Eco Factor: Light uses water from a stream to generate energy.
Governments over the globe spend handsomely on maintaining night lights for the inner city streams, in order to make perilous rivers safe for the residents. Korean industrial designer Jihwan Park is trying to make the job less expensive with a concept product he calls the Stepping-Stone Light.
This sustainable lighting solution comes in the form of stepping stones where continuous flow of water from the stream turns a hydroelectric turbine to generate electricity. This energy is used to power a set of LED bulbs embedded within the stepping stones. The system can be used as a safety device for perilous rivers and deep valleys.
