Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry.
Susy Jones, a sustainability project manager for MIT’s Office of Sustainability advises WBUR reporter Andrea Shea through her decision to eat 100% local foods for one week. “Making decision when you’re stressed is really difficult and that’s why I think it’s hard for anyone to eat healthy or local,” says Jones. “That’s why people at the end of the day end up getting fast food. So, we have to reduce the barriers for purchasing healthy local food.”
MIT President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry discussed the urgency of addressing climate change during the Climate Grand Challenges Showcase event, reports Chris Lisinski for the State House News Service. “Climate change has been called a ‘super wicked’ problem. In Boston, that might sound like a local way of saying ‘really hard,’ but this phrase is actually a technical term,” Reif said. “It describes any enormously complex societal problem that has no single right answer and no clear finish line as well as multiple stakeholders with conflicting priorities and no central authority empowered to solve it.”
Bloomberg News reporter Janet Wu speaks with President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry during the Institute’s Climate Grand Challenges showcase event. “If you can capture the emissions -- literally, genuinely -- then you’re reducing the problem,” said Kerry of the importance of eliminating greenhouse gas emissions.
Prof. Jessika Trancik speaks with ABC News about the urgent need to transition to renewable energy sources, and how we can build a future powered by alternative energy. “Up until recently there were really significant questions about whether we could transition to another [energy] foundation,” says Trancik. “This question has now been answered in that we now have cost competitive renewable primary energy in the form of solar and wind energy and also in other types of renewable energy.”
A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.
MIT announced five projects "targeting the world's toughest climate riddles" that were selected following a rigorous two-year competition, reports Benjamin Kail for Boston Business Journal. “Climate Grand Challenges represents a whole-of-MIT drive to develop game-changing advances to confront the escalating climate crisis, in time to make a difference,” says President L. Rafael Reif.
Using cellulose nanocrystals found in trees, MIT researchers have developed a new material that is both tough and strong, reports Kathryn Hulick for Science News for Students. Abhinav Rao PhD ’18 explains that he was inspired to create the material “by looking at what nature has to teach us.”
Mashable reporter Emmett Smith spotlights how MIT researchers have developed a new technique to clear dust from solar panels without using water. The new method uses “electrostatic repulsion, where an electrode that glides above the panel electrically charges dust particles and subsequently repels them.”
Cary Lin MBA ’16 co-founded Common Heir, a clean and plastic-free beauty company dedicated to creating “a high-impact line of skincare that had a low impact on the environment,” reports Geri Stengel for Forbes.
MIT engineers have developed a new contactless method to clean solar panels that could save billions of gallons of water, reports Anuradha Varanasi for Popular Science. “I was amazed at the sheer amount of pure water that is required for cleaning solar panels,” says Prof. Kripa Varanasi. “The water footprint of the solar industry is only going to grow in the future. We need to figure out how to make solar farms more sustainable.”
Daily Beast reporter Miriam Fauzia writes that MIT researchers have developed a new way to create carbon fibers that are stronger and lighter than steel, using leftover waste from crude oil processing. “The new findings could usher in an age of heavy-duty cars that consume less fuel thanks to their decreased weight,” writes Fauzia.
Hill reporters Saul Elbein and Sharon Udasin spotlight how MIT researchers have developed a way to make lightweight fibers for possible use in the bodies of cars out of the waste material from the refining of petroleum. “The ‘heavy, gloppy’ leftovers from the petroleum refining process could become a key ingredient in making electric vehicles lighter, less expensive and more efficient,” they write.
Prof. Kripa Varanasi, graduate student Sreedath Panath, and a team of researchers are developing a water-free way to clear dust off of solar panels, reports Billy Hurley and Ed Brown for Tech Briefs. “Water is such a precious commodity, and people need to be careful about how to make use of this resource that we have,” says Varanasi. “The solar industry really needs to keep this in mind; we don’t want to be solving one problem and creating another.”
MIT researchers have developed a new water-free system that uses static electricity to clear dust from solar panels, reports Miriam Fauzia for The Daily Beast. “By using this technique, we can recover up to 95 percent of a solar panel’s power output,” explains graduate student Sreedath Panat.
