Can we use this idea of harnessing the ocean wave energy for rivers as well?

It is a nano generator that gives 8 microwatts each. On a sufficiently large scale, if efficiency turns out to be fair enough, we may not even need the turbines. What do you think about it?
That's what this article is about. River, creek and stream turbines. It does not discuss oceanic power.
