Algae-covered tower proposed for London

Algae tower

UK architect Dave Edwards has conceived an energy-harvesting tower in London that is covered in algae, reported dezeen.

Designed for a site in the City of London’s Square Mile, the conceptual mixed-use tower would produce its own energy and clean water.

An outer ‘green wall’ of algae would absorb CO2 emissions and harvest bio-methane for conversion into heat and power.


The building’s skin would be fed by waste biomass while waste water would be recycled through the algae.

The skin would also grow plants that would yield food for the inhabitants of the tower.

A ground source heat pump would store summer heat and enable surplus heat from the waste biomass to be circulated through the tower in the winter.
