Cool New Sponges Can Recycle CO2 Into Fuel

UnknownWhen your ice tea overflows the cup, forming a puddle on the counter, how do you clean it up? A sponge of course. Now scientists are working to see if the same idea will work with all that excess carbon dioxide that’s swirling around in our atmosphere.

Researchers at Australia’s national science agency, CSIRO, are developing a smart material called a MOF (metal organic framework) that could make it possible to capture C02 without using further coal-based energy. Using only the power of sunlight, these ‘solar sponges’ could be a new way to recycle carbon emissions without creating more in the process.

Traditionally, carbon dioxide capture has been accomplished through the use of liquid absorbers to catch flue gases at a coal-fired power plant before they escape into the atmosphere. The gases must then be heated to release the CO2 which is then stored and can be re-used. While slightly better than letting pollutants fly free, this process can consume as a much as 30 percent of a power plant’s production capacity. Not exactly efficient, especially when talking about power from fossil fuels.

In comparison, the CSIRO team uses a process called dynamic photo-switching, which refers to the reversible light-induced switching of floor or intensity. Instead of using liquid absorbers, the team used MOFs to absorb as much as a liter of nitrogen gas in just one gram of material. The unique material only requires UV light to trigger the release of CO2 after it has been captured from the mixture of exhaust gases. When exposed to concentrated UV light the MOF sponge instantaneously releases up to 64 percent of absorbed CO2, which can then be recycled into usable fuel.

“The capture and release process can be compared to soaking up water with a sponge and then wringing it out. When UV light hits the material its structure bends and twists and stored gas is released,” said Dr Matthew Hill, who was awarded a 2012 Eureka Prize for his MOF research and led the CSIRO group conducting this research. ”This is an exciting development for carbon capture because concentrated solar energy can be used instead of further coal-based energy to driv

An Eco-Fairy Tale: Beats of the Southern Wild

If you care about how global warming is changing our world for the worst; if you mourn the ghosts of animals like the dodo who no longer roam the earth due to human folly; if you still feel outrage about how the poor, the elderly, the sick, the vulnerable were left behind to die after Hurricane Katrina struck New Orleans in 2005, then you need to see Beasts of the Southern Wild, an indie film that has received Oscar nominations for Best Picture, Best Actress, Best Director and Best Adapted Screenplay.

The very title of director Benh Zeitlin’s first film about a young girl, 6-year-old Hushpuppy (Quvenzhané Wallis, who received the nomination for Best Actress) and her hard-drinking father, Wink (Dwight Henry) suggests that Beasts of the Southern Wild isn’t going to be ye average Hollywood blockbuster.

 

A “Coming-of-Age” Movie

Words like “mythic,” ”surreal,” “dreamlike” and “metaphysical fairy-tale” have been used to describe Beasts of the Southern Wild and for good reason.

The movie is centered around Hushpuppy, who lives in the Bathtub, a fictional community in the Louisiana bayou. She and Wink occupy a shack and trawl the bayou’s waters for food in a vessel that seems to be made of debris. With a big storm on the way and her father succumbing to an illness that leaves him shaking on the ground, Hushpuppy finds her life thrown into chaos.

Hushpuppy tries to understand all this by making up a story about a girl (also named Hushpuppy), her father and a mother (Hushpuppy’s own has gone missing). Her fears are portrayed as aurochs, giant beasts who once existed and are now extinct.

A Fable About Climate Change

With its focus on its young protagonist, Beasts of the Southern Wild has been called a coming-of-age drama. However, it is just as much an “eco-threat movie” that shows how extreme weather events can alter the world as we know it, forever.

The movie set in southern Louisiana and more than a few statements about climate change are placed in Hushpuppy’s mouth. “Everything has to fit together just right. If it doesn’t, it all falls apart,” she says. These words can be applied to a discussion about how our burning of fossil fuels can be linked to the the lessening sea ice in the Arctic and other world-wide effects of global warming.

Hushpuppy and the Aurochs

As the movie draws to a close, Hushpuppy confronts her fears for her father and about the storm by standing up to a herd of aurochs, the “beasts of the southern wild.” As director Zeitlin says, Hushpuppy is

… recognizing the harmony that she’s always talked about in nature. Everything is its own being. There is a natural point at which organisms in nature show weakness and allow for each other to exist—the same way she learns from her friends in The Bathtub [the fictional Louisiana community where Hushpuppy and her father live] to take care of each other. The aurochs recognize her as a similarly ferocious beast. And so they give way.

Beasts of the Southern Wild leaves its viewers with a challenge. The movie urges us to acknowledge the inter-connectedness between the pieces of the universe — by showing how, for a young child, the terminal illness of a parent and an imminent natural disaster are experienced as one and the same – and also to confront and deal with them.

