| 20080237025 | CLOSE-COUPLED VAPOR-COMPRESSION DISTILLER - A distiller that employs a rotary heat exchanger uses a centrifugal compressor to impose a pressure difference between the distiller's evaporation and condensation chambers. The compressor's diffuser is provided on the rotary heat exchanger to rotate with it, and the force applied to the diffuser by the vapor that the diffuser slows helps drive the rotary heat exchanger's rotation. Additionally, the compressor is so closely coupled to the heat exchanger that the vapor speed at the condensation chamber's entrance is at least an eighth of the peak vapor speed in the compressor, and the entrance area can therefore be small enough to simplify the task of sealing it. | 10-02-2008 |

| 20090134004 | Driving or driven distiller with heat pump function - This invention improves efficiencies of existing distilling devices and provides the opportunity to utilize latent heat for heating or cooling purposes. Sufficient heat sources or cooling sinks can drive the invention for mechanical power production. The innovative use of an elongated chamber hydraulic column positive pressure at the bottom to drive condensation; and pertaining negative pressure in a sealed volume at the top to evince evaporation give a new capability. Repeated mechanical inversions of the chamber allows the evaporated vapor volumes to be compressed and driven to condense by the fluid hydraulic column as a piston, eliminating requirements for seals. This allows operation with many fluid separations and in many physical environmental regimes, both internal to the elongated chamber and externally. Inverting the chamber uses or produces power efficiently in force fields such as gravity, centrifugal, or linear inertial yielding possibilities for miniaturization and extension of output parameters and throughputs. | 05-28-2009 |
