Using Kites to Pull Cargo Ships Across the Seas
A few months ago we reported on future attempts to use a kite to move a cargo ship across the ocean. But just last week, the MS Beluga set sail on its maiden voyage from Bremerhaven to Venezuela where it showed, quite successfully, that wind power might just be the future of nautical transportation.
The MS Beluga is a 140 meter long cargo ship. It uses a 160 square meter sky-sail which is set to fly at a height between 100 and 300 meters above the ocean. While it is not the main mode of propulsion, the kite is able to reduce fuel consumption by about 10% to 35% depending on wind conditions. The Skysail is the creation of Stephan Wrage who believes these kites could be used on almost 60% of all cargo ships. It is attached to the ship by a single line that is controlled by a computer, and works precisely as you’d expect, like a giant version of a small kite.
The maiden voyage started just last week, and already the sail has been deployed. It will cross the Atlantic Ocean using the traditional windjammer route south of the Azores. Its full travelling time is expected to be a total of 15 days. If successful, the company expects to deploy this system on other cargo ships.
RECLAIMING DESIGN
A few weeks ago, Inhabitat put together an event about recycling and reuse in design, called Reclaiming Design. This event at HauteGREEN in New York was a big success, thanks to the thought-provoking design and insightful discussion from Dwell Editor-in-Chief Sam Grawe and designers Carlos Salgado of Scrapile, Tejo Remy of Droog fame, and Matt Gagnon.
Our conversation touched on a variety of issues surrounding the concepts and processes behind using reclaimed materials in different scales of design, and its implications for both environmental sustainability as well as more conceptual and cultural themes.
The event was organized in order to explore what it means to recycle, reduce and reuse within the context of design. Our four panelists manage to not only touch on these issues, but raise many others that provided some great green design conceptual fodder for further discussion.After each of our panelists showed their own work and weighed in Reclaiming Design, Jill and I began a moderated question and answer session that raised some interesting topics of discussion. We talked about the historical influences, how reclaiming older materials relates to DIY (do-it-yourself) projects, and the design market for such products and architecture that integrate recycled materials. Jill discussed the idea of the changing social acceptance of “recycling” and its interpretation within differing cultural connotations, while Sam Grawe weighed in on the architectural possibilities of recycling and reclaiming materials.
The question-and-answer session was chock-full of thought-provoking and sometimes contrasting ideas, but each of the panelists seemed to agree on the same things – sustainable design (and particularly the use of reclaimed materials) is an ongoing and complicated process that manifests itself in different ways. There is no “perfect green design;” in fact, as Jill remarked, designing “green” is actually a series of unique solutions to individual problems that attempt to balance health, environmental, social, and aesthetic issues as best as possible.We want to thank HauteGREEN for helping the event come together so successfully, and all of you who showed up to perch on the upside-down buckets to hear the conversation. Hope to see you again next year!
PEV – Personal Electric Vehicle
With a name like ‘No More Gas’, you can bet that this cute little personal electric vehicle is as good to the environment as it is to the user. Its size, weight and fuel make it much better for the planet, while its look and driving experience make it great fun for the driver. Looking like it’s dropped straight out of an episode of The Jetsons, this tiny car can achieve speeds of over 75mph for a cost of $0.02 per mile. All this eco-goodness earned Myers Motors’ NmG vehicle kudos at this year’s Well-Tech Awards exhibit in Milan.
Much of the NmG’s benefits stem from its size. Holding just one person, it’s much smaller than the average car. Smaller cars means more commuters can fit on the roads, getting where they need to be in a shorter time. The size also enables drastic reductions in fuel consumption, earning it the title of the most energy efficient vehicle on the road today. Its size also allows the NmG to achieve a range of 25 to 30 miles, making it suitable for the vast majority of commutes.
