On Sept. 5,  SpaceShipTwo achieved supersonic flight hitting mach 1.43 during its climb from its release point at 42,000 feet to 69,000 feet (21 km) over the Mojave Desert. In addition to achieving the highest altitude and greatest speed to date, the test flight demonstrated the vehicle's full technical mission profile in a single flight for the first time ... All of the test objectives were successfully completed.

 Nanotechnology to produce thin films with special quantum effects.

In traditional semiconductor cells, such as polycrystalline silicon solar cells a single photon can only excite a single exciton.  Typically photons from our sun have more than twice the amount of energy needed to excite one electron, so in these materials after excitation this extra energy is lost.  Thus the maximum theoretical efficiency of traditional thin film cells is around 45 percent.

Nanotechnology can be used to produce thin films with special quantum effects. One major research push is to work on the exciton generation, in so-called "excitonic solar cells" such as quantum-dot based dye-sentized solar cells (DSSCs) and other new/exotic material cells.  The goal here is  to find materials that create multiple excitons from a single photon, a phenomena known as MEG (multiple-exciton generation).  The LLNL  work (study) made layers of ordered nanopillars about 50 nanometers in width and between 250 and 1400 nanometers (1.4 µm) in height.  Nanowire thin films of gold, aluminum, and silver were tested. The study indicated that taller nanowires perform the best.  And surprisingly the aluminum -- while more reflective (88% avg. reflection) than gold (74%) in unpatterned flat films -- performs the best in black metal films, covering the broadest array of spectrum including the entire visible range.

World's Biggest Ship in 2013 - The Triple E Class

The world’s largest container vessel – the Triple-E class - with a capacity of 18,000 twenty-foot containers (TEU) is being built at Koreas Daewoo Shipbuilding and Marine Engineering Co. Ltd. for A.P. MOLLER - MAERSK.

The ship is four-hundred metres long, 59 metres wide and 73 metres high. The shipping line ordered  20 new vessels and they will be deployed on the  Asia to Europe trade.

The Triple-E refers to the three main purposes behind the creation — Economy of scale, Energy efficiency and Environmental efficiency.

The Triple-E at a glance:

The Triple-E will emit 20% less CO2 per container moved compared to the Emma Maersk, currently the world’s largest container vessel, and 50% less than the industry average on the Asia-Europe trade lane.

The vessels will be equipped with a waste heat recovery system, saving up to 10% of main engine power. This equals the average annual electricity consumption of 5,000 European households.

Triple-E vessels travel 184 kilometres using 1 kWh of energy per ton of cargo, whereas a jumbo jet travels half a kilometre using the same amount of energy per ton of cargo.

Since this is a container ship the easiest way to look at performance is by individual container cost. The fuel consumed per container will be about one third as much as the average ship working currently on Asia - Europe routes.

The first 10 vessels will be delivered during 2013 - 2014, with the remaining scheduled for delivery in 2015.

The first ship was delivered and was named 'Maersk Mc-Kinney Moller'

How the economy and efficiency are being achieved

When a ship is built larger the interior volume obviously increases but the portion of the hull exposed to the most friction grows much less.

The friction that causes drag in the water is mostly confined to the bow and stern transitions. Increasing length contributes little to the overall drag of a hull.

Hull shape is also a major contributor to the design. The Maersk Triple-E uses a bulbous bow like most modern ships. This protruding bow below the waterline produces a lower pressure cone of water that allows the ship to slide trough the water with much less resistance.

Maiden Voyage Event Shanghai

The Maersk Mc-Kinney Møller left on its maiden voyage from Busan on July 15, calling at Shanghai’s Yanshan Port, the largest in the world, then proceeding south to Ningbo, Yantian, Hong Kong, Singapore, and Malaysia’s Tanjung Pelepas. On Aug. 9 it passed through the Suez Canal, and a week later it arrived in Rotterdam

Each of the ship’s 31 pre-fabricated mega-sections were lifted by a giant scissor lift crane then dropped into the dry dock and neatly aligned to within four millimeters of the adjacent block.

A difference in point of view about a facility - Value Engineering Implication

A dispute over what sort of glass to install along the bridge wings dragged on for two weeks. Unlike on most container ships, where the walkways on either side of the pilothouse are open to the elements, the Triple-E’s were to be enclosed. Pointing out that international standards required a “clear view” from the bridge, Maersk insisted that the glass in those wing windows be heated, with windshield wipers, as it was for the pilothouse. But DSME argued that heated glass and wipers, while clearly required for the pilothouse, were unnecessary on the bridge wings, and that “clear view” simply meant “window.” At stake was $100,000 in costs.

The companies appealed to the American Bureau of Shipping, an international classification society, which was unable to resolve the dispute. Eventually they reached a compromise: a mix of heated and unheated panes on each bridge wing; some with wipers.


Freight Costs Information

A year ago, according to the British shipping consultancy Drewry, it cost $2,900 to ship a container from Hong Kong to Los Angeles. Since then rates have dropped by a third (Sep 2013)

May 16 2013
A rate war has erupted in the Asia-Europe rote, which has forced rates down below the US$1,000 per TEU (twenty-foot equivalent unit) level, as operators fight for market share.
Ships are now sailing at a loss – a container can be shipped between Shanghai and Rotterdam for just US$740.

 A 100,000-horsepower engine such as the one in Maersk’s 15,500-TEU E-class—until now the biggest ships in the world—burns 33,000 gallons a day. Fuel costs for a one-way trip from Rotterdam to Shanghai can easily reach $2.5 million.

The Triple-E’s capacity is 18,000 TEU. Practically speaking, a Triple-E, in one trip, could take more than 182 million iPads or 111 million pairs of shoes from Shanghai to Rotterdam. Such a trip would take 25 days and burn 530,000 gallons of fuel. That comes to 0.003 gallons per iPad. If one take $1000 per container as freight, in one full loaded trip, the ship will $18 million. The fuel cost will be $4.2 million. Each container will carry 10,000 ipads and that means per ipad the tranportation cost will be $0.1.
