A study by MIT researchers finds “using scrubbers to treat exhaust from heavy fuel oil may offer environmental performance on par with, and in some areas superior to, burning low-sulfur fuels in maritime shipping,” reports Hassan Ahmed for Engineeringness. “The research provides data that could help policymakers and industry leaders better assess the comparative costs and benefits of available fuel options,” explains Ahmed.
Graduate student Will Parker joins USA Today’s The Excerpt host Dana Taylor to discuss his research on the impact of climate change on space satellites. “We're seeing a cooling effect in the upper atmosphere where most of our satellites are operating, and because of that cooling effect, we're seeing that the entire atmosphere is contracting, so it's retreating away from low Earth orbit where we rely on that atmosphere for drag on our satellites,” explains Parker. “The effect of that retreat, that shrinking of the atmosphere, is that it's not doing as good a job at cleaning out low Earth orbit, and again, we rely on that cleaning force because we have no other way to remove most of this debris.”
Anantha Chandrakasan, MIT’s chief innovation and strategy officer and dean of MIT’s School of Engineering, speaks with Boston Globe reporter Jon Chesto about the new MIT-GE Vernova Energy and Climate Alliance. “A great amount of innovation happens in academia. We have a longer view into the future,” says Chandrakasan. He adds that while companies like GE Vernova have “the ability to get products out quickly to scale up, to manufacture, we have the ability to think past the short-term. ... It’s super smart of them to surround themselves with this incredible talent in academia. That will allow us to make the kind of breakthroughs that will keep U.S. competitiveness at its peak.”
Chronicle visits Prof. Skylar Tibbits and the Self-Assembly Lab to see how they are embedding intelligence into the materials around us, including furniture, clothing and buildings. Prof. Caitlin Mueller and graduate student Sandy Curth are digging into eco-friendly construction with programmable mud by “taking a low-cost material and a really fast manufacturing system to make buildings out of very, very low climate impact materials.” Says Tibbits: “MIT is a really wild place, and most people know of it for its technical expertise…But what I am really inspired by is on the creative end, the design spectrum. I think the mix of those two is super special.” He adds: “We can ask the right questions and discover new science, and we can also solve the right problems through engineering.”
E&E News reporter Christa Marshall writes that the new MIT-GE Vernova Energy and Climate Alliance will “scale sustainable energy systems across the globe” and advance breakthrough low-carbon technologies.
MIT engineers have developed a new system that helps pesticides adhere more effectively to plant leaves, allowing farmers to use fewer chemicals without sacrificing crop protection, reports Michigan Farm News. The new technology “adds a thin coating around droplets as they are being sprayed onto a field, increasing the stickiness of pesticides by as much as a hundredfold.”
“A breakthrough from MIT researchers and AgZen, a spinoff company, is making agricultural spraying more efficient—cutting pesticide waste, lowering costs, and reducing environmental impact,” reports Rural Radio Network. “The technology works with existing sprayers, eliminating the need for costly equipment changes. In field tests, it doubled product retention on crops like soybeans and kale. AgZen’s spray-monitoring system, RealCoverage, has already helped farmers reduce pesticide use by 30 to 50 percent, and the new coating could improve efficiency even further.”
Researchers at MIT have discovered how “greenhouse gases are impacting Earth’s upper atmosphere and, in turn, the objects orbiting within it,” reports Grace Snelling for Fast Company. “If we don’t take action to be more responsible for operating our satellites, the impact is that there are going to be entire regions of low Earth orbit that could become uninhabitable for a satellite,” says graduate student William Parker.
MIT researchers have discovered that increased greenhouse gas emissions in the Earth’s upper atmosphere can “potentially cause catastrophic satellite collision in low-Earth orbit,” reports Bruce Dorminey for Forbes. “When the thermosphere contracts, the decreasing density reduces atmospheric drag — a force that pulls old satellites and other debris down to altitudes where they will encounter air molecules and burn up,” Dorminey explains. “Less drag therefore means extended lifetimes for space junk, which will litter sought-after regions for decades and increase the potential for collisions in orbit.”
MIT researchers have found that high levels of greenhouse gas emissions in the atmosphere may increase the risk of satellite collisions, reports Sachi Kitajima Mulkey for Grist. “The environment is very cluttered already. Satellites are constantly dodging right and left,” says graduate student William Parker. “As long as we are emitting greenhouse gases, we are increasing the probability that we see more collision events between objects in space.”
Associated Press reporter Seth Borenstein writes that MIT scientists have found that climate change could “reduce the available space for satellites in low Earth orbit by anywhere from one-third to 82% by the end of the century, depending on how much carbon pollution is spewed.” Graduate student William Parker explains: “We rely on the atmosphere to clean up our debris. There’s no other way to remove debris. It’s trash. It’s garbage. And there are millions of pieces of it.”
A new study by MIT researchers finds that “climate change could threaten the future use of satellites and significantly reduce the number of spacecraft that can safety orbit Earth,” reports Julia Jacobo for ABC News. The researchers found “global warming is causing space debris to linger above the planet for longer periods of time, leaving less space for functioning satellites and posing a growing problem for the long-term use of Earth’s orbital space,” Jacobo explains. “Reducing greenhouse gas emissions doesn't just help us on Earth, it also has the potential to protect us from long-term sustainability issues in space,” explains graduate student William Parker.
A study by MIT scientists has found that increased greenhouse gas emissions will shrink the Earth’s upper atmosphere causing a “drop in the satellite-carrying capacity of low Earth orbit,” repots Passant Rabie for Gizmodo. “Without an atmosphere, most space debris would remain in orbit indefinitely,” Parker said. “As the atmosphere thins, debris lingers longer, increasing the risk to active satellites. With the growing consequences of space debris, we can accommodate fewer debris-generating events.”
Researchers at MIT have found that climate change could raise the risk of satellite collisions, reports Justine Calma for The Verge. “We’ve really reached the end of that era of ‘space is big,’ and I think we should stop saying that,” says graduate student, William Parker. “People don’t realize that the space sustainability issue is really an issue that impacts them directly.”
David Zipper, a senior fellow at the Mobility Initiative, speaks with WBUR Here & Now co-host Scott Tong about “car bloat,” the trend of increasingly large SUVs and trucks on the road. “I personally believe that car bloat is a major public health issue, it's a major policy issue, but I'll be candid, I don't think the average American does right now,” explains Zipper. “We need people to understand it and appreciate it. And in my view, that's going to need to happen at the grassroots level before we can expect really anybody in Washington to address this problem in the way that it deserves to be addressed.”
