A compelling urban canopy designed by EcoLogics Studio boasts bioreactors able to create a forest’s worth of oxygen daily (the equivalent of 400,000 square feet of natural woodlands). In that same short time span, the system can also produce hundreds of pounds of biomass by growing green microalgae that can be turned into bio-fuel. A prototype module of this BioCanopy design
