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.
The motion-activated design uses wind ? a natural, renewable energy source ? to power its turbines.

"If we want to maintain a future worth living in, we urgently need to transform our cities into climate-neutral, sustainable and less harmful places," Trübenbacher told Dezeen.
"We urgently need to tackle light pollution and the loss of biodiversity coming along with it. This can only happen if cities generate energy themselves ? through locally embedded, decentralised systems and 'prosumer' products in huge quantities spread all over urban spaces. In this context, wind represents an often underestimated yet constantly growing potential." Its matt black body is designed to reflect as little light as possible
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.
