||apart from not really wanting salt inland, how are you going to "filter out the salt with gravity" ?
||By using the pressure differential generated by a 1/2 mile column of water to drive reverse osmosis, silly.
||I thought that a filter membrane with air on the
other side, would not be "reverse osmosis". It seems
the claim is that it is. So I'm editing this idea to
remove that part.
||Well now thats just silly. Why pump all that saline uphill instead of distilling it at the source? You are just doing the work twice.
||because pumping the saltwater is not twice the
work of pumping freshwater, but rather
1.000000000000001 more work. And its easier to
find locations inland for doing the work, especially
if the reservoir is already high up (usually above
the cities or at close height).
||Last but not least, using dewVaporation
technology and the likes of it, makes no difference
where you do it, so you are not doubling the
work, only doing it once. And probably with a solar
solution, its probably easier to get the water to
evaporate in daytime (hotter temperatures and
drier air) and then to cool at nighttime (colder
temperatures at night) when your further from the

my country is one the three richest people here.
And all because his grandfather was first to think
of of it. Just to show that there definitely is a
request for salt inland...
