Nope, miss it. My bad ;-)

Fair enough.

I think that this depends on how much this system can really “produce”.

True. And I did just recently learn that power prices per kWh in California are about double what I'm used to here in Texas, so maybe it's more viable in that market. This just seems like a more complicated, more involved, more demanding version of pumping water into/out of a reservoir on a hill which we already have several examples of that are working great (there are more in the UK) without requiring complex and expensive maintenance and without subjecting pumps and turbines to highly corrosive salt water. I guess pressure in the ocean is easier to come by than hills big enough to create reservoirs on, but..
