1. A water purification system comprising:
a) a membrane separator comprising:
i) an ionomer membrane having a water source side and a condenser side;
ii) a condenser having a condenser surface and an opposing latent heat surface;
iii) condenser chamber formed between the ionomer membrane and the condenser;
iv) a separator enclosure that forms a separator tube having an interior side and an exterior side and wherein the ionomer membrane forms a tube configured within the interior side of said separator tube;
wherein source water at a first temperature is configured on the water source side of the ionomer membrane;
wherein the condenser chamber is maintained at a second temperature that is below the first temperature; and
wherein water is drawn through the ionomer membrane from the source water to the condenser chamber where it condenses on the condenser to form purified water;
b) a latent heat loop comprising:
a latent heat chamber comprising:
a latent heat inlet; and
a latent heat outlet;
wherein said latent heat chamber extends along the latent heat surface of the condenser and is configured on an opposite side the condenser from the condenser chamber;
a flow of said source water into said latent heat loop over the latent heat surface of the condenser in said latent heat chamber;
wherein said flow of source water increases in temperature from said latent heat inlet to said latent heat outlet;
a conduit extending from the latent heat chamber outlet to the water source side of the ionomer membrane; and
a conduit extending from the latent heat chamber inlet to the water source side of the ionomer membrane;
wherein source water flows from the water source side of the ionomer membrane, to the latent heat chamber inlet, to the latent heat chamber outlet, and back to the water source side of the ionomer membrane;
c) a purified water outlet from the condenser chamber.
