WBUR reporter Daniel Ackerman spotlights Sublime Systems, an MIT startup working to develop “construction-ready, emissions-free cement.” Ackerman explains that: “Sublime’s new approach uses electricity instead of heat. That means the process can be powered with renewable energy rather than fossil fuels. The method also prevents carbon dioxide from escaping the carbon-rich limestone during combustion.”
Insider reporter Katie Hawkinson explores how MIT researchers developed a new solar-powered desalination system that can remove the salt from seawater for less than the cost of U.S. tap water. Creating a device that relies on solar power, “eliminates a major financial barrier, especially for low-income countries experiencing water scarcity,” Hawkinson explains.
MIT researchers have developed a new desalination system that uses solar energy to convert seawater into drinkable water, reports Tony Ho Tran for the Daily Beast. The device could make it possible to, “make freshwater that’s even more affordable than the water coming from Americans’ kitchen faucets.”
The Hill reporter Sharon Udasin writes that MIT researchers have developed a new solar-powered desalination device that “could last several years and generate water at a rate and price that is less expensive than tap water.” The researchers estimated that “if their model was scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour,” writes Udasin.
MIT researchers have developed a new underwater system that could enable long-range and low-power underwater communication, reports Edd Gent for IEEE Spectrum. “The reason why this is really exciting is because now you start opening up many of the coastal monitoring applications,” says Prof. Fadel Adib. “It’s a turning point from this being a technology that is intellectually super interesting that we hope will work, to saying we know that this works and we have a path to deployment.”
Prof. Jessika Trancik speaks with Boston Globe reporter Aruni Soni about her new study that finds reducing the cost of solar energy will be accelerated by improvements in soft tech. “We found that the soft technology involved in solar energy really has not changed and hasn’t improved nearly as quickly as the hardware,” says Trancik. “These soft costs, in many systems, can be 50 percent or even more of the total cost of solar electricity.”
Boston Globe reporter Hiawatha Bray spotlights WiTricity, an MIT spinoff that designs wireless charging systems. “WiTricity uses magnetic fields rather than cables to give batteries a boost,” explains Bray.
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.”
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.
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.
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.”
