Energy efficiency

Writing for The Hill, Principal Research Scientist Randolph Kirchain and Research Scientist Hessam Azarijafari address how the condition of the nation’s road system impacts transportation emissions. “Investing in a higher-performance road system is a lever within state control that will improve the efficiency and carbon emissions of all vehicles, regardless of how each is powered,” write Kirchain and Azarijafari. “Smoother, stiffer roads allow cars to travel along it more efficiently. Every time a car tire traverses a bump, crack, or pothole, energy is wasted.”

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.

Fast Company reporter Connie Lin spotlights how Algorand, an MIT startup founded by Prof. Silvio Micali, dimmed the lights in Times Square on April 21 to help conserve energy and demonstrate how cryptocurrency could reduce energy consumption. Algorand has developed a carbon-negative blockchain protocol and “utilizes a pure proof-of-stake consensus mechanism to verify authentic transactions.”

The MIT AI Hardware Program seeks to bring together researchers from academia and industry to “examine each step of designing and manufacturing the hardware behind AI-powered technologies,” reports Emily Bamforth for EdScoop. “This program is about accelerating the development of new hardware to implement AI algorithms so we can do justice to the capabilities that computer scientists are developing,” explains Prof. Jesús del Alamo.

The MIT AI Hardware Program is aimed at bringing together academia and industry to develop energy-optimized machine-learning and quantum-computing systems, reports Katyanna Quach for The Register. “As progress in algorithms and data sets continues at a brisk pace, hardware must keep up or the promise of AI will not be realized,” explains Professor Jesús del Alamo. “That is why it is critically important that research takes place on AI hardware."

Fortune reporter Tristan Bove spotlights a study led by economists from MIT, Stanford, the University of Chicago and Mexico’s ITAM on how workers are spending their time while working from home. “Pandemic habits give Americans around 70 minutes of extra free time a day,” writes Bove. “The lion’s share of this, around 60 minutes, comes from getting rid of commuting, but workers have also spent around nine minutes less on average doing daily activities such as grooming or picking out fresh clothes.”

Economists from MIT, Stanford, the University of Chicago, and Mexico’s ITAM polled U.S. workers to see how the pandemic impacted American’s work from home setup, reports Nate DiCamillo for Quartz. “Overall, remote workers report that they’ve become more efficient at working from home than in office,” writes DiCamillo.

Writing for The Wall Street Journal, Prof. Yossi Sheffi notes that “just-in-time” (JIT) supply chains can help improve product quality and manufacturing processes, leading to reduced inefficiency. JIT “reinforces resilience because it strengthens the relationships along the supply chain between companies, their suppliers and customers,” writes Sheffi. “Close relationships allow companies to react collaboratively to supply-chain disruptions.”

During CNBC’s Technology Executive Council summit, Prof. Christopher Magee related how “allocating R&D resources efficiently is a critical skill, but one that most companies struggle with,” according to CNBC reporter Susan Caminiti. Magee's latest research “uses AI to predict the speed of the development of specific new innovations, all with the goal of deploying resources smartly and effectively,” writes Caminiti.

Writing for The Wall Street Journal, Prof. John Sterman details how he reduced his personal carbon footprint, from commuting via bicycle to completing a deep-energy retrofit on his home. “The project was great fun, cost-effective and the house is far more comfortable,” writes Sterman. “But personal action, though essential, isn’t sufficient. Building a prosperous, safe and equitable world requires that we transform our economy and institutions. To do so we must act now. There is no time to waste.”

Nth Cycle, a company co-founded by Prof. Desiree Plata, has developed an extraction device that uses electric signals to identify valuable metals or black mass leftover from discarded electric batteries. “This modular system is easy to move and adapt and is far more efficient and environmentally friendly than the traditional methods of smelting or using a chemical wash to sort out the metals from the gunk,” writes Jon Chesto and Larry Edelman for The Boston Globe.

TechCrunch reporter Kate Park spotlights Catalog, a startup founded by MIT graduates that is “developing an energy-efficient, cost-competitive and more secure data storage and computation platform by using synthetic DNA.”

Boston Globe correspondent Scott Kirsner spotlights CubicPV, an MIT startup, which is creating solar cells that more efficiently convert sunlight into energy.

Prof. Kristala L. J. Prather speaks with Korie Grayson of C&EN about her career path and her work harnessing the synthetic power of microbial systems. Of the importance of mentorship, Prather notes, “The exponential way in which you can actually have a positive impact is by taking good care of the people who are placed into your academic and intellectual trust. That’s how we make a difference.”

In a Wired article, Prof. Carlo Ratti writes about how responsive sensors can help reduce energy usage in buildings. Ratti explains that, “by pursuing a tailor-made, non-standardised approach we can achieve not only better comfort levels for building users, but also a substantial reduction in energy consumptions: between 25 per cent and 40 per cent.”
