Kona Nigari water

Water is no more just water. People pay money for water every day, even though it’s free in the majority of places on Earth. So if we’re already paying for it and shelling out big bucks in some cases, why not pay a lot for it, right?
This luxury priced water called Kona Nigari is desalinated water high in minerals found 2,000 feet down off the coast of Hawaii. This brand of bottled water sells for an eye popping $33.50 per two-ounce bottle of concentrate and is meant to be diluted in a bottle of regular water (add $1.99 to the bill).
It’s credited with aiding weight loss, stress reduction, skin tone, and digestion. And apparently this Hawaiian seawater is special — people pay more for the Kona Nigari. This seawater is so lucrative that the Hawaiian government is now allowing bottlers to use a state-certified logo for their deep seawater for a nominal fee.
So, where are the customers for this pricey water? Just to let you know, 80,000 bottles are shipped to Japan every day. Hypothetically speaking, there will come a time when people will think twice before drinking water as it may cost you a bomb, to be precise $2144 per gallon only if the Kona Nigari water becomes a world wide rage!

Operation Odyssey Dawn

The Libya invasion has been named Operation Odyssey Dawn. Western coalition forces have launched a devastating attack on Libyan defence sites in and around the country, letting of at least 112 Tomahawk missiles from two submarines, one a US and the other a British which have been lurking on the shores of this North African country. The attack was announced by the Pentagon. It said more than 20 Libyan air defense systems on or near the coast had been struck. The 112 Tomahawk missiles were used in the attack on air-defense systems, which is the first stage of the allied operation, designed to suppress and degrade radar systems and surface-to-air missile sites in order to secure control of the airspace and reduce the threat to planes.

Tomahawk is an all-weather submarine or ship-launched land-attack cruise missile. After launch, a solid propellant propels the missile until a small turbofan engine takes over for the cruise portion of flight. Tomahawk is a highly survivable weapon. Radar detection is difficult because of the missile's small cross-section, low altitude flight. Similarly, infrared detection is difficult because the turbofan engine emits little heat. Systems include Global Positioning System (GPS) receiver; an upgrade of the optical Digital Scene Matching Area Correlation (DSMAC) system; Time of Arrival (TOA) control, and improved 402 turbo engines. The hallmark of a cruise missile is its incredible accuracy. It can fly 1,000 miles and hit a target the size of a single-car garage.

Guoliang Tunnel- Road that does not tolerate any mistakes

This road is located in the Taihana Mountains in the Hunan Province of China and before its construction in 1972, access to Guoliana village was restricted to a treacherous path carved into the mountain face. Surround by soaring mountains the village of Guoliana was essentially disconnected from all civilization! However, in 1972 a group of men from the village decided to take matters into their own hands and began carving a road directly through the mountain all by themselves! The project was led by the ‘head of the village’; Shen Minaxin who insisted this immense undertaking was embraced by all in the village. Due to Shen’s insistence, the villagers funded the procurement of hammers and steel tools through the sale of goats and herbs and after 5 years the tunnel was complete. All by hand they had completed a 1200 meter long, 5 meter high and 4 meter wide tunnel right through the imposing mountain. This huge feat of engineering was not only laborious and physically demanding but dangerous as well with a number of villagers being killed during its construction. Despite being carved totally by hand, the tunnel was completed and opened to traffic for the first time on 1st May 1977.

More than 30 windows span the length of the tunnel and it is thought that these may have been produced to expel rubble during construction as well as supply light due to the lack of electricity in this remote mountainous region. It is only in recent times, with the opening of China’s borders to tourists that the villager’s hard work has paid off. Before the tunnel was constructed the only way out of the village was via a ladder up a sheer mountainside but now with the influx of tourism, Guoliang Village is thriving and is now considered another jewel in the crown of the Taihang Mountains.

Jet pack - Reality from science fiction

Jet pack, rocket belt, rocket pack, and similar names, are various types of device, usually worn on the back, that use jets of escaping gases (or in some cases liquid water) to allow a single user to fly. It is a personal aircraft that requires minimal training with a goal to create a Segway for the sky, where the principles of flying would be very simple .
The concept of these devices emerged from science fiction in the 1920s and popularised in the 1960s as the technology became a reality. Currently, the only practical use of the jet pack has been extra-vehicular activity for astronauts. Despite decades of advancement in the technology, the challenges of Earth's atmosphere, Earth's gravity, and the human body (which is not well suited for this type of flight) remain an obstacle to its potential use in the military and as a means of personal transport. There's a lot more engineering in it than one might perceive. The key problem has been what is called the "weight-to-thrust" ratio, which basically boils down to the conundrum that the heavier you are or the longer you want to stay in the air, the more power you need, which in turn means you have to carry more weight. It’s been a long time coming, but the future is here! Finally we can all take flight as Martin Aircraft in New Zealand releases the first commercially-available jet pack!

Biome Concept of Mercedes-Benz Sport Cars

Mercedes-Benz has spawned with the BIOME – one of the most outlandish and ambitious concepts in Los Angeles Design Challenge where many saw them and feel it’s like the car of Star Trek. Mercedes comes with the brand and product name of Mercedes Benz Biome. The Biome is meant to blend seamlessly into the planet’s ecosystem. That means all components of the Mercedes-Benz Sport Cars Biome Concept car are “grown” organically, and it emits pure oxygen and is completely biodegradable at the end of its service life. The car designs in such a way where 4 passengers sit at a time inside. The Mercedes Benz Biome car has the great internal dynamic interior which looks so elegant and attracting for the die hard car lovers. Mercedes said on about their new Mercedes Biome Car that this car is not made in a conventional way; it is distinctive in term of all features and design than other cars. Mercedes said that the Biome made genetically by the customized trees and power of some unbelievable which they called as Bio Nectar 4534. The car outer body is bio fiber cloth body which produces the oxygen in the environment. This material is significantly lighter than metal or plastic, yet more robust than steel. Bio fiber is grown from proprietary DNA in the Mercedes-Benz nursery, where it collects energy from the sun and stores it in a liquid chemical bond called BioNectar4534. Mercedes Biome is genetically built or construct car which change the perspective of conventional cars around the world.

