MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.
Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”
In an article about how researchers are exploring why ancient Roman and Mayan buildings are still standing, AP reporter Maddie Burakoff highlights how researchers from MIT found that an ancient Roman technique for manufacturing concrete gave the material “self-healing” properties. “We don’t need to make things last quite as long as the Romans did to have an impact,” says Prof. Admir Masic. “If we add 50 or 100 years to concrete’s lifespan, “we will require less demolition, less maintenance and less material in the long run.”
Dan Stack PhD ’20 speaks with TechCrunch reporter Tim De Chant about his startup Electrified Thermal Solutions, which is developing electrified firebricks to help decarbonize building materials.
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.”
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.
MIT Innovation Fellow Brian Deese speaks with CNBC host Andrew Ross Sorkin about the state of the U.S. economy and the impact of “Bidenomics,” President Joe Biden’s economic philosophy.
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.”
MIT researchers have developed a new compact, lightweight design for a 1-megawatt electrical motor that “could open the door to electrifying much larger aircraft,” reports Ed Gent for IEEE Spectrum. “The majority of CO2 is produced by twin and single-aisle aircraft which require large amounts of power and onboard energy, thus megawatt-class electrical machines are needed to power commercial airliners,” says Prof. Zoltán Spakovszky. “Realizing such machines at 1 MW is a key stepping stone to larger machines and power levels.”
Lisa Dyson PhD ‘04 founded Air Protein, a company looking to “bring recycled carbon cultivated into food with the taste and texture of chicken, meat, and seafood,” reports Geri Stengel for Forbes.
Financial Times reporter Simon Mundy and Kaori Yoshida spotlight Gradiant, an MIT startup that has developed new methods of handling industrial wastewater. “Gradiant promises customers that its technology will allow them to purify and reuse larger amounts of water, reducing the amount they need to source externally,” write Mundy and Yoshia.
