(building more units is trivial scaling). What I mean is that there is no return to scale benefits per unit that would bring down the cost per unit. Wave size

(building more units is trivial scaling). What I mean is that there is no return to scale benefits per unit that would bring down the cost per unit. Wave size and wavelength puts limit to energy that can be extracted from single unit. Material costs, including the copper for power lines _per_unit_ determine the price. Unless you can ramp up the energy per unit massively, the concept is not competitive with wind power. Wind turbines at sea can do 10-15 MW per unit today and 22MW turbines are coming. If you want to prove me wrong, show us cost per megawatt calculations. For wind turbines the cost is roughly US$1.3 million per megawatt (MW) and maintenance is 1-2 cents per kilowatt-hour produced.
