From oxygen-producing facades, to farming in towers we look at four of the newest skyscraper technologies.
Man-Made Biological Leaf
A functioning man-made leaf that uses photosynthesis to absorb water and carbon dioxide to produce oxygen, just like natural leaves, has been created by Royal College of Art graduate Julian Melchiorri.
The leaf could transform life on Earth; buildings could be clad with the material to oxygenate homes and polluted urban
areas.
