Researchers at MIT have developed a “new type of transistor using semiconductor nanowires made up of gallium antimonide and iridium arsenide,” reports Alex Knapp for Forbes. “The transistors were designed to take advantage of a property called quantum tunneling to move electricity through transistors,” explains Knapp.
Writing for MarketWatch, Joseph Coughlin, director of the MIT AgeLab, examines how the revival of nuclear power could be beneficial for older workers with expertise in the industry. “The myth of older workers taking up space must end in every industry, but in a high-stakes sector such as nuclear power, older workers aren’t taking up space — they are a critical part of the future," writes Coughlin.
Prof. Christopher Reinhart speaks with GBH reporter Craig LeMoult about the feasibility of harvesting energy from the Charles River. Reinhart notes that using renewable heat pumps along with the old, existing steam infrastructure could be a good option for Boston and other cities around the country that have district energy systems. “I think you would see a lot of those, especially with the overall push towards decarbonization,” says Reinhart.
Prof. Jacopo Buongiorno speaks with Nature reporter Davide Castelvecchi about how AI has increased energy demand and the future of nuclear energy.
Fast Company reporter Kristin Toussaint spotlights a new study by MIT researchers that examines the energy burden in the U.S., the percent of a household’s income spent on energy costs. The researchers found a disproportionate number of people in the South experiencing energy poverty. “As the climate warms, we’re going to need to use more and more energy on air-conditioning, and that’s going to increase the burden on low-income households,” explains Prof. Christopher Knittel.
Prof. Jessika Trancik speaks with BBC reporter Isabelle Gerretsen about the future of electric vehicles and how shifting to EVs can help reduce carbon emissions. Trancik and her research lab developed an online tool, dubbed Carboncounter, that can analyze the climate impact of different vehicles. “A shift to an electric vehicle is one of the single most impactful decisions that someone can make if they want to reduce their own emissions," explains Trancik.
Writing for The Washington Post, Prof. Daniela Rus, director of CSAIL, and Nico Enriquez, a graduate student at Stanford, make the case that the United States should not only be building more efficient AI software and better computer chips, but also creating “interstate-type corridors to transmit sufficient, reliable power to our data centers.” They emphasize: “The United States has the talent, investor base, corporations and research institutions to write the most advanced AI models. But without a powerful data highway system, our great technology advances will be confined to back roads.”
Graduate student Zoe Fisher speaks with Yusuf Khan of The Wall Street Journal’s about what inspired her to pursue a career in nuclear engineering, noting that being able to fight climate change firsthand is one of the key reasons she wanted to make a career in nuclear.. “It’s a cool thing to study that is going to have a lot of broader impacts,” Fisher says.
Prof. Asegun Henry has been named a 2024 Grist honoree for his work developing a “sun in a box,” a new cost-effective system for storing renewable energy, reports Grist. Based on his research, Prof. Henry has founded Fourth Power, a startup working to build a prototype system that will hopefully “allow us to decarbonize electricity,” says Henry.
Prof. Michael Strano joins “Somewhere on Earth” podcast host Gareth Mitchell to discuss how he and his colleagues developed tiny batteries that could be used to power cell-sized robots. Roughly the thickness of a human hair, the new battery can create a current by capturing oxygen. “I would say we're making the LEGOs, the building blocks that go into robots,” Strano says. “We’re building the parts and it's an exciting time for the field.”
Anurag Bajpayee MS '08, PhD '12 and Prakash Govindan PhD '12 founded Gradiant, an MIT startup “trying to reduce both costs and energy while eliminating chemicals” in water, reports Diana Olick for CNBC. “We take highly contaminated wastewater which contains solvents, which contains dissolved salt, which contains organics, and we eliminate the entire liquid waste,” says Govindan.
Writing for Foreign Affairs, MIT Innovation Fellow Brian Deese proposes a Clean Energy Marshall Plan to combat climate change and renew U.S. leadership on a global stage, arguing this can be done in a way that promotes U.S. interests and supports aligned countries. “In this moment of domestic economic strength—stark against the backdrop of heightened competition, a fracturing world, and a raging climate crisis—the United States can do something generous for people across the globe in a way that benefits Americans,” writes Deese. “It should take that leap, not just because it is the morally right thing to do but also because it is the strategically necessary thing to do.”
Researchers at MIT have developed tiny batteries capable of powering cell-sized robots that can “execute tasks as varied as targeting drug delivery inside the human body to checking pipelines for gas leaks,” reports Brian Heater for TechCrunch. “Despite the barely visible size, the researchers say the batteries can generate up to 1 volt, which can be used to power a sensor, circuit or even a moving actuator.”
Research affiliate Thomas Neff, a physicist known for his proposal aimed at “reducing the global stockpile of nuclear weapons and helping stabilize the former Soviet Union,” has died at age 80, reports Harrison Smith for the Washington Post. Credited with the “Megatons to Megawatts” agreement, “Dr. Neff spent years working in arms control, nuclear weapons proliferation and uranium markets, bridging the divide between experts who specialized in the kind of highly enriched uranium used for warheads and the far less enriched version used for electricity generation,” Smith writes.
Research affiliate Thomas Neff, a physicist whose work with nuclear weapon conversion led to an agreement “that reduced nuclear threats and produced one of the greatest peace dividends of all time,” has died at the age of 80, reports William J. Broad for The New York Times. Neff’s idea of converting Soviet nuclear weapons into electricity used to power American cities “turned some 20,000 Russian nuclear arms into electricity, lighting billions of American lightbulbs.”
