We’ve seen numerous endeavors undertaken by individuals, organizations and government bodies alike, each attempting to bring our world into a more sustainable state of being. But even with all these new initiatives, can we really trust that society is moving at a speed effectual enough to place us ahead of the perils of climate change? As part of a two-week workshop on wearable, interactive responses to environmental change, Brazilian designers Martina Pagura and Pedro Nakazato Andrade created W/Air, an oxygen-filtering breathing “necklace” that removes carbon dioxide from the air, stores it in a battery-like device, and then converts it into electricity for later use. While this necklace may look like it’s best suited for the likes of Darth Vader, we’d certainly wager it’s a better bet than slow asphyxiation via toxic fumes. Check out the video ahead!
