Microalgae Lamp Absorbs CO2

This Microalgae Lamp Absorbs

150 Yimes More CO2 than a Tree!

The Wonders of Microalgae

Based just outside of Bordeaux, France, biotech Fermentalg is designing a groundbreaking street lamp that absorbs enormous amounts of CO2, over 150-200 times more than a tree – using microalgae.

French biochemist Pierre Calleja founded Fermentalg in 2009 to exploit the wonders of microalgae for many applications from fuel to health to the fishing industry. The microalgae street lamp is a tube-shaped tank filled with green algae. Each street lamp absorbs 1 ton of CO2 per year, more than 150-200 times more than a tree. 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. Moreover, the lighting structure of the lamp operates on a battery that charges during the day by “microalgal photosynthesis”. The algae street lamp was recently tested in a parking lot in Bordeaux.

Pierre Calleja has invented something truly remarkable--a light powered by algae that absorbs CO2 in the air--at the rate of 1 ton PER YEAR, or what a tree absorbs over its entire lifetime! The microalgae streetlamp has the potential to provide significantly cleaner air in urban areas and revolutionize the cityscape.

To Clean the Air off its CO2 Content

According to French biochemist, Pierre Calleja, microalgae are potentially quite useful in furthering man’s efforts to reduce CO2 emissions from the atmosphere. Man created cars, build roads and now he is responsible for all the pollution that envelops the earth. He is endlessly struggling to restore the imbalance he created, but does not always think innovatively. Pierre definitely gave up conventional thinking and vested faith in the power of microalgae, which can absorb immense amounts of CO2 from the atmosphere.

What Pierre created is the microalgae lamps or CO2 absorbing lamps to be placed along highways and streets and eventually to be installed in office premises and even at homes. These large scale street lamps will absorb around one ton of carbon dioxide emissions per year. Factually, 25 percent of the carbon dioxide present is air is contributed by car exhaust and placing them along streets is thus logical.

During the day, batteries installed inside the lamp will be charged through the process of photosynthesis, using both sunlight and nutrients. At night this stored power will be used for lighting. It is not always essential for the lamp to work in the presence of sunlight, when placed underground or any other place where the sun does not shine bright or there is no source of natural light, it will absorb CO2 and then power itself.

Explicitly this lamp is used for lighting and gets charged on its own, which is definitely beneficial, but what makes it even more useful and environmentally friendly is its CO2 absorbing capacity, which is greater than that of many trees put together, Therefore, we can presume that if successful, their installations across cities will be an efficient replacement for the trees cut down to make way for urban development.

Algae Street Lamps Suck Up C02

But How Exactly?

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 The lamps are really more like massive tanks filled with water and algae. As you can see from the video below, the lamps, making use of a lighted environment, work with the added micro-algae to scrub out the C02 in the air. What’s not exactly clear is how this process works. There are certainly examples out there of micro-algae being bred specifically to absorb carbon emissions (you can even try building this one if you have the DIY skills), but whether that includes this pet project of Calleja is unknown. Perhaps it involves a carbon sink making use of photosynthesis?.

بالصــــور والفيديــو : إنارة الشوارع بإستخدام الطحالب

بعد أبحاث دامت طويلاً توصل الكيميائي الفرنسي بييرا كاليجا إلى طريقة مبتكرة لإنارة الطرقات تعتمد على التمثيل الضوئي. المصابيح عبارة عن خزانات مملوءة مياه وتحتوي على طحالب تعمل على تحويل ثاني أوكسيد الكربون وأشعة الشمس إلى طاقة تخزن في بطاريات، والتي بدورها تعمل ليلاً على توهج المصابيح باللون الأخضر. طن واحد في السنة هو معدل امتصاص الطحالب لغازات co2، وهو ما يعادل امتصاص شجرة خلال فترة حياتها كلها، مما يساعد على توفير هواء نظيف في المدن الملوثة، وذلك مما يجعل المصباح صديقاً للبيئة. وتشاهدون مزيداً من التفاصيل في هذا الفيديو
