Carbon sequestration is merely a side effect, the main goal is to have a wavebreaker and a park and a place to grow fruits, for a floating city. To bring nutrient rich water up and to generate energy in the process temperature difference between surface and deep water can be used [1]. So if this kind of tree is created, living on open sea can become cheaper and more pleasant than even living on a beach.
