A remarkable experimental light source runs on sunlight, carbon dioxide and water.
Designer Mike Thompson combines the seemingly disparate world of algae and home appliances in his Latro Lamp. Using a recently developed technique, Thompson has created a lamp that is powered by harnessing electrical currents generated during photosynthesis.
He explains how the Latro works:
Latro (latin for thief) incorporates the natural energy potential of algae and the functionality of a hanging lamp into its design. Synthesising both nature and technology in one form, Latro is a living, breathing product. Algae are incredibly easy to cultivate, requiring only sunlight, carbon dioxide (CO2) and water, offering a remarkably simple way of producing energy. Breathing into the handle of the lamp provides the algae with CO2, whilst the side spout allows the addition of water and release of oxygen. Placing the lamp outside in the daylight, the algae use sunlight to synthesize foods from CO2 and water. A light sensor monitors the light intensity, only permitting the leeching of electrons when the lux level passes the threshold – avoiding algae malnourishment. Energy is subsequently stored in a battery ready to be called upon during hours of darkness. Owners of Latro are required to treat the algae like a pet – feeding and caring for the algae rewarding them with light.
