How to print out your own house

2013-05-23T15:06:43Z

Architect Alastair Parvin came to TED2013 with questions that challenge our preconceptions about building. How about we involve everyone in the architectural design process, not just professional architects building for the super-wealthy? What about a world in which cities are built by citizens?

Alastair Parvin: Architecture for the people by the peopleParvin isn’t merely being rhetorical, as he shares in today’s talk. He and his London-based team have come up with a way to democratize both the design and the manufacturing of buildings. It’s called Wikihouse.

“The idea is to make it possible for anyone to go online and access a freely shared library of 3D models which they can download and adapt in Sketchup,” he says in today’s talk. “Almost at the click of a switch, they can generate a series of cutting files, which allow them in effect to print out the parts from a house using a CNC machine and a standard sheet material like plywood. The parts are all numbered, and basically what you end up with is a really big IKEA kit.”

Sounds intriguing… so how does it really work? We got Parvin to break it down, visually:

Wikihouse is an “open source construction kit.” It enables anyone with an Internet connection to access a shared library of structural designs.

Users simply choose a design. By clicking a button marked, “Make this house,” Wikihouse generates a set of cutting files for each of the parts that goes into that particular structure.

Using a CNC machine, the parts can be “printed” from a standard sheet material such as plywood.

All of the parts in the open source construction kit are numbered, and designed to minimize confusion. “The principles of openness go right to the mundane physical details,” Parvin says. “Don’t design a piece that can’t be picked up, and don’t design a piece that could be put in the wrong way around.”

The Wikihouse system is designed so that it slots together using wedges and pegs. Here’s another radical idea: even the tools used to make the house can be crafted using the Wikihouse technology. Design and manufacture your own mallet!

“People get confused between construction work and having fun,” jokes Parvin, who points out that before the Industrial Revolution, barn-raisings were a common occurrence. Why shouldn’t family and friends be involved in the construction of a modern house?

A building’s panels are screwed into place. A small team can complete a house structure in about a day. As Parvin lyrically describes, imagine “a future where the factory is everywhere, the design team is everyone.”

Mod cons might not be included in a Wikihouse, but they can certainly be incorporated. The frame of the house can easily be adapted to include the likes of cladding, insulation and windows as well as other amenities. Maybe one day, those will be downloadable files, too.

It’s still early days for the Wikihouse project (buildings take time to make, after all.) But here’s an intriguing timelapse video, filmed at the OUI Share Fest in Paris, which shows wiki-building at work.

TED news in brief: Esther Perel on female libido, an update on Henry Markram’s supercomputer brain, and more

2013-05-22T21:00:35Z

Below, take a look at some of the TED speakers and Fellows who are cropping up in the news this week.

Esther Perel: The secret to desire in a long-term relationshipLybrido, a drug to treat women with low libido, is in clinical trials and could be presented to the FDA for review as early as this summer. In The New York Times Magazine‘s look at this new drug, TED speaker Esther Perel is asked about the conundrum of desire for women in long-term relationships. “Many couples confuse love with merging,” she says. “This mix-up is a bad omen for sex. To sustain élan toward the other, there must be a synapse to cross. Eroticism requires distance.” Watch Perel’s talk “The secret to desire” »

Philosopher Dan Dennett has a great new book, Intuition Pumps and Other Tools for Thinking. Read an excerpt containing his “seven tools for thinking, or check out any of his four TED Talks »

Last week, NASA announced the shutdown of the Kepler spacecraft mission. On the TED Fellows blog, Lucianne Walkowicz – an astronomer who worked on the project – shares her thoughts on its end. Watch her talk “Finding planets around other stars” »

Henry Markram: A brain in a supercomputer The new Wired takes a detailed look at Henry Markram’s years-long campaign to build a supercomputer replica of the human brain — a plan he shared early on at TEDGlobal, in fact. The piece begins, “Even by the standards of the TED Conference, Henry Markram’s 2009 TEDGlobal talk was a mind-bender. He took the stage of the Oxford Playhouse, clad in the requisite dress shirt and blue jeans, and announced a plan that—if it panned out—would deliver a fully sentient hologram within a decade.” And it gets weirder. Watch his 2009 talk »

CERN physicists share with the TED-Ed blog what it was like to have their words — and sometimes their personas — animated in five TED-Ed videos that boil down concepts in particle physics into understandable terms. Watch these five animated lessons »

