Boeing has announced that it successfully conducted its first over-the-air ground test of a Ka-band satellite communications (SATCOM) phased-array antenna system that will enable wideband SATCOM on aircraft, providing increased bandwidth for networking in flight.This third-generation antenna system gives commercial and military aircraft operators worldwide the ability to offer communications using the growing fleet of commercial K- and Ka-band satellites.The low-profile antenna is also an option for government operators using military satellites such as the Wideband Global SATCOM (WGS) system.The active phased array system uses electronically controlled beams to transmit and receive signals from a designated satellite.The test demonstrated the new system's ability to support a range of applications, including file transfer and a Voice over Internet Protocol video conference. This Ka-band phased-array antenna system supports a significant increase in bandwidth with a smaller antenna than previous Ku-band antennas, still providing the same low profile, low drag, and lower cost of installation.

Actually this vehicle is like another bus, but more special than common bus because it can drive in the land and on the water.
England recently test an amphibians bus (Amphibious bus or amfibus) that can run on water or land. Buses with the framework of the Volvo brand was able to walk on water by using 2 machines that can be driven up to 8 knots, and while on the ground, can be operated as usual and can reach speeds of up to 100 km / hour.
The Amfibus seats up to 50 passengers and drives as a normal road vehicle as well as navigating waterways identical to a small vessel. In theory, the Amfibus is a one-stop-shop for seamless travel, removing the need for passengers to change modes at interchanges.This amphibious bus will be used to accelerate the time where most people have moved to the ferry and then continue again by bus and now it is not necessary.

In different regular speakers the sound produced will be focused in one direction. Glass speakers produce sound in all directions (360 °) and every part of the existing glass would produce different sound frequencies. These speakers appear to use glass as a resonator, creating 360 degrees of sound from flat glass. The base of each speaker can vibrate and the different areas of the glass slabs can create different frequencies of sounds, and hence a 360° of sound is produced.
Inspired by the ice of a glacier, the glass speakers even have the option of an added subwoofer.
With its shape alone, these speakers can beautify the interior room especially coupled with the backlight that will illuminate and change color, add cool for sure.These speakers can be used with wired or wireless system.You may one day see the window act as a speaker, too. Let’s just wait and see.

PepsiCo claims that it has developed the world's first polyethylene terephthalate (PET) plastic bottle made entirely from plant-based, fully renewable resources including switch grass, pine bark and corn husks. The bottle not only offers a significantly reduced carbon footprint compared to petroleum-based PET, but is also 100 percent recyclable.

The company says that by combining biological and chemical processes it has come up with a way to create a molecular structure that is identical to petroleum-based PET using plant-based materials, resulting in a bottle that looks and feels identical to current PET bottles. In the future, it hopes to expand the renewable resources used to create the bottles to include orange peels, potato peels, oat hulls and other agricultural byproducts from its food business.

PepsiCo says it will pilot production of the new bottle in 2012 and upon the expected successful completion of the pilot intends to move directly into full-scale commercialization.

Bacteria – and lots of them – are essential to the health and smooth functioning of the human body. Dirt, it is generally agreed, is a Bad Thing that may seem repellent, but without their contents, we would be in deep trouble. Every one of us is less human than we were on the day we were born. We emerged sterile into the world but, within minutes, were invaded by billions of bacteria. Those creatures still pass through in vast numbers. Each adult has ten times as many in their guts as they have cells of their own. Billions more live in the nooks and crannies of the skin, the mouth and elsewhere. We bear a kilogram’s worth of internal aliens. Every assembly is as unique as a fingerprint (and has been used by the police to see whose hands have been on a computer keyboard).

There are rules about who lives where. The forehead supports a community distinct from the arm, and the leg from the foot. Mouth and stomach are distinct and each has fewer types of bacterium than do other sites (for some reason, the back of the knee is particularly diverse).Such creatures are a forgotten organ, as essential as the liver. In the large intestine, they break down indigestible plant tissues for their own use – and make soluble chemicals soaked up by our guts. They also destroy harmful bacteria. Their chemical signals help the gut to develop and prime the immune system. Germ-free mice do not thrive: their immune system is feeble, their bowels do not move as they should, and they are generally unhealthy. Such animals are also anxious and obsessive. Our internal bacteria make plenty of the nerve transmitters associated with mood, and inner filthiness may even play a part in keeping us cheerful.
The developed world is in the midst of an attack of conditions in which the body’s defences fail to respond properly to external enemies. They include allergies, multiple sclerosis, juvenile onset diabetes and irritable bowel syndrome, in all which the immune system turns upon itself. Too much hygiene can be harmful

The Magenn Air Rotor System (MARS) is a new generation of cost effective wind turbine to produce electricity from wind power anywhere. Conventional wind turbines require wind speeds between 3 metres/sec and 28 metres/sec and are generally installed in coast line.As MARS can operate between 1 metre/sec and in excess of 28 metres/sec, they can be installed anywhere. The only restriction is that MARS units may not operate in controlled airspace or within five miles of the boundary of any airport.

