Boston Globe reporter Jon Chesto spotlights the fall fair event held as part of the MIT x GE Vernova Energy & Climate Alliance, during which, GE Vernova CEO Scott Strazik shared his enthusiasm for hiring MIT graduates. “Something we talk a lot about inside Vernova is the world is changing very quickly but we need to change quicker and even faster than that so we can lead in the world,” says Strazik. “Over the last year-plus on this campus, we see a lot of opportunities for us to get better through bringing you into the organization.”  

MIT startup Alsym Energy, cofounded by Prof. Kripa Varanasi, has developed an alternative to lithium-ion batteries using sodium ions, writes Morgan Clendaniel for Fast Company. “The battery is nonflammable and nontoxic, allowing it to be placed in more sensitive areas and saving money on cooling systems that often have to be co-installed with large lithium batteries,” explains Clendaniel.  

Joe Romm ‘82, PhD ‘87, “a physicist by training who became one of the most influential voices in the debate over climate change and how to stop it, using his blog to provide deep-dive insights and sharp-elbowed critiques,” died on Sept. 14, reports Clay Risen for The New York Times. “There’s nobody else like Joe Romm,” says Michael Mann, Romm’s colleague at the Penn Center. “There’s nobody else who brought all of these interlocking talents and proclivities together in the way that he did. That gave him such a unique voice, and it’s a voice that we sorely could use today.” 

BBC News reporter Chris Baraniuk highlights MIT startup Alsym Energy, which is developing sodium-ion batteries. Drew Buckley, chief executive at ESS Tech, “points out that sodium ion batteries could help distribute renewable energy to data centers,” writes Baraniuk. “And those batteries should be cheaper to run than lithium-ion alternatives, since they are not expected to require as much cooling.”  

Using AI, satellite, and ocean current data, MIT spinout Coastal Assembly constructs artificial reefs designed to help rebuild beaches restore shrinking beaches, writes Fast Company’s Adele Peters. “We take 10 years of data, and we say, where do we predict the critical areas of erosion will be in the coming months to year,” says Prof. Skylar Tibbits, co-founder of Coastal Assembly. “That tells me where the best place is to intervene—what’s the part that is most critical, where we should focus our time, effort, and money.” 

New York Times reporter Quinn Glabicki highlights Coastal Assembly, an MIT spinout that uses AI, satellite and ocean current data to monitor communities threatened by coastal erosion and create underwater structures to regrow beaches at nearly 900 coastal sites. “We can go to any community around the world and understand what has happened and then propose a solution that is very precisely tailored to them,” says Prof. Skylar Tibbits, one of Coastal Assembly’s founders.  

Prof. John Fernández joins Edgar B. Herwick, host of GBH’s “The Curiosity Desk,” to discuss Singapore’s success creating sustainable infrastructure, from having two thirds of buildings in Singapore certified green to constructing covered walkways for public spaces, and enhancing biodiversity in the city. “They have been, for many decades, very intent on being a resource efficient country,” says Fernández. “These incremental improvements go a long way towards reducing energy consumption and emissions.”  

Prof. Susan Solomon joins Cleo Abram’s “HUGE* If True,” to discuss her 1985 research uncovering how chlorofluorocarbons, were depleting the ozone layer, which led to the Montreal Protocol that banned the use of those chemicals. “It was an interesting feeling being under the ozone hole, knowing that half a world away an incredible change [the Montreal Protocol] had just occurred that really had a lot of potential to change things in the future—and indeed it did,” says Solomon.  

The Financial Times’ Anjana Ahuja spotlights research led by Prof. Dennis Whyte on the economics of fusion energy. “Economic Q, the metric devised by Whyte and others and which must exceed one to represent net economic gain, compares the capital gained over a fusion energy plant’s lifetime to that expended,” writes Ahuja. “Factors reflect the extreme engineering involved and include construction costs, component durability and the efficiency of converting fusion power into a commodity.” 

Assil Halimi PhD ‘25 speaks to TechCrunch’s Tim De Chant about his company Apollo Atomics, which is shrinking the steam generator component of a reactor to streamline nuclear power. “We don’t want to be incremental in nuclear and just improve a small thing,” says Halimi. “Our target is to beat natural gas.” 

In an opinion piece for Fast Company, Hala Hanna, Executive Director of MIT Solve, outlines a blueprint for solving the world’s hardest problems in the next decade. “The last decade rewarded whoever could invent the best solution. The next one will belong to whoever can build the conditions for good solutions to survive, spread, and rewire the systems around them,” writes Hanna.  

Prof. Danielle Wood speaks to the Scientific American’s Tom Metcalfe about how the current models of space travel, that have created trash and debris in Earth’s atmosphere and orbit, are unsustainable. “Sustainability in space means that we are able to leave to future generations something like the natural state of the Earth, the moon and the solar system,” says Wood. 

MIT researchers have developed a framework to determine what is needed to make fusion energy commercially viable, writes World Nuclear News (WNN). “The parameters in the framework describe engineering features of the fusion power plant such as power density, the efficiency of converting fusion power into an economic product, and the durability of components used in the energy conversion, in addition to costing and market parameters that assess the expenses and returns from invested capital,” explains WNN.  

Prof. Dennis Whyte and Prof. Andrew Lo have built a framework to mitigate the economic challenges of fusion power, writes Interesting Engineering’s Ameya Paleja. “While there are multiple approaches to building a nuclear fusion facility, Whyte and colleagues believe that at the end of the day, the facility should be in a position to generate more money that has gone in to building and operating it, otherwise it won’t last for long,” writes Paleja.
