The Pyramid could be a good AWE plan for offshore installations. Its possible limitations in altitude, comparable to that of regular wind turbines (HAWT), would not be an obstacle. Indeed, the wind gradient is lower in the open sea, which leads to lower gains by gaining altitude. And the advantages compared to HAWT would be: less mass as expected, less concreting, less destruction of the marine environment, more easily accessible generator… And compared to other AWES: less length of rope obstructing the maritime traffic…
