LAGI will be at the Living Product Expo September 17 & 18 (2015) at the Pittsburgh Convention Center.
The LAGI founding co-directors will be speaking at the event from 5:45–6:00 pm on Thursday the 18th.
The WindNest 1/4 scale prototype will be displayed along with several past LAGI submissions, showing the world that renewable energy can be beautiful.
About the WindNest Prototype
WindNest is designed by Trevor Lee of Suprafutures to passively rotate to face the wind just like a weather vane. To test the functionality and to experiment with the ball bearing mechanism design, a prototyping team under the direction of GTK Flow Analysis fabricated this 1/4 scale model and subjected it to a series of tests under different wind conditions and speed sequences.
The full-scale installation will incorporate a slip ring to allow for continuous rotation while conducting the electricity produced by the turbines and solar fabric.
The prototype also provides the opportunity to experiment with the structure of the cloud pods and will assist with the design of the fabric skin.
About the Living Product Expo
In early April, 2015, the Living Future Institute launched the Living Product Challenge. This new program re-imagines the design and construction of products to function as elegantly and efficiently as anything found in the natural world. The Living Product Expo is a groundbreaking new event that will bring together leading minds in the product industry and ignite a revolution in the way materials are designed, manufactured and delivered. Sustainability directors from the world’s leading design firms, prominent manufacturers and sustainability consultants will gather to learn about game-changing innovations in product design.
The Expo will assemble a diverse group of people, industries and disciplines. Together, we will engage in a transparent, transdisciplinary and transformative dialogue to inspire the creation of the world’s first Living Products. Participants will gain new tools, knowledge and connections to effect positive change in their organizations and supply chains.
The Living Product Expo is the world’s leading place for design and manufacturing professionals to learn about game-changing products that will transform the marketplace. It will be a unique opportunity for manufacturers and designers (of all sizes) to network, learn from one another and aggregate market power to create transformative impact. Attendees will experience a stimulating agenda of education tracks, inspiring keynote presentations, tours, networking and Show + Tell product demonstrations showcasing the latest trends in sustainable products.
For the past six weeks we have had the great fortune of spending every weekday with 20 of the most brilliant kids in Pittsburgh’s Homewood neighborhood. Yesterday, we all celebrated the final outcome of the Camp—Renaissance Gate, Pittsburgh’s newest work of public art and a 4.1 kWp solar energy installation on Frankstown Avenue.
The artwork helps to power to Homewood Renaissance Association’s new community center next door and provides passersby with a place where they can charge their cellphone during the day while catching some shade under the armatures of the installation.
The form of the artwork was inspired by the shape of the violet flower and by the way that the existing unused marquee at the site resembled a kind of gateway. The campers were already familiar with the concept of the Torii Gates of Japan, which symbolize a spiritual passage or journey. Renaissance Gate, the kids decided, would be a passageway to a new Homewood—a community of hope and progress, or what Free Blackwell, the Executive Director of Homewood Renaissance Association likes to call, “the most livable neighborhood in the most livable city.”
Pittsburgh Mayor Bill Peduto imparted even more meaning to the title of the artwork when he spoke at the August 13th opening ceremony just before cutting the red ribbon. He reminded us that the original renaissance in Europe marked a turning point from a period of fear and violence to a period of progress and hope in the future. It was the marriage of the arts and sciences that made Europe’s renaissance possible. The Art + Energy Summer Camp is an expression of the power of that combination and the importance of STEM to STEAM initiatives in education.
Over the course of the six week Camp the participants, ages 8–17, learned about energy science, art, and design.
Week one consisted of field trips to understand the existing landscape of energy production and consumption in Western Pennsylvania. We visited the Bruce Mansfield coal-fired power plant and the Beaver Valley nuclear power plant. We spent a day at Eden Hall, Chatham University’s sustainability campus where we saw a large solar installation at work and learned about solar thermal heat, aquaculture, and on-site wastewater treatment with engineered wetlands.
