julianbyne: Inhabitat's Week in Green: solar supertrees, pee-powered plasma and a bug-eyed mantis shrimp with a serious right hook

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.

It's been a big week for energy-efficient breakthroughs in the scientific community. Scientists at MIT developed a new type of textured nano surface that could reduce the thickness of silicon used in solar panels by more than 90 percent, bringing down the cost of photovoltaic technology. Meanwhile, in the land down under, researchers at the Australian National University are working on a pee-powered plasma thruster that could make deep space missions more feasible. Also this week, a team of engineers from MIT developed a new glucose fuel cell that runs on the same sugar that powers the human body and could be used for brain implants.
