Innovative technology for modern sea transportation

SkySails GmbH & Co. KG, based in Hamburg, Germany (www.skysails.com), develops, produces, and distributes towing kite wind propulsion systems for modern means of sea travel and transportation. These systems make the operation of ships more profitable, safe, environment friendly, and independent of scarce oil resources. The SkySails system consists of a large towing kite similar to a paraglider, which is navigated by a fully- automated control pod and is connected to the ship via a towing rope. The towing kite, an airfoil similar to that of a paraglider, or parafoil for short, generates propelling forces. The control pod performs similar tasks as a paraglider pilot - shortens or lengthens the control cords, thus changing the aerodynamic profile of the towing kite - and governs its flight path. The Control System controls the SkySail system, comparable to an aircraft’s auto pilot. The traction forces are transmitted to the ship via a traction cord made of modern synthetic fibers, ensuring high load capacity as well as low weight and low elongation under load. An automated routeing system, aligned with historic routes of large cargo sailers, will allow cargo ships to reach their destination as quickly, and at a much cheaper cost. Maple’s role in the simulation software SkySails used Maple to develop its simulation software. Maple was chosen for its symbolic computation engine, which considerably simplifies the derivation of the equations of motion for multi body systems. Editing the three-dimensional mathematical models by hand was not feasible within the company’s time frame. Many matrix operations and derivatives needed to be applied in order to set up the equations in three dimensions. SkySails said : “SkySails is grateful to Maplesoft, because Maple saved us a lot of time. Using Maple was very easy and quick. The computations we used are probably very basic for Maple, but they were extremely effective for SkySails. When testing the simulator, the correctness of the mathematical model is crucial. With Maple, there was nothing to worry about!” A flight simulator presenting the movements of the kite system in real time is under development. Updated: February 2008 First cargo ship run on wind power begins journey SkySails’ first cargo ship, with a huge computer-controlled kite, was flagged off in December 2007 by Eva Luise Koehler, wife of German President Horst Koehler. The ship MV "Beluga SkySails" started its maiden voyage from the city of Bremerhaven, Germany to South & North America (and back) and the SkySails-System with its 1,722 square-foot towing kite has been put into operation successfully. This new technology can tow cargo vessels and superyachts, reducing fuel consumption by 10 to 35% on annual average . SkySails used Maple symbolic mathematical software for engineers to develop its simulation devices.

Eco-friendly super yacht by Dennis Ingemansson

While many environmentalists feel that mega-mansions, yachts and other trappings of the uber-wealthy just can’t be green no matter what, others don’t think the public should be asked to give up luxury to save the planet. But where is the line drawn?
A new “eco-friendly superyacht” raises this debate anew. Sylvain Viau’s 80m OrganiK is a yacht of absolutely ridiculous proportions, including a private apartment, guest gym, large salon, dining room, galley, second salon/library, four guest cabins and more.

So what makes it (supposedly) green? Other than its sleek aerodynamic shape and the fact that it runs on hydrogen fuel cells, details aren’t too clear. Super Yacht Times says,

Many of the on-board services, such as the hot water production and air-conditioning, are based on Ecological-friendly systems. Here again significant savings are expected by the designers, enhancing the green idea behind the concept.
The superyacht’s composite mast will hide all antennas and domes, keeping the overall design of the superyacht clean. The entire concept has been designed towards minimum carbon footprint, in both construction and use of the vessel.

At this point, it’s tough to tell whether this yacht has any real eco-cred or it’s all just lip service. But if it’s the real deal, it’s a step forward, even if a frivolous one. Being green doesn’t mean giving up all the fun things in life – just finding better, more planet-friendly ways to enjoy them – but there is a definite difference between harmless fun and selfish showboating.

Uniqu Eco looks on the flip side

Top shop; Accessorize; Muse, everyone has heard of these high street shops, right? What about Flip Flop? Never heard of it? Well I think it’s about time you do. If you want custom made handbags; bracelets; necklaces that are all made from recycle flip flops, yes flip flops, then you found it in UniquEco.

Flip flops washed up and reused

UniquEco is a foundation set up from East Africa; the project was founded by the woman of Kiwayu, which is a small island in Northern Kenyan Coastline. Not only does this project help the environment it gives the women of Kiwayu, who live in Africa a source of power. In the remote areas of Africa there are very few ways to earn a living; now woman’s roles in the community have grown; they are now economic decision markers paying for households; food and education for the families.

Why flip flops then, why not plastic or snack wrappers? Well flip flops are washed up on East African Beaches. Waste is a problem all around the world but in East Africa it was becoming a real big problem and the locals needed to do something with the sudden growth of rubbish on their beaches.

So what does this organisation do then? UniquEco collects the flip flops; recycles and cleans everything they find; create their wonderful work; sells all the products to tourist and local residents in all the shops and craft fairs; amazingly 80% of their goods are exported all over the world; the sales generated are put into buying more flip flops and getting 150 people employed; it rises education in Africa, by recycling all rubbish and flip flops that end up on the beaches. UniquEco are spreading the word about recycling and making everyone think we should do something about it.

