Parking scofflaws have come up with several ways to thwart time restrictions in parking spaces — wipe the chalk off your tires, switch license plates (which we would never recommend). Those solutions are now out the window thanks to underground sensors that alert the authorities when you’ve overstayed your welcome.
Chicago was nicknamed the Windy City because of its blowhard politicians, not the powerful gusts off Lake Michigan. But a new parking garage took the name to heart regardless and installed this amazing helix-shaped wind turbine system inside the building, making urban turbines not only cool, but functional.
This summer, 12 turbines started spinning at Greenway Self-Park, which bills itself, somewhat oxymoronically, as Chicago's first Earth-friendly parking garage.
Looking for open parking spaces in the city is one of the more teeth-grinding rituals for drivers, but researchers at Rutgers University in New Jersey may have hit upon a relatively low-cost solution. They combined ultrasonic sensors with GPS to create digital maps of available parking spaces for Web-based navigation systems, according to Technology Review.
