Ja.  What I meant was I have a compressor in my garage that goes to 120 psi,
twice four bars.  We could put together a short piece of pipe and use
compressed air to give that little bit of pressure differential without tall
buildings, boats or pipe.

contacted and asked how they acquired or made that membrane?

I haven't seen any details anywhere, or any suggestion for how graphene
could somehow overcome the 27 bar osmotic pressure of seawater to fresh.
The takeaway is that we need to beware of the claims being made for
graphene.  It is really cool stuff, but it can't do magic.
