    MIT Climate “Plug-In” highlights first year of progress on MIT’s climate plan

    In a combined in-person and virtual event on Monday, members of the three working groups established last year under MIT’s “Fast Forward” climate action plan reported on the work they’ve been doing to meet the plan’s goals, including reaching zero direct carbon emissions by 2026.

    Introducing the session, Vice President for Research Maria Zuber said that “many universities have climate plans that are inward facing, mostly focused on the direct impacts of their operations on greenhouse gas emissions. And that is really important, but ‘Fast Forward’ is different in that it’s also outward facing — it recognizes climate change as a global crisis.”

    That, she said, “commits us to an all-of-MIT effort to help the world solve the super wicked problem in practice.” That means “helping the world to go as far as it can, as fast as it can, to deploy currently available technologies and policies to reduce greenhouse gas emissions,” while also quickly developing new tools and approaches to deal with the most difficult areas of decarbonization, she said.

    Significant strides have been made in this first year, according to Zuber. The Climate Grand Challenges competition, announced last year as part of the plan, has just announced five flagship projects. “Each of these projects is potentially important in its own right, and is also exemplary of the kinds of bold thinking about climate solutions that the world needs,” she said.

    “We’ve also created new climate-focused institutions within MIT to improve accountability and transparency and to drive action,” Zuber said, including the Climate Nucleus, which comprises heads of labs and departments involved in climate-change work and is led by professors Noelle Selin and Anne White. The “Fast Forward” plan also established three working groups that report to the Climate Nucleus — on climate education, climate policy, and MIT’s carbon footprint — whose members spoke at Monday’s event.

    David McGee, a professor of earth, atmospheric and planetary science, co-director of MIT’s Terrascope program for first-year students, and co-chair of the education working group, said that over the last few years of Terrascope, “we’ve begun focusing much more explicitly on the experiences of, and the knowledge contained within, impacted communities … both for mitigation efforts and how they play out, and also adaptation.” Figuring out how to access the expertise of local communities “in a way that’s not extractive is a challenge that we face,” he added.

    Eduardo Rivera, managing director for MIT International Science and Technology Initiatives (MISTI) programs in several countries and a member of the education team, noted that about 1,000 undergraduates travel each year to work on climate and sustainability challenges. These include, for example, working with a lab in Peru assessing pollution in the Amazon, developing new insulation materials in Germany, developing affordable solar panels in China, working on carbon-capture technology in France or Israel, and many others, Rivera said. These are “unique opportunities to learn about the discipline, where the students can do hands-on work along with the professionals and the scientists in the front lines.” He added that MISTI has just launched a pilot project to help these students “to calculate their carbon footprint, to give them resources, and to understand individual responsibilities and collective responsibilities in this area.”

    Yujie Wang, a graduate student in architecture and an education working group member, said that during her studies she worked on a project focused on protecting biodiversity in Colombia, and also worked with a startup to reduce pesticide use in farming through digital monitoring. In Colombia, she said, she came to appreciate the value of interactions among researchers using satellite data, with local organizations, institutions and officials, to foster collaboration on solving common problems.

    The second panel addressed policy issues, as reflected by the climate policy working group. David Goldston, director of MIT’s Washington office, said “I think policy is totally central, in that for each part of the climate problem, you really can’t make progress without policy.” Part of that, he said, “involves government activities to help communities, and … to make sure the transition [involving the adoption of new technologies] is as equitable as possible.”

    Goldston said “a lot of the progress that’s been made already, whether it’s movement toward solar and wind energy and many other things, has been really prompted by government policy. I think sometimes people see it as a contest, should we be focusing on technology or policy, but I see them as two sides of the same coin. … You can’t get the technology you need into operation without policy tools, and the policy tools won’t have anything to work with unless technology is developed.”

    As for MIT, he said, “I think everybody at MIT who works on any aspect of climate change should be thinking about what’s the policy aspect of it, how could policy help them? How could they help policymakers? I think we need to coordinate better.” The Institute needs to be more strategic, he said, but “that doesn’t mean MIT advocating for specific policies. It means advocating for climate action and injecting a wide range of ideas into the policy arena.”

