Japanese Underwater City Could Fit 5000 People And Draw Energy From The Seabed

Underwater city could fit 5,000 people and draw energy from the seabed

Japanese construction firm Shimizu Corp just revealed its new project: An underwater city capable of fitting 5000 people and draw its energy from the seabed. Shimizu says the project would take five years to build and the technology required would be ready in 15 years.

The structure is divided in three sections: A sphere — just behind the surface of the sea — with a diameter of 500m will house residential zones, business and hotels. A pod connected to a 15km long spiral that descends to the earth factory, located on the seabed.

Shimizu hopes this eco-friendly underwater city would attract funds from the Japanese government and private investors. The Guardian writes:

The factory will use micro-organisms to turn carbon dioxide into methane, while power generators located along the ocean spiral will use differences in seawater temperatures to create additional energy — a process known as ocean thermal energy conversion. Desalinated water produced using hydraulic pressure will be pumped into the residential pod.

    Lucky Japan isn't in an active seismic zone.

      Depending how the whole thing is connected and held in place it might not matter if the seabed shakes or shifts or even if there's a tsunami. It's certainly a question that needs to be asked though.

    As nice as it would be to see this thing happen, it's too complicated, too expensive, and too far ahead of is time to make it to fruition..! Projects like this, have popped up all the time over the years, how many have actually been built..? I'll be happy to eat crow, however..! :)

      Better off using zeppelin technology to build flying villages. Still waiting on that jetpack civilization.

      It would be far cheaper and easier to reclaim land from the ocean and build on that.

    This looks like final year uni student's dream project and will most likely not come to pass.

    Shimizu's Wikipedia page reads interestingly, showing a number of these "Dream Megaproject Concepts", including:

    Lunar Solar Power Generation
    The Environmental Island -Green Float
    The "Pyramid City in the Air" Concept
    Inter Cell City
    Space Hotel -Space Tourism
    Lunar Bases -Construction on The Moon
    Urban Geo-Grid Plan
    Desert Aqua-Net Plan

    It's great to dream.. fall amongst the stars blah blah (and they really are shooting for the moon in a couple of those!).

    One of the impressive completed projects:

    Throw in some art deco styling and you've got BioShock's "Rapture".

    I love the idea, but yet to see anything be made. Things like with have been designed since the 50s

    But But .......Godzilla!!!
