Algae Skyscraper

Concept, 2009

The reduction of carbon dioxide is the most urgent target for the survival of our earth climate. It will need buildings in the future which not only produce their own energy, but also reduce the CO2 significantly. So why can’t we build skyscrapers like trees? Trees use CO2 for their photosynthesis and produce oxygen and energy.
This apartment skyscraper (32

floors) would use algae bioreactor tubes attached to the facade to produce energy and reduce the CO2 in the air while producing fresh CO2. Living in such a building would totally offset our individual global footprint and provide all necessary energy for the inhabitants. A high-tech 'tree' for dense cities, but 10 times more environmental effective.