    Anushree Chaudhari, a student in economics and in urban studies and planning, said she has been learning about the power of negotiations in her work with Professor Larry Susskind. “What we’re currently working on is understanding why there are so many sources of local opposition to scaling renewable energy projects in the U.S.,” she explained. “Even though over 77 percent of the U.S. population actually is in support of renewables, and renewables are actually economically pretty feasible as their costs have come down in the last two decades, there’s still a huge social barrier to having them become the new norm,” she said. She emphasized that a fair and just energy transition will require listening to community stakeholders, including indigenous groups and low-income communities, and understanding why they may oppose utility-scale solar farms and wind farms.

    Joy Jackson, a graduate student in the Technology and Policy Program, said that the implementation of research findings into policy at state, local, and national levels is a “very messy, nonlinear, sort of chaotic process.” One avenue for research to make its way into policy, she said, is through formal processes, such as congressional testimony. But a lot is also informal, as she learned while working as an intern in government offices, where she and her colleagues reached out to professors, researchers, and technical experts of various kinds while in the very early stages of policy development.

    “The good news,” she said, “is there’s a lot of touch points.”

    The third panel featured members of the working group studying ways to reduce MIT’s own carbon footprint. Julie Newman, head of MIT’s Office of Sustainability and co-chair of that group, summed up MIT’s progress toward its stated goal of achieving net zero carbon emissions by 2026. “I can cautiously say we’re on track for that one,” she said. Despite headwinds in the solar industry due to supply chain issues, she said, “we’re well positioned” to meet that near-term target.

    As for working toward the 2050 target of eliminating all direct emissions, she said, it is “quite a challenge.” But under the leadership of Joe Higgins, the vice president for campus services and stewardship, MIT is implementing a number of measures, including deep energy retrofits, investments in high-performance buildings, an extremely efficient central utilities plant, and more.

    She added that MIT is particularly well-positioned in its thinking about scaling its solutions up. “A couple of years ago we approached a handful of local organizations, and over a couple of years have built a consortium to look at large-scale carbon reduction in the world. And it’s a brilliant partnership,” she said, noting that details are still being worked out and will be reported later.

    The work is challenging, because “MIT was built on coal, this campus was not built to get to zero carbon emissions.” Nevertheless, “we think we’re on track” to meet the ambitious goals of the Fast Forward plan, she said. “We’re going to have to have multiple pathways, because we may come to a pathway that may turn out not to be feasible.”

    Jay Dolan, head of facilities development at MIT’s Lincoln Laboratory, said that campus faces extra hurdles compared to the main MIT campus, as it occupies buildings that are owned and maintained by the U.S. Air Force, not MIT. They are still at the data-gathering stage to see what they can do to improve their emissions, he said, and a website they set up to solicit suggestions for reducing their emissions had received 70 suggestions within a few days, which are still being evaluated. “All that enthusiasm, along with the intelligence at the laboratory, is very promising,” he said.

    Peter Jacobson, a graduate student in Leaders for Global Operations, said that in his experience, projects that are most successful start not from a focus on the technology, but from collaborative efforts working with multiple stakeholders. “I think this is exactly why the Climate Nucleus and our working groups are so important here at MIT,” he said. “We need people tasked with thinking at this campus scale, figuring out what the needs and priorities of all the departments are and looking for those synergies, and aligning those needs across both internal and external stakeholders.”

    But, he added, “MIT’s complexity and scale of operations definitely poses unique challenges. Advanced research is energy hungry, and in many cases we don’t have the technology to decarbonize those research processes yet. And we have buildings of varying ages with varying stages of investment.” In addition, MIT has “a lot of people that it needs to feed, and that need to travel and commute, so that poses additional and different challenges.”

    Asked what individuals can do to help MIT in this process, Newman said, “Begin to leverage and figure out how you connect your research to informing our thinking on campus. We have channels for that.”

