The building is to serve as a test case and will be studied by various architects and engineers from around the world to determine if the design is feasible and if so, to perhaps serve as a model when erecting buildings in other cities. Citation: First algae powered building goes up in Hamburg (2013, April 12) retrieved 18 August 2019 from https://phys.org/news/2013-04-algae-powered-hamburg.html To make use of the algae, which the team retrieved from the nearby Elbe river, it was put into large thin rectangular clear cases. Inside, the algae live in a water solution and are provided nutrients and carbon dioxide by an automated system. Each tank was then affixed to the outside walls of the building onto scaffolding that allows for turning the tanks towards the sun—similar to technology used for solar collectors.
