Inhabitat's Week in Green: electric taxis, paper robots and a cathedral of 55,000 LEDs

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.

This week Inhabitat saw the light as we reported on several spellbinding new projects around the world -- including an incredible cathedral made from 55,000 LEDs and a glowing prefab pod building modeled after the genetic structure of plankton. We also showcased a luminous forest of thousands of "Frozen Trees" and a high-flying F-Light made from a recycled airplane, and also reported on Toshiba expanding its line of LEDs. Meanwhile, as the lights fire up Lucas Oil Stadium we shared seven ways Super Bowl 46 is going green, took a look at the first organic concessions ever to offered at a Super Bowl, and got things cooking with six delicious recipes for game time snacks

Eco transportation also blasted off from the starting line as London's first zero-emission electric taxis hit the streets, and Stanford unveiled plans for electrified roads that automatically charge EVs. We also saw Scotland launch the world's first hybrid sea-going ferries, while Agence 360 did cyclists a favor by designing a nifty ultra-compact foldable bike helmet. Meanwhile, Chevrolet announced plans to put environmental impact stickers on all of their cars by 2013, the sun-powered solarGT car set off on a race across the United States, and we brought you a gorgeous set of long-exposure photos that make speeding trains look like laser beams.

In other news, renewable energy was a hot topic this week as researchers at MIT found a way to make solar panels from grass clippings, another team of scientists developed a hip-hop powered biomedical sensor and Britain mulled plans to install a new breed of radioactive waste-recycling nuclear reactors that could power the UK for 500 years. We also brought you several fun designs for aspiring little builders - a set of awesome paper robots and an industrial workbench for tots. Finally, since Valentine's day is around the corner we shared 10 red-hot gifts, along with 14 sexy sustainable skivvies.
