Next question- How many million was spent on this small scale project and what is the cost per KWh?
Renewables are great that they don't pollute but if they cost too much, they won't advance very far.
The big advantage of this system is that the waves never stop...unless you've got a hurricane coming in, and then the whole system is destroyed.

I think that in terms of costs, this system is suitable to small scale projects. It is part of a solution, not a global solution.