Rose George: Let's talk crap. Seriously.Related to Rose George’s talk, “Let’s talk crap. Seriously”: On Monday, in the state of Madhya Pradesh, India, 184 couples wed in a mass ceremony — before which the husband-to-be had to prove he had a toilet or would build one within the month. As a reward, The Wall Street Journal reports, “the state covers the costs of the wedding and gifts for the groom’s family, which are traditionally provided by the bride’s parents.” Watch George’s talk »

Finally, fashion website Refinery 29 admits that Meg Jay’s talk “Why 30 is not the new 20” got their “entire office buzzing.” Watch the talk »

TEDxSydney sets up at the Opera House: A timelapse

2013-05-22T20:28:00Z

On May 4, a TEDx event took place in one of the most architecturally recognizable sites in the world — the Sydney Opera House. Here, with the help of The MilkBar, the organizers of TEDxSydney captured the event from dawn to dusk and compressed it all into 78 seconds. Watch above as the sun rises over the beautiful building and as attendees arrive, fill the auditorium, enjoy speakers and head home again as the sun sets. Watch talks from the event »

And now for some slow-motion from TEDxSydney: A very cute video created for the event by Saatchi & Saatchi Sydney and Heckler called “The First Taste.” It shows young kids reacting to their first bites of foods of like anchovy, Vegemite and olives.

A library revolution, started in part by Jane McGonigal’s TED Talk

2013-05-22T20:27:51Z

Libraries are generally where you go to check out books; not where you go if you want to write one. This is an old assumption that Librii — a concept for a community-based, digitally-enhanced series of libraries in the developing world — would like to flip on its head. TED speaker Jane McGonigal has given this ambituous project a big thumbs up.

Librii is the brainchild of architect David Dewane, and aims to bring to Africa the kind of open information exchange and collaboration space that is easily found in highly-wired regions of the world. In Africa, only 3% of the population has access to broadband internet — but Librii isn’t just a place where people can go to connect to the internet and access online books and resources. Built by local workers and staffed by librarians, Librii will also focus on knowledge creation, compiling the ideas, insights and designs of the local community. It will even generate revenue for the community.

Librii was incubated with seed funding from the World Bank Institute and recently ran a successful Kickstarter campaign, raising more than $52,000 for its inaugural location in Accra, Ghana. So what does this have to do with video game designer Jane McGonigal?

Jane McGonigal: Gaming can make a better worldApparently, McGonigal’s 2010 TED Talk – “Gaming can make a better world” — planted the distant seed of this idea.

Dewane tells Metropolis Magazine that, after watching McGonigal’s talk, he began playing her online game EVOKE, which empowered players to solve social problems around the globe by developing real world ideas for projects that could have a big impact. About 15,000 project proposals were submitted through the game — and Dewane’s proposal for Librii was selected as one of 25 top possibilities.

McGonigal is very excited to see the idea materialize in reality.

“Librii fills me with almost a giddy anticipation for the future,” she tells Metropolis. “I can’t wait to see the creativity that flows out of Accra when young people are able to share their art and ideas with the rest of the world. Because I’ve backed the Kickstarter project, I’m a subscriber to the first connected library. I’ll get a digital copy of whatever gets created first—a book of advice or a collection of children’s stories. The library will encourage and inspire all kinds of creation.”

McGonigal is highly inspired to see her idea for a video game spin into a powerful idea that could affect the future of libraries. “It’s the power of TED,” she says.

The World on its Head: A Q&A about the ideas behind this exciting TEDGlobal session

2013-05-23T13:20:14Z

TEDGlobal 2013 guest curators Nassim Assefi and Gabriella Gomez-Mont share how they created the session, “The World on Its Head,” which will make you rethink the global order.

Session 6 of TEDGlobal 2013 has a captivating title: “The World on its Head.” Guest curated by Nassim Assefi and Gabriella Gómez-Mont — both from the inaugural class of TEDGlobal 2009 Fellows — the session will be a chance to turn our conceptions of the Middle East and Latin America upside down, and to rethink staid assumptions about politics, religion, art, architecture, peacemaking and more.

Here, the TED Blog asks Assefi and Gómez-Mont to share what inspired the session and how they went about picking speakers.

Where did the theme “The World on Its Head” come from?

