Solar Impulse, Around The World In A Solar Airplane

solar_impulse.jpg

Based in Switzerland, a team of over 50 specialists from six countries is working on the Solar Impulse project: a solar-powered airplane capable of taking off autonomously and maintaining itself in flight for several days, entirely propelled by the energy stored in the photovoltaic panels contained in its wings.

The HB-SIA prototype is currently under construction and the round-the-world flight is programmed to happen in 2012, on a flight over land near the equator. Five stops are planned during the route, in order to change pilots and present the adventure to the public and authorities. Each flight leg will last from 3 to 4 days (considered the maximum endurance for a single pilot).

This is certainly a technology many of us have been waiting for, and which seems a natural step in the aviation industry.

Building with Bamboo

bamboo-bridge.gif

Thanks to the efforts of Yan Xiao, an engineering professor at the University of Southern California, bamboo can now be turned into structural beams to build and support houses and even bridges. Initially reserved for cosmetic and non-load bearing applications, bamboo is now a viable alternative to traditional hard wood lumber. Xiao’s invention, called GluBam, is a structural lumber made from laminated bamboo veneers that are pressed into beams. The beams can be cut and handled like traditional lumber, but come from a rapidly renewable resource.

Yan Xiao’s GluBam is currently being used to construct classrooms and homes across China and was even used in a bridge in the town of Leiyang in China’s Hunan province. The bridge is the first ever to be constructed using structural bamboo and is a testament to the great strength and range of use that this new bamboo derivative has.

GluBam will also be a great aid to developing countries like China that have vast bamboo forests but lack more robust traditional hardwood resources. By transforming the bamboo stalks into manageable beams, GluBam can be used for a variety of applications and can perform just as well as its hardwood counterparts.

Bamboozled by Bamboo?

bamboo.gif

Bamboo has been touted as the new wonder fabric, it is rapidly renewable, requires little or no pesticides, and is soft to the touch. Today consumers can find many “eco-friendly” products that are made from bamboo but can it really be all that sustainable?

Bamboo is a grass that grows up to two meters per week, and is cut and not uprooted when harvested allowing it to grow back quickly. It is extremely hardy and usually requires only rainfall to grow and thus many industries find it quite appealing as a source material. Unfortunately the majority of bamboo is derived from large plantations in China that are highly under-regulated. Many of the plantations were created through the clear cutting of forests, and although usually grown organically, bamboo is very invasive and can choke out native species and greatly affect local ecosystems. To be processed into fiber, a lot of energy is also consumed and toxic chemicals like caustic soda are needed to refine it into a wearable textile. The whole production process needs greater regulation and transparency to ensure its growth and production is more sustainable.

As with most products on the market there are usually trade offs in its production and use, and bamboo is no exception. Bamboo does have some great positive attributes however; It can be made into a variety of textiles that can be as soft as cashmere or as strong and durable as denim. Bamboo is also praised for its UV protection and its anti-microbial properties although further testing is needed to bolster these claims.

There is no doubt that bamboo is a highly versatile material. It can be used successfully not just for textiles but for a variety of other industries as well. For bamboo to truly be a sustainable material however, more attention must be put on its production and how it is harvested and processed. There is no doubt that bamboo can be a great sustainable material, but the hype surrounding it can be detrimental for the real facts to come out.

Wal-Mart Unveils a New Sustainability Initiative

walmart-logo2.gif

Wal-Mart is making headlines again, thankfully this time it’s a lot less controversial. On October 22nd in Beijing, Wal-Mart held a groundbreaking conference with around 1,000 different suppliers and manufactures outlining the future goals of the company. With many companies today realizing the need for more sustainable business models, Wal-Mart is following suit with an initiative to bring more sustainable and energy efficient practices to its already immensely successful business and supply chain.

“Sustainability is about building a better business. We think it is essential to our future success as a retailer — and to meeting the expectations of customers,” said Lee Scott, president and CEO of Wal-Mart Stores, Inc. “Maintaining the trust of our customers — today and in the future — is tied hand-in-hand with improving the quality of our supplier factories and their products.”

Wal-Mart’s main initiative focuses on meeting or exceeding social and environmental standards, promoting innovation and efficiency and building stronger partnerships with suppliers, governments and NGOs. Beginning in China in 2009, Wal-Mart will create a new supplier agreement that will require factories to certify compliance with local laws and regulations as well as rigorous social and environmental standards. Wal-Mart will also partner with its top manufacturers to improve energy efficiency by 20% by 2012. Along with increasing environmental standards, Wal-Mart will also implement stricter product safety and quality measures that will greatly reduce returns of defective merchandise

Thanks to its great success, Wal-Mart is in a unique position to bring about effective change by working collaboratively with foreign suppliers and manufacturers. Although by no means the first company to strive to be more environmentally conscious, the fact that a large and powerful company like Wal-Mart is making a commitment to sustainability will no doubt have a positive impact and lead the way for other corporations to follow.

