Looking for a clever way to spark conversations about renewable energy? Need a new lamp to illuminate your favorite outdoor reading nook? Through the wonder of 3-D printing technology, the solution to both of these needs may be available at the push of a button.
Designed by Beijing-based architect Margot Krasojevic, the “Air Turbine Light” utilizes moving breezes to generate the electricity needed to illuminate its LED bulb. The difference between this wind-powered lamp and others we’ve featured in the past is that instead of buying or building it, Krasojevic simply printed it.
As noted in this review, the lamp works by incorporating the same efficient design as a vertical axis wind turbine, but in this case the “blades” are the lamps outer shell which is attached to the axis via a rotor arm. “The digital model simulates the dynamic qualities of the design by working out and applying the physics of wind speeds and direction which has influenced the design and the aerodynamics of the form,” writes Krasojevic.
An alternator or generator produces electricity when the shaft is rotated, in this instance by a dynamo which lights the LED. The body of the light is attached to a vertical axis which turns a diode rotor that transforms the movement into light. The body is made from white ceramic which is strong yet light enough to be turned by a gentle breeze. Here’s the lamp “in action”:
