Pawel Rymsza's proposal to house humanity in a network of ring-shaped structures built around huge algae-rich lakes is the first of 15 visionary projects shortlisted for the Redesign the World competition powered by Twinmotion.

Called Carbon Neutral Rings, Rymsz's proposal is to create a network of enclosed carbon-neutral cities for humanity to live in.

Each ring is built around a huge reservoir of algae, which would be used to filter the air inside the rings and act as a carbon sink to absorb the city's emissions.

The carbon dioxide absorbed by reservoirs would ensure the cities are carbon-neutral initially and would become carbon-negative over time as humanity shifts to less carbon-intensive technologies.

Redesign the World is the ultimate design competition, which called for new ideas to rethink planet Earth to ensure that it remains habitable long into the future.

Launched in partnership with Epic Games, the contest asked entrants to visualise their concepts using architectural visualisation software Twinmotion.
