Clear Win is a small unit that is attached to both sides of an escalator at the end where people get on, so that the handrails pass through them. Powered by a dynamo, which generates electricity from the constant movement of the escalator, the product beams sterilising ultraviolet light (specifically the UV-C wavelengths) on to the handrail as it moves through it, destroying all viruses and bacteria. Hats off to Kim Kyeong Yeon and Kim Yoo Cheol.
