Writing for The Washington Post, graduate student Thomas Roberts underscores the importance of investing in new technologies to mitigate the risks posed by space debris. “Space operators can control how some large objects return to Earth. But this requires extra fuel reserves and adaptive control technologies, which translate into higher costs,” writes Roberts.
Researchers at MIT have developed a supercapacitor, an energy storage system, using cement, water and carbon, reports Macie Parker for The Boston Globe. “Energy storage is a global problem,” says Prof. Franz-Josef Ulm. “If we want to curb the environmental footprint, we need to get serious and come up with innovative ideas to reach these goals.”
Writing for The Hill, Andre Zollinger, senior policy manager at J-PAL Global, makes the case that “current attention to air pollution can be transformational for how we tackle climate change. Policy leaders in the U.S. and abroad should seize this moment of reckoning over our common struggle for clean air as an opportunity to focus on policies that are known to curb air pollution and simultaneously combat climate change.”
Sean Hunt MS ’13 PhD ’16 co-founded Solugen, a startup working to develop industrial chemicals with environmentally friendly ingredients, reports David H. Freedman for Newsweek. “The company's goals over the next seven years are to reduce the carbon emissions released by industry into the environment by an amount equivalent to eliminating 2 million cars, and to make enough bioplastic to get rid of 5 billion non-degradable plastic bottles,” writes Freedman.
Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.
An analysis by the MIT Sloan Sustainability Initiative and Climate Interactive has found that planting a trillion trees would only prevent 0.27 degrees of warming by 2100, reports Maxine Joselow for The Washington Post. “Trees are great. I personally love to be out in the forests as much as I possibly can,” says Prof. John Sterman. “But the reality is very simple: You can plant a trillion trees, and even if they all survived, which wouldn’t happen, it just wouldn’t make that much difference to the climate.”
Fast Company reporter Adele Peters writes that MIT researchers have developed a new type of concrete that can store energy, potentially enabling roads to be transformed into EV chargers and home foundations into sources of energy. “All of a sudden, you have a material which can not only carry load, but it can also store energy,” says Prof. Franz-Josef Ulm.
MIT engineers have uncovered a new way of creating an energy supercapacitor by combining cement, carbon black and water that could one day be used to power homes or electric vehicles, reports Jeremy Hsu for New Scientist. “The materials are available for everyone all over the place, all over the world,” explains Prof. Franz-Josef Ulm. “Which means we don’t have the same restriction as with batteries.”
MIT researchers have discovered that when combined with water, carbon black and cement can produce a low-cost supercapacitor capable of storing electricity for later use, reports Andrew Paul for Popular Science. “With some further fine-tuning and experimentation, the team believes their enriched cement material could one day compose portions of buildings’ foundations, or even create wireless charging,” writes Paul.
Researchers at MIT have found that cement and carbon black can be combined with water to create a battery alternative, reports Robert Service for Science. Professor Franz-Josef Ulm and his colleagues “mixed a small percent of carbon black with cement powder and added water,” explains Service. “The water readily combines with the cement. But because the particles of carbon black repel water, they tend to clump together, forming long interconnected tendrils within the hardening cement that act like a network of wires.”
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.
Sublime Systems, a startup founded by Prof. Yet-Ming Chiang and former MIT postdoc Leah Ellis, is working to decarbonize cement making – a process which currently accounts for eight percent of global carbon emissions. “The world has a huge appetite for cement, and Sublime is working to scale its production to meet it,” writes Casey Crownhart for The Spark, MIT Technology Review’s weekly climate newsletter.
Prof. Yang Shao-Horn spoke at the State of the Art Jewelry Summit to discuss the jewelry industry’s impact on carbon emissions and sustainability efforts, reports Caroline Palmer for the Financial Times. Shao-Horn's suggestions to tackle the problem involved a mix of a carbon tax, “which could encourage the use of new technology, including electric vehicles, as well as shifting mining practices away from open site to the development of mobile mining vehicles powered by renewable energy or hydrogen,” writes Palmer.
Writing for the Financial Times, Prof. Robert Pindyck makes the case that households, private businesses and governments must "invest in adaptation to climate change, in order to counter its possible impact.” Pindyck writes, “Now is the time to put more effort into efficient CO₂ emission reduction, and invest in adaptation to limit the impacts of climate change.”
Researchers from MIT and elsewhere have found that new building codes put in place to combat climate change could impact home affordability in the greater Boston area, reports Paula Ebben for CBS Boston, “If widely adopted, [the codes] could add up to $23,000 to the cost of an average home, leaving an additional 33,000 Massachusetts residents priced out of the market,” writes Ebben.
