This week President Barack Obama set the tone for the coming year in his 2013 State of the Union address, which advocated 3D printing and called for a speedy transition towards renewable energy to help combat climate change. The future of clean tech is already looking bright, as the world's solar power capacity just hit a record 101 gigawatts, and researchers found a new way to charge batteries by harvesting ambient electromagnetic waves from thin air. Speaking of batteries, a new lithium-ion battery developed by USC utilizes nano-sphere technology to store three times more energy while cutting charge time down to just 10 minutes. Clean tech is invading the kitchen as well -- behold the Biobot, a tabletop device that converts waste cooking oil into biodiesel.
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.
