The ocean is a very large place, and much of the floor is nearly barren of life (compared to coastal waters anyway, and certainly in terms of biomass). Furthermore benthic storms already cause a great deal of turbulence on the bottom; i don't think problems are obvious. Granted, i have similar concerns about efficiency, but we need any wins we can find.
