    Toward more efficient computing, with magnetic waves

    MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves — with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have the potential to compute far more efficiently than electronics. Classical computers rely on massive amounts of electricity for computing and data storage, […] More

    MIT Energy Initiative report charts pathways for sustainable personal transportation

    In our daily lives, we all make choices about how we travel and what type of vehicle we own or use. We consider these choices within the constraints of our current transportation system and weigh concerns including costs, convenience, and — increasingly — carbon emissions. “Insights into Future Mobility,” a multidisciplinary report released today by […] More

    Researchers generate terahertz laser with laughing gas

    Within the electromagnetic middle ground between microwaves and visible light lies terahertz radiation, and the promise of “T-ray vision.” Terahertz waves have frequencies higher than microwaves and lower than infrared and visible light. Where optical light is blocked by most materials, terahertz waves can pass straight through, similar to microwaves. If they were fashioned into […] More

    Historian of the hinterlands

    History can help us face hard truths. The places Kate Brown studies are particularly full of them.   Brown, a historian in MIT’s Program in Science, Technology, and Society, has made a career out of studying what she calls “modernist wastelands” — areas suffering after years of warfare, social conflict, and even radioactive fallout from […] More

    Helping lower-income households reap the benefits of solar energy

    Rooftop solar panels are a great way for people to invest in renewable energy while saving money on electricity. Unfortunately, the rooftop solar industry only serves a fraction of society. Many Americans are unable to invest in rooftop solar; they may be renters or lack the upfront money required for installations or live in locations […] More

    Bridging the information gap in solar energy

    Just 30 seconds into their walk to the town center of Kitale, in Kenya, where they would later conduct a focus group about locally available solar energy options, Elise Harrington and her research partner came across a vendor selling a counterfeit solar lantern. Because they had been studying these very products, they knew immediately it […] More

    Study: Even short-lived solar panels can be economically viable

    A new study shows that, contrary to widespread belief within the solar power industry, new kinds of solar cells and panels don’t necessarily have to last for 25 to 30 years in order to be economically viable in today’s market. Rather, solar panels with initial lifetimes of as little as 10 years can sometimes make […] More
