Using statistical modeling, MIT researchers have found that the energy needed to power a fleet of fully autonomous EVs could generate as much carbon emissions as all the world’s data centers combined, reports Andrew Paul for Popular Science.
Washington Post reporter Pranshu Verma writes that a new study by MIT researchers finds the “future energy required to run just the computers on a global fleet of autonomous vehicles could generate as much greenhouse gas emissions as all the data centers in the world today.”
Writing for Scientific American, John Fialka spotlights Form Energy, an MIT spinout designing an iron-air battery that “could help decarbonize the nation’s power sector more cheaply than lithium-ion storage systems.” Fialka explains that “unlike current lithium-ion batteries that require expensive materials mostly from other countries such as lithium, cobalt, nickel and graphite, the proposed battery stores electricity using widely available iron metal.”
Prof. Kripa Varanasi and Vishnu Jayaprakash PhD ’21, MS ’19 have launched AgZen, a company that is trying to reduce pesticide use through the development of additives that allow more pesticide droplets to stick to plants, reports Ian Mount for Fortune. “Globally, farms are spending about $60 billion a year on these pesticides, and our goal is to try to get them to cut that down while still not compromising on pest control,” says Jayaprakash.
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. 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.”
Prof. Dennis Whyte, director of MIT’s Plasma Science and Fusion Center, discusses the significance of nuclear fusion energy with Boston Globe reporter David Abel following news that an advance had been made in the development of nuclear fusion. “It’s very exciting, but we’re not all the way there,” Whyte said. “I will be really excited when we put the first watts on the grid.”
Prof. Dennis Whyte, director of MIT’s Plasma Science and Fusion Center, speaks with USA Today about the promise and challenges posed by nuclear fusion energy, in light of an announcement that scientists have crossed a milestone in their efforts to develop fusion energy. Whyte explains that, in theory, fusion could "replace all carbon-based energy sources, because it's scalable in a way that means it can actually power civilization.”
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.
Alumna Geeta Sankappanavar founded Akira Impact, an investment firm that directs capital to support the UN Sustainable Development Goals, reports Cheryl Robinson for Forbes. “The firm invests in companies that support gender equality, clean water and sanitation, clean energy and responsible consumption and production,” writes Robinson.
