MIT researchers have developed a new two-step electrochemical process to remove carbon dioxide out of seawater, reports John Fialka for E&E News. The new approach “cuts energy costs and expensive membranes used to collect CO2 to the point where merchant ships that run on diesel power could collect enough CO2 to offset their emissions,” Fialka writes.
MIT spinoff Gradiant, a water treatment facility developer, is working on new technology aimed at limiting the amount of water needed to produce lithium, reports Annie Lee and Janet Wu for Bloomberg. Gradiant’s process “can vastly improve lithium recovery and allow almost all wastewater to be recycled, has been developed in connection with Schlumberger’s NeoLith Energy venture,” writes Lee and Wu.
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.
Researchers from MIT, the University of Southern California, Redfin, and the National Bureau of Economic Research found that property listings with flood risks were less likely to be looked at and bid on by potential homebuyers, reports Leslie Kaufman for Bloomberg.
MIT researchers have “developed a free-floating desalination unit consisting of a multilayer evaporator that recycles the heat generated when the water vapor condenses, boosting its overall efficiency,” reports Nell Lewis for CNN. “Researchers suggested it could be configured as a floating panel on the sea, delivering freshwater through pipes to the shore, or it could be designed to serve a single household, using it atop a tank of seawater,” writes Lewis.
The Emerald Tutu, a climate resiliency project in Boston led by Gabriel Cira ’08, is developing a system of floating wetlands designed to reduce coastal flooding by knocking down waves, reports Hannah Chanatry for WBUR. The Emerald Tutu was the winning project at the 2018 MIT Climate Changed Ideas competition. “Fundamentally, it’s like a giant sponge that fits around urban coastlines like we have here in Boston,” said Cira. “It buffers those coastlines from the intense effects of coastal storms.”
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.”
Research affiliate Jason Prapas founded Fyto, a company dedicated to developing hardware and software to automate and scale the production of aquatic plants, reports Christine Hall for TechCrunch. Prapas says that “Fyto’s technology taps into a farm’s waste streams as inputs to enable farmers to increase productivity and improve nutrient management while reducing production costs, water usage and greenhouse gas emissions, in some operations by over 50%.”
Infinite Cooling, an MIT startup, is developing a new system that can capture water from cooling tower plumes and could significantly reduce water consumption in evaporative cooling tower systems, reports Sonal Patel for Power Magazine. “The technology that is developed could lead to significant water savings and improve water quality with minimal energy cost,” explained members of Prof. Kripa Varanasi’s lab.
Siblings Gia Schneider ‘99 and Abe Schneider SM ‘03 co-founded Natel, a company dedicated to developing sustainable, climate-resilient hydropower, reports Amy Gunia for TIME. “The siblings hope that what they’re doing can help demonstrate a more sustainable approach to renewable energy – proving that companies shouldn’t have to choose between what’s good for the environment and what works economically,” writes Gunia.
Forbes contributor Jeff Kart writes that a new study by MIT researchers finds that yeast, an abundant waste product from breweries, can filter out even trace amounts of lead. The researchers demonstrated that in just five minutes “a single gram of the inactive, dried yeast cells can remove up to 12 milligrams of lead in aqueous solutions with initial lead concentrations below 1 part per million.”
MIT researchers developed a suitcase-sized, portable desalination device that can turn salt water into drinking water with the push of a button, reports Elissaveta M. Brandon for Fast Company. Brandon writes that the device could be a “vital tool for remote island communities, seafaring cargo ships, and even refugee camps located near water.”
Motherboard reporter Audrey Carleton writes that MIT researchers have developed a “filter-less portable desalination device that uses an electrical field generated by solar energy to repel charged particles like salt, bacteria, and viruses.” Research Scientist Junghyo Yoon explains that: “All indicators tell us that water scarcity is a growing problem for everyone due to rising sea levels. We don’t hope for a grim future, but we want to help people be prepared for it.”
A new portable, solar-powered desalination device developed by MIT researchers can create potable drinking water with the push of a button, reports Tony Ho Tran for The Daily Beast. “The device doesn’t rely on any filters like traditional desalination machines,” writes Tran. “Instead, it zaps the water with electric currents to remove minerals such as salt particles from the water.”
Newsha Ghaeli ’17 - president and co-founder of Biobot, a public health research, data and analytics firms that has developed and promoted wastewater surveillance technology - speaks with Vox reporter Muizz Akhtar about how wastewater surveillance can be used to predict and prepare for future pandemics. “Our vision is that this is a permanent infrastructure layer on our sewer systems, so that it becomes one of the core kinds of pandemic preparedness in this country and disease surveillance globally,” says Ghaeli.
