In his (fictional!) documentary, designer and artist Tobias Revell sketches the city of New Mumbai powered by giant mushrooms. These genetically-engineered fungal organisms provide a new type of infrastructure - providing heat, light and building material.
The documentary shows how the mushrooms grow quickly and begin to harvest the sun, creating energy that provides heat and lighting, like an organic solar panel. They can even be engineered to power a whole building. Some grow strong enough to be used as shelter, parts of building structures, and surfaces to grow local crops.
The mushrooms’ benefits expand even further as the clever residents of the Dharavi Mumbai slums discover new features. Their porous surfaces also absorb water from the seasonal downpours, which can be collected and used for drinking and bathing.