    Noelle Selin, co-chair of MIT’s climate nucleus and moderator of the third panel, said in conclusion “we’re really looking for your input into all of these working groups and all of these efforts. This is a whole of campus effort. It’s a whole of world effort to address the climate challenge. So, please get in touch and use this as a call to action.” More

    Material designed to improve power plant efficiency wins 2022 Water Innovation Prize

    The winner of this year’s Water Innovation Prize is a company commercializing a material that could dramatically improve the efficiency of power plants.

    The company, Mesophase, is developing a more efficient power plant steam condenser that leverages a surface coating developed in the lab of Evelyn Wang, MIT’s Ford Professor of Engineering and the head of the Department of Mechanical Engineering. Such condensers, which convert steam into water, sit at the heart of the energy extraction process in most of the world’s power plants.

    In the winning pitch, company founders said they believe their low-cost, durable coating will improve the heat transfer performance of such condensers.

    “What makes us excited about this technology is that in the condenser field, this is the first time we’ve seen a coating that can last long enough for industrial applications and be made with a high potential to scale up,” said Yajing Zhao SM ’18, who is currently a PhD candidate in mechanical engineering at MIT. “When compared to what’s available in academia and industry, we believe you’ll see record performance in terms of both heat transfer and lifetime.”

    In most power plants, condensers cool steam to turn it into water. The pressure change caused by that conversion creates a vacuum that pulls steam through a turbine. Mesophase’s patent-pending surface coating improves condensers’ ability to transfer heat, thus allowing operators to extract power more efficiently.

    Based on lab tests, the company predicts it can increase power plant output by up to 7 percent using existing infrastructure. Because steam condensers are used around the world, this advance could help increase global electricity production by 500 terawatt hours per year, which is equivalent to the electricity supply for about 1 billion people.

    The efficiency gains will also lead to less water use. Water sent from cooling towers is a common means of keeping condensers cool. The company estimates its system could reduce fresh water withdrawals by the equivalent of what is used by 50 million people per year.

    After running pilots, the company believes the new material could be installed in power plants during the regularly scheduled maintenance that occurs every two to five years. The company is also planning to work with existing condenser manufacturers to get to market faster.

    “This all works because a condenser with our technology in it has significantly more attractive economics than what you find in the market today,” says Mesophase’s Michael Gangemi, an MBA candidate at MIT’s Sloan School of Management.

    The company plans to start in the U.S. geothermal space, where Mesophase estimates its technology is worth about $800 million a year.

    “Much of the geothermal capacity in the U.S. was built in the ’50s and ’60s,” Gangemi said. “That means most of these plants are operating way below capacity, and they invest frequently in technology like ours just to maintain their power output.”

    The company will use the prize money, in part, to begin testing in a real power plant environment.

    “We are excited about these developments, but we know that they are only first steps as we move toward broader energy applications,” Gangemi said.

    MIT’s Water Innovation Prize helps translate water-related research and ideas into businesses and impact. Each year, student-led finalist teams pitch their innovations to students, faculty, investors, and people working in various water-related industries.

    This year’s event, held in a virtual hybrid format in MIT’s Media Lab, included five finalist teams. The second-place $15,000 award was given to Livingwater Systems, which provides portable rainwater collection and filtration systems to displaced and off-grid communities.

    The company’s product consists of a low-cost mesh that goes on roofs to collect the water and a collapsible storage unit that incorporates a sediment filter. The water becomes drinkable after applying chlorine tablets to the storage unit.

    “Perhaps the single greatest attraction of our units is their elegance and simplicity,” Livingwater CEO Joshua Kao said in the company’s pitch. “Anyone can take advantage of their easy, do-it-yourself setup without any preexisting knowhow.”

    The company says the system works on the pitched roofs used in many off-grid settlements, refugee camps, and slums. The entire unit fits inside a backpack.

    The team also notes existing collection systems cost thousands of dollars, require expert installation, and can’t be attached to surfaces like tents. Livingwater is aiming to partner with nongovernmental organizations and nonprofit entities to sell its systems for $60 each, which would represent significant cost savings when compared to alternatives like busing water into settlements.

