Ok, now there is a few more problems. One, how much water do you think these pipes are going to be able to move and at what rate? Do you think that these tubes will 'pump' enough water to cause a significant change in temp? Since you obviously do, please post some numbers so that they can be verified. There is a lot of water moving and mixing from the Keys up the East Coast, its going to take A LOT of cool water to lower its temperature significantly.

Next, how will these electrical generator pumps create power if there is no water flowing through during the times that they are not operating? You say because they are close to the surface, but that doesn't explain where the generated electricity comes from. Please elaborate more.

I think this is intriguing, so please, continue with your ideas.
