Hydroponics should be getting priority... otherwise it would be called aridponics. ;)<br/><br/>On a more serious note, Hydroponics should get first use of water, and probably has a supply devoted to it to humidify the air to a limited extent, keep the soil moist, water the seedlings and so on. The water will eventually be reclaimed either by consuming the plantlife or recycling the used water into the main tanks... but without water, the plants won't grow and everyone starves.<br/><br/>In my own mind (Chrystal may have different concepts)water reclamation would include a system to partially remove moisture from the air, reclaiming sweat from clothing,recycling water waste and used water. We already know that water is recycled via a highly efficient filtration system but every time we breath out, we pass a small amount of moisture into the air (How the sinuses stay moist) and clothing collect it via perspiration, and will eventually enter the air supply as it's dried.<br/><br/>Anyway, just my own thoughts.
