Japan successfully tests deep sea turbine

Say goodbye to 'oil' and 'solar' power.
A deep sea turbine off the coast of eastern Japan has proven capable of producing almost as much energy as a coal plant.
Kairyu, a massive turbine prototype produced by Japanese machinery manufacturer IHI Corp, sits at least 100 feet underwater.
Its anchor line allows it to flex its position to most effectively harness energy from the Kuroshio Current—one of the strongest ocean currents in the world.
The machine sends all generated energy up a series of cables for use on the country’s power grid.

Kairyu, a massive turbine prototype produced by Japanese machinery manufacturer IHI Corp, sits at least 100 feet underwater. Its anchor line allows it to flex its position to most effectively harness energy from the Kuroshio Current—one of the strongest ocean currents in the world.

At first glance, Kairyu looks like an underwater jet. Its middle consists of a 66-foot fuselage, each side of which has a similarly-sized turbine cylinder attached. Both turbine cylinders contain power generators, control mechanisms, and measuring systems which correspond with their respective 36-foot turbine blades. The machine sends all generated energy up a series of cables for use on the country’s power grid.

        He is not, this will affect the natural currents that move cold water. This will be more destructive than coal if its implemented in regions with a strong underwater current

    Hopefully it doesn't fall apart when it comes time to do maintenance or replace parts. It's promising, but we'll have to see how it handles wear and tear.

      Well, plenty of us have seen wind turbines burn up, and they don’t have to deal with corrosive salt water, trash in the water, barnacles, etc.
      I’d like to see it work, but I’m skeptical.

    I'm sure that slowing down oceanic currents won't impact the planet as a whole in the slightest, just like wind turbines and partially reflective solar panels didn't. And I'm also sure that this is solution for everyone.

    >In Europe, the development of tidal flow power generation has been making progress and reached the commercialization phase. Meanwhile, Japan is located near the Kuroshio, one of the world’s most powerful ocean currents, and one estimate states that if the energy present in the Kuroshio could be harnessed, it would amount to approximately 205 GW, which is comparable to Japan’s total electric power generation.

    Who is going to maintain it, how will the grid handle it being shut down. How do natural phenomena affect it. I maintain coal power plants and and shit needs to be shut down every other year for a month for basic maintenance. I can imagine the nightmare of trying to maintain or repair these fucking things with such a specialized workforce that'll need to not only tradesman but master divers and underwater specialists.

    There's already a shortage of power plant workers and construction workers let alone introing something as crazy as this. Lefties I swear don't think about anything when it comes to logistics. All they see is

    >The mean flow speed of the Kuroshio is said to be 1 - 2 m/s (approximately 2 - 4 knots). Its flow speed varies depending on the water depth; in other words, water near the sea surface flows faster. Given this, an ocean current generator, installed near the sea surface, will be capable of generating power more efficiently. Nevertheless, waves caused by a typhoon might have a height of 20 m or more, and a higher level of safety is therefore required to install an ocean current generator near the sea surface. In consideration of this issue, we adopted the floating type ocean current generator, which is moored at a depth of around 50 m below sea level.

    >Kairyu was completed in July, 2017, and an open sea power generation demonstration was conducted in the Kuroshio off the coast of Kuchinoshima Island (Toshima Village, Kagoshima Prefecture) in August, 2017. In the demonstration experiment, we validated the floating type ocean current turbine in terms of workability and the power-generating performance and attitude control in the actual Kuroshio environment

    >As an approach to the commercialization of this technology, a floating type ocean current turbine capable of stably generating power is highly expected to serve as a low-cost energy source for remote islands, where
    power generation is forced to rely on internal-combustion power generators because it is difficult to receive electric power from the main islands of Japan via power cables.