Nassim Assefi: Gabriella and I brainstormed, trying to tie together our two regions. What is the zeigeist in each of our regions? The undercurrents? What do they have in common? How have they been underestimated? Misunderstood? What is their hidden potential? We settled on “The World On Its Head” after viewing a wonderful map of the world with the South facing upward. That visual became a metaphor for rethinking deeply held assumptions and views of the world and sitting with the discomfort of a new idea until the brain adjusts.

Gabriella Gómez-Mont: For me, the idea of “The World on Its Head” rings strongly and intimately with moments in life when I had to truly rethink important things so deeply that the former map no longer works, no longer matches the new reality. That moment, pause, gap, chaos of no longer understanding anything because one fundamental part of understanding crumbles — it’s one of the most enigmatic and profoundly human moments one can go through.

It is both so strangely beautiful and tremendously brutal to rethink once unshakable truths. No wonder all of us, collectively and individually, try to make the world sit still and force maps to remain the same for centuries even when they no longer work. But in the end, that moment of confusion is a fundamental part of every transformation, adventure, and reconstitution — a pure turbulent threshold between paradigms. And then many new possibilities surface after finding one’s footing again in an upside-down world.

How did the guest curation come about?

Assefi: I had been pitching speaker ideas to [TEDGlobal curator] Bruno Giussani since the moment I met him, and many of those suggestions have made it to the TED stage. I play that role at TEDMED, too. In August 2012, we received a marvelous email invitation out of the blue from Bruno to guest curate/host a session at TEDGlobal. There are more than 300 TED Fellows from around the world, each doing amazing work, and no TED Fellow had ever guest curated a session at TED, so this is an incredible honor.

Gabriella and I were chosen in part because we work in, and come from, distinct regions of the world — I represent the Middle East/Central Asia, and Gabriella Latin America. I’m an internist and global women’s health specialist (most recently tackling maternal mortality in Afghanistan). I also write novels, work on civic peace-oriented projects in the Middle East, defend human rights from a medical angle, and am a feminist activist, a single mom, and a diehard TEDhead. Gabriella is an artist, a documentary filmmaker, a curator for the arts in Latin America, and now head of a civic think tank/laboratory for Mexico City.

I represent the sciences/health, literature, and global politics; she is the arts expert, the design/architecture person, a cultural force. We have different styles of working, but in reality, we overlap quite a bit. I speak Spanish and have worked in Central America. She has traveled in the Middle East. We’re both polyglots, crazy dancers, and global citizens, though we have strong predilections for our regions of origin.

The map that inspired the session, “The World on its Head.”

What’s the thrust of the session?

Assefi: It’s about discarding assumptions about the Middle East, Latin America, and the way you think the world works in exchange for groundbreaking ideas that will hopefully inspire you to rethink politics, religion, art, peacemaking, the role of sports, underestimated economies and architecture, and even toxic environments.

Gómez-Mont: Exactly, that is a great description. I was interested in reformulating and rethinking certain gray areas we take for granted, and I wanted to focus on Latin America, on certain places and subjects that could be explored more thoroughly. We sought to make our speakers complement each other, understand how we could weave certain threads among individual narratives, regions and diverse disciplines. And diversity — of age, country of origin, religion, and so on — was important to us.

Can you describe your speakers?

Assefi: All are global citizens/multicultural. Each of them has taken on courageous work. The lineup include: architect and urbanist Teddy Cruz; explorer, writer and filmmaker Holly Morris; economic policy innovator Juan Pardinas; historian/political scientist Trita Parsi; performance artist Tania Bruguera; accidental theologist Lesley Hazleton; and founder of the Beirut Marathon, May El-Khalil.

We found our musician through two other TEDFellows, Meklit Hadero and Esra’a al Shafei. Dina el Wedidi is one of Meklit’s Nile Music artists and is featured in Esra’a’s MidEastTunes app. Through the Rolex Mentor and Protegee Arts Program, Dina has been paired with the famous Brazilian musician, Gilberto Gil. Dina seemed like a poetic fit for our session — the TED Fellow-link to discovering this brazen, beautiful, young woman singer-songwriter from the Middle East, who found her audience during the Arab Spring and is being influenced and mentored by a legendary Latin American musical force.

But we don’t want to give away our speakers’ topics. It’s more fun if you are surprised by our session. At a TED conference, one generally doesn’t know what each speaker’s idea worth spreading will be until show time!

