Inhabitat's Week in Green: nanotech tea, pollution-sucking stones and the world's most efficient car


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 we saw the shattering of a new record as NYC's high-tech One Bryant Park skyscraper achieved LEED Platinum certification, making it the world's greenest office tower. We also turned over a new high-tech paving stone that can absorb airborne pollution and visited a hyper-efficient solar city in Germany that is able to produce four times the amount of energy that it consumes.

The world of efficient transportation is also heating up as four electric vehicles blazed a trail through Europe in a race to circle the globe in 80 days. We also watched a team of DeLaSalle students unveil the world's most efficient zero-emissions car and took a look at an incredible electrified Porsche. Finally, sun-powered transportation reached for the stars as NASA unveiled plans to launch its solar NanoSail into space this fall.

Nanotechnology is also changing lives here on earth as researchers revealed a nanotech tea bag that can purify a liter of drinking water for less than a penny. And speaking of liquid refreshment, this week we took a plunge in Manhattan's new recycled dumpster swimming pools -- and brought back tons of photos! But summer won't last forever, so if you're gearing up to head back to school next month be sure to check out our top picks for the best solar-powered book bags.
