In an article he co-authored for Fortune, postdoctoral associate Matthew Hughes explains how extreme heat affects different kinds of machines. “In general, the electronics contained in devices like cellphones, personal computers and data centers consist of many kinds of materials that all respond differently to temperature changes,” they write. “So as the temperature increases, different kinds of materials deform differently, potentially leading to premature wear and failure."
Prof. Tracy Slatyer and Prof. Janet Conrad speak with Scientific American reporter Clara Moskowitz about their favorite discoveries in the field of physics. Slatyer notes that “the accelerating expansion of the universe has to be a strong contender.” For Conrad, “I think my favorite event in physics was the prediction of the existence of the neutrino [a subatomic particle with no charge and very little mass] because so much of our fundamental approach to physics today grew out of that moment.”
In this video for Wired, Prof. Anne White explains the nature of nuclear fusion in five levels of increasing difficulty to a child, a teen, a college student, a grad student, and an expert. “Fusion is so exciting because it is extraordinarily beautiful physics, which underpins some of the most basic processes in our universe," says White. “Nuclear processes have a tremendously valuable application for humankind, a virtually limitless, clean, safe, carbon-free form of energy.”
Researchers from MIT’s Plasma Science and Fusion Center and Commonwealth Fusion Systems (CFS) are using high-temperature superconducting tape as a key part of the design for their tokamak reactor, reports Tom Clynes for IEEE Spectrum. The researchers believe that “this novel approach will allow it to build a high-performance tokamak that is much smaller and less expensive than would be possible with previous approaches,” Clynes notes.
Jacob DeWitte SM ’11, PhD ’14 co-founded Oklo, a startup working toward developing small nuclear power plants to deliver emission-free, reliable, and affordable power, reports Heather Wishart-Smith for Forbes.
Commonwealth Fusion Systems, MIT’s Plasma Science and Fusion Center and others are working to build SPARC, a prototype device that aims to extract net energy from plasma and generate fusion power, reports Philip Ball for Scientific American. “SPARC will be a midsize tokamak in which the plasma is tightly confined by very intense magnetic fields produced by new high-temperature superconducting magnets developed at MIT and unveiled in 2021.”
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 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.”
MIT researchers have developed a new machine learning model that can identify and track blobs of plasma created in controlled nuclear-fusion research, reports Ed Browne for Newsweek. “Fusion research is a complex, multidisciplinary project that requires technologies from many fields,” explains graduate student Woonghee “Harry” Han.
In a cartoon for The Boston Globe, Sage Stossel highlights research underway at the MIT Plasma Science and Fusion Center, where scientists are working on developing the future of fusion energy.
MIT researchers have developed a new hardware that offers faster computation for artificial intelligence with less energy, reports Kyle Wiggers for TechCrunch. “The researchers’ processor uses ‘protonic programmable resistors’ arranged in an array to ‘learn’ skills” explains Wiggers.
Nuclear science experts say that the potential shut down of Zaporizhzhia Nuclear Power Plant (ZNPP) in Ukraine can lead to energy implications and climate change, reports Anna Skinner for Newsweek. "The Earth is heating up, and we don't have any way to stop it right now except to stop putting more greenhouse gases into the atmosphere," says Prof. Michael Golay. "The nice thing about nuclear is it doesn't emit much in the way of greenhouse gases."
A new proposed economic bill could provide “game-changing” incentives for the nuclear energy industry, reports Jennifer McDermott and Mary Katherine Wildeman for the Associated Press. The bill “is really substantial,” says Prof. Jacopo Buongiorno. “This should move the needle in terms of making these technologies economically viable right off the bat.”
