How many of you use a hand sanitizer immediately after their subway ride? Ah, so many of us do this! In fact, most public spaces now keep a sanitizer bottle handy for those who are obsessive about cleanliness and germs. Building on this and the fact that enclosed spaces like subway stations are a thriving bed for germs, this set of Korean Designers have designed the GHOST Drone. Functional Drones are not new (rescue drone, fire extinguishing drones etc.), but what caught my fancy about the GHOST is that, it hopes to solve a genuine problem. The housekeeping staff of stations are efficient, but there is little that they can do about the quality of air and the kind of germs that float around a subway station. The GHOST Drone flies around the station, spewing UV light via its UV LEDs and sterilizes the air-space around. Easy to operate and focused on providing a healthier environment. Through an all-way-sensor, it has a smooth flight and efficient sterilization process. Using UV LEDs, ‘GHOST’ with a stationed drone in the subway space is a space care system that provides sterilization service inside the subway, and is designed to quickly and completely sterilize the straight space inside the train. The light goes out, and during the time everyone is asleep, ‘GHOST’ will float for hygienic subway service. Designers: Off Garage Studio , Yungi Min, Sunghyun Kwon, Ikhyeon Kim & Byeongjae Ha UV sterilization is the most ecofriendly disinfection method in existence, and is used throughout our lives for various purposes, including food hygiene, water treatment and surface sterilization. In addition, the output of more than 100 milliwatts (mW) can rapidly sterilize to the air and applie to many aspects of our lives. GHOST with a station inside the train moves in the interior space of the train, sterilizes it with UV, and returns to the station to charge. New York Subway Tokyo Subway Munich subway Beijing subway
