Prof. Steven Barrett speaks with New York Times reporter Paige McClanahan about the pressing need to make air travel more sustainable and his research exploring the impact of contrails on the planet’s temperature. “Eliminating contrails is quite a big lever on mitigating the climate impact of aviation,” said Barrett.
Bloomberg reporter Akshat Rathi spotlights Sublime Systems, an MIT startup developing new technology to produce low-carbon cement. “Sublime’s solution involves splitting the cement-making process into two steps,” explains Rathi. “The first step is to make calcium—the key element in limestone—in a form that’s ready to chemically react with silicon—the key element in sand. Sublime reduces energy use and carbon emissions in this step by avoiding limestone and using electricity, rather than coal-fired heat.”
Writing for The Boston Globe, Prof. Emeritus Ernest Moniz writes that the National Ignition Facility’s fusion energy advancement “is exciting because when the journey from science demonstration to a commercially viable power plant is completed, the electricity grid will be revolutionized.” Moniz continues, “To meet widely accepted climate objectives, we must double the clock speed of the clean energy innovation process.”
Forbes has named Commonwealth Fusion Systems one of the biggest tech innovations and breakthroughs of 2022, reports Bernard Marr. “Commonwealth Fusion Systems is now working with MIT’s Plasma Science and Fusion Center on plans to build a factory that can mass-produce components for the first commercial fusion reactors,” writes Marr.
Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the carbon impact of electric vehicles. “On average, your emissions are substantially lower if you go for the full electric [vehicle],” says Trancik. “But we could probably think of extreme edge cases where a hybrid is just as good.”
Boston Globe reporter Aaron Pressman spotlights how The Engine has “backed a number of promising climate-tech startups” and has “helped attract many other investors to climate tech.” Additionally “three-quarters of startups backed by The Engine had a founder or chief executive from an underrepresented minority group, and 44 percent had a woman in one of those roles,” Pressman notes. “From our point of view, it is unacceptable not to believe that people of very diverse backgrounds should be the next founders,” says Katie Rae, CEO and managing partner of The Engine.
Prof. Dennis Whyte, director of the Plasma Science and Fusion Center, speaks with NPR host Rob Schmitz about fusion energy and its impact on climate and energy sustainability. “So in fusion, what you're doing is literally fusing or pushing together these hydrogen atoms,” explains Whyte. “They turn into helium. This is what happens in our sun as well, too. And when that happens, that can release large amounts of net energy.”
Research Scientist Josué Velázquez Martínez speaks with Allyson Chiu from The Washington Post about how online and in-store shopping can impact the climate. “In general, anybody that is in logistics and supply chains agree that having one or two or three days more to deliver is always better,” Velázquez Martínez says. More time for deliveries makes planning, inventory replenishment and distribution “way more efficient, which in turn also reduces the amount of fuel and energy that you require to serve your customers.”
Physics World has named two research advances by MIT researchers to its list of the Top 10 Breakthroughs of the Year. Prof. Gang Chen and his colleagues were selected for their work “showing that cubic boron arsenide is one of the best semiconductors known to science.” Prof. Asegun Henry, grad student Alina LaPotin and their colleagues were nominated for “constructing a thermophotovoltaic (TPV) cell with an efficiency of more than 40%.”
Quaise Energy, an MIT spinout, is developing a millimeter wave drill to “vaporize enough rock to create the world’s deepest holes and harvest geothermal energy at scale to satisfy human energy consumption without the need for fossil fuels,” reports Tim Newcomb for Popular Mechanics.
The Verge reporter Justine Calma writes that a new study by MIT researchers finds that while wind energy has measurably improved air quality, only 32% of those benefits reached low-income communities. “The research shows that to squeeze out the greatest health benefits, wind farms need to intentionally replace coal and gas power plants,” writes Calma. “And to clean up the most polluted places — particularly those with more residents of color and low-income households — those communities need to be in focus when deploying new renewable energy projects.”
A new study by MIT researchers finds that increased usage of wind power is improving air quality in parts of the U.S., however only a third of the health benefits are being seen in disadvantaged communities, reports Alan Mozes for HealthDay. "Going forward," explains Prof. Noelle Selin, "more targeted policies are needed to reduce the disparities at the same time, for example by directly targeting [fossil fuel] sources that influence certain marginalized communities."
Increased usage of wind energy has led to health benefits, but does not affect all communities equally, reports Saul Elbein for The Hill. The researchers found that in order to increase the benefits of wind energy, “the electricity industry would have to spin down the most polluting plants at times of high wind-supply — rather than their most expensive ones,” writes Elbein.
A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”
CNN reporter Isabelle Gerretsen spotlights Lisa Dyson PhD ’04 and her startup Air Protein, which is developing a new technique to make protein “using just microbes, water, renewable energy and elements found in the air.” Air Protein has created “a new type of agriculture and a new way of growing food that doesn’t require arable land,” Dyson says.