    The company will be running a paid pilot with the World Food Program this fall.

    “Support from MIT will be crucial for building the core team on the ground,” said Livingwater’s Gabriela Saade, a master’s student in public policy at the University of Chicago. “Let’s begin to realize a new era of water security in Latin America and across the globe.”

    The third-place $10,000 prize went to Algeon Materials, which is creating sustainable and environmentally friendly bioplastics from kelp. Algeon also won the $5,000 audience choice award for its system, which doesn’t require water, fertilizer, or land to produce.

    The other finalists were:

    Flowless, which uses artificial intelligence and an internet of things (IoT) platform to detect leaks and optimize water-related processes to reduce waste;
    Hydrologistics Africa Ltd, a platform to help consumers and utilities manage their water consumption; and
    Watabot, which is developing autonomous, artificial intelligence-powered systems to monitor harmful algae in real time and predict algae activity.

    Each year the Water Innovation Prize, hosted by the MIT Water Club, awards up to $50,000 in grants to teams from around the world. This year’s program received over 50 applications. A group of 20 semifinalist teams spent one month working with mentors to refine their pitches and business plans, and the final field of finalists received another month of mentorship.

    The Water Innovation Prize started in 2015 and has awarded more than $275,000 to 24 different teams to date. More

    A community approach to improving the health of the planet

    Earlier this month, MIT’s Department of Mechanical Engineering (MechE) hosted a Health of the Planet Showcase. The event was the culmination of a four-year long community initiative to focus on what the mechanical engineering community at MIT can do to solve some of the biggest challenges the planet faces on a local and global scale. Structured like an informal poster session, the event marked the first time that administrative staff joined students, researchers, and postdocs in sharing their own research.

    When Evelyn Wang started her tenure as mechanical engineering department head in July 2018, she and associate department heads Pierre Lermusiaux and Rohit Karnik made the health of the planet a top priority for the department. Their goal was to bring students, faculty, and staff together to develop solutions that address the many problems related to the health of the planet.

    “As a field, mechanical engineering is unique in its diversity,” says Wang, the Ford Professor of Engineering. “We have researchers who are world-leading experts on desalination, ocean engineering, energy storage, and photovoltaics, just to name a few. One of our driving motivations has been getting those experts to collaborate and work on new health of the planet research projects together.”

    Wang also saw an opportunity to tap into the passions of the department’s students and staff, many of whom devote their extracurricular and personal time to environmental causes. She enlisted the help of a team of faculty and staff to launch what has become known as the MechE Health of the Planet Initiative.

    The initiative, which capitalizes on the diverse range of research fields in mechanical engineering, encouraged both grand research ideas that could have impact on a global scale, and smaller personal habits that could help on a smaller scale.

    “We wanted to encourage everyone in our community to think about their daily routine and make small changes that really add up over time,” says Dorothy Hanna, program administrator at MIT and one of the staff members leading the initiative.

    The Health of the Planet team started small. They hosted an office supply swap day to encourage recycling and reuse of everyday office products. This idea expanded to include the launch of “Lab Reuse Days.” Members of the Rohsenow Kendall Lab, including members of the research groups of professors Gang Chen, John Lienhard, and Evelyn Wang, gathered extra materials for reuse. Researchers from other labs picked up Arduino kits, tubing, and electrical wiring to use for their own projects.

    While individuals were encouraged to adopt small habits at home and at work to help the health of the planet, research teams were encouraged to work together on solutions on a larger scale.

    Seed funding for collaborative research

    In early 2020, the MIT Department of Mechanical Engineering launched a new collaborative seed research program based on funding from MathWorks, the computing software company that developed MATLAB. The first seed funding supported health of the planet research projects led by two or more mechanical engineering faculty members.

