Abstract: The earth consists mainly of water and water exists on the earth's surface, in aquifers in the soil as groundwater, and in the atmosphere as water vapour. However, of all the water on earth, only less than 3 percent is fresh water. Due to factors such as climate changes, environmental pollution, as well as population growth, the available amount of fresh water sources is dwindling rapidly. In addition, there are many problems associated with provision of potable water using existing techniques. One way to overcome the aforementioned problems is to extract water from the atmosphere. However, hardware costs of current commercial systems are relatively high and they are not efficient in terms of performance. An embodiment of the invention provides a system and a method for obtaining potable water by extracting atmospheric water.

Abstract: Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle. More condensate is recovered from the low enthalpy vapor in the condenser.
