Inhabitat's Week in Green: sexy green cars, glass strong as steel, and Tianjin's Eco-City revealed

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 Inhabitat brought you unveilings of the world's hottest new eco vehicles as we hit the floor of the Detroit Auto Show and rounded up the seven sexiest green cars on display. We also took a first look at Toyota's new Tesla-infused RAV4, and we caught up with Venturi's powerhouse electric concept car. And if unconventional transportation spins your wheels, don't miss the shape shifting Uno 3 electric scooter and this masterfully-crafted Tron segway that could out-geek a lightcycle.

We also looked at several groundbreaking building systems that stand to make our cities stronger and more sustainable, starting with a new type of flexible superglass that is stronger than steel. Meanwhile, Sweden is soaking up body heat from public places to help heat buildings, China unveiled plans for a futuristic eco city, and several offices in Minnesota flipped on a set of souped-up ceiling lights capable of broadcasting wireless internet.

In other news, the world of renewable energy is jolting for joy as Southwest Wind Power unveiled the world's first fully smart grid-enabled windturbine. We also checked out a new ultracapacitor that can charge a power drill in 60 seconds, and researchers are working on energy-generating fabrics that can transform your t-shirt into a power plant. Finally, this week we wrapped up our CES coverage with a look at the best green gadgets from this year's show, and we flexed our creative capacity with 5 tech projects for kids that foster creativity and critical thinking.