Which speakers do you think are going to knock our socks off? Why?

Assefi: That’s a cruel question, like asking a mother to choose the favorite between her children! The truth is, if curated well, different speakers will wow different people. It depends on what’s happening in your life, what you’ve been thinking about lately, and how open you are to certain ideas. Of the four I’ve chosen, I can imagine each one of them blowing you away. I predict Gabriella feels the same.

Gómez-Mont: I feel the same. And one never knows until that fateful day when the crowd goes silent and the curtain goes up what will happen in that space between those words on paper and the voice on stage — between the careful planning and the happily reckless, often serendipitous, many times shifting, sometimes accomplice or sometimes trickster — reality.

TED Global, themed “Think Again,” kicks off on June 10 in Edinburgh, Scotland. See the full list of speakers, and get lots more information about attending at the conference website. And stay tuned to the TED Blog where we will be bringing you live coverage of the conference.

Crowdsourcing limitations: How you can become a part of Phil Hansen’s latest art piece

2013-05-22T20:27:24Z

As an artist, I’m always interested in looking at the defining moments in our lives, understanding how these moments affect us and finding different ways to represent them.

Phil Hansen: Embrace the shakeWe all face limitations. I had the amazing opportunity to share my story at the TED conference this year. I came to do the art I do today not by a well-defined path, but by a defining moment in my life when I learned to “embrace the shake.”

Ever since I started preparing this talk last year, I thought a lot about the limitations we deal with and how they define us. It made me question why they sometimes hold us back and, at other times, push us forward. I became very curious about this process, and I wondered: if we looked at all our limitations collectively, what kind of patterns would we see? And what kind of insights would we have? When we hear other peoples’ stories, we often see reflections of our own struggles, triumphs, fears and hopes, which can give us new perspectives.

So, I had the idea to give out my phone number – it’s 651-321-4996 — and ask people to share a story about a limitation they’ve faced in their life. Many of these stories will be written to create a singular piece of art — based on the photograph below, which I took years ago in Seattle during a time when my limitation held me back from doing art. Every time I look at it, it reminds me of being rudderless and gives me a sense that life is always shifting in turbulent beauty.

Anyone is welcome to watch via the live feed (check it out below, or through my personal website) as each story is written onto the canvas. In the end, there’s a greater story to be told as we reflect on the stories of our lives. On that note, the second part of this project is to bring out the essence of this shared art experience by filming it, and putting together a short documentary. I’m asking people to back it through Kickstarter and, in the end, want to share it with all of you online.

I started the art for this project on Thursday, May 16. So far, it has given me the opportunity to connect with people from all walks of life. Occasionally, when I’m busy, someone will call me endlessly — 15 times or more — because they just need to get it out of their system. It’s a lot to juggle sometimes, between talking to people, making the art, and filming for the short documentary. But so far, it’s worth it. Here are a few stories people have told me so far:

“I was told that my learning disability would make it difficult to finish college. Now I’m having to decide between attending Stanford and Harvard — both universities fighting over me for grad school.”

“My limitation is simply myself. I always question whether I’m good enough, smart enough, pretty enough, artistic enough. I’m my own worst critic, and I struggle with it everyday.”

“Sometimes I lay awake at night wondering what will happen to make me willing to make the HUGE lifestyle change that would be required to lose over 200 pounds.”

There are a couple of really interesting elements that have already revealed themselves in this process. Many of the people I’ve talked to often feel completely alone in their experiences — like no one could have possibly gone through what they have. But then I will run into another story that is very similar to theirs. If you boil it down to just the limitation, with all the personal details removed, what you’ll see are all of our core human experiences.

I hope that people who share their stories can get a different perspective by seeing the limitation that seems so massive become so small on this huge canvas. In the end, I hope that when anybody looks at the final art piece, they can find a story that they connect with.

Responding to the petition to disinvite George Papandreou from TEDGlobal

2013-05-21T12:37:26Z

An online petition was posted early this past weekend, asking that “the TEDGlobal conference organizers remove George Papandreou from the speakers list.”

Papandreou is the former prime minister of Greece. He was prime minister in 2009, when the euro crisis flared up. Under pressure from the markets and from Greek citizens protesting harsh austerity measures, he resigned in 2011 to make way for a national unity government.

