Paris! The city of light or love !. Whether we call it one way or another usually depends on what our sentimental state is at the moment, but the truth is that its lighting It is one of the most beautiful in the world, although it could even improve with luminous bacteria on the streets.
The Eiffel Tower, the Louvre, the Arc de Triomphe and even the most filthy house; all the buildings and monuments in Paris are beautiful at night, thanks to that endless number of light bulbs that make your area view a real delight. But you have stopped to think about economic and energy expenditure what does that suppose? I know the French must have thought so 2013 a was approved law that prohibits offices and retailers from keeping their windows on during first hours of the morning.
For this reason, a company located in Paris has had the great idea of using the bioluminescence produced by some bacteriato replace the traditional lighting methods. This company is called Gloweeand they have already trusted their project, the funds of which were obtained in a campaign of Crowfunding, companies as important as the ice cream makers of Ben & Jerrys.
How do they obtain bioluminescence?
The bacteria proposed by Glowee, are obtained from a bioluminescent squid, typical of Hawaiian waters. To take advantage of their light, they use small ones transparent boxes, in which they introduce a gel which contains the live bacteria, beside sugars and oxygen they need to live.
Being totally bacteria harmless, would not pose any problem for the operators who handle them. In addition, they present other large advantage, As the energy saving and his low light intensity, sufficient to illuminate the pedestrians, without exceeding the limits of the light pollution.
Disadvantages of this type of luminous bacteria on the streets
Although you have already seen the great advantages of lighting with bacteria, it also has great drawbacks that must be resolved. First, the lighting would only last three days, so it will be necessary replenish periodically the gel. In addition, it is true that it involves energy savings, but it is not so clear that the production costs may become more profitable than in the usual methods.
Be that as it may, at Glowee they are ready to optimize this resource to the maximum. It is certainly a great idea that, in fact, would give a new charm to the city of Paris. Can you imagine something more beautiful than a marriage request in an Eiffel tower lit by bacteria?
