Disadvantages:-
Very low bang-for-the-buck return. If you want to use the natural flow of water to produce electricity with minimal environmental impact, it is better to stay with simple, off the shelf technology. For instance, a system using captured tidal water and driving a turbines is much simpler, and needs only a few valves to regulate the prime mover (water)
Advantages:-
Piezoelectric materials have the property of being able to extract electricity from movements, sounds and vibrations. The mechanism for this is that the materials have charges separated in a symmetric crystal structure; and when subjected to mechanical stress, a charge asymmetry arises that gives rise to voltage.
With piezoelectric flooring and pavement coatings that can extract electricity from waste energy from those who go on them. Trial installations on a small scale are already being tested worldwide. Integrated in environments such as railway stations, and other places where large crowds are moving, they may provide significant contributions to the local electricity supply.
