Dive summary:

• At the International Building Exhibition in Hamburg, Germany, there is an experimental building that has tall, thin glass tanks on its sides, and they are home to algae that is fed carbon dioxide through a pipe network and thrives on sunlight to produce material that fuels a biogas plant to power the building.
