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.
Buildings are among the biggest energy users, but new developments in the design world could help change that. ArchiBlox recently unveiled Australia's first carbon-positive prefab home -- in other words, the house produces more energy than it uses. The gorgeous 800-square-foot structure is now on display in Melbourne's City Square. In other architecture news, Google just unveiled plans to build a giant bubble in Mountain View! The new Googleplex headquarters will be a biosphere-filled utopia designed by Heatherwick Studio and BIG. Speaking of BIG, the Danish architecture firm recently unveiled plans for a luminescent, geodesic dome biomass power plant. The rainbow-colored dome wouldn't just produce green energy; it would also serve as a public park.
