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 hit the streets of Detroit to bring you the hottest hybrid vehicles and electric cars from the 2012 North American International Auto Show! We saw automakers unveil scores of sexy supercars like the Lexus LF-LC coupe, the Chevy MiRay, and the NSX concept hybrid, and we also showcased more realistic street-ready vehicles like Ford's Fusion Energi plug-in hybrid, VW's brand new hybrid Jetta, and Via Motors' VTRUX extended-range EV pickup. We also peered into the future of sustainable transportation as we brought you the finalists in Michelin's city car design challenge, we learned that the world's largest driverless personal transit system is set to break ground in India, and we saw the UK green light the first phase of its new HS2 high-speed rail line.

It was also a bright week for alternative energy as MIT scientists discovered a way to make more efficient solar plants modeled after sunflowers and Sweden announced plans for a massive 700 megawatt wind farm in the Baltic Sea. Meanwhile, we learned that Rwanda's poo-powered prisons are able to produce 75% of their power from human waste, we showcased plans for an energy-generating rolling suitcase that charges your gadgets, and we saw the launch of several shining solar-powered devices - OLPC's XO3 tablet computer and the sun-powered Solarkindle e-reader cover.

In other news, this week we rounded up our favorite eco gadgets from CES 2012 - including a hydrophobic nanocoating that makes any gadget completely waterproof. We also saw 200 Chinese works construct a 30 story prefab building in just 15 days, and we watched superman fly across a cute animated LEGO TV. Finally, we brought you the latest and greatest developments in wearable technology - including a set of smart sunglasses that merge virtual information with the real world, a set of bone-conducting earphones, and a set of motorized skates that can be attached to any boring old pair of shoes.
