A "live" lamp Microalgae Lamp absorbs CO2 from the air

French biochemist Pierre Calleja has developed udivitelnoe eco-friendly lamp that could light up streets and Parking, while reducing CO2 emissions. The device is not dependent on electricity and is fed exclusively through a tube filled with glowing green algae. The lamp uses the energy produced by photosynthesis in the cells of the algae, while the algae live at the expense of CO2 obtained from the air.


The lamp is designed in such a way that it can store the energy obtained from photosynthesis for later use. Thus, when the lamp falls in conditions of low light, it can glow without the need of any external power source. One lamp can absorb approximately a ton of carbon out of the air just one year or as much carbon dioxide as absorb during the same period, 150 or 200 trees. If these lamps became widespread, it could contribute to combating climate change and reducing air pollution.


It is interesting to note that the lamp is not the only application of microalgae, proposed by biochemist Pierre Calleja. He and his team at FermentAlg are already using microalgae as a sustainable source of omega-3 or base for natural cosmetics. They also figured out how to use algae as source of biofuels. published