    “One of the driving goals of MechE has been fostering collaborations and supporting interdisciplinary research on the grand challenges our world faces,” says Pierre Lermusiaux, the Nam P. Suh Professor and associate department head for operations. “The seed funding from MathWorks was a great opportunity to build upon the diverse expertise and creativity our researchers have to address health of the planet related issues.” 

    The research projects supported by the seed funding ranged from lithium-ion batteries for electric vehicles to high-performance household energy products for low- and middle-income countries. Each project differs in scope and application, and draws upon the expertise of at least two different research groups at MIT.

    Throughout the past two years, faculty presented about these research projects in several community seminars. They also participated in a full-day faculty research retreat focused on health of the planet research that included presentations from local Cambridge and Boston city leaders, as well as experts from other MIT departments and Harvard University.

    These projects have helped break down barriers and increased collaboration among research groups that focus on different areas. The third round of seed funding for collaborative research projects was recently announced and new projects will be chosen in the coming weeks.

    A community showcase

    Upon returning to the campus last fall, the Health of the Planet team began planning an event to bring the community together and celebrate the department’s research efforts. The Health of the Planet Showcase, which took place on April 4, featured 26 presenters from across the mechanical engineering community at MIT.

    Projects included a marine coastal monitoring robot, solar hydrogen production with thermochemical cycles, and a portable atmospheric water extractor for dry climates. Among the presenters was Administrative Assistant Tony Pulsone, who presented on how honeybees navigate their surroundings, as well as program manager Theresa Werth and program administrator Dorothy Hanna, who presented on reducing bottled water use and practical strategies developed by staff to overcome functional barriers on campus.

    The event concluded with the announcement of the Fay and Alfred D. Chandler Jr. Research Fellowship, awarded to a MechE student-led effort to propose a new paradigm to improve the health of our planet. Graduate student Charlene Xia won for her work developing a real-time opto-fluidics system for monitoring the soil microbiome.

    “The soil microbiome governs the biogeochemical cycling of macronutrients, micronutrients, and other elements vital for the growth of plants and animal life,” Xia said. “Understanding and predicting the impact of climate change on soil microbiomes and the ecosystem services they provide present a grand challenge and major opportunity.”

    The Chandler Fellowship will continue during the 2022-23 academic year, when another student-led project will be chosen. The department also hopes to make the Health of the Planet Showcase an annual gathering.

    “The showcase was such a vibrant event,” adds Wang. “It really energized the department and renewed our commitment to growing community efforts and continuing to advance research to help improve and protect the health of our planet.” More

    Strengthening students’ knowledge and experience in climate and sustainability

    Tackling the climate crisis is central to MIT. Critical to this mission is harnessing the innovation, passion, and expertise of MIT’s talented students, from a variety of disciplines and backgrounds. To help raise this student involvement to the next level, the MIT Climate and Sustainability Consortium (MCSC) recently launched a program that will engage MIT undergraduates in a unique, year-long, interdisciplinary experience both developing and implementing climate and sustainability research projects.

    The MCSC Climate and Sustainability Scholars Program is a way for students to dive deeply and directly into climate and sustainability research, strengthen their skill sets in a variety of climate and sustainability-related areas, build their networks, and continue to embrace and grow their passion.The MCSC Climate and Sustainability Scholars Program is representative of MIT’s ambitious and bold initiatives on climate and sustainability — bringing together faculty and students across MIT to collaborate with industry on developing climate and sustainability solutions in the context of undergraduate education and research.

    The program, open to rising juniors and seniors from all majors and departments, is inspired by MIT’s SuperUROP program. Students will enroll in a year-long class while simultaneously engaging in research. Research projects will be climate- and sustainability-focused and can be on or off campus. The course will be initially facilitated by Desiree Plata, the Gilbert W. Winslow Career Development Professor in Civil and Environmental Engineering, and Elsa Olivetti, the Esther and Harold E. Edgerton Associate Professor in Materials Science and Engineering and MCSC co-director.“Climate and sustainability challenges face real barriers in science, technology, policy, and beyond,” says Plata, who also serves on the MCSC’s Faculty Steering Committee. “We need to motivate an all-hands effort to bring MIT talent to bear on these challenges, and we need to give our students the tools to make tangible benefits within and between their disciplines. This was our goal in designing the MCSC Scholars Program, and it’s what I’m most excited about.”

