  •  What about tapping into the (none)
    deep sea water conveyers that keep the Northern Hemispheres weather temperate?

    There are underwater rivers of current in the North Atlantic which are in constant motion... any ideas or projects exploring tapping those for electricity generation?

    •  you are talking about huge engineering projects. (none)
      These gyres are surface currents, such as the North Atlantic Current. There are "surface" in the sense tht they are not deep "bathyal" water masses. they are less dense than cold water and transfer the heat of the equatorial region to northern climes.

      The deep currents you are thinking of are cold water masses generated by the arctic and Antartic ice sheets. As water freezes, Salt content increases and the colder water becomes denser and sinks travelling towards the equator.

      This water has been dated at 5-10,000 years old based on C14 isotopes, in some places, It is not moving that quickly.

      The top of the water column moves faster. around the globe.  But again if you slow any large water mass you will alter the erosion and deposition patterns locally
