Oceanix says the project “takes into character the social, political, environmental, and economic aspects of South Korea. This will be informed by Busan’s unique juxtaposition of old and new, a port-city rich with culture, art, and trade.”

The city will generate all of its own power using solar panels located on rooftops and floating on the sea. It will have a zero-waste economy, only allow electric vehicles, and treat and replenish its own water.

An Oceanix cofounder previously told Insider that the city could cost around $200 million to build and that the first parts could be ready by as early as 2025. Oceanix revealed the new designs ahead of the Second UN Roundtable on Sustainable Floating Cities, which is being held in New York on Tuesday.

The UN added that floating cities “give us a clean slate to design climate-neutral cities from the start.” They can also be towed to bring resources to areas of need during humanitarian crises, the UN said.
