About the challenge
Resolving urban air pollution. Designers in China have developed a concept for “parasitic robots” which attach to city billboards to suck in carbon dioxide and purify the air. The heat from the light of the billboards does the trick.
Description
Designers in China have developed a concept for “parasitic robots” (they look like insects) which attach to city billboards to suck in carbon dioxide and purify the air. The company Fast Co Exist has developed these robots and is hoping to attach them to the neon signs in Hong Kong, where they would collect urban pollution in the daytime and use the heat from the neon lighting at night to harvest the carbon dioxide into an energy source.
