A study by MIT researchers examining the carbon emissions of self-driving cars found that “the power required to run one billion driverless vehicles driving for one hour per day could consume as much energy as all existing data centers in the world,” reports Claire Brown for The New York Times. Graduate student Soumya Sudhakar explains that another big unknown is how autonomous vehicles could change the way people travel, adding to the uncertainty over the overall long-term emissions outlook for self-driving cars. 

CNN spotlights how MIT researchers have developed a new ultrasonic device that can extract clean drinking water from moisture in the atmosphere. “This method is much faster, we’re talking minutes instead of hours, compared to the old way,“ CNN explains. The new device “could be a game-changer in desert conditions, and for communities around the world that don’t have reliable access to drinking water.” 

Researchers at MIT have developed a new “system that uses a vibrating ceramic ring to produce clean drinking water from humid air in several minutes,” reports Matthew Burgos for DesignBoom. Burgos explains that with the system developed by MIT researchers, "clean water-making can take a few minutes versus the tens of minutes or hours required by thermal designs. In their system, the engineers use ultrasonic waves to shake the water out of the material that can absorb moisture from the air.” 

The MIT Sailing Pavilion will house the floating wetland - a pilot project aimed at finding ways to improve Charles River water quality and restore biodiversity - l for the winter season, reports Brianna Borghi for NBC Boston. “The Charles River Conservancy installed the 730-square-foot floating wetland in 2020 following years of research and development,” Borghi explains. “Under the surface, the floating wetland serves as a feeding ground for zooplankton, which help keep toxic algae blooms under control.” 

Yuly Fuentes-Medel of the MIT Climate Project speaks with Fast Company reporter Elizabeth Segran about how encouraging collaboration between shoe manufacturers could help increase shoe recycling. “The shoe industry is competitive, and these brands are rivals,” says Fuentes-Medel. “But by sharing costs, data, and infrastructure, they can achieve the sustainability goals that have eluded them for years.”

Stwart Peña Feliz MBA '23 co-founded MacroCycle, a startup that has “devised a way to pluck desirable synthetic fibers from waste textiles, leaving everything else behind,” reports Tim de Chant for TechCrunch. “MacroCycle differs because it doesn’t break down polymers,” explains Tim de Chant. “Instead, it loops the polymer chains back on themselves, forcing them into rings called macrocycles. Those macrocycles remain behind as different solvents wash away contaminants, which themselves could be recycled. Later, the rings are reopened to reform the polymer chain.” 

Prof. Peter Shor speaks with Katia Moskvitch and her nine-year-old son Kai of The Quantum Kid about how quantum technologies could be applied to developing climate change and sustainability solutions. Shor explains that quantum computers can be used for “simulating quantum mechanics, which would really help immensely in designing new materials, and new materials could be very useful for solving the climate crisis.” 

Researchers at MIT have developed a new method that can predict how plasma will behave in a tokamak reactor given a set of initial conditions, reports Gayoung Lee for Gizmodo. The findings “may have lowered one of the major barriers to achieving large-scale nuclear fusion,” explains Lee. 

Researchers at MIT have developed electron-conducting carbon concrete, a new kind of cement “that can store and release electricity like batteries,” reports Matthew Burgos for Design Boom. “MIT’s concrete battery shows a future where the material can be embedded into roads or parking areas to charge electric vehicles directly, or for off-grid homes that do not need external power,” Burgos explains.

Writing for the Financial Times, Principal Research Scientist Florian Berg explores “reasons to be hopeful about the resilience of efforts to tackle environmental issues at the corporate level.” Berg explains: “When looking at reporting on carbon emissions, ESG data and money invested in sustainable investment strategies, we can see big increases in recent years.” 

Leah Ellis, a former MIT postdoc and co-founder of MIT startup Sublime Systems, speaks with Nature reporter Jacqui Thornton about the creation of the company. “I felt that the word Sublime encapsulated the spirit of excellence, transcendence and purity that we intend to exemplify as we build a technology and a company that we hope will change the world — and the inherent properties of cement itself.” 

Noman Bashir, a fellow with MIT’s Climate and Sustainability Consortium, speaks with Smithsonian Magazine reporter Amber X. Chen about the impact of AI data centers on the country’s electric grid and infrastructure. Bashir notes “that the industry’s environmental impacts can also be seen farther up the supply chain,” writes Chen. “The GPUs that power A.I. data centers are made with rare earth elements, the extraction of which Bashir notes is resource intensive and can cause environmental degradation.” 

Prof. Caitlin Mueller has been named Innovator of the Year by Architectural Record for her work advancing a “vision for building design and construction that unites these disciplines with computation to create structure that are sustainable, high performing, and delightful,” reports Architectural Record. “Her group develops computational design and digital fabrication methods that integrate efficiency, performance, material circularity, and architectural expression,” Architectural Record notes. “This work spans robotic assembly of optimized trusses, fabrication of low-cost earthen and concrete systems, and algorithmic strategies for reusing salvaged wood and reassembled concrete parts.” 

The MIT Museum presents “Remembering the Future,” a new installation by artist Janet Echelman in collaboration with Prof. Caitlin Mueller, reports Kat Barandy for DesignBoom. The installation suspends above the museum’s grand lobby and will be open to the public through fall 2027. “The work transforms climate data into a three-dimensional form that invites visitors to engage both visually and conceptually,” Barandy explains.

In an opinion piece for the Financial Times, Prof. Evan Lieberman, director of the MIT Center for International Studies, spotlights how states, cities, corporations, and civil society are working to advance climate action. “Today, over 300 U.S. cities have made climate commitments, action plans, or are participating in co-operative initiatives,” Lieberman writes, “Large cities are connecting with global partners through organizations such as C40 Cities, a group of mayors representing some 700mn people worldwide.”
