John Hardy at TEDGlobal 2010

Join John Hardy on a tour of the Green School, his off-the-grid school in Bali that teaches kids how to build, garden, create (and get into college). The centerpiece of campus is the spiraling Heart of School, perhaps the world’s largest freestanding bamboo building.

TED is a nonpartisan nonprofit devoted to spreading ideas, usually in the form of short, powerful talks. TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 110 languages.
