MIT researchers have developed a new hardware that offers faster computation for artificial intelligence with less energy, reports Kyle Wiggers for TechCrunch. “The researchers’ processor uses ‘protonic programmable resistors’ arranged in an array to ‘learn’ skills” explains Wiggers.
Researchers at MIT have developed a battery that uses aluminum and sulfur, two inexpensive and abundant materials, reports Alex Knapp and Alan Ohnsman for Forbes. “The batteries could be used for a variety of applications,” write Knapp and Ohnsman.
MIT researchers have created a new battery using inexpensive and plentiful materials to store and provide power, reports Tony Ho Tran for The Daily Beast. “The study’s authors believe that the battery can be used to support existing green energy systems such as solar or wind power for times when the sun isn’t shining or the air is still,” writes Tran.
Prof. Donald Sadoway and his colleagues have developed a battery that can charge to full capacity in less than one minute, store energy at similar densities to lithium-ion batteries and isn’t prone to catching on fire, reports Alex Wilkins for New Scientist. “Although the battery operates at the comparatively high temperature of 110°C (230°F),” writes Wilkins, “it is resistant to fire because it uses an inorganic salt that can’t burn as its electrolyte, the material that allows charge to flow inside a battery.” Sadoway explains that “this is a totally new battery chemistry."
MIT scientists have discovered a new method to maximize wind farm output, reports Gwen Egan for Boston.com. “While there are pros and cons to this strategy, it’s possible that it could allow for smaller wind farms that take up less land to produce more energy,” says Prof. Michael Howland. “It’s critically important we do this now, as we embark on building much more offshore wind. We need to ensure that our future wind farms maximize efficiency to increase the pace of decarbonization.”
MIT scientists have found that changing the angle of turbine blades on wind farms could increase energy output, reports David Abel for The Boston Globe. “Given the scale of wind deployment needed to achieve state and federal climate goals, we need optimal wind farm performance to ensure efficient, rapid decarbonization,” says Prof. Michael Howland. “Our method resulted in significant energy gains over standard industry operations, and, importantly, it can be instituted with minimal cost.”
Gradiant, an MIT startup founded by Anurag Bajpayee PhD ’12, S.M. ‘08 and Prakash Govindan PhD ’12, has developed an energy efficient system that purifies water by mimicking natural rainfall cycles, reports Aaron Pressman for The Boston Globe. “Nature has the advantage of having all the surface area of the oceans available freely and a free source of energy from the sun,” Govindan said. “We have to engineer this into a compact, highly efficient, and energy-efficient industrial device.”
Prof. Christopher Knittel speaks with Andy Uhler of Marketplace about gasoline process and the crack spread, the difference between the cost of oil and the cost to refine it. “Increases in the crack spread that we’ve seen recently has been just supply and demand,” said Knittel.
Postdoctoral researcher Murat Onen and his colleagues have created “a nanoscale resistor that transmits protons from one terminal to another,” reports Alex Wilkins for New Scientist. “The resistor uses powerful electric fields to transport protons at very high speeds without damaging or breaking the resistor itself, a problem previous solid-state proton resistors had suffered from,” explains Wilkins.
Commonwealth Fusion Systems (CFS), an MIT spinout, has signed an agreement with the U.K. Atomic Energy Authority (UKAEA) to “support the fastest path to clean commercial fusion energy,” reports Ed Browne for Newsweek. “CFS says its agreement with UKAEA could involve exchanges of knowledge and collaboration on things like fuel, modeling, manufacturing and maintenance,” writes Browne.
Postdoctoral fellow Joshua A. Schwartz and University of Pennsylvania PhD candidate Sabrina B. Arias write for The Washington Post about their research exploring how American cities and towns are taking action to help reduce carbon emissions. “Major urban areas account for about 30 percent of the U.S. carbon footprint,” they write. “This means even relatively narrow efforts focused on those cities could still have a significant impact.”
Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.”
Writing for The Boston Globe, Prof. Ernest Moniz, former secretary of energy, makes the case for addressing climate change and energy insecurity collectively. “US decision makers in the public and private sector need to implement data-driven plans that reflect real needs and enable a credible and sustained energy transition to zero-carbon energy in the mid-century time frame,” writes Moniz.
TechCrunch reporter Devin Coldewey writes that a new report by MIT researchers finds that in order to successfully transition to a renewable energy grid, the federal government must intervene to help build green energy storage at a scale that will meet the nation’s needs. “The federal government has the means both to subsidize the utilization of existing storage options and to fund intensive research into new and promising ones,” writes Coldewey of the report’s findings.
Ambri, an MIT startup that has developed a liquid-metal battery that can be used for grid-level storage of renewable energy, has announced that it is months away from delivering its first battery to a customer, reports Jacob Wycoff for CBS Boston. "We want to have a battery that can draw from the sun even when the sun doesn't shine," said Prof. Donald Sadoway of the inspiration for Ambri’s battery.
