Abstract: Embodiments of methods and/or systems for sorting digital information are disclosed. In one particular embodiment, samples of a portion of digital information are associated with prime numerals. Such digital information may then be sorted based upon combinations of such digital information. In another example embodiment, a portion or sub-portion of a collection of digital information is converted to at least one sorting value. It should be understood, however, that these are merely example implementations and that claimed subject matter is not limited in this respect.

Abstract: A multi-stage refrigerant driven turbine is incorporated into a closed loop system to generate electricity. Heat transfer conduits and optional flow diverting members are disposed between the rotor blades of each stage of the turbine. The closed loop system also includes a condenser, pump, refrigerant storage container, refrigerant, and expansion valve. A heat source and heat sink are also provided. The expansion valve introduces a saturated refrigerant mist into the turbine, and the refrigerant expands as it flashes to a gas, thereby rotating the rotor blades and turbine shaft. Heat from the heat source is added between stages to increase the portion of refrigerant converted to gas. The gas is passed from the turbine, condensed, and passed as a liquid to storage or to repeat the cycle. The blending of refrigeration cycle and turbine technologies allows electricity to be generated in a closed loop system under moderate conditions.
