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.
Now that green design is entering the mainstream, we're beginning to see the design community tackle larger, more ambitious projects using eco-friendly techniques. Case in point: This week, San Francisco transformed the Bay Bridge into the world's largest light sculpture by outfitting it with 25,000 LED lights. Because the lights are so energy-efficient, it will cost just $15 per night to run the installation. In Hamburg, workers are putting the finishing touches on the world's first algae-powered building, which is set to open this month at the International Building Exhibition. A company in Tokyo recently demonstrated a new skyscraper deconstruction technique that harvests energy from the demolition process and salvages almost every piece of the building for reuse. And in Copenhagen, work has begun on a combined ski resort and waste-to-energy plant, which will convert the city's trash into energy that powers the resort.
