Little Green Cells

摘要

On an inner-city site in Hamburg, Germany, sits a building covered in algae. But this is no derelict structure: it is a bold experiment in harnessing one of the world's most primitive organisms to produce energy. The green micro-algae facade on the newly completed five-storey apartment block generates bio-mass and heat, supplying hot water for domestic use and heating the building. It is the first building of its kind in the world.
