Plus, making lithium-ion battery electrodes from sugar-filled wastewater left after the beer-making process.

Over the next 15 years, the Dutch city of Eindhoven will solicit feedback from residents about how smart lighting should be deployed throughout the area. The goal of the program, Vision and Roadmap Urban Lighting Eindhoven 2030, is to develop a smart, sustainable city based on what’s important to citizens. The participatory planning process could lead to the use of lighting on demand at night or to guide first responders to an accident. Source: New Atlas


The number of American adults who are in a facial recognition database used by law enforcement. A report by Georgetown University’s Center on Privacy and Technology found that at least half of all U.S. adults have a driver’s license in one of the 26 states that allow police to search those photos to find potential matches.

Energy from Hoppy Goodness: To make better use of the ingredients discarded during the beer-making process, engineers at the University of Colorado Boulder have devised a way to make lithium-ion battery electrodes from the sugar-filled wastewater. The water, which can’t go down the drain as is, is well suited for cultivating a fast-growing fungus that becomes the carbon-based electrode. While the process isn’t new, it can be easily scaled up to make use of this material, which could be especially beneficial in Colorado where there are more than 250 breweries. Source: TreeHugger