If a 6-year-old girl can stand up to a herd of giant beasts, can we not do the same with all that threatens our world, be it global corporations seeking to drill further and deeper into the earth and under the sea for oil, or climate change deniers who pounce on a cold winter as “evidence” that global warming is just a myth?

What is the lifespan of a laptop?

Courtesy by: Lucy Siegle The Guardian

Commiserations on your laptop, although I’m afraid to say five years could be considered a good innings. It’s at the outer edge of what is considered the lifespan of a desktop computer (three to five years). Meanwhile it’s difficult to specify the lifespan of laptops, as they are so often junked before they are broken. This is in part due to planned obsolescence – a devious ploy by manufacturers bolstered by marketing strategies to make us fall out of love with a product hastily. In IT planned obsolescence has been turbocharged by must-have software which is only upwardly compatible. Want better software? You’ll need a better machine.

Planned obsolescence’s running mate is Moore’s law, which decrees that every two years the computing world doubles the amount of transistors on a computer chip and therefore the power of the computer. So you might say the average lifespan of a laptop is two years. Gulp. I have previously described the resources needed to make a computer,but here’s a recap: one metric tonne of electronic scrap from personal computers contains more gold than that recovered from 17 tonnes of gold ore.

Where will it all end? Moore’s law should see transistors miniaturising every two years until we reach technological singularity – the point at which computers gain human-level intelligence and can build better versions of themselves. Others think time will soon be up on Moore’s law, as computers will run out of matter and energy – by 2007 computers were reckoned to be drawing 4-5% of the world’s power. Heat is the enemy of Moore’s law. Those transistors packed on chips must be kept cool, so must the vast data storage centres, whose energy consumption, in 2010, was growing by 12% a year.

We need to keep our cool, too. There’s a huge amount of skill and knowledge online about how to make old computers worth their weight in gold. People who have dealt with IT for not-for-profits where there has never been much money for shiny new IT are particularly expert. TryItforcharities.co.uk for a list of organisations waiting to take on your “obsolete” model and Jayne Cravens’ postings on “old tech” atcoyotecommunications.com.

An untold truth is that we use a tiny fraction of each computer’s capacity: you could say we’re already outwitted by them. Unless we wise up we’ll soon be overtaken by the machines.

“Before I Die…” An Inspiring Community Art Project

It’s easy to get caught up in the day-to-day and forget what really matters to you. With help from old and new friends, Candy turned the side of an abandoned house in her neighborhood in New Orleans into a giant chalkboard where residents can write on the wall and remember what is important to them. Before I Die is an interactive public art project that invites people to share their hopes and dreams in public space. Painted with chalkboard paint and stenciled with the sentence “Before I die I want to _______”, the wall becomes an enlightening way to understand  your neighbors and discover what matters most to the people around you. It creates a public space for contemplation and reminds us why we want to be alive in the world today. It’s a question that changed Candy after she lost someone she loved very much, and she believes the design of our public spaces can better reflect what matters to us as a community and as individuals. This was the basis for her graduate thesis.

The responses have ranged from the funny and creative to the thoughtful and heartbreaking: Before I die I want to… sing for millions, see my daughter graduate, eat a salad with an alien, straddle the International Date Line, see the leaves change many times, be someone’s cavalry, cook a souffle, hold her one more time, help numerous children, see what I’m like as an old man, tell my mother I love her, make peace with Ohio, abandon all insecurities, be completely myself…  The project was featured in Oprah Magazine and NBC’s Rock Center with Brian Williams, and The Atlantic called it “one of the most creative community projects ever.”

After receiving many requests from people around the world, she and her Civic Centre colleagues created a new project site and a Before I die Toolkit to help you create a wall with your community! Thanks to your passion, this wall is turning into a global participatory art project and expanding to cities around the world, including Amsterdam, Portsmouth, Querétaro, Almaty, San Diego, Lisbon, Brooklyn, London, and beyond. You can also take a piece of the dream home with you with a limited edition painting and submit your dreams on the project site. The project is growing every day and together we can make public spaces that encourage us to reflect and lead better lives. Visit beforeidie.cc for more.

The Urban Weaver Project

The Vancouver Parks and Recreation Board is pleased to announce a new environmental art project in MacLean Park Fieldhouse presented in partnership with the Stanley Park Ecology Society, The Urban Weaver supports artists from diverse traditions working with ecologists exploring the creative repurposing of green waste.

The Urban Weaver:

Todd Devries  (Haida), Sharon Kallis (Welsh) and Debra Sparrow (Musqueam) are local artist-weavers collaborating with the Stanley Park Ecology Society and the Vancouver Park Board in an exploration of how invasive plants in the city can be used as urban substitutes for traditional weaving materials. English ivy, Himalayan blackberry, and yellow flag iris hold great potential as contemporary alternatives,  replacing materials such as cedar bark and cattails that cannot be sustainably harvested in urban centres. The artists will be working out of the MacLean Park Fieldhouse, near the Strathcona Community Centre, and there will be open studio times and free community workshops scheduled for next spring and summer. Community members can also get involved in harvesting and preparation of the invasive materials for personal creative use. This exciting project is just getting started so please stop by MacLean Park and meet the artists.