We visited Conservation Consultants Inc.’s building, one of Pittsburgh’s first green buildings, to learn about energy efficiency and to see their rooftop solar installations. We visited the new Energy Innovation Center to see their ice storage system and other advanced green building technologies. Other field trips included a visit to a local residential solar installation (thanks Fred Kraybill), and Construction Junction and Creative Reuse, where we learned about how to reduce waste streams and divert used goods and products from landfills.
Fun activities expanded vocabulary and engaged campers in the use of energy conversion efficiency and capacity factor to estimate the average annual output of energy installations.
Weeks two through five continued the lessons on art outside the gallery and the steps of the design process. At the same time the campers began to come up with their artistic concept and sketch the form of what would become the Renaissance Gate.
Some worked with paper and dowels on a 1” = 1’-0” scale model of the existing marquee. Others free-form designed with clay, while some of the older kids manipulated the solar panels in Google Sketchup.
A visit from David Edwards, a local artist and inventor, stimulated our imaginations with the endless possibilities of incorporating solar and wind power into artwork.
By the end of week three it was time to meet up with Tim Gerhart, the structural engineer, and Fred Underwood, the solar installer. Their input was invaluable as we worked together on the final design drawings.
During weeks four and five we were in full-swing with the fabrication and installation! VB Fabricators was able to deliver the finished structural steel armatures in a very short amount of time, and by the start of week six Underwood Solar was installing the solar panels and getting everything wired up. The campers really enjoyed being a part of the installation process, from framing up the panels to the aluminum rails, prepping the colorful panels, and even helping to dig the hole in the ground to examine the existing foundation (Imani and Terrell both found this to be their favorite part!).
We finished up just in time for the ribbon-cutting event with Mayor Peduto. We’re so glad that he was able to take the time out of his busy schedule to attend and speak on the importance of renewable energy and energy justice for communities like Homewood. Daniel Moore with the Pittsburgh Post Gazette wrote a great article that captures the energy of that wonderful day.
A highlight of the day’s festivities was a live performance of “Solar Energy” an original rap by Jordan Blackwell and DaVontae Garner. You’ll definitely want to give it a listen in the player below. It is a brilliant anthem for energy justice.
The kids have been a driving part of the entire process. They have helped with documentation, social media, design, and meetings with consultants. When challenges presented themselves, the campers were there helping us to brainstorm solutions. The outcome for them goes beyond this particular solar artwork. In a sense, we have graduated project managers. It’s our hope that they’ll be able to apply this experience in all walks of life.
And we hope that the Renaissance Gate will be cherished by the community as a symbol of what can be accomplished when we all work together towards a brighter future. As Mya Lane put it, “I feel the Renaissance Gate should inspire the community that in Homewood you don’t always have to use violence—and it’s a very nice community and it should be represented as one. The Renaissance Gate should stand for peace, non-violence, truth, justice. It should bring us and make us realize that we are all the same and one big family.”
We’re so grateful to our funders who made this project possible: Heinz Endowments, Google Community Grants, and Three Rivers Community Foundation.
Thanks to all of our camp participants: Jordan Blackwell, Canaan Blackwell, Adrian Nanji, Ewane Nanji, Thomas Bowens, Mya Lane, Sarai Robinson, Emani Jones, Elizabeth Blackwell, Jordan Woods, DaVontae Garner, Terrell Williams, Lamonte Farrish, Cameron Jennings, Madison Wilson, Erin Shealy, Caleb Williams, Imani Nanji, Elisha Blackwell, Jasmine Berry, with teachers Rodney Heard, Indigo Raffel, Robert Ferry, and Elizabeth Monoian.
Understanding this research coming out of Columbia University, might make your mind explode. The implications of this are potentially far-reaching, but the research is still in an early stage and just beginning to get public attention. It doesn’t even have a name really yet. How about “evaportricity”?
Wherever there is water there is evaporation. It happens all the time, sun up and sun down. It is a manifestation of the molecular energy that exists in all water above absolute zero. Until now, the power of this natural phenomenon has never been converted into other forms of energy. This new research is showing us that evaporation energy can be successfully converted to kinetic energy (and then into electrical energy) and that the technology can be scaled.
