The appropriately monikered Hank Green runs and edits this blog, designed to highlight the best in planet-preserving technology. Be it an ultra-fast, energy-producing wind turbine in Denmark, a new bioplastic made from shrimp-shell waste (really) or the latest news on electric airplanes, the Montana resident parses the latest on research, cool products and Earth-saving innovators. Green, who started the blog as a graduate-school project, says he spends most of his time “thinking about how our brains can save our planet.” The purpose isn't so much a guide, but rather an exploration of the “symbiosis between nature and technology.” www.ecogeek.org.
