MIT spinoff Quaise Energy is transforming a millimeter-wave drilling technique from nuclear fusion experiments to tap geothermal energy, reports Mark Bergen for Bloomberg. “The company’s drill – it is building three prototypes in laboratories – is about 100 feet tall and looks like convential equipment used in the oil and gas industry,” writes Bergen. “Except built into the center of the drill is a gyrotron, an electrical vacuum designed to heat plasma in thermonuclear fusion machines. 

In a cartoon for The Boston Globe, Sage Stossel highlights research underway at the MIT Plasma Science and Fusion Center, where scientists are working on developing the future of fusion energy.

Prof. Christopher Knittel speaks with Wall Street Journal reporter Andrew Duehren about how European governments are beginning to experiment with new ways to control energy prices.“Especially with the European energy-market policy interventions, what policy makers do not want to do is exacerbate these problems with their policies, and my fear is that is what these proposals would do,” says Knittel.

Prof. Emeritus Donald Sadoway and his colleagues have developed a safer and more cost-effective battery to store renewable energy, reports David Abel for The Boston Globe. The battery is “ethically sourced, cheap, effective and can’t catch fire,” says Sadoway.

Research led by Prof. Michael Howland has found that adjusting the orientation of wind turbines on a farm can reduce the wake effect and boost the total output, reports Maria Perez Ortiz for Wired. “Howland and his team’s algorithm first uses atmospheric physics and operational farm data—such as temperature and wind conditions—to estimate the wakes that turbines are creating and how these are impacting other turbines,” writes Ortiz. 

Prof. Michael Howland speaks with Camille Bond at E&E News about his research, which suggests that finding the ideal position for individual wind turbines could increase the overall efficiency of the entire wind farm. “If we're expanding wind energy quite substantially, it's important that we design the wind farms in the best way and we control them in the best way to achieve that goal,” said Howland.

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 and elsewhere have developed a new cost-effective battery design that relies on aluminum ion, reports Robert F. Service for Science. “The battery could be a blockbuster,” writes Service, “because aluminum is cheap; compared with lithium batteries, the cost of materials for these batteries would be 85% lower.”

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.”