MARS is a lighter-than-air tethered wind turbine that rotates about a horizontal axis in response to wind, generating electrical energy. This electrical energy is transferred down the 1000-foot tether for immediate use, or to a set of batteries for later use, or to the power grid. Helium sustains MARS and allows it to ascend to a higher altitude than traditional wind turbines. MARS captures the energy available in the 600 to 1000-foot low level and nocturnal jet streams that exist almost everywhere. MARS rotation also generates the "Magnus effect" which provides additional lift, keeps the MARS stabilized, and positions it within a very controlled and restricted location.

The Advantages of MARS over Conventional Wind Turbines: Wind Power Anywhere removes all placement limitations. Coast-line or off-shore locations are not necessary to capture higher speed winds. Reaching winds at 1,000-feet above ground level allow MARS to be installed closer to the grid. MARS is mobile and can be rapidly deployed, deflated, and redeployed without the need for towers or heavy cranes. MARS is bird and bat friendly with lower noise emissions and is capable of operating in a wider range of wind speeds - from 4 mph to greater than 60 mph.

MARS Target Markets: Mini-Grid applications in developing nations where infrastructure is limited or non-existent; off-grid combined wind and diesel solutions for island nations, farms, remote areas, cell towers, exploration equipment, backup power & water pumps for natural gas mines; rapid deployment diesel & wind solutions (to include airdrop) to disaster areas for power to emergency and medical equipment, water pumps; on-grid applications for farms, factories, remote communities; and wind farm deployments.

The only airport in the world to have a public road run across the runway is Gibraltar Airport. On the world map a small state called Gibraltar, is a self-governing British overseas territory located on the southern end of the Iberian Peninsula and Europe at the entrance of the Mediterranean overlooking the Strait of Gibraltar. The territory covers 6.843 square kilometers and shares a land border with Spain to the north. The Gibraltar Airport is 1,600 feet from the city, the shortest commute of any major airport in the world. British Gibraltar has very little area, and the important airport runway takes up a major portion of land. To drive from Gibraltar to Spain, vehicles must cross the runway.

The road in question, La Linea, is the one that goes from Spain to Gibraltar. In order to pass through, you have to cross the runway. There wasn't enough land to build a proper airport in Gibraltar from La Linea in Spain, so this one was built with the runways going across main traffic roads. Cars have to actually drive across the runway, and sometimes when the planes are setting off it seems like a very close encounter indeed

Well, to ensure everything runs smoothly, airport officials give warning to pedestrians and vehicles (in the same way as a level crossing would), but on a far greater scale. Operations shut down for 15 minutes and armed police gather around the British Naval base. Drivers and pedestrians wait until the plane goes past, then taxis the other way. Once the barriers open, you’re free to drive. The border between Gibraltar and Spain is always open for vehicles and pedestrians.

Renault has moved on with the bad experience it had with the Mahindra Renault Logan in India. Renault has sold off the Logan brand to Mahindra and decided to make its move in Indian on its own. As a part of its road map for India, Renault will launch the Renault Fluence sedan in India as early as June 2011. Renault Fluence will features luxury experience of the higher price segment cars like Volkswagen Jetta, Skoda Laura, Honda Accord etc.
In a price sensitive market like India, pricing a product in an attractive bracket may mean the difference between a sale and no-sale. The move of Renault to keep it competitive on pricing seems like a win-win situation for the buyers as well as sellers. Renault will benefit not only by selling more units, but also by creating the much needed presence on Indian roads. Getting to establish a brand which people recognize is not an easy job, which might get accomplished by this move.

The oceans are crucial to human survival and happiness. They absorb greenhouse gases like carbon, provide us with food and livelihoods, regulate the weather, and help us transport materials across the world, inspire some of our greatest art, and offer recreation to billions of people around the world each year.
The Mariana Trench i.e. a spot recognized as the Challenger Deep is the deepest known part of the world's oceans, and the deepest location on the surface of the Earth's crust. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2550 km (1580 miles) long but has a mean width of only 69 km (43 miles) and forms the boundary between two tectonic plates. At the bottom of the trench, where the plates meet, the water column above exerts a pressure of 108.6 MPa, over one thousand times the standard atmospheric pressure at sea level. It reaches a maximum depth of about 11,034 meters (36,201 feet) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end. Scientists have investigated the climate coverts of the deepest part of the ocean, i.e. the Mariana Trench, in the western Pacific Ocean. In order to study the bottom of the 10.9 km-deep underwater canyon, the international team used a submersible designed to hold up immense pressures. Their early results disclose that ocean trenches are acting as carbon sinks. This proposes that they play a greater role in regulating the Earth’s chemistry and climate than was originally perceived.
