decorated going: Inhabitat's week in green: solar powered toilet, pollution-fighting mural and the world's largest rooftop wind farm

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.

Hear those school bells in the distance? It's hard to believe, but the start of the school year is just a few weeks away -- and all week we've been rounding up some of our favorite eco-friendly back-to-school essentials. From green school supplies to sustainable backpacks, we've got all your back-to-school needs covered. And to top it off, we're giving away a laptop-charging Voltaic solar-powered backpack (worth $389) stuffed with green school supplies for a total prize package worth over $500. If we could go back to school and live in any dorm, we'd probably choose Copenhagen's Tietgenkollegiet dorm, a circular building with community kitchens, cafes, music rooms and a central courtyard. And if we could choose any gadget to take with us, it would have to be the P&P Office Waste Processor, which can transform a basket full of waste paper into fully-formed pencils.