When evaporation energy is scaled up, the researchers predict, it could one day produce electricity from giant floating power generators that sit on bays or reservoirs, or from huge rotating machines akin to wind turbines that sit above water, said Ozgur Sahin, Ph.D., an associate professor of biological sciences and physics at Columbia University and the paper’s lead author.
“Evaporation is a fundamental force of nature,” Sahin said. “It’s everywhere, and it’s more powerful than other forces like wind and waves.”
As a side benefit to this new technology, wherever it is installed (ideally on the surface of a body of water) it keeps water in a closed loop without releasing it to the air. In other words, this technology could be installed on top of water reservoirs to generate electricity while also conserving water. They are still a long way from commercializing this, and they will need to move beyond the use of spores, but still it is impressive.
Who can imagine what these evaportricity infrastructures will look like when they are scaled up to power our cities?!
In Tehachapi California a new experiment in wind power is being tested. GE is applying a large dome at the rotor hub of three-blade horizontal axis wind turbines. The 60 ft. diameter space frame attachment channels the wind to the perimeter of the rotor where it produces more power.
The 20,000 lb structure can help to increase the power output of existing turbines by around 3%, which has the potential to bring the cost of wind power down significantly below its already low cost. Interestingly, it could also impact the form of future blades, allowing them to be designed for greater output without increasing the overall diameter of the rotor. This is important because the size of wind turbines has increased to the point where it is already very difficult to transport the blades to installation sites.
The ecoROTR is in some way like the Compact Acceleration Wind Turbine (CWAT) experiments that channel the wind to the blades from the perimeter of the rotor, but instead it is working at the center, which potentially means less material cost. The added material cost of the CWAT rings has made it difficult for them to compete in the marketplace.
Of course LAGI is in favor of the compact acceleration idea being applied to public art applications and many past LAGI submissions have incorporated some variation of it.
We’re really excited about this advancement. It’s not every day that there is such a dramatic shift in the form of wind turbine design. If the ecoROTR experiment proves successful it could have a reverberating impact on the design of our energy landscapes. As these new rotor hubs are added on and as blades take new shapes, future wind turbines may look very different than current models. The elegantly thin profile of today’s turbines are nice, but perhaps there are opportunities here for creativity?
We modified the image below just ever so slightly to get a feel for what might be possible for the turbine proboscis of the future!
We were awed yesterday on our way through El Paso, Texas yesterday when we drove through this dynamic piece that frames the I-10 corridor near the airport. It was that perfect time of day when the lighting was set off against a deep blue sky. The vertical axis wind turbines with overlapping blades in perspective provides a complicated visual moiré effect that reveals its secret as you pass through the installation.
Vortex Bladeless wind power is making big waves this week with articles in Wired and The Verge. Check out those articles for more information about the technology and some insightful comments from the Vortex team.
We’ve been following Vortex for some time with the hopes that 1. the full scale installations will be wildly successful, and 2. they will inspire creative applications of wind energy installations that can be placemaking contributions. Who wouldn’t want to hang out in a park with these simple and elegant objects?

We also think it’s interesting to compare the formal expression of a field of these Vortex Bladeless installations to that of The Lightning Field, 1977. Walter De Maria’s sublime land art work is the kind of art that inspired us to conceive of the Land Art Generator Initiative in 2008. The piece in the high desert of western New Mexico incorporates 400 polished stainless steel poles in a grid array measuring one mile by one kilometer. It is intended by the artist to be experienced over a long period of time and visits to the site require an overnight stay. While the gesture to the sky from the earth seems in our minds to be a temptation to lightning, we do not need to witness a lightning strike to have a full experience of the artwork.
We’re looking forward to the day that someone catches a photo of lightning striking the Vortex Bladeless array (although that will probably require some repair work).
Vortex Bladeless uses the phenomenon of vorticity to generate vibrations that are converted into electricity.
We are pleased to announce that in addition to our professional design competition in 2016 we will also be holding a special STEAM Prize for students. Get more information at http://youth.landartgenerator.org. And check back on August 15th to get started!