Recycled Cardboard Made Into Furniture

kroom.jpg

Krooom focuses on environmental performance and makes products which are produced with at least 60% recycled paper. Their technical team has developed and invented patented technology that has enabled the creation of products which are strong, sturdy and lightweight. They ship folded flat and require no tools for assembly. According to Nitzan Bertele, their Chief Design Officer, “advanced patented technology ensures no visible corrugated edges. Our products are completely printable, and meet many of the standards for moisture resistance.  Their production facility in China is supervised by our own staff, strictly working under international and local labor laws.”

In a typical re-manufacturing process, recycled cardboard is dropped into a water-based solution in which it dissolves, contaminants (tape, staples, dirt, etc.) are removed by gravity, flotation, or filtration, the recycled pulp is blended to produce a mix with the characteristics required for production of a specific paper product, and the pulp is pumped to a paper machine where the final product is manufactured. Paper production from recycled cardboard consumes less energy, produces fewer emissions to air and water, and generates less solid waste than production of similar products made from virgin fiber.

China Shooting for “The Green Olympics”?

image_01.gif

image_02.jpg

Just in time for the Summer Olympics, China’s capital is moving forward to improve air quality and help preserve the Earth. This year’s Olympics have been branded as the “Green Olympics” and China has been putting forth new systems, regulations, and buildings to better themselves for the future. One new rule made by the government prohibits fried food to be sold in the farmers’ market by vendors. Cooking fried foods requires the use of coal stoves, which contributes to air pollution. Although this is a great start to reduce the use of coal coming from China, vendors are still cooking with their coal stoves and selling the product but doing so before authorities arrive at 8:00 a.m.

The Beijing government has also been promoting public transportation by improving the systems, introducing incentives, and adding regulations on local vehicles. Two subway lines have been added to Beijing’s original two, and seven more are in construction. Some of these seven will be open in time for the Olympics. Tourists will find it convenient to take the metro directly from the airport to downtown. New bus routes have been added to street transportation, with buses running at more times. Fares have also been significantly lowered, and the government hopes that locals will utilize public transportation rather than driving. In fact, depending on the number of their license plate, local vehicles are allowed on the street every other day. This is to reduce both air pollution and traffic in the city. Beijing also went as far as to inspect every car, giving vehicles that don’t pass the smog test a yellow sticker, preventing it from the streets until September 20. Vehicles coming from other cities will be turned away unless they acquire a “Green Olympic Pass.”

China as a whole is following suit. On June 1, the Chinese State Council prohibited all stores and markets from offering plastic bags for free. This regulation has reduced the use of plastic bags by a whopping 80 percent in department stores and supermarkets and 50 percent in farmers’ markets by the end of June. A department store in Beijing supported this change by offering an exchange program in the month of June, giving out reusable totes to customers that brought in 50 plastic bags. New event specific buildings have been built to support the Games, and one in particular, the Water Cube, is made of lightweight plastic on the exterior, which requires less structural support, and is a better insulator than glass. That saves an estimated 30 percent in energy costs. Other buildings use no-flush toilets, rooftop solar panels, and a rainwater collection system.

Even Video Games are Targeting Environmental Issues

“In a desperate, near future setting where controlling the planet’s depleting fossil resources determines the ultimate fate of civilization. A global war for oil is being waged between two superpowers, the Western Coalition (US/EU) and the Red Star Alliance (Russia/China).”Jane McGonigal was a speaker at South by Southwest this year. She’s a game designer and future forecaster who “takes play seriously.” Her day to day work is as senior researcher at the Institute for the Future (what a great name). Jane spends a majority of her time writing and speaking about the power of digital games, virtual environments and other immersive experiences. She believes that they can change our current reality and also shape our future. Her specialty is focusing on designing collaborative games that mesh the real world with virtual environments. Originally titled “World Without Oil”, Frontlines: Fuel of War is a collaborative online game simulating global oil shortage. It’s the first mainstream video game to capitalize on the worst case scenario of a global oil shortage. According to Craig Anderson, the game “could in fact lead to changes in attitudes, beliefs, and ultimately, changes in behavior.” Craig is a well established professor who teaches psychology at Iowa State University. He is a leading expert in the study of how video games effect people.

Algae Shines Bright on our Clothing

Photo credit: Juan Hinestrosa

We all know that traditional fabric dyes are toxic (heavy metals, synthetic chemicals) and wasteful (by-waste, and run-off). In the past couple of years, this problem has posed serious environmental issues in the textile industry. In the last year alone, prices on fabrics have risen due to efforts to mitigate environmental pollution in China.

Well fear not, help is on the way. British scientists and researchers at Oxford University have developed a way to color fabric with algae. The single-celled algae organisms, called diatoms, are composed of tiny little iridescent shells. Depending on the porous nature, these silica based shells reflect different colors that remain constant over time.

“As the paint dries, they will all align themselves horizontally at the surface, all reflecting light the same way,” said Andrew Parker, of Oxford to Wired Magazine. “So, even though you have completely transparent paint and completely transparent silica shells, they will produce a very strong color.” Thus color is created naturally without having to rely on any environmentally harmful synthetic chemicals.