This project aligns with Park Board’s Strategic Priorities regarding ‘Greening’, ‘Engaging People’ and ‘Resource Management’ and responds to recent motions in support of the creative management and repurposing of both green waste and surplus spaces.

Green Home Design = Prefab Housing!

This past weekend, at the BC Home and Garden Show, there definitely seemed to be a trend of eco-friendly and sustainable design ideas, but the most interesting display had to be “The Kitsilano”, a prefab home built by Karoleena Homes (www.karoleena.com) from here in Vancouver.  This 1450 square foot open plan one bedroom home featured modern design and is one of the most eco-friendly homes you’ll find.
Prefabricated (or modular homes) are a great alternative to conventional home building.  They are built in a climate controlled factory environment and are assembled on site in a matter of days.  This saves on construction costs and reduces the impact to the surrounding environment, as there is less traffic from trades and vehicles to the site.  Design and factory construction can take as little as 3 months to complete and there is virtually no construction waste as everything is designed and built indoors.

There are, of course many misconceptions and speculations about prefab housing, including size and durability of the product, but many companies have been working for years on perfecting the engineering and design to make this a more conventional way to build homes.  Another common thought on prefab housing is that it costs far more than conventional home building, but increased demand is driving costs down, as well as the fact that a more energy efficient home will decrease day to day living costs.

Prefabricated homes have steel frames and are built to withstand transportation to the building site, so in most cases, they are stronger than most wooden frames homes.  Many prefab homes are built to include energy efficient products like induction stove tops, energy efficient appliances and the use of local building materia.  Solar photovaic panels, geothermal heat pumps and rainfall catchement systems are also becoming more mainstream and popular to use in prefab designs.

Ikea is also launching a prefab home that will be available in North Amercica for approximately $85, 000, making it a very affordable option.   Companies like Karoleena Homes and Ikea are definitely paving the way for home building of the future and promoting energy efficient and eco-friendly design that is available for everyone.

What is Art Therapy?

Definition: Art therapy is a form of expressive therapy that uses the creative process of making art to improve a person’s physical, mental, and emotional well-being.

The creative process involved in expressing one’s self artistically can help people to resolve issues as well as develop and manage their behaviors and feelings, reduce stress, and improve self-esteem and awareness.

Anyone can use it, you don’t need to be talented or an artist, and there are professionals that can work with you and delve into the underlying messages communicated through art.

Art therapy can achieve different things for different people. It can be used for counseling by therapists, healing, treatment, rehabilitation, psychotherapy, and in the broad sense of the term, art therapy can be used to massage one’s inner-self in a way that may provide the individual with a deeper understanding of him or herself.

Who Can Use Art Therapy?

For the most part, anyone can use art therapy. In a world where there is a multitude of ways to communicate and express one’s self, expressive arts therapy is yet another. One of the major differences between art therapy and other forms of communication is that most other forms of communication elicit the use of words or language as a means of communication. Often times, humans are incapable of expressing themselves within this limited range.

One of the beauties of art as therapy is the ability for a person to express his/her feelings through any form of art. Though there are other types of expressive therapies (such as the performing arts), expressive art therapy as discussed here typically utilizes more traditional forms of art…such as painting, drawing, photography, sculpture, or a variety of other types of visual art expression.

Do You Need to be Talented?

Absolutely not. And you need not be “afraid” of expressing yourself through art. Though it may seem different and unnatural at first, it is typically because the individual is not used to communicating via the arts. The creative process can be one of the most rewarding aspects. Coupled with an art therapist, you should gradually, if not immediately, feel comfortable with this newfound form of expression. After all, the goal is not necessarily to create an art masterpiece.

Why Would I Use Art Therapy?

As with most any therapy, art as therapy is generally used as a treatment for something – usually as a way to improve one’s emotional state or mental well-being. Expressive arts therapy doesn’t have to be used only as a treatment though. It can be used to relieve stress or tension, or it can be used as a mode of self-discovery. Many people can stand to use some sort of creative outlet.

Professional Art Therapy and Art Therapists

Art therapists are trained in therapy and art. They have studied and mastered psychology and human development. Art therapists typically have a clinical practice of some sort. They are masters in this niche when it comes to using art as a springboard for everything from a general assessment of another person’s state to treatment for a serious illness. Art therapists can work with people of all ages, sex, creed, etc. They can help an individual, a couple, a family, or groups of people. Depending on the situation, there may be numerous art therapists working together as a clinical team.

Art therapists are trained to pick up on nonverbal symbols and metaphors that are often expressed through art and the creative process, concepts that are usually difficult to express with words. It is through this process that the individual really begins to see the effects of art therapy and the discoveries that can be made.
