Water-powered phone chargers are coming to downtown Seoul !! Welcome to the first week of Autumn for 2014 in Seoul, the city that just keeps on getting smarter, as demonstrated by the recent news that citizens will soon be able to recharge their cell phones at the Cheonggyecheon via hydroelectric turbines installed in the urban stream’s flowing waters. Unless you’ve made a habit of carrying around a solar charger, topping off your phone outdoors can be a bit of a challenge. Well, unless you’re living in South Korea. The city of Seoul just announced that it’s building a series of outdoor recharging stations along the Cheonggyecheon, a manmade stream in the city’s downtown area. The chargers won’t draw from the city’s power grid, however — they’ll draw current from a collection of hydroelectric turbines embedded in the stream. The project’s developer says the stations will be able to fully charge most devices in 2-3 hours. If the five stations currently in production turn out to be a hit, the city says it will consider expanding the network. See? Low battery life is no excuse for avoiding the great outdoors.