    The Climate and Sustainability Scholars Program has relevance across all five schools, and the number of places the course is cross-listed continues to grow. As is the broader goal of the MCSC, the Climate and Sustainability Scholars Program aims to amplify and extend MIT’s expertise — through engaging students of all backgrounds and majors, bringing in faculty mentors and instructors from around the Institute, and identifying research opportunities and principal investigators that span disciplines. The student cohort model will also build off of the successful community-building endeavors by the MIT Energy Initiative and Environmental Solutions Initiative, among others, to bring students with similar interests together into an interdisciplinary, problem-solving space.The program’s fall semester will focus on key climate and sustainability topics, such as decarbonization strategies, policy, environmental justice, and quantitative methods for evaluating social and environmental impacts, and humanities-based communication of climate topics, all while students engage in research. Students will simultaneously develop project proposals, participate in a project through MIT’s Undergraduate Research Opportunities Program, and communicate their work using written and oral media. The spring semester’s course will focus on research and experiential activities, and help students communicate their outputs in entrepreneurial or policy activities that would enable the research outcomes to be rapidly scaled for impact.Throughout the program, students will engage with their research mentors, additional mentors drawn from MCSC-affiliated faculty, postdoctoral Impact Fellows, and graduate students — and there will also be opportunities for interaction with representatives of MCSC member companies.“Providing opportunities for students to sharpen the skills and knowledge needed to pioneer solutions for climate change mitigation and adaptation is critical,” says Olivetti. “We are excited that the Climate and Sustainability Scholars Program can contribute to that important mission.” More

    Embracing ancient materials and 21st-century challenges

    When Sophia Mittman was 10 years old, she wanted to be an artist. But instead of using paint, she preferred the mud in her backyard. She sculpted it into pots and bowls like the ones she had seen at the archaeological museums, transforming the earthly material into something beautiful.

    Now an MIT senior studying materials science and engineering, Mittman seeks modern applications for sustainable materials in ways that benefit the community around her.

    Growing up in San Diego, California, Mittman was homeschooled, and enjoyed the process of teaching herself new things. After taking a pottery class in seventh grade, she became interested in sculpture, teaching herself how to make fused glass. From there, Mittman began making pottery and jewelry. This passion to create new things out of sustainable materials led her to pursue materials science, a subject she didn’t even know was originally offered at the Institute.

    “I didn’t know the science behind why those materials had the properties they did. And materials science explained it,” she says.

    During her first year at MIT, Mittman took 2.00b (Toy Product Design), which she considers one of her most memorable classes at the Institute. She remembers learning about the mechanical side of building, using drill presses and sanding machines to create things. However, her favorite part was the seminars on the weekends, where she learned how to make things such as stuffed animals or rolling wooden toys. She appreciated the opportunity to learn how to use everyday materials like wood to construct new and exciting gadgets.

    From there, Mittman got involved in the Glass Club, using blowtorches to melt rods of glass to make things like marbles and little fish decorations. She also took a few pottery and ceramics classes on campus, learning how to hone her skills to craft new things. Understanding MIT’s hands-on approach to learning, Mittman was excited to use her newly curated skills in the various workshops on campus to apply them to the real world.

    In the summer after her first year, Mittman became an undergraduate field and conservation science researcher for the Department of Civil and Environmental Engineering. She traveled to various cities across Italy to collaborate with international art restorers, conservation scientists, and museum curators to study archaeological materials and their applications to modern sustainability. One of her favorite parts was restoring the Roman baths, and studying the mosaics on the ground. She did a research project on Egyptian Blue, one of the first synthetic pigments, which has modern applications because of its infrared luminescence, which can be used for detecting fingerprints in crime scenes. The experience was eye-opening for Mittman; she got to directly experience what she had been learning in the classroom about sustainable materials and how she could preserve and use them for modern applications.

