Flow concept turns wind into light with novel bamboo turbine

Grid-powered street lighting is something that many of us take for granted, but there are parts of the world where electricity is a scarce resource and when the sun goes down, local pedestrian traffic in areas where public lighting is not abundant can all-but cease due to safety concerns. In searching for an inexpensive off-grid solution for places like the Colombian city of Cartagena, designer Alberto Vasquez looked to the wind for help. His Flow concept makes use of readily-available bamboo for the construction of a vertical wind turbine in a similar vein to the Power Flowers concept, but with LED light modules at the end of each blade. As the wind catches the blades, the LEDs light up the walkway beneath.
