Hi @jeffjagoe,
I don't think we would be able to cover the entire ocean surface with solar panels, for many reasons such as: the amount of material would be needed. It is possible and desirable that some not tourist cities will do it. With the hope that they are not going to impact too much on the local environment. However, studing a bit each specific case, I am sure we can find a solution for them to coexist: energy production and natural beauty.
