If you want to avoid catching the latest cold or flu that seems to be making the rounds, the best advice is always to wash your hands often, especially before eating. But that's not always possible, and so we rely on the surfaces we touch being kept clean. LG just made one hive of germs much cleaner by inventing an escalator handrail sterilizer.
The Handrail UV Sterilizer as it is called, is actually the creation of LG's Innotek arm and uses UV LED technology to continuously disinfect the handrail as it travels. LG says it's good enough to kill 99.99% of germs, meaning you won't get ill from touching a handrail fitting with this sterilizer.
Installation involves clipping the the sterilizer, which is about half the size of a sheet of A4 paper, on to the handrail. Once attached, UV rays with a wavelength of 278 nanometers are beamed on to the rail as it passes by "destroying the DNA of germs."

As it uses light, there's no chemicals involved so it simply requires power, which it gets from the movement of the escalator handrail, meaning you don't even need to hook it up to a power supply directly. It's about as close as you can get to an install-and-forget germ killer.
There's no word on pricing or availability yet, but the Handrail UV Sterilizer has already attained the CE certificate from the European Union meaning it's basically ready to go as soon as LG choose to offer it to customers.
