#1 How many places does "clean, fresh water" flow into the sea? Most rivers I've seen are chock-full of sediment. I would think the membranes would get clogged up pretty quickly.

#2 The problem with sea water for anything is always "biologicals", and filtering them out is an expensive process.

Instead of using membranes for energy, it makes a lot more sense to use them for water purification. They are now making a carbon nanotube filter that will only pass individual molecules of water.

One very simple system that could do this at scale is a double pipeline device, a pipeline within a pipeline. On the ocean floor, next to a coastline, a large storage tank is put in a low-lying area. Leading out from the tank are one or more double pipelines.

The outer pipeline is a big filter that separates out just the water from the sea water. The second inner pipeline does the same, double filtration, in case something penetrates the outer pipeline. Then the fresh water inside the second pipeline flows "downhill" to the tank.

From the tank, fresh water is pumped out to shore.

The only energy used is pumping the fresh water out of the tank. The water pressure on the pipelines do the rest.

#3 How many places does "clean, fresh water" flow into the sea?thye entire west coast of Canada, and All of Alaska.

#4 Is it just me, or does anyone else get the feeling these small or minor "green" = environ correct ENFACS are SUB-PLANST/FACS OF SOMETHING IN OWG-NWO "JUNKERS GLOB GRUPPE" LARGER SCALE, SOMETHING NOT SO "GREEN"???

#5 Not just you, JosephM. Because mostly these things are not self-supporting, which means the money has to come from someone else's pocket. The approach is thought globally and applied locally.

#6 5 million sq meters of fish net? Sure,that sounds environmentally responsible.