    The next year, upon returning to campus, Mittman joined Incredible Foods as a polymeric food science and technology intern. She learned how to create and apply a polymer coating to natural fruit snacks to replicate real berries. “It was fun to see the breadth of material science because I had learned about polymers in my material science classes, but then never thought that it could be applied to making something as fun as fruit snacks,” she says.

    Venturing into yet another new area of materials science, Mittman last year pursued an internship with Phoenix Tailings, which aims to be the world’s first “clean” mining company. In the lab, she helped develop and analyze chemical reactions to physically and chemically extract rare earth metals and oxides from mining waste. She also worked to engineer bright-colored, high-performance pigments using nontoxic chemicals. Mittman enjoyed the opportunity to explore a mineralogically sustainable method for mining, something she hadn’t previously explored as a branch of materials science research.

    “I’m still able to contribute to environmental sustainability and to try to make a greener world, but it doesn’t solely have to be through energy because I’m dealing with dirt and mud,” she says.

    Outside of her academic work, Mittman is involved with the Tech Catholic Community (TCC) on campus. She has held roles as the music director, prayer chair, and social committee chair, organizing and managing social events for over 150 club members. She says the TCC is the most supportive community in her campus life, as she can meet people who have similar interests as her, though are in different majors. “There are a lot of emotional aspects of being at MIT, and there’s a spiritual part that so many students wrestle with. The TCC is where I’ve been able to find so much comfort, support, and encouragement; the closest friends I have are in the Tech Catholic Community,” she says.

    Mittman is also passionate about teaching, which allows her to connect to students and teach them material in new and exciting ways. In the fall of her junior and senior years, she was a teaching assistant for 3.091 (Introduction to Solid State Chemistry), where she taught two recitations of 20 students and offered weekly private tutoring. She enjoyed helping students tackle difficult course material in ways that are enthusiastic and encouraging, as she appreciated receiving the same help in her introductory courses.

    Looking ahead, Mittman plans to work fulltime at Phoenix Tailings as a materials scientist following her graduation. In this way, she feels like she has come full circle: from playing in the mud as a kid to working with it as a materials scientist to extract materials to help build a sustainable future for nearby and international communities.

    “I want to be able to apply what I’m enthusiastic about, which is materials science, by way of mineralogical sustainability, so that it can help mines here in America but also mines in Brazil, Austria, Jamaica — all over the world, because ultimately, I think that will help more people live better lives,” she says.

    Architecture isn’t just for humans anymore

    In a rural valley of northwestern Nevada, home to stretches of wetlands, sagebrush-grassland, and dozens of natural springs, is a 3,800-acre parcel of off-grid land known as Fly Ranch. Owned by Burning Man, the community that yearly transforms the neighboring playa into a colorful free-wheeling temporary city, Fly Ranch is part of a long-term project to extend the festival’s experimental ethos beyond the one-week event. In 2018, the group, in conjunction with The Land Art Generator Initiative, invited proposals for sustainable systems for energy, water, food, shelter, and regenerative waste management on the site. 

    For recent MIT alumni Zhicheng Xu MArch ’22 and Mengqi Moon He SMArchS ’20, Fly Ranch presented a new challenge. Xu and He, who have backgrounds in landscape design, urbanism, and architecture, had been in the process of researching the use of timber as a building material, and thought the competition would be a good opportunity to experiment and showcase some of their initial research. “But because of our MIT education, we approached the problem with a very critical lens,” says Xu, “We were asking ourselves: Who are we designing for? What do we mean by shelter? Sheltering whom?” 

    Architecture for other-than-human worlds

    Their winning proposal, “Lodgers,” selected among 185 entries and currently on view at the Weisner Student Art Gallery, asks how to design a structure that will accommodate not only the land’s human inhabitants, but also the over 100 plant and animal species that call the desert home. In other words, what would an architecture look like that centered not only human needs, but also those of the broader ecosystem? 

