Researchers at MIT have discovered what makes ancient Roman concrete “exponentially more durable than modern concrete,” reports Jim Morrison for Wired. “Creating a modern equivalent that lasts longer than existing materials could reduce climate emissions and become a key component of resilient infrastructure,” writes Morrison.
An MIT study has found that the wide spread adoption of self-driving cars could lead to increased carbon emissions, reports Rima Sabina Aouf for Dezeen. “The study found that with a mass global take up of autonomous vehicles, the powerful onboard computers needed to run them could generate as many greenhouse gas emissions as all the data centers in operation today,” writes Aouf.
Boston Metal, an MIT startup, has developed a way to generate steel without releasing carbon dioxide emissions, reports Catherine Clifford for CNBC. The company “plans to begin construction of a demonstration steel plant in 2024 and a commercial sized plant in 2026,” says Boston Metal CEO Tadeu Carneiro.
MIT startup Boston Metal is developing technology to decarbonize steel production, reports Ed Davey for the Associated Press. “Boston Metal said it can eliminate all carbon dioxide from its steel production and hopes to ramp up production to millions of tons by 2026,” writes Davey.
A new study by MIT researchers finds that “the energy required to run computers in a future global fleet of autonomous vehicles could produce as much greenhouse gas emissions as all the data centers in the world,” reports Sharon Udasin for The Hill. The researchers found that “1 billion such cars, each driving for an hour daily, would use enough energy to generate the same amount of emissions that data centers do today.”
Politico reporter Derek Robertson writes that a new study by MIT researchers finds the computing power required to replace the world’s auto fleet with AVs would produce about the same amount of greenhouse gas emissions as all the data centers currently operating. Robertson writes that the researchers view the experiment “as an important step in getting auto- and policymakers to pay closer attention to the unexpected ways in which the carbon footprint for new tech can increase.”
MIT researchers have discovered that ancient Romans used calcium-rich mineral deposits to build durable infrastructure, reports Daniel Cusick for Scientific American. This “discovery could have implications for reducing carbon emissions and creating modern climate-resilient infrastructure,” writes Cusick.
Graduate student Soumya Sudhakar speaks with BBC Digital Planet host Gareth Mitchell about her new study showing that hardware efficiency for self-driving cars will need to advance rapidly to avoid generating as many greenhouse gas emissions as all the data centers in the world.
Bloomberg reporter Akshat Rathi spotlights Sublime Systems, an MIT startup developing new technology to produce low-carbon cement. “Sublime’s solution involves splitting the cement-making process into two steps,” explains Rathi. “The first step is to make calcium—the key element in limestone—in a form that’s ready to chemically react with silicon—the key element in sand. Sublime reduces energy use and carbon emissions in this step by avoiding limestone and using electricity, rather than coal-fired heat.”
Prof. Admir Masic speaks with NPR host Scott Simon about the concrete blend used by the ancient Romans to build long standing infrastructures. “We found that there are key ingredients in ancient Roman concrete that lead to a really outstanding functionality property in the ancient mortar, which is self-healing,” explains Masic.
Using statistical modeling, MIT researchers have found that the energy needed to power a fleet of fully autonomous EVs could generate as much carbon emissions as all the world’s data centers combined, reports Andrew Paul for Popular Science.
Washington Post reporter Pranshu Verma writes that a new study by MIT researchers finds the “future energy required to run just the computers on a global fleet of autonomous vehicles could generate as much greenhouse gas emissions as all the data centers in the world today.”
Deepak Dugar MBA ’13, PhD ’13 founded Visolis, a biomanufacturing company developing carbon-negative, high-performance materials, reports John Cumbers for Forbes. “We use biology to make platform molecules. And then we use chemistry to turn them into a lot of different products. Because of this unique combination, we have an advantage both in terms of market as well as cost of technology development,” says Dugar.
On a recent episode of “Shark Tank,” Amrita Saigal '10 scored a $250,000 investment in her company Kudos, which is focused on making disposable diapers from sustainable and natural materials, reports Megan Sauer for CNBC. Saigal, who also founded a company called Saathi that makes sanitary napkins from banana peel fibers, notes she was inspired by seeing “just how much plastic we were putting into sanitary napkins and diapers.”
Reuters reporter Will Dunham writes that a new study by MIT researchers uncovers the secret ingredient that made ancient Roman concrete so durable and could “pave the way for the modern use of a replicated version of this ancient marvel.” Prof. Admir Masic explains that the findings are “an important next step in improving the sustainability of modern concretes through a Roman-inspired strategy.”