Thanks to all of our partners and to our wonderful team—experts in public art and education. Together we are getting ready for the August 15, 2015 launch of the complete Youth Design Brief and a complete Toolkit for Educators that will guide students and teachers through the design process from start to finish, and that is aligned with the most up to date educational standards in STEAM subjects.
The Toolkit will contain a series of fun activities like the LAGI Idea Generator Game that will help students design their own land art generator artworks. In addition to this Toolkit, we are available to help you every step of the way.
Bringing STEAM education to middle school and high school youth seamlessly through the arts is an engaging way to instill an early interest in the scientific method, provide useful technical skills, and introduce systems thinking. Our goal is to build a global community of young people who are inspired and equipped to design the landscape of our clean energy future.

Katie Henry is a super star teacher at Brookville Intermediate in Ohio. We have so much admiration and respect for her teaching strategies and we are learning a lot from our collaboration with her during the planning of our LAGI 2016 STEM educational outreach programming. If you want to learn more about cutting-edge educational leadership strategies, please take the time to watch this wonderful interview.
The WindNest team continues to grow and the project keeps getting better as the engineering details are worked out. Schematic design is now complete and the public approval process is underway with the City of Pittsburgh.
Trevor Lee at Suprafutures has done an excellent job of adapting the concept to its new site and the design continues to evolve in response to stakeholder and engineering feedback.
A revised completion date has been established for the Spring of 2016.
Please check back here for updates. We’ll provide a complete list of project partners and a detailed timeline once the project has the green light from the City.
We recently completed the fabrication of the prototype of one of the “nests” at approximately 1/4 scale. Thanks goes to Chris Williams at Steeltown Design for putting it together. We’ll begin testing as soon as the weather breaks in Pittsburgh. The results, along with a desktop computational fluid dynamic model analysis, will inform the next stages of design.
The prototype was built purely to measure performance. Lots of shortcuts in fabrication. Final version will look much more like the renderings and we are engineering the skin to not have the ribbing effect on the fabric.
Thanks to Deborah Hosking for shooting and editing this fun video of us moving the prototype to its winter storage location.
New Energies is the beautiful hardcover book that catalogs the LAGI 2014 design competition for Copenhagen. It is available at many bookstores, and online at such outlets as RIBA and Amazon.
The book contains engaging essays by Annette Skov (“The Glowing Island” A History of Refshaleøen); Laura Watts and Brit Ross Winthereik (“Energy as Alien”); Trine Plambech, Johanne Mose Entwistle, and Liselott Stenfeldt (“The Human Approach to Sustainability”); Peter Karnøe (“Danish Wind Power: A Journey Beyond Imagination” A History from 1893 to the Present); Chris Fremantle (“Working Together”); Else Marie Bukdahl (“Visual Art and the Ecological Challenge: About Some of the First Creators and Their Influence”); Lea Schick and Anne Sophie Witzke (“Generating Futures: LAGI as an Imaginatorium”); and an introduction by Elizabeth Monoian and Robert Ferry, the founding directors of LAGI.
It also illustrates 64 of the incredible proposals for energy-generating public artworks that came in from around the world in response to the LAGI 2014 open call.
The beautiful design is by Paul Schifino (Schifino Design), who also provided the graphic vision for the LAGI 2012 book, Regenerative Infrastructures.
On the Copenhagen harbor, across from the iconic Little Mermaid statue, lies an expanse of open land—a brownfield that is the oldest part of the former Burmeister & Wain shipbuilding yards. It’s the site of the third Land Art Generator Initiative design competition, which brings together creative minds from around the world in a collective effort to challenge our preconceptions of what renewable energy generation looks like. The Land Art Generator Initiative, or LAGI, was created to encourage the design and construction of public art installations that have the added benefit of utility-scale clean energy generation.
Sixty-four of the LAGI Copenhagen competition entries are profiled in this book through detailed spreads that include renderings, illustrations, and diagrams. Seven essays explore the role of creativity in the conception of new energy landscapes and provide insights into sustainable infrastructure innovations in Denmark. New Energies provides a much-needed case study on how we can transform our urban brownfields into aesthetic and functional destinations that power hundreds of homes while providing places for recreation and contemplation within our urban environments.
