Berlin design student Tobias Trübenbacher has developed a lamp post with an integrated wind turbine that produces its own renewable energy and only lights up when needed.
Papilio was designed to slash the light pollution and emissions associated with street lighting and mitigate its impact on both humans and animals as well as the environment.
Papilio can be mounted to walls or set up as a freestanding lantern. The lamp should ideally be placed between three to six metres above ground, where ground-level winds are the strongest.
These winds are harnessed by a turquoise, pinwheel-shaped wind turbine with four aerodynamic rotor blades made of folded sheet metal.
