Commercially, though, you have a lot of costs to recover from the construction of one of these. You have to pay workers, u like a kid who makes one for a class. So, even though the energy is free, converting it to electricity may not be cost effective. I read about these wave things in the 1970s, and the cost was too high then. I wondered if that would change over time, especially as petroleum got more expensive.