He has been invited to share his views on these events and other themes at TEDGlobal 2013, which will take place in three weeks. With all due respect for those who have signed the petition, the TEDGlobal program won’t change. Papandreou’s experience as the PM of his country during a phase of political and economic turmoil is an interesting lens into the broader problems that continue to trouble Europe. That’s why we invited him to TEDGlobal. What he learned from his period in office gives him a rare insiders’ viewpoint, at a crucial moment for the continent.

For the record, any politicians coming to TED are asked to give a talk that is framed around ideas and insights, rather than partisanship. And like all our speakers, Papandreou is not being paid to speak at TEDGlobal.

North Korean defector Hyeonseo Lee reunited with the man who saved her family

A total stranger helped Hyeonseo Lee pay her mother and brother’s way out of jail as they fled from North Korea. Now, four years later, Lee has been reunited with that stranger, getting the chance to thank him in person.

Hyeonseo Lee: My escape from North KoreaIn Lee’s TED2013 talk, “My escape from North Korea,” she describes defecting from North Korea in the late ’90s and how, after nearly ten years of living in hiding, she returned to help her family make their own escape. When her mother and brother were captured in Vientiane, Laos, and jailed for illegal border crossing, Lee describes how, out of money and desperate for a solution, she was approached by a foreigner. After hearing Lee’s story, this stranger withdrew a large sum of cash — £645 to be exact — from an ATM. With the money to use as a bribe, Lee’s family was able to escape.

When Lee asked the stranger why he was helping her, he replied, “I’m not helping you. I’m helping the North Korean people.” As Lee says in an emotional moment in her talk, “The kind stranger symbolized new hope for me and the North Korean people when we needed it most.”

Earlier this month Lee was invited to be a guest on the Australian broadcast show Special Broadcasting Service (SBS), where she had an unexpected visitor: Dick Stolp, the Australian backpacker who had helped her in Laos. Lee didn’t have any of his contact information – but Stolp had seen her TED Talk and SBS, catching wind of the story, orchestrated the surprise reunion.

“I was really happy … I can’t explain with words, but it was really amazing,” Hyeonseo told Sky News after the reunion. “He says, ‘I’m not a hero,’ but I say he is a modern hero.”

Stolp, for his part, was excited to see the girl he had helped years ago. “You help a small hand and it reaches to other hands and you think, ‘That’s great, that’s good stuff,’” he said. “I’m meeting someone who is now doing good things, and inside I can’t help but feel ‘Hey! I helped this lady to go out and change her life.’”

Fuel cell symphonies and art from gift bag wrappers: The Reimagine Project launches with the TEDActive 2013 artists-in-residence

2013-05-22T20:27:09Z

Soft-spoken and self-effacing, Andy Cavatorta performed with punk bands in the early 1990s, has worked with Bjork and is a graduate of MIT’s Media Lab. His counterintuitive resume has led him to create these gigantic, aural structures — both meditative and comforting — which you can see here in a video the Lincoln Motor Company partnered with TED to produce.

After an exciting night of design-themed talks at TED@250, we unveiled this series of videos that profiles three artists who came to TEDActive 2013 to show their work: Aurora Robson, Andy Cavatorta, and Gilberto Esparza. The artists’ time at TED and the resulting short documentaries are part of the newly launched Lincoln Reimagine Project, which supports pioneering thinkers in the arts, design and innovation.

Why these three? Because they turn upside down the traditional ways we imagine music, sculpture and even recycling. At TEDActive, Robson, Cavatorta and Esparza showcased original works that disrupt cultural and environmental paradigms. The videos highlight their unique artistic philosophies.

Cavatorta, as he introduced himself to the audience, aptly philosophized: “I believe new instruments will lead the way to fertile and innovative territory, challenging composers to find new voices within new expressive dimensions and constraints… Because in an ever-changing world, sometimes the only way to say something true is to say something new. Or to say something old in a new way.”

Watch the following videos to see how Robson and Esparza have combined contemporary technology with formal constraints to give unique voice and shape to their respective work.

Polluted Art: Gilberto Esparza’s Fuel Cell Symphony
Gilberto creates a futuristic symphony made from plastic tubes, an iPad and bacteria.

Recycling Plastic into Art with Aurora Robson
Robson asked TED attendees to give her the plastic packaging from their gift bags, which she used as a medium to create an ethereal, floating sculpture.