So from all this do you still think high Street is the best? With companies like UniquEco around that are helping the environment and have such good intentions behind them not just to making you look good. Then is it really a good plan to splash your hard earned money on a £25 bracelet that might only last a few weeks in the cutting edge of fashion or your money on something that will look good all year round and that is made with love and attention.

Areca Nuts | the Chew of Maldives

A slice of Areca nut

Areca nuts, often erroneously referred as the betel nuts are widely used as a mint after meals and holds a distinct history in Maldives.

According to historians and travelers like François Pyrard de Laval, areca nuts were deeply embedded into the Maldivian culture. The early Maldivians used a girdle on their waist in which they kept a good supply of areca nuts and it was customary that when they meet each other on the road, may it be a friend or stranger to offer his own betel nuts. It was also bestowed as a royal gift and offered to the person who proposes for marriage as a gift of approval.

Such traditions have changed over time but the areca nut continues to dominate the ‘chewing culture’ in the Maldives. It is now offered in almost all cafés, restaurants and shops in Maldives, in different forms with fixings like betel leaf, cloves and lime. Some modern innovations of the areca nut includes the ‘Kill’ a finely ground mixture of areca nuts, betel leaves, cardamon, sugar and cloves. Another form is ‘Supari’ a sweet flavored betel nut chunks in small sachets imported from India.

maldivian arts | bodu beru

Bodu Beru meaning ‘Big Drum’ which usually takes place during special occasions is one of the most popular forms of traditional folk music in the Maldives and is enjoyed by all ages.

A bodu beru group consists of a lead singer along with a group of up to 15 people singing in chorus. The drums are traditionally made from hollowed coconut wood, goatskin enclosure on each side and are mostly beaten with bare hands. The most interesting point of Bodu Beru is its blood-pumping ascending tempo along with the lyrics that have no definite meaning. At present times meaningful songs in Dhivehi language is also used. Bodu Beru dates back to as early as the twelfth century, even before the Maldivians converted to Islam. “Baburu lava”, a form of bodu beru chant hints that this tradition may have been originated in East Africa and had been passed through generations by our forefathers, as is our responsibility to pass this artistic Maldivian tradition to the future generations.

Nuts for Coconuts | Toddy - The Local Brew

Toddy is the sap of the coconut palm extracted from the flower buds by toddy tappers. Toddy tapping or ‘raa verikan’ goes a long way into the Maldivian history and it used to be a remarkable occupation passed from father to son.

Toddy tappers cut the end of the inflorescence when it is ready to ripen and hangs a collecting pot specially made from coconut shells called ‘Gudi’ and is left to fill overnight. The toddy is then collected following day and transferred into a coconut container called ‘Raa badhi.’ Sweetness differs according to the time of collection with the evening toddy being the sweetest. The collected toddy is then sold by the glass in the fresh form, a tasty sweet drink despite its pungent odor.

Maldivians use toddy in different ways. It is heated to make ‘Dhiyaa Hakuru’ a golden honey-like-liquid similar to Maple Syrup which Maldivians enjoy eating with rice, coconut crepes and also acts as a main ingredient in sweet cakes, desserts and snacks. This syrup is further cooked under low-heat with a pinch of sugar and a particular form of coral for an extended period which then turns into a creamy-white paste called “Karu Hakuru.” This is used as a breadfruit chips dip or spread on thin coconut bread.

In the olden days, these syrups were a staple in the households and were also relished by sailors and fishermen as their diet onboard for distant journeys as these toddy products lasted several months without refrigeration or preservatives.

Toddy is also fermented and turned to toddy vinegar which has a strong acidic flavor with a hint of coconut taste. This vinegar is used in flavoring other food products and as a preservative to make local pickles or ‘assara’.

Today, Toddy and toddy products are very rare but it is still available infrequently throughout the Maldivian Islands. With modernization, the art of toddy tapping is almost lost. The government has recently stepped in and has introduced ‘toddy tapping’ courses in the atolls in order to revive this fading Maldivian tradition.

If you happen to tour Malé, the capital island, stop by the local market to find these 'Dhiyaa Hakuru' and 'Karu Hakuru' among other local food products.

In order to create an eco-conscious generation for a greener future, we need to educate and create environmental awareness among children from a young age.

There are plenty of eco-educational activities and games for children to have fun while learning such as making art & crafts using recycled materials, beach games or even snorkeling. Drop a few Eco tips along the way as you go on with your daily lives. Shopping can be turned into an interesting search for eco friendly labels and products, also the best time to provide awareness about animal products such as turtle shells, leather and fur.

If you are setting out for a vacation, look for eco-friendly resorts offering such activities for children. The Four Seasons Resorts Maldives at Landaa Giraavaru lets the children snorkel and explore nemo’s home with a marine biologist, making it fun to learn about marine life while the Shangri-La Vilingili Resort & Spa offers nature trails to discover the island's indigenous flora and fauna. Conrad Maldives Rangali Island also offers the opportunity of spotting colorful fish on a snorkeling trip or going exploring for dolphins.
