Twine: Teaching your objects to speak

by Chris DeLuca

With its user-friendly interface, Twine is a small box that empowers non-programmers and those with limited coding knowledge to create their own DIY electronics projects.  Working out of the MIT Media Lab, John Carr and David Kestner designed the device to respond to a change in its environment and trigger a response or relay that information via text, Twitter, or email.

Twine is connected to a web application where users can input their desired variables. The simplified web app is a rules-based interface, which lets you quickly set up your notifications in real-time and take action once the variable has been met. The basic formula is: if something happens, then tell Twine to perform an action.  For example, if you set up Twine to notify you when the temperature in your house drops below a certain point, Twine can then be programmed to turn on your heating.

Collaboration alert: Sarah Fortune and Lukas Biewald

In 2010, Sarah Fortune came to PopTech looking for a solution. The 2010 PopTech Science Fellow and researcher at the Harvard School of Public Health had hit a wall in her research on Mycobacterium tuberculosis, the bacterium that causes tuberculosis. She needed a way to analyze streams of images of the bacteria -- as quickly and cheaply as possible -- or one line of her research would stall.

“I thought maybe we could crowdsource it,” she recalled in front of a packed house at PopTech 2011. “So I asked onstage, ‘Is there an app for that?’ Unbelievably, someone in the audience called out and then made it happen.”

That someone was Josh Nesbit, a 2009 Social Innovation Fellow, who connected Fortune to Lukas Biewald, co-founder of CrowdFlower, an Internet-based crowdsourcing company. The rest, as they say, is history.

To learn more about their collaboration, watch their PopTech 2011 talk or read the rest of this post from the conference.

Erik Hersman makes the case for Africa's upswing

In asking us to shed outdated notions of Africa as a place wracked by poverty and war, during his PopTech 2011 talk Erik Hersman (PopTech 2008 Social Innovation Fellow) lays out numerous examples of entrepreneurship and innovation streaming out of that continent, and specifically, out of Kenya.

Snowflakes made to order

When Kenneth Libbrecht utters the words “let it snow,” the universe obliges — even in southern California, even in the summer. Libbrecht is a physicist at Caltech, but he’s also a snowflake designer, manipulating water and air in his laboratory to produce the exquisite ice crystals we love to sing about —and to play about in — each winter.

But why? What secrets can a tiny, elemental snowflake yield to science today? As Libbrecht recently told the journal Nature (subscription required):

We see these beautiful structures falling from the sky, and we still cannot explain how they came to be. When you ask how snowflakes form, you are really asking about how molecules go from a disordered gaseous state to an ordered crystalline lattice. Unexpected phenomena can emerge — snowflakes are one fascinating example.

So his interest boils down to wanting to understand how crystals grow, the physics of which may find application in materials science. More specifically, Libbrecht is trying to understand why temperature has such a dramatic impact on the shape of snow crystals, producing simple, needle-like crystals at one temperature and extraordinarily complex, star-like ones at another. It's hard to believe, but the physics responsible for this transformation is still a mystery.

It should be said that Libbrecht’s interest in snowflakes isn’t purely academic. He’s an accomplished snowflake photographer, an author of several books on the icy crystals, and a pilgrim of sorts, who travels to snowflake “hot spots” – in Canada and Japan, for example – in search of the world’s best snow crystals. (Visit his website, SnowCrystals.com, for a flurry of facts and images about snowflakes including whether any two are the same.)

Following Pieter Hoff's efforts to combat desertification

We've been following the work of Pieter Hoff for some time now, along with his invention, the Groasis Waterboxx, a watering technology designed to grow trees in locations thought to be inhospitable. In fact, he first shared this invention and its potential impact with us at PopTech 2010.

During the conference, we spent some time with him one-on-one and made this candid video in which he explains how the Waterboxx works.

We followed up a handful of months later with an interview, On a mission with Pieter Hoff and his Groasis waterboxx, to learn more about how his relatively straight-forward contraption can bring an end to malnutrition, reduce erosion, and fight climate change.

So we were particularly excited to see this excellent piece entitled The Great Oasis (subscription required to read the entire article) in The New Yorker last week by PopTech friend Burkhard Bilger about efforts across the globe to reverse deforestation and desertification. In this thorough article, Bilger followed a few key players in the field of agroforestry to Oman and Burkino Faso, explored re-greening initiatives in Africa, and provided an historical overview of the Great Green Wall, a project involving 11 African countries planning to plant millions of trees to prevent the spread of the Sahara. On PopTech's recommendation, he spent time with Pieter Hoff in Oman to see first-hand what role the Waterboxx may play in replanting lost forests in some of the driest places on Earth.

The Hanging Garden: Detecting moisture levels with sensors and LED lights

by Chris DeLuca

The hanging garden, a collaboration between Clorofilas and Aer Studio, uses basic technological components to enable plants to communicate by placing sensors in their soil to detect moisture levels. The design studios, respectively based in Manchester and Barcelona, linked the sensors to LED lights that illuminate when moisture levels get too low and the plants need watering. The heart of the project, the open-source Arduino platform, takes the information received by the sensors and relays it to the corresponding LED light. This communication apparatus between plant and human life removes a variable of uncertainty when it comes to providing a plant with the right amount of water at the appropriate time.

The hanging garden project, which was created primarily for office spaces, also enables more effective communication amongst co-workers who assume responsibility for watering the plants; if a plant has already been watered earlier in the day, for example, co-workers in the afternoon will immediately know the plant is sufficiently hydrated. The technology used to create the hanging garden might be expanded and applied to projects which involve multiple stakeholders, like communal gardening initiatives.

Social innovation vs. cultural innovation

The term "social entrepreneur" has seen a lot of usage in recent years. Wikipedia defines a social entrepreneur as someone who "recognizes a social problem and uses entrepreneurial principles to organize, create and manage a venture to achieve social change". Many of PopTech's Social Innovation Fellows fall into this category.

A new, similar term has recently come into play: cultural entrepreneur. In a recent article by Courtney E. Martin and Lisa Witter published on Standford Social Innovation Review blog, the authors propose that cultural entrepreneurship be regarded as "social entrepreneurship's little sister."

From the article:

[W]e argue that cultural entrepreneurship is different than social entrepreneurship, because it is focused primarily on reimagining social roles and motivating new behaviors—often working with and in popular culture to reach the widest possible audience. Social entrepreneurs solve problems by disrupting existing systems, as microfinance has, or through breakthrough product design, like the solar powered lights from d.light design or Barefoot Power.

Cultural entrepreneurs, on the other hand, solve problems by disrupting belief systems—using television shows like Glee to initiate viewers into the disability or GLBTQ rights frameworks or the Twitter campaign #mensaythingstome, designed to expose anonymous misogyny online.

While it's true there are a plethora of new tools that enable a movement to bring its message to an intended audience, cultural entrepreneurship reads a bit like good old-fashioned activism.

What do you think? Has social entrepreneurship matured to the point where it's branching out its family tree, as the authors suggest? Or is cultural entrepreneurship just activism in a Tweet's clothing?
