Infrastructure

Writing for The Hill, Principal Research Scientist Randolph Kirchain and Research Scientist Hessam Azarijafari address how the condition of the nation’s road system impacts transportation emissions. “Investing in a higher-performance road system is a lever within state control that will improve the efficiency and carbon emissions of all vehicles, regardless of how each is powered,” write Kirchain and Azarijafari. “Smoother, stiffer roads allow cars to travel along it more efficiently. Every time a car tire traverses a bump, crack, or pothole, energy is wasted.”

Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.

MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.

In an article about how researchers are exploring why ancient Roman and Mayan buildings are still standing, AP reporter Maddie Burakoff highlights how researchers from MIT found that an ancient Roman technique for manufacturing concrete gave the material “self-healing” properties. “We don’t need to make things last quite as long as the Romans did to have an impact,” says Prof. Admir Masic. “If we add 50 or 100 years to concrete’s lifespan, “we will require less demolition, less maintenance and less material in the long run.”

Senior Lecturer and Senior Research Associate Fred Salvucci BS '61 SM '62 speaks with GBH’s The Big Dig Podcast host Ian Coss about his role in Boston’s “Big Dig” project. “The idea for the Big Dig began with an unlikely friendship,” explains Coss. “During the highway debates in the early 70s, Fred Salvucci – one of the highway opponents – went to a ton of meetings. And across the table at many of those meetings was a man named Bill Reynolds; he was there to represent the road builders.”

Professor Karilyn Crockett speaks with GBH’s The Big Dig Podcast host Ian Coss about the impact of The “Big Dig” – Boston’s highway project – on the city, its people and urban planning. Crockett “argues that despite all the incentives to build, build, build, the costs of that building would eventually force city residents to think the unthinkable,” says Coss. “So the anti-highway fight becomes a moment of imagining possibilities,” says Crockett. 

Researchers at MIT have developed a supercapacitor, an energy storage system, using cement, water and carbon, reports Macie Parker for The Boston Globe. “Energy storage is a global problem,” says Prof. Franz-Josef Ulm. “If we want to curb the environmental footprint, we need to get serious and come up with innovative ideas to reach these goals.”

Fast Company reporter Adele Peters writes that MIT researchers have developed a new type of concrete that can store energy, potentially enabling roads to be transformed into EV chargers and home foundations into sources of energy. “All of a sudden, you have a material which can not only carry load, but it can also store energy,” says Prof. Franz-Josef Ulm.

MIT engineers have uncovered a new way of creating an energy supercapacitor by combining cement, carbon black and water  that could one day be used to power homes or electric vehicles, reports Jeremy Hsu for New Scientist. “The materials are available for everyone all over the place, all over the world,” explains Prof. Franz-Josef Ulm. “Which means we don’t have the same restriction as with batteries.”

MIT researchers have discovered that when combined with water, carbon black and cement can produce a low-cost supercapacitor capable of storing electricity for later use, reports Andrew Paul for Popular Science. “With some further fine-tuning and experimentation, the team believes their enriched cement material could one day compose portions of buildings’ foundations, or even create wireless charging,” writes Paul.

Researchers at MIT have found that cement and carbon black can be combined with water to create a battery alternative, reports Robert Service for Science. Professor Franz-Josef Ulm and his colleagues “mixed a small percent of carbon black with cement powder and added water,” explains Service. “The water readily combines with the cement. But because the particles of carbon black repel water, they tend to clump together, forming long interconnected tendrils within the hardening cement that act like a network of wires.”

Researchers at MIT have discovered what makes ancient Roman concrete “exponentially more durable than modern concrete,” reports Jim Morrison for Wired. “Creating a modern equivalent that lasts longer than existing materials could reduce climate emissions and become a key component of resilient infrastructure,” writes Morrison.

Prof. David Hsu speaks with WBUR reporter Paula Moura about the importance of providing equitable access to electric vehicle charging stations. “The city definitely should provide equal access to services to everybody,” says Hsu. “There are barriers to doing that, but the government’s job is to overcome those barriers for everybody.”

MIT researchers have discovered that ancient Romans used calcium-rich mineral deposits to build durable infrastructure, reports Daniel Cusick for Scientific American. This “discovery could have implications for reducing carbon emissions and creating modern climate-resilient infrastructure,” writes Cusick.

MIT researchers have found that in the U.S., “fires started by people account for a majority of premature deaths related to inhalation of tiny smoke particles,” writes Cara Murez for U.S. News & World Report. “Fires not only threaten human lives, infrastructure and ecosystems, but they are also a major cause for concern in terms of air quality,” says Therese Carter PhD ’22.
