Algae lamps collect 150-200 times more CO2 in a year than trees
Algae are a large, diverse group of simple microorganisms that have lived on Earth for billions of years. Although we typically associate the term algae with the slimy green stuff that accumulates on the surface of a stagnant pond, seaweed and kelp are also member of the algae family. In the right situations, algae can be very useful to humans, and their potential as an energy source has received lots of attention over the past few years.
French biochemist Pierre Calleja is now looking at algae as a potential source for helping clean the air of carbon dioxide. He has spent several years developing what looks to be an interesting street lamp that feeds on the vast amount of C02 swirling around in our atmosphere.
There’s no denying that the street lights are cool, and if they became a regular fixture in densely populated cities – and are actually viable – they could have a massive impact air pollution in urban areas where trees are scarce. More research is needed but this is an interesting possibility.
