Algae and robots can combine to reduce CO2 in our oceans.
A New York-based research team is deploying algae-like bacteria’s photosynthesis capabilities to lower carbon dioxide levels indoors. A cyanobacteria-infused anode is embedded in a bio-based solar cell.
Five of these solar cells are attached as leaves to an artificial plant structure which is placed in a pot. Capillary action brings water and nutrients to the leaves from the pot, imitating natural processes.
Indoor light in turn activates photosynthesis, reducing carbon dioxide by 90% and converting it to oxygen. At the same time, the solar cells generate 140 microwatts.
Atmospheric humidity, however, can have a conductive effect on silkworm membranes, while loudspeakers serve as air purifiers.
