Water Scarcity in Southern Africa

MicroEmpowering

The world’s first building powered by algae has been unveiled at the International Building Exhibition in Hamburg by engineering firm Arup. The “bioreactor façade” has been mounted as a kind of “second skin” onto the sun-facing sides of the BIQ building. The panels — which are more like tanks — contain algae that grows in the direct sunlight. It can then be harvested and turned into a biofuel-like pulp that is burned in a generator at the heart of the building.

The algae feeds on carbon dioxide and nutrients that are supplied via a water pump, and further energy is also harvested by solar panels, with energy stored for later use in 80m deep boreholes filled with brine. The whole building is intended to be completely self-sufficient. As pleasant side effect is that the algae panels — each just over 8′ by 2′ in size, with a total surface area of 2152 square feet — also provide shade for the building’s occupants (via Hamburg Unveils World’s First Algae-Powered Building | Wired Design | Wired.com)
