Around the World With Solar Power

Expeditions around the world with ships already made history when Ferdinand Magellan did it for the first time in 1519-1522, using sailing ships. Now MS Tûranor PlanetSolar made new history as the first solar-fueled ships around the world. 
After an amazing 18-month journey, the Tûranor PlanetSolar sun-powered boat completes its around-the-world trip today! The world's largest solar-powered boat originally launched on its worldwide trip from Monaco in September 2010 and today (May 4th) the boat will officially finish the trip. The Swiss-designed solar boat is powered by 537 square meters of photovoltaic panels that enabled it to travel around the world and hit spots like Miami, Cancún, Brisbane, Singapore, Hong Kong and Abu Dhabi.

Ship with a length of 31 meters and 15 meters wide, letter T-shaped is a phenomenal journey within 19 months. This clean and quiet vessel has been launched in March 2010 in Kiel, Germany, in the shipyards of Knierim Yachtbau after 14 months of construction. 

Shipping starts from Monaco on 27 September 2010 and ended on May 4, 2012. During the trip, Tûranor stopped in six continents. Ships also stop in Cancun, Mexico, when the United Nations held World Climate Conference in November 2010.
After crossing the Atlantic ocean, the Panama Canal, the Pacific ocean, the Indian ocean, the Suez Canal, and the Mediterranean, the Tûranor completes its trip today (May 4th) by arriving at Hercule Harbor in Monaco. (Picture from: http://inhabitat.com/)
"When the ship rests, I will miss the times when sailing," said Raphael Domjan, the expedition leader as well as designer of the ship. 

Tûranor name means strength of the sun, taken from the phenomenal novel The Lord of the Rings by J.R.R. Tolkien. This name shows how the ship and six crew could sail by just relying on solar energy.

Tûranor made flat deck and into the installation of solar panel covering 537 square meters. Panels made from silicon is able to convert 18.8 percent of sunlight into electrical energy which is stored into the six-power lithium-ion battery is 93.5 kilowatts. With that much power, the ship is able to divide the sea with peak speeds of 15 knots, equivalent to 27.3 kilometers per hour. 

The expedition which cost U.S. $ 24 million, was carried out to campaign for clean energy to the world. Sunlight is a clean energy source and free to be learned in all the world, including the oceans. 
When it sailed 500 years ago, the solar panel technology has not been known by Magellan that they rely on cheap and free energy, like wind. "We hope that the expedition was to motivate the development of innovative technologies," said Domjan. *** [PLANETSOLAR | SCIENTIFICAMERICAN | ANTON WILLIAM | KORAN TEMPO 3874]Enhanced by Zemanta

Moon Was The Main Cause of the Titanic Sinking

Anyone who knows history or has seen the blockbuster movies knows that the cause of the transatlantic liner's accident 100 years ago in April was that it hit an iceberg. But now, a century later, scientists found that the main factor causing the trans-Atlantic ship sank, the moon.

"The moon and its influence can explain how a very large iceberg can enter the Titanic cruise lines," said Donald Olson, a physicist at Texas State University, USA. Olson led a team of forensic astronomers to investigate the role of the moon. 

Titanic sank at dawn on 15 April 1912 and 1.517 passengers and crew killed. Since then, researchers continue to be puzzled by the attitude of Captain Edward Smith doubt that there are warnings that an iceberg in the path of the Titanic sailed. 

Olson said Smith is known as the most experienced captain in the White Star Line and was sailing in the North Atlantic sea lanes in a variety of occasions. "So, how can a mountain of ice chunks float away to the south to enter the shipping lanes in the south of Newfoundland night?" Olson said. 

The research team investigating allegations that oceanographers Fergus Wood said distance of the moon to Earth in January 1912 extraordinary close. As a result, a high tide occurs that triggers the iceberg broke away from Greenland. Giant iceberg that floats and moves into the shipping lanes, which in the previous autumn had been moved to the south because of the reports of the presence of icebergs in the usual channels. 

Olson said the natural phenomena on January 4, 1912 is a very rare occurrence. When the moon and sun line up in such a way as to enhance mutual gravitational force. "The configuration of all of this to maximize the role of the moon as the cause of the tides," said Olson. 
THE MOON'S FAULT?: A "once-in-many-lifetimes" event involving the moon may have been responsible for the Titanic's sinking, scientists say. (Picture from: http://www.stuff.co.nz/)
Olson and his team of research will be published in Sky & Telescope magazine in April, exactly a century the tragedy of the Titanic sinking. *** [REUTERS | MAHARDIKA SATRIA HADI | KORAN TEMPO 3817]

The Moving Tropical Island Concept

Little more than a decade after starting the business, Monaco-based company Wally Yachts continues to develop innovative concepts and minimalist luxury at a rate exceeding any other marine design house on the planet. the newest innovation was WallyIsland - a 99 meters (325 feet) "gigayacht" that dwarfs among the most luxurious megayachts and reconceives yacht as a floating private island, a mobile address can be used as a home, entertaining space or even a moving exhibition or performance space.

WallyIsland not the first of a new generation of luxury gigayachts - nor is it the largest. Paul Allen's Octopus, for example, is a 410-foot giant built by Lürssen, and the Sheikh of Dubai.currently owns the world's largest luxury motoryacht at a staggering 525 feet long. A 405-footer by Frank Mulder was even auctioned off recently on eBay. Nevertheless WallyIsland has some unique features.

