Free Light, Fresh Air: The Guarantee of French Algae Lamps

Okay, right here’s a puzzle: What kind of light creates its own power, transforms co2 (CO2) right into oxygen, has no on/off button, and functions 1 day a day?

An algae lamp, certainly! While you will not discover these at your local illumination store anytime quickly, the cutting-edge algae lights invented by French biochemist Pierre Calleja have the possible to assist purify our atmosphere and conserve huge quantities of electricity … by developing their own.

Right here’s just how they function: The lights are generally huge clear tanks filled with water, algae, a light, as well as a chargeable battery. Particular kinds of algae– Calleja claims they’re among “guy’s friends”– can feed off the sun’s power and/or organic carbon.

Inside the lamp, the algae break down CARBON DIOXIDE into oxygen molecules as well as carb energy. They use that energy to produce power, which is stored in the battery as well as can sustain the light even when the sun isn’t out. So the light is cost-free, and also even better– the oxygen produced by the algae returns to the atmosphere.

Below’s why that is very important: CO2, a really typical byproduct of human activity, is among the greenhouse gases that contributes to environment change. Trees and other plants convert CARBON DIOXIDE into oxygen and energy, however as humans turn green areas like forests right into locations for buildings, agriculture, as well as mines, we lose the trees and also their oxygenating impacts, which accelerates the so-called greenhouse effect of atmospheric warming.

A microbiologist for two decades, Calleja states that of his lights, lately installed in a below ground parking garage in Bordeaux, France, can catch and also filter literally a ton of CARBON DIOXIDE a year. This light represents the beginning of his dream: He ‘d like to see his algae lights mounted not simply in garages, however additionally in houses and also along roadways, where they might cleanse the exhaust straight from autos’ tailpipes.
