Architects from MIT and Generate Technologies have designed Boston’s first cross-laminated timber (CLT) building, a “’revolutionary’ type of timber [that] promises to reduce emissions that cause climate change, create affordable housing and jumpstart a new job-producing, homegrown industry in New England,” reports Bruce Gellerman and Kathleen McNerney for WBUR.
A study by Prof. Jessika Trancik examines how cheap energy storage must be for the U.S. to rely on renewable energy, reports David Roberts for Vox. The research demonstrates how “a US energy grid run entirely on renewable energy (at least 95 percent of the time), leaning primarily on energy storage to provide grid flexibility, may be more realistic, and closer to hand, than conventional wisdom has it,” writes Roberts.
WCVB-TV’s Mike Wankum visits MIT to learn about the Solar Electric Vehicle Team. “We are trying to prove that we can move away from cars that rely on gasoline or diesel,” explains undergraduate Salem Ali, “and move towards more electric vehicles, and potentially even vehicles that you don’t have to plug in.”
John Yang reports for PBS NewsHour about technologies to harvest fog to secure the world’s water supply, including one system designed by Prof. Kripa Varanasi to collect water from power plant cooling towers. Varanasi and his team “discovered that zapping air rich in fog with a beam of electrically charged particles draws the droplets toward the mesh, dramatically increasing its ability to collect water,” says Yang.
In an article for The Washington Post, Prof. Kate Brown examines the impacts of the Chernobyl nuclear meltdown. Brown notes that the consequences of the accident reached further than initially thought, writing that “the fallout map shows that Chernobyl radioactivity drifted widely across Europe, usually in areas with higher altitudes and precipitation.”
Jonathan Shieber of TechCrunch reports that Commonwealth Fusion Systems, a startup collaborating with MIT, has raised an additional $50 million toward its efforts to develop a commercial fusion reactor. “Commonwealth Fusion expects to have its smallest possible reactor built by 2025 thanks to the research that MIT has done on proprietary magnet technology that the company uses to confine its nuclear reaction,” writes Shieber.
Researchers from a number of institutions, including MIT, are exploring the feasibility of cold fusion, reports Steven Salzberg for Forbes. The researchers explained that while they were unable to successfully produce cold fusion, their exploration of this topic “is likely to have a substantial impact on future energy technologies.”
National Geographic reporter Michael Greshko writes about a new effort by researchers from a number of institutions, including MIT, to reassess the possibility of cold fusion. Prof. Yet-Ming Chiang explains that he hopes to be able to create a “‘reference experiment’ for other labs to also advance research into lower-energy nuclear physics.”
Bloomberg News reporter Carol Massar spotlights how MIT researchers have developed a robot that can identify and sort recyclables. “The system includes a soft Teflon hand that uses tactile sensors to detect the size of an object and the pressure needed to grasp it,” Massar reports. “From there it can determine if it’s made of metal, paper or plastic.”
Scientific American reporter Jeremy Hsu highlights how CSAIL researchers have developed a robot that can automatically sort recycling. The robot “uses soft Teflon ‘fingers,’ which have fingertip sensors to detect object size and stiffness,” Hsu explains.
A new MIT study suggests that “strings of plastic balls dangled in the ocean could harvest enough cobalt for hundreds of thousands of electric car batteries,” reports David Adam for New Scientist. The researchers think the system could “catch enough dissolved cobalt from seawater each year to make a battery for every Tesla Model 3 that has rolled off the production line so far,” says Adam.
Prof. Dennis Whyte, director of MIT’s Plasma Science and Fusion Center, speaks with NBC Mach reporter Dan Falk about the possibilities of fusion power. “Fusion will have one of the smallest possible environmental footprints of any power source,” says Whyte. “It will be sustainable for the foreseeable future of mankind.”
In an article for Bloomberg News, Noah Smith highlights a study by MIT researchers that examines the factors influencing the decline in solar prices. The researchers found that, “from 1980 to 2001, government-funded research and development was the main factor in bringing down costs, but from 2001 to 2012, the biggest factor was economies of scale,” Smith explains.
A new study by MIT researchers that sheds light on heat transfer in boiling water could allow nuclear power plants to run more efficiently, reports Jim Efstathiou Jr. for Bloomberg News. “Learning more about how heat is transferred could help safely boost the output from nuclear power plants by as much as 20 percent,” Efstathiou explains.
Writing for The Guardian, Prof. Kate Brown argues that a better understanding of the health ramifications of radioactivity is needed before nuclear power is expanded. “Before we enter a new nuclear age, the declassified Chernobyl health records raise questions that have been left unanswered about the impact of chronic low doses of radioactivity on human health,” writes Brown.
