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 several incredible feats of green architecture reach for the stars as Richard Branson unveiled the world's first commercial spaceport and a lunar solar power tower won the Moon Capital International Design Challenge. We were also impressed by Snøhetta's design for a massive möbius strip-shaped particle accelerator and we caught the groundbreaking of what will be one of the world's most efficient solar skyscrapers in Korea.

Ultra-efficient autos blazed a trail this week as an electric audi shattered a world EV distance record by traveling 372 miles on a single charge. We also caught a glimpse of the future of green transportation as major auto manufacturers unveiled a set of incredible eco concept cars, and we caught wind of a plan to bring these insane traffic-straddling buses to the United States.

In other news, we learned that iPhones and other communication devices may have potentially deadly side effects for kids, and we showcased several innovative designs for safer cycling - an inflatable airbag collar that automatically pops up to prevent injuries and a crash helmet that makes a stink when it cracks.

Finally, to celebrate Halloween we rounded up a ghastly array of ghoulish green designs - from a skeletal x-ray lamp to a skin-crawling camera made from a human skull to a company that will press your mortal remains into a vinyl record. Happy Halloween!
