The Seoul Metropolitan Government on Wednesday installed an experimental charging booth for smartphones and tablet PCs along the Cheonggye Stream in Seoul.
The eco-friendly chargers are hydro-powered by the stream itself.
A small hydro generator operated only by a small turbine was set up about 20 m from the booth to supply power to five chargers.
"We'll do a test run for three months, and depending on the result, we may build more charging booths," a city spokesman said.
