1. A desalination assembly comprising:
a first module comprising:
a first vessel having a first portion and a second portion separated by a hydrophobic membrane operationally connected therebetween and oriented to pass water from the first portion to the second portion;
an air blocking layer adjacent the hydrophobic membrane and disposed in the first portion;
a vacuum gap adjacent the hydrophobic membrane and disposed in the second portion;
a first fluid inlet and a first fluid outlet operationally connected to the first portion; and
a second fluid inlet and a second fluid outlet operationally connected to the second portion;
a second module comprising:
a pump having a pump outlet and a pump inlet operationally connected to a water line and to the vacuum gap;
a linear Fresnel mirror collector for collecting and focusing sunlight;
an outlet line operationally connected to the pump outlet and positioned to receive focused sunlight from the linear Fresnel mirror collector;
a third module further comprising:
an ejector having an ejector inlet portion and an ejector outlet portion, wherein the ejector inlet portion is operationally connected to the outlet line and to the vacuum gap;
a second vessel fluidically connected to the ejector outlet portion comprising:
a heat exchanger operationally connected to the ejector outlet portion and to the water line;
a feed spray operationally connected to the second fluid outlet and positioned to spray into the heat exchanger;
a collection portion for receiving concentrated feed spray; and
a degasser operationally connected to the second portion and to the feed spray;
wherein the heat exchanger receives desalinated water from the ejector and from the feed spray;
wherein the water line carries desalinated water from the heat exchanger;
wherein the first fluid outlet passes concentrated brine; and
wherein the first fluid inlet receives feed water to be desalinated.
