• Underwater turbines, a better way to catch the tide and generate renewable energy

    In the future, we’re pretty sure it’ll just be the beavers building dams, with the world slowly turning towards more efficient ways to generate electricity from tide. And researchers these days seem to be playing around with the idea of setting up underwater turbines too, which is a pretty feasible way to suck all that renewable energy out of the tide. However, this does face a bunch of hurdles, given that water is about 832 times denser than air that makes life hell for underwater turbines, combined with corrosion, stray electromagnetic fields, and rules to safeguard sealife.


    And what better place resides than the depth of a river to set these turbines up! So, cities like New York and Sydney with water bodies around could do very well by generating electricity from underwater turbines like these.