Plug the vehicle into a 220 volt socket to fully recharge an empty battery in 3 hours. Fuel costs are around a quarter of the price of conventional oil-powered transportation. Charged using conventional electricity, NmG’s size and power type reduces emissions by around 70% compared to a conventional fossil fuel-powered car. And, of course, emissions are eliminated completely when the car is charged using a home-based renewable energy system.
The design sits halfway between a car and a motorbike so the manufacturers prefer to call it a ‘Personal Electric Vehicle’, or PEV. And because the US Department of Transportation classifies the NmG as a motorcycle, it’s permitted to go on highways traveling to speeds around 75mph while other electric vehicles are legally limited to speeds of 35mph or less. A speedier drive is also likely because the NmG is allowed in many carpool lanes, due to being ‘fully occupied’ by the driver alone.
The retro-futuristic vehicle is available in many bright colors for the reasonable price of $36,000. So, all in all, its an affordable, cheery, environmentally-friendly car that’s supported by existing infrastructures. We’re looking forward to spotting many more NmGs on the roads very soon.
Cardboard bike aims to put brakes on thieves
A bicycle is stolen in England every 71 seconds. So how do you solve this problem through the power of design? According to design student Phil Bridge, make a bike so cheap that there’s no incentive to steal it. And the intrepid design student did just that, by building a bike for about $30 made out of cardboard. Yes, my friends, cardboard!
The 21 year old student designed and created a cardboard bike as part of his degree course in product design at Sheffield Hallam University. The bicycle is not made out of simple ordinary corrugated cardboard, as that would not be strong enough to hold a person’s weight. Instead, Phil used hexacomb board, a more structurally stable form of cardboard which, by the way, is also waterproof. Not all of the bike is made out of cardboard. Tires, chain and brakes are still the same metal and rubber components as any other bike.
The cheap and cheerful cardboard bicycle will hold anyone, provided such person does not weigh more than 168 pounds. And while not designed for speed, the bike does work and will get you to where you want to go. Bridge is now hoping to get a sponsor for to turn his bike into an actual product. Any takers?
OILgae test drive – Algae power hits the road
Corn and soybean derived biofuels have long been the most promising options on the table for escaping the clutches of fast depleting petroleum. However, acquiring the space necessary to produce ethanol and biodiesel at the same consumption rate as fossil fuels would be impossible, so sustainable fingers are pointing to oilgae, or algae fuel. Algae produces 30 times more energy per acre than corn or soybeans and can grow in salt water, our worlds most abundant source. There are several startups bringing pond scum to fuel tanks, among them Solazyme who were caught driving around Sundance Film Festival this year with an oilgae-powered car.
US Biotech firm Solazyme unveiled an algae-fueled Mercedes C320 at the Sundance Film Festival in January marking the first real-world road test of biodiesel made from algae. Solazyme president and CTO Harrison Dillon said the Sundance test drive responds to “the need for a near-term solution that will also be cost effective and sustainable. Our technology combines all the key components: low carbon footprint, environmental sustainability, certified compatibility with existing vehicles and infrastructure, and energy security for our country,” in a press release. The company has since coupled with the Chevron Corporation and plan on producing algae-derived fuels for consumer use in the next three years.
Solazyme grows algae in fermentation tanks without sunlight, by feeding it sugar. Algae suitable for biofuels can be grown in open ponds or lakes or enclosed in heated greenhouse structures to promote year-long growth. And since the production of algae doesn’t hinder food and livestock feed production like corn and soybeans, its effect on the ecosystem and the food chain is significantly reduced.
But what’s a great idea without a catch? In open systems like natural ponds and lakes algae is susceptible to bacteria and contamination, and at the whim of the water and air temperature and access to light. In closed systems, algae grows in contained ponds or pools eliminating much of the risk of environmental variables, though requires more attention, equipment, and space. One of the commercial readiness hurdles is managing production at a feasible market price. Algae biofuels are still being researched and tested throughout the world and will someday (hopefully soon) offer us a cleaner way to get around.
