vertically. Rocket can be high up in the upper atmosphere, and will be guided from the ground or from space directly to the destination set, which will explode with effects often incalculable.Obviously, in the future, technology will produce guidance and control systems more advanced than today, which will increase efficiency and missiles with nuclear warheads danger.
Limitations: These weapons are so terrible and destructive, that is unlikely to be used in war. In addition, instead of launching a nuclear missile trajectory and can be identified almost instantaneously by enemies, which can replicate, in turn, with nuclear missiles. Obviously, if a nuclear war there will be no winners or losers, in fact, considering the almost incalculable damage the ability of new nuclear missiles, it seems that there would be no life form on Earth, after such a apocalyptic scenario.

5. Active Denial System (also known as millimeter wave weapon term)

Rays and microwave beams were created in order to disperse people protesting violently without cause them harm. Most police forces in the world possess such weapons, machines attached to the ground.
How they work: in the context of large-scale military confrontation, will produce enlarged replicas of these weapons, which will be attached to military vehicles "ametirii" enemy soldiers. A 2 meter long antenna and a mobile generator that produces the beam of radiation with frequency of 95 gigahertz (wavelength = approx. 3 mm) will be easily attached to land tanks and cars. Typically, about 0.3 mm layer of human skin will absorb the radiation, which will cause intense pain in the first 5 seconds of exposure.
People will flee immediately, if they could ...
Such a "ray of death "can immobilize, literally, the group of people on whom it is directed.
Limitations: if people fail to come to the time of the beam range can be chosen with serious injuries or even death can occur. Human skin is burned awful if such visits the beam on to more than 1-2 minutes.
beam overheating and metal objects carried by people, such as rings, wedding bands, jewelry, coins or weapons, leading to amplification of heartburn.

4. Air Force hypersonic (or scramjet famous sites)

A fighter will exceed class hypersonic Mach 5 - five times the speed of sound - with the ability to hit any target on earth within a less than two hours. It will also be able to launch a satellite into orbit Earth.
How will it work: to take off, a hypersonic aircraft will be attached to another aircraft or will be equipped with its own engine and tanks to allow him off the ground and achieve those amazing speeds. The engine will be able to transport plane at high altitude, where air density and the resistance is lower. From that altitude, the aircraft will be able to reach hypersonic speeds, and then can pass the type scramjet engine.
Limitations: technology to create a super-plane is also in an early stage of development, with many technical problems still unresolved. Scramjet engine can not start until after the plane broke the speed of sound. In addition, hypersonic flights were demonstrated only through prototype unmanned aircraft, which were transported at high speed at high altitudes by other aircraft. Until now, hypersonic prototypes are too small to carry a pilot.

3. Space Weapons

Space remains the last territory conquered, so future extra-orbital weapons will be able to identify and destroy targets not only on Earth but also those located in space.
How they work: The main mission of space weapons will be to provide protection in situations of ballistic missile strikes directed against targets on Earth. Fleets of interceptors, with battle stations, continue to remain on orbit for the express purpose of drawing on ballistic missiles.
Limitations: functional technology to such weapons is still in its infancy. Reaction times should be very short. Interceptors must identify and destroy missiles in time, which is extremely difficult. Laser technologies need chemical fuels or electricity to function optimally, it is still impossible in conditions of space.

2. High power lasers

This type of lasers used for military purposes, are powerful rays that penetrate the distances from Earth or space in a straight line fine. Laser beam moving at lightning speed and can hit instantly at distances of thousands of kilometers.
How they work: giant-sized mirrors will focus powerful laser beams on small points of target. Heat produced in this way will be so strong that will produce fuel surface targets. This translates into the destruction of missile warheads, military aircraft or tank explosion and ground bunkers.
Limitations: for a laser to be effective in combat, it takes huge amounts of energy production.Targets can be destroyed almost instantly, with less expense, with missiles, torpedoes and other projects. Powerful lasers, driven by electricity or fuel, are enormous, which is already a major impediment in the current military conflict.
For example, the U.S. Airborne Laser fits only in the impressive size of a Boeing 747 aircraft. Also, transport by air turbulence can disperse energy inherent in the laser beam.

1. Autonomous weapons

Are, in fact, robotic vehicles, still in experimental phase, from which is expected to destroy enemy troops, plus military ground and air, without risk of human losses
How they work: integrated onboard computer robots will interpret the information received from sensors, in order to identify targets and hostile forces. Human control robots will wait before he shoots the enemy or will have some degree of autonomy in decision allowing them to choose when they will attack targets.
military robots will be able to identify and protect allied troops or soldiers and local devices.
Limitations: Currently, cybernetics and robotics great difficulty in setting up programs through which military robots can distinguish between Allied troops and enemy troops and civilians or between different objectives, animals or other moving targets.
Control systems managed by people are still vulnerable to failures of transmission.
There is a risk, very obvious, like a robot with defects, whether even minor, to pull out of control or discrimination of any targets.
