French Biochemist Designs Algae-Powered, CO2-Absorbing Lamp
What if fighting global warming were as simple as flipping a switch and turning on the lights? This may soon be a reality. French biochemist Pierre Calleja has designed a CO2-absorbing streetlamp. Powered by microalgae, the lamp could absorb as much as a ton of carbon from the air every year. That’s the same amount absorbed by 150-200 trees.
Calleja’s lamp consists of a lighted aquarium filled with CO2-eating algae, which draw the greenhouse gas from the air — even in dark or closed environments like an underground parking garage. Even though the lamp has been installed in a few places, they’re not ready for mass production yet. Apparently, part of the problem has simply been obtaining funding for the project – Calleja says that many of his partners have been reluctant to commit much money to this experimental technology.
In the following video, Calleja explains how the lamp works and his hopes for the future. You’ll also get to see the lamp in action:
What do Care2 readers think — if these were to become widely available, would you install a carbon-munching algae-lamp in your home?
