In Japan, officials decided to launch an initiative called Next Tokyo, where architects would create a futuristic mega-city that is adapted to climate change in the year 2045. Kohn Pedersen Fox Associates and Leslie E. Robertson Associates joined forces to propose a vision for a new city in Tokyo Bay. Their design incorporates elements that improve the bays preparedness for natural disasters (such as earthquakes and typhoons) as well as a mile-high residential tower and a public-transportation-friendly district. The water developments hexagonal-shaped structures, ranging from 500 to 5,000 feet in width, were imagined in layers to minimize the effects of intense waves from the bay, while also allowing ships easy access in and out of the busy harbor.
Whats more, some structures would be prefilled with water, allowing access to islands that are public beach harbors and urban farming plots. Salt water from the bay would also be retained to grow algae, a source of renewable and clean fuel.
