Sublime Systems, a startup founded by Prof. Yet-Ming Chiang and former MIT postdoc Leah Ellis, is working to decarbonize cement making – a process which currently accounts for eight percent of global carbon emissions. “The world has a huge appetite for cement, and Sublime is working to scale its production to meet it,” writes Casey Crownhart for The Spark, MIT Technology Review’s weekly climate newsletter.
Prof. Yet-Ming Chiang co-founded Sublime Systems, a company that has developed a new method for producing cement that is powered by electrochemistry instead of fossil fuel-powered heat, reports Catherine Clifford for CNBC. “I believe climate change has pushed all of us into an extremely fertile, creative period that will be looked back on as a true renaissance,” says Chiang. “After all, we're trying to re-invent the technological tools of the industrial revolution. There's no shortage of great problems to work on! And time is short.”
Sublime Systems, an MIT startup, is on a mission to manufacture emissions-free cement, writes David Abel for The Boston Globe. “If we’re successful, this could be a way of making cement for millennia to come,” said Leah Ellis, chief executive of Sublime Systems. “What we’ve found is that we can bring tools from our technical training to these problems, and use them in new and creative ways,” said Prof. Yet-Ming Chiang, co-founder of Sublime Systems. “I believe it’s a very fertile time for this kind of reinvention.”
Boston Metal, an MIT startup, is developing a new method for producing steel that reduces carbon emissions, reports Catherine Clifford for CNBC. “The main goal of Boston Metal is green steel, but the company will also use its core electrolysis technology to produce tin, niobium, and tantalum metals from what is otherwise considered waste from the mining process,” writes Clifford.
The Economist spotlights how Boston Metal, an MIT startup, has developed a new process for creating steel that avoids producing greenhouse gas emissions. “Instead of releasing CO2 or steam, its approach produces pure oxygen—which is not merely harmless, but actually valuable,” The Economist notes.
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.”
Researchers from MIT’s Research Laboratory for Electronics have developed a portable desalinator that can turn seawater into safe drinking water, reports Ian Mount for Fortune. Research scientist Jongyoon Han and graduate student Bruce Crawford have created Nona Technologies to commercialize the product, writes Mount.
Loh Down on Science host Sandra Tsing Loh spotlights Prof. Cathy Wu and graduate student Vindula Jayawardana and their work developing a new method for self-driving vehicles that would help minimize idling at red lights. “In their method, self-driving can be taught to minimize stops at red lights. To make this work, traffic lights and self-driving cars would have sensors. This would let them check in with each other on their surroundings,” says Loh.
Prof. Desiree Plata speaks with AccuWeather senior on-air meteorologist Geoff Cornish about her research in using zeolite clay to control and remove methane emissions from the air. “So, the really interesting thing about zeolite is it has these cool pore spaces so when you drop copper into those pore spaces it can grab onto a methane molecule and attach an oxygen atom to it and that helps convert that methane into carbon dioxide which is a much less potent greenhouse gas and so the net benefit to the climate can be quite dramatic,” explains Plata.
TechCrunch reporters Kyle Wiggers and Devin Coldewey spotlight how MIT researchers developed a new technique for simulating an overall system of independent agents: self-driving cars. “The idea is that if you have a good amount of cars on the road, you can have them work together not just to avoid collisions but to prevent idling and unnecessary stops at lights,” write Wiggers and Coldewey.
Prof. Jessika Trancik speaks with Forbes contributor Peter Cohan about the carbon emissions associated with gas, hybrid and electric vehicles, and the site she and her research group developed to allow consumers to compare personal vehicles against climate change mitigation targets. “In most locations, compared to [gas-powered vehicles], EVs produce emissions savings greater than 30%,” says Trancik. "Most savings are greater depending on the geographic location, the electricity supply, and the vehicle model.”
MIT researchers have found that zeolite, a material used to soak up odors in kitty litter, can be used to grab methane out of the air, reports Angely Mercado for Gizmodo. “Zeolite has tiny pores that act like sponge, and the clay is pretty multifunctional: It can help improve water retention in soil, and it’s found in natural kitty litter,” explains Mercado.
Wall Street Journal reporter Ryan Dezember visited Prof. Desiree Plata’s lab to learn more about her group’s work developing a new tool to help address climate change. Plata and her colleagues “soaked an odor-eating clay used in cat boxes in a copper solution to create a compound that they say snatches methane from passing air and turns it into carbon dioxide, a much less harmful greenhouse gas.” The new technique has the “potential to greatly reduce the amount of methane in the atmosphere and slow warming temperatures on the planet.”
Lecturer Susan Murcott and graduate student Imane Ait Mbiriq speak with Paris Alston and Jeremy Siegel of GBH’s Morning Edition about the MIT Climate Clock, a creation from the D-Lab that will be projected on the Green Building through May 27. “Our overall vision is that we have climate clocks in every K-12 school, in every university campus in the United States and even in the world, so that people can wake up to the reality of this new age and take action,” says Murcott.
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.”
