Plans for underwater Japanese city by 2030
With the population of the Earth growing by 200,000 every single day, the number of people inhabiting this planet by 2030 is estimated to be over 8.3 billion. For this reason, and with science and technology catching up to man's thirst for exploration, colonizing space is a reality and an endeavor that has already been started by government and private space programs. The Japanese government, besides looking above to outer space, is looking below at the depths of the ocean for future sustainability and survival.
Japanese construction firm Shimizu Construction announced that, with an anticipated budget of 3 trillion yen, or about 24 billion dollars, a total of 20 scientists and engineers from the Japan Agency for Marine-Earth Science and Technology, Tokyo University, Saga University, and Showa Denko have drawn up plans for the creation of an underwater city, named OCEAN SPIRAL. It will consist of a floating sphere near the surface of the water connected to a giant spiral structure that will reach a resource and research facility on the sea floor, all built to withstand the harsh underwater environment. The facility will be 3000 to 4000 meters below, at the bottom of the ocean, where rare metals are aplenty. Fish farming will help sustain this underwater city, where 5000 residents will be living in the sphere atop the spiral, along with businesses and hotels. Construction is slated to take five years, and completion is planned between 2030 and 2050.
In a statement, Shimizu Construction gave its reasons for taking on this huge endeavor. "70% of the planet is made up of water. For the survival of the human race, using the deep ocean is absolutely necessary." The technology will apparently be ready in 15 years.
No word yet on how Shimizu Corporation is going to get 3 trillion yen.
With hotels and businesses, the sphere will be an actual city
