The best way to ask this question is through visualization. Imagine a funnel with a hose sealed to the spout. Then imagine that you are at the beach holding the end of the hose above your head. The hose goes straight down from your hand into the sand at your feet to a depth of three feet underground, then turns out to the ocean and stays three feet underground all the way to where the ocean depth is thirty feet. There the hose comes up from the sandy bottom and opens into the funnel. How big would the funnel have to be to make salt water come spraying out of the end of the hose with enough force to drive an electric generating turbine?
