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.
Prof. Jessika Trancik speaks with Wall Street Journal reporter Nidhi Subbaraman about the dramatic drops in costs to manufacture and sell renewable technologies. Subbaraman notes that Trancik’s research shows that “the steep drop in solar and lithium-ion battery technology was enabled by market expansion policies as well as investment in research and development by governments and the private sector.”
The MIT AI Hardware Program seeks to bring together researchers from academia and industry to “examine each step of designing and manufacturing the hardware behind AI-powered technologies,” reports Emily Bamforth for EdScoop. “This program is about accelerating the development of new hardware to implement AI algorithms so we can do justice to the capabilities that computer scientists are developing,” explains Prof. Jesús del Alamo.
The MIT AI Hardware Program is aimed at bringing together academia and industry to develop energy-optimized machine-learning and quantum-computing systems, reports Katyanna Quach for The Register. “As progress in algorithms and data sets continues at a brisk pace, hardware must keep up or the promise of AI will not be realized,” explains Professor Jesús del Alamo. “That is why it is critically important that research takes place on AI hardware."
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.”
Research engineer Paul Woskov speaks with Bloomberg Radio host Tom Moroney and Joe Shortsleeve about his work with Quaise Energy in developing a laser to drill holes into the earth. “There is a lot of heat contained within our planet. The amount of heat that is present, if tapped, could supply all of our energy needs for several million years,” says Woskov.
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.”
Researchers from MIT and MIT spinoff Quaise Energy speak with Boston Globe reporter David Abel about their work developing a new way to drill as deep as 12 miles into the Earth’s crust, using a special laser, which could provide a way to tap the geothermal energy in the rocks. “This is game-changing,” Woskov said. “We now have the potential to exploit an energy source that . . . could unleash the virtually limitless supply of energy beneath our feet.”
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.”
Boston Globe reporter Hiawatha Bray spotlights how a number of MIT spinoffs are working on changing the world’s energy-storage systems. “Behind these companies are key technological advances in chemistry and materials, many of them pioneered at the Massachusetts Institute of Technology,” writes Bray. “These breakthroughs have put battery startups at the forefront of the region’s climate-tech sector.”
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.
Prof. Yet-Ming Chiang and his colleagues are developing a new, inexpensive iron-air battery technology that could provide multi-day storage for renewable energy by 2024 through their startup Form Energy, reports Anuradha Varanasi for Popular Science. Chiang explains that “the battery can deliver clean electricity for 100 hours at a price of only $20 kilowatts per hour – a bargain compared to lithium-ion batteries, which cost up to $200/kWh,” writes Varanasi.
New Scientist reporter Chen Ly writes that MIT researchers have developed a new technique that uses static electricity to remove the dust from solar panels, which could save around 45 billion liters of water annually. “I think water is a precious commodity that is very undervalued,” says Prof. Kripa Varanasi. “What I’m hoping is this will spur more people to think about water issues.”