    Developing the project during the pandemic lockdowns, Xu and He pored over a long list of hundreds of local plants and animals — from red-tailed hawks to desert rats to bullfrogs — and designed the project with these species in mind. Combining new computational tools with the traditional Western Shoshone and Northern Paiute designs found in brush shelters and woven baskets, the thatched organic structures called “lodgers” feature bee towers, nesting platforms for birds, sugar-glazed logs for breeding beetle larvae, and composting toilets and environmental education classrooms for humans. 

    But it wasn’t until they visited Fly Ranch, in the spring of 2021, that Xu and He’s understanding of the project deepened. For several nights, they camped onsite with other competition finalists, alongside park rangers and longtime Burners, eating community meals together and learning first-hand the complexities of the desert. At one point during the trip, they were caught in a sandstorm while driving a trailer-load of supplies down a dirt road. The experience, they say, was an important lesson in humility, and how such extremes made the landscape what it was. “That’s why we later came to the term ‘coping with the friction’ because it’s always there,” He says, “There’s no solution.” Xu adds, “The different elements from the land — the water, the heat, the sound, the wind — are the elements we have to cope with in the project. Those little moments made us realize we need to reposition ourselves, stay humble, and try to understand the land.” 

    Leave no trace

    While the deserts of the American West have long been vulnerable to human hubris — from large-scale military procedures to mining operations that have left deep scars on the landscape — Xu and He designed the “lodgers” to leave a light footprint. Instead of viewing buildings as permanent solutions, with the environment perceived as an obstacle to be overcome, Xu and He see their project as a “temporary inhabitant.” 

    To reduce carbon emissions, their goal was to adopt low-cost, low-tech, recycled materials that could be used without the need for special training or heavy equipment, so that the construction itself could be open to everyone in the community. In addition to scrap wood collected onsite, the project uses two-by-four lumber, among the most common and cheapest materials in American construction, and thatching for the facades created from the dry reeds and bulrush that grow abundantly in the region. If the structures are shut down, the use of renewable materials allows them to decompose naturally. 

    Fly Ranch at MIT 

    Now, the MIT community has the opportunity to experience part of the Nevada desert — and be part of the process of participatory design. “We are very fortunate to be funded by the Council of the Arts at MIT,” says Xu. “With that funding, we were able to expand the team, so the format of the exhibition was more democratic than just designing and building.” With the help of their classmates Calvin Zhong ’18 and Wuyahuang Li SMArchS ’21, Xu and He have brought their proposal to life. The ambitious immersive installation includes architectural models, field recordings, projections, and artifacts such as the skeletons of turtles and fish collected at Fly Ranch. Inside the structure is a large communal table, where Xu and He hope to host workshops and conversations to encourage more dialogue and collaboration. Having learned from the design build, Xu and He are now collecting feedback from MIT professors and colleagues to bring the project to the next level. In the fall, they will debut the “lodgers” at the Lisbon Architectural Triennale, and soon hope to build a prototype at Fly Ranch itself. 

    The structures, they hope, will inspire greater reflection on our entanglements with the other-than-human world, and the possibilities of an architecture designed to be impermanent. Humans, after all, are often only “occasional guests” in this landscape, and part of the greater cycles of emergence and decay. “To us, it’s a beautiful expression of how different species are entangled on the land. And us as humans is just another tiny piece in this entanglement,” says Xu. 

    Established as a gift from the MIT Class of 1983, the Wiesner Gallery honors the former president of MIT, Jerome Wiesner, for his support of the arts at the Institute. The gallery was fully renovated in fall 2016, thanks in part to the generosity of Harold ’44 and Arlene Schnitzer and the Council for the Arts at MIT, and now also serves as a central meeting space for MIT Student Arts Programming including the START Studio, Creative Arts Competition, Student Arts Advisory Board, and Arts Scholars. “Lodgers: Friction Between Neighbors” is on view in the Wiesner Student Art Gallery through April 29, and was funded in part by the Council for the Arts at MIT, a group of alumni and friends with a strong commitment to the arts and serving the MIT community.
