i wonder how they are going to address the issue of marine fouling. (barnacles, etc.)
also, there is a math problem:
“Each turbine is a weighty piece of mechanical engineering, measuring 15 meters tall and weighing 200 metric tons, with eight-meter-long blades.”
if the blades are eight meters how do they turn in a fifteen meter circle. even with no allowance for a hub, it would require sixteen meters. maybe they’re using common core math. god help them.
