Bjarke Ingels Group (BIG) wants to project carbon-dioxide (CO2) emissions into the sky in a way that draws attention to air pollution. Last week the Danish firm—in partnership with German studio Realities United, Peter Madsen's Rumlaboratorium, and the Danish Technical University—launched a Kickstarter campaign to crowdfund $15,000 for the final prototype of a smokestack-turned-art piece that will eventually be installed at its sustainable waste-to-power plant currently under construction in Copenhagen, Denmark. The working chimney will turn the plant’s CO2–infused emissions into 100-foot-diameter smoke rings that puff​​​ gracefully into the clouds every 45 seconds, each representing 1 ton of emissions. And if all that wasn’t enough, in BIG’s whimsical fashion, the entire facility will double as a ski slope. Skiers careening down the hill can look up and see the plant's CO2 footprint imprinted in the sky. [Kickstarter + Fast Company

MIT's Media Lab is developing a network of sensors that will track how pedestrians move through an urban space in Boston, using a $35,000 grant from the Knight Foundation. [CityLab]

Do you miss your childhood Lite-Brite? San Francisco studio Hero Design has revised Hasbro’s concept for grown-ups—at 42 times the size. Rather than removable pegs, however, the studio's wall-mounted board is fitted with 464 LED dials that change color with a twist. [Designboom

Blocking specific background noises—such as that of a faulty HVAC system—is challenging because current abatement technology can't parse sounds. A pizza-sized plastic disk from researchers at Duke University could change that. Its honeycomb structure is designed using an algorithm to alter certain sound waves, muffling some noises but not others. [Nature]  


The race to 3D print better building components continues. The most recent development: Italian additive-manufacturing firm WASP, along with researchers at the universities of Naples and Pavia, both in Italy, created a 3-meter-long, 3D-printed modular concrete beam with integrated steel reinforcement.

The amount of green space in a neighborhood offers compelling insight into the economic health of its residents. A new app from Portland State University, in Oregon, helps urban planners manage the impact of poor air quality by showing where a lack of vegetation corresponds with poverty​. [Smithsonian.com]
