Algae Lamp Absorbs Co2
French biochemist and shamengo pioneer pierre calleja has invented this impressive streetlight that is powered by algae which absorbs co2 from the air.
Algae lamp absorbs co2. We have featured algae powered lamps before. O a microalgae lamp can consume 1 ton co2 in just about 1 year where as a tree does it in its whole lifetime. In his ted talk the street lamp that absorbs co2 calleja explains how he created the light source and how his unique take on algae can help the world. Self powered microalgae street lamp absorbs co2 pierre calleja has developed a co2 absorbing self powered lamp for use as street lighting currently in prototype testing in france above image is.
A fascinating lamp design uses living algae to produce an electricity free glow and could absorb as much carbon as 200 trees a year. Each street lamp absorbs 1 ton of co2 per year more than 150 200 times more than a tree. O not only produces light but consumes co2. One study suggested the lamp can remove 150 200 times more of unit of carbon dioxide compared to a tree.
O produces light and cleans the air. As 25 of carbon emissions come from car exhaust placing these sci fi looking street lamps on roads and parking lots could have an enormous impact on co2 emissions. An innovative lamp powered by algae has the potential to absorb up to one tonne of co2 every year which is as much as a single tree absorbs over its entire lifetime. Researchers at fermentalg claim the lamp can remove 1 ton of carbon dioxide from the atmosphere per year which is ten times the approximate 0 10 tons of carbon dioxide sequestered by an ash tree in a year.
The lighting system requires no electricity but instead draws carbon dioxide from the atmosphere and produces an illuminating glow thanks to algae. Since the micro algae lamp utilizes the process of photosynthesis it absorbs carbon dioxide present in the atmosphere. Pierre calleja has been working with aquaculture technology since the early 1990s. His newest contribution to the world is a microalgae lamp that will absorb a ton of carbon from the air every year.
The microalgae street lamp is a tube shaped tank filled with green algae.
