The low-energy water reclamation process consists of evaporation from water sources, followed by capturing, condensing and reusing the water released into the atmosphere from both the evaporation process and by plant transpiration. 95% to 99% of water from plant transpiration is lost by venting to the atmosphere. We capture that water, and reuse it, to grow food or provide potable water. Reclaiming and reusing the evaporated water reduces both the amount of new water required for plant growth or potable water production, and also reduces the total energy requirement for the process. Over a large growing area, we expect to reclaim a significant amount of transpired water, which will reduce the need for new water to grow food and/or provide pure unpolluted potable water, at lower total cost.
