Inspired by the Chinese Lantern Festival, Polish designer Michał Pośpiech came up with a visionary and elegant idea: A flying air purifier that helps create a healthy microclimate outdoors. The wings of these machines have solar panels on the top and exchangeable filters underneath. Every movement they make circulates and cleans the air. The UrbanCONE can be steered using a smartphone. For now, it is still just in the design stage.
