Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.
This week aviation fans witnessed a world's first as AeroVelo's human-powered helicopter won the elusive $250,000 Sikorsky Prize by hovering 10 feet off the ground for more than 60 seconds. The Solar Impulse sun-powered airplane also broke boundaries by completing the first sun-powered trip from coast to coast -- and Inhabitat was on the scene at New York's JFK Airport to meet it. In other green transportation news, ABB recently announced plans to build the world's largest nationwide network of EV fast-charging stations in the Netherlands. NASA's autonomous solar-powered polar rover, the GROVER, completed initial sub-zero field tests in Greenland, proving that it can withstand 30 MPH winds and temperatures of -22 F. Roads are an integral part of our carbon-heavy automotive transportation system -- but a new type of smog-eating pavement could actually combat emissions and clean the air. And Inhabitat took a look at the world's most beautiful urban street, a gorgeous tree-lined oasis in Porto Alegre, Brazil.
