One thing I have realized is that data that was achieved to simulate conditions on Mars suggests a rate of 10L/hr per square meter. While that may not seem like much, that is with water, air and surface temperatures at 0C. Here on planet Earth and with a water temperature about 24.4C, a vacuum of 29 hg's would be needed. And because of the greater temperature variation possible between evaporated and condensed water, a much more favorable rate should be possible. This is something I plan on pursuing in the near future. It is as the scientists who did the Mars study stated, there is little data on the evaporation rate of water under vacuum. This is something I hope to make better understood. There is one give away with pressure heads and vacuum. When vacuum nears 29 hg's (28.67), the boiling point of water lowers less as the vacuum is increased. This would be because the atmospheric gasses are becoming stretched. This would require a pressure head taller than 9.8 meters to have sufficient force to expand atmospheric gasses beyond their normal state and achieve an extreme vacuum. And if such an idea works well, the water moving through such a system would require little energy as the brine and fresh water discharges would help to ensure that sea water is drawn into the system by the vacuum desalinizing the water. Simply put, the 2 discharges would be siphoning water into the system as they drain.
