Abstract: Provided is a rotating energy conversion device that includes a heat absorber having a working fluid therein, a power converter in fluid communication with the heat absorber, and a heat rejecter in fluid communication with each one of the heat absorber and the power converter. The device may utilize an energy source that provides radiant energy to the heat absorber. The device may utilize a segmented energy source that may have a plurality of segments, wherein each segment may be either activated or deactivated to deliver the radiant energy to the heat absorber. The device may utilize waste heat produced by the device to create additional work. Furthermore, the device may utilize multiple thermodynamic cycles.

Abstract: Methods, devices, and systems, and devices for carrying out sorption (adsorption and absorption) for separating and/or purifying fluid mixtures are disclosed. Medical oxygen generators, dehumidifying units, sorptive heat pumps, ozone generators and Peltier devices are also disclosed. The sorption methods involve pressure swing operation of at least two sorption units. Energy from the desorbing and decompressing fluid is substantially recovered and used within the system.

Abstract: The invention relates to a method of separating components of a fluid mixture comprising the steps of providing a fluid, providing a sorbent structure (120), sorbing a first component of the fluid, desorbing the first component, and electrokinetically biasing the first component in a direction other than the vector of the fluid mixture.

Abstract: The invention provides a non-cyclic, meso-frequency traveling wave electro-kinetic system capable of use in purification/separation and/or refrigeration/heat pump processes. In particular, the invention provides an adsorption system that can be used for fine or bulk chemical separations of liquid and gaseous materials. Similarly, the adsorption system can be readily adapted to function as a refrigeration/heat pump unit for use in heating and cooling systems. This reusable adsorption system provides high efficiency purification and/or cooling/heating with low energy demands and no moving parts. The invention can function in parallel or in series with other similar such adsorption units (though it can also operate as a single unit).
