‘Flow’ by Alberto Vasquez, is a bamboo-made, self maintaining public lighting which operates on the principle of vertical wind turbine. The whole lamp disintegrates in nature except for the electronics – LEDs, wires and dynamo – which after time can be recycled without downcycling. Due to the simple junctions and mechanics, it can also be produced by the local unskilled workforce. The light sources situated at the ends of the wind blades can form continuous lighting surface or slow, waving movements and play of light, depending on the speed of the rotation. Due to its spiral form, the lamp can hold the wind from every direction.
