    so, we are all aware that we don't feel any weight or thrust (which act upon us on land) when we are under water..! and we are also aware that the turbine blades(which produce electricity by rotation) are very very heavy...! so when they're allowed to rotate under water don't they rotate with greater efficiency?? doesn't that lead to increased power production?? My idea may be completely flawed..! it's rather just a doubt of mine...!.! Help me...!

    The weight of turbine blades has nothing much to do with the efficiency of the turbine. For example a turbine for an aerospace application may have to be light to reduce dead weight. Cost is of less importance. So Titanium is a preferred metal. But a turbine on land can be of a material that gives longer trouble free life. Overall cost is important. Super alloys are commonly used.

    less input and more output is best right..! so if the turbines rotates with very high velocity with minimal input..! power production is increased..! is it not?? sir..!

    overall cost eh?? oh thank you sir...!!! yes each and every factor must be looked into..! i seldom think bout tht..!

    less input more output!
    it is not possible

    He is not talking about more than unity efficiency, only higher efficiency less than 100%.