The car is also a solar collector. It’s designed to work like a leaf, and absorb solar energy while you’re out and driving about. The result? That’s what would power the vehicle, mostly. Other details about the vehicle are still anyone’s guess, but with what have already known, we are already starting to count down the days until the Biome becomes the real deal.

In short, the BIOME would be grown in a lab rather than built on a production line.
"As the inventor of the motor car, we wanted to illustrate the vision of the perfect vehicle of the future, which is created and functions in complete symbiosis with nature. The Mercedes-Benz BIOME is a natural technology hybrid, and forms part of our earth's ecosystem. It grows and thrives like the leaves on a tree" Hubert Lee, head of the Mercedes-Benz advanced design studios said.

The Ships that Fuel the World!

Oil tankers are supposed to be one of the gigantic-sized types of water vehicles. They may be 350 mts high on average which is higher than Statue of Liberty and Eiffel tower. Without their mammoth size, today's petroleum-guzzling world would come to an abrupt halt!
Today's industrialized world is daily dependent on thousands of tons of crude oil, which in turn is converted into the petrol and petrochemicals sustaining our transport systems, businesses and homes. It's the enormous bulk oil tankers that carry this precious commodity around the world from well-head to processing plant. Today, the world's demand for oil is as insatiable as ever. There are more than 3700 tankers in operation and they include the world's largest ships. Oil tankers carry around 2,000,000,000 metric tons of oil each year, making them a very important subject in transportation geography. When compared to other methods of moving oil, oil tankers are considered the most efficient method aside from pipelines because of the amount of oil they can move at any given time. Due to their size, it costs an average of only two to four cents per gallon to move oil with an oil tanker.
Oil is moved onto an oil tanker in one of several ways .Oil is pumped into the tanks on the oil tanker. As the oil enters these tanks, it emits vapors that are either released into the atmosphere or captured and discharged back into the pump via vapor recovery lines. The loading of oil onto an oil tanker usually begins at low pressure to ensure there are no leaks or other equipment problems. Once the tanks are almost full, the pressure is increased until loading and "topping off" occurs. During the topping off phase, crew members monitor how much space is left in the tanks and begin to close all valves and complete the flow of oil onto the tanker.
Despite their efficiency in moving oil to destinations around the world, oil tankers are often criticized because of the possibility pollution, accidents and oil spills.

Facts about nuclear power

The unfolding nuclear crisis in Japan has called attention to nuclear-power production in the world. Though the United States has more reactors than any other country by several dozen, no single site (besides one) is especially big. The global march toward nuclear power can't be stopped. There are approximately 440 nuclear reactors in operation around the world. There are another 62 under construction. Another 158 have made it through the planning stages and are waiting to be built. And, finally, another 324 reactors have been proposed. That's over 540 reactors that planners intend to have up and running by 2030. China intends to have almost 200 by then, making up about one-fifth of the world's nuclear reactors.
As the world waits to see if Japan can avoid nuclear catastrophe, some facts men should know about nuclear power are listed below.

1.The first thing men should know about nuclear power is that Fukushima Daiichi will most likely not impact the global march toward nuclear power. This is one steam train that can't be stopped.

2- Nuclear power is only one-third efficient
More precisely, nuclear reactors operate at around 33% efficiency, losing twice that amount in heat waste, which is carried away by coolant water. Nuclear power is a modern spin on an old idea: the steam engine. Burn a fuel in an enclosed space and allow the steam to force the movement of pistons, which creates energy. Instead of shoveling coal into a fire to produce steam, nuclear reactors use fission to split enriched uranium atoms in a self-sustaining chain reaction that heats the rods containing the fuel to high temperatures, which turn the water surrounding them into the steam that forces the pistons. Maintaining a constant temperature using coolant water is therefore of utmost importance. Without it, the fuel rods get hotter and hotter, until they make true that awful word -- meltdown.

3- Nuclear power plants are designed to shut down in an earthquake
Another thing men should know about nuclear power is that the reactors are built with multiple safety features to account for any imaginable disaster. And that sometimes this isn't enough. Seismic detectors shut down Fukushima's reactors following the massive offshore earthquake, causing control rods into the reactor to control the fission reaction. But the second part of this safety measure -- circulating water to cool down the fuel rods -- failed to happen because of an ironic mishap -- a power outage. So another safety feature, a diesel generator, kicked in to cool the rods. Then the tsunami hit, which, in the devastation it wreaked, caused the generator to die. A third safety system, which converts steam to water to cool the rods, failed as well because the water level inside the reactor was too low.

4- Coal mining kills more annually than any nuclear catastrophe has

Fossil fuel remains the largest provider of energy in the U.S. U.S. coal miners are six times more likely to die at work than are workers in any other industry, making it one of the deadliest jobs in the country.

5- The fuel for nuclear power is both abundant and unreachable

The last thing men should know about nuclear power is that its source fuel is astonishingly abundant -- and currently beyond our reach. The amount of uranium that can be mined is believed to be enough to last about a century. That ought to give scientists enough time to figure out how to tap the most abundant source of uranium on the planet -- the ocean. Most estimates put the amount of available uranium there at around 4.5 billion tons, or 1,000 times as much as can be found in uranium mines.