WallyIsland more like a tankers than its gigayacht brethren, because the area of ​​1,000 m2 on the main deck and the fact that is has only three upper-level decks rather than the multilevel arrangements typical on others. It is designed this way to add an open entertaining space and allowing a large garden space, and this sort of design also makes the cost of the yacht "competitive," though we would shudder to imagine what "competitive" means in this kind of business. Wally claims it's roughly in line with what you'd pay for a traditional design 200-footer.

WallyIsland main deck can include a large swimming pool and in the room, gardens, tennis or mini soccer field and a helicopter pad required. This includes the bed up to 40 crew and 24 guests as well as the extravagant owner's suite. It holds about three-quarters of a million liters of fuel, and the rear deck holds two 45-foot yacht tender WallyPower, as well as space for several other yachts and watertoys on board.

Interior features of the main saloon, living / dining room, guest accommodation, library, cinema, spa, wellness and fitness, the service and the crew, and the steering/navigation area.

At U.S. $ 200 million (or approx Rp. 1.92 billion), Wally Island is not for common people, but the concept seems to have triggered the bustle in the marine industry, with new designs all the more focused on living comfortably move framed as a boat floating over the island.

It seems that now the naval architectural mold is broken, and has moved beyond the traditional areas, the new purpose-built, holistic design has begun to emerge, especially the works of Wally Yachts, Dutch Docklands Maldives and Italian industrial designer Michele Puzzolante and others. There are many more ideas and concepts that can be developed from this technology now. *** [GIZMAG | WALLY | EKA | FROM VARIOUS SOURCES]

Dive Into Life Submariners

The submarine is one of the results were amazing technology. When the Afghan war broke out, some of the Tomahawk missiles fired from American and British submarines. Its role in winning the war is quite large. For the crew, the battle is not just happening on the surface of water, but also under the sea. Real battle going on inside the submarine itself. They had to fight with boredom, fear, and isolation. A crew of submarine warfare can live for months, even years, under the sea. Space is very limited. A fighter submarine has a length of 85.5 meters by 9.5 meters wide and 9.5 meters high. Daily Mail journalist, Danny Danzinger, recently tried to ride the Royal Navy's submarine the British navy for three weeks. He wanted to know more closely the life inside the submarine. In his report, Danzinger admitted, while in the submarine, life is slow and monotonous. Meals per week have never changed. People and environments encountered always the same from day to day. "They do a very dangerous and should have high discipline in conditions that are totally uncomfortable. But they are not awarded anything," Danzinger said. Living in a submarine is far from pleasant. There was no sunlight or fresh air intake. Living alone, surrounded by walls of iron and steel. No windows or exits. So, how do they get the air supply? There are three main problems is crucial for a submarine which is always a top priority, namely to maintain air quality, maintain a supply of fresh air, as well as maintaining the room temperature. Maintaining air quality is not easy. Therefore, the inhaled air contains four elements, nitrogen (78 percent), oxygen (21 percent), argon (0.94 percent), and carbon dioxide (0.04 percent). When breathing air, the body takes the oxygen and convert it into carbon dioxide when released. Incurred while breathing air that contains 4.5 percent carbon dioxide. The body of nitrogen and argon can not change it. In order for the air quality is always maintained in a submarine, three things must be considered is the oxygen levels should always be in sufficient quantities to be inhaled. If the percentage of oxygen levels drop, the crew will experience shortness of breath and died. Carbon dioxide must be immediately removed from the room. If there's too much, gas is very dangerous because it will turn into toxic and deadly. Finally, water vapor that comes out during breathing must also be eliminated. Oxygen can be obtained from high-pressure air tank or oxygen generator (obtained by the method of water electrolysis, which separates the elements hydrogen and oxygen from H2O), or the method of "oxygen canister", which release oxygen to the heat of chemical reactions. Carbon dioxide can be removed from air by chemical processes, namely by using soda lime (sodium hydroxide and calcium hydroxide) in a tool called scrubbers. Carbon dioxide is captured from the air by the lime soda through chemical reactions and purged of air. While the humidity can be eliminated by using a neutralizing moisture or by chemical processes. The purpose of moisture reduction to prevent rust on the vessel wall or other critical equipment. In addition to other gases, like carbon monoxide or hydrogen, caused by a ship's machinery or cigarette smoke, can be removed by burning. While the dust and par Another small tikel removed by using air filters. So, what about water? To get clean water not as complicated to control air quality. Almost all of the submarine is equipped with water purification devices, which convert the salty sea water into fresh water. Water purifying machine will heat the sea water to evaporate. The goal is to remove salt from water. Furthermore, the purified water was cooled and stored in a tank of clean water. A water purifying machines capable of producing 38-150 thousand liters of water per day. Freshwater is used to cool electronic equipment, such as computers and navigation equipment. Moreover, for everyday needs, such as cooking, drinking, and bathing. One thing that is not less important is to keep the air temperature remains comfortable. Because the submarine is always under the surface of the water, the air temperature inside the cabin can reach 4 degrees Celsius. Typically, to warm the room, use the heater. While the electric power derived from nuclear reactors (if it is a nuclear-powered submarine), diesel engine, or batteries. Although the facility is complete, Danzinger claims have absolutely no interest to submariners. *** [MAILONLINE | HOWITWORKS | FIRMAN | KORAN TEMPO 3615]
