  • Publication number: 20120216863
    Abstract: Solar energy concentrator architectures employ an array of electro-optical liquid prism modules to deflect sunlight onto PV cells. Without any mechanical moving parts, the dynamic liquid prism allows the concentrator to adaptively track the daily changes of the sun's orbit. The liquid prism modules may be arranged, for example, into a sheet-shaped beam steering array; a condenser device such as a Fresnel lens is then used to focus the light deflected by the modules onto one or more PV cells—preferably CPVs. Another possible concentrator architecture requires arranging a plurality of liquid prism modules into a semi-spherical pattern, such that light impinging on the modules is directed onto one or more PV cells or CPVs.

  • Patent number: 8076820
    Abstract: An electro-osmotic pump includes a pump chamber having a wall fabricated of an electric double layer material, the surface area of the electric double layer material being high relative to the volume of the chamber. An electric potential applied across the material causes a fluid in the chamber to be transported through the wall. A nastic actuator includes the electro-osmotic pump and an actuator chamber, having a variable volume, coupled to the pump chamber. A superabsorbent polymer is disposed in the pump and actuator chambers, such that transport of the fluid into the pump chamber results in absorption of the fluid by the superabsorbent polymer, causing the actuator chamber to increase in volume. When the electric potential is applied across the superabsorbent polymer, the superabsorbent polymer expands, further causing the actuator chamber to increase in volume.

  • Patent number: 7443062
    Abstract: A heat pipe is partially-filled with a liquid, such as water, and is used to transfer heat from a rotating element, such as a rotor, via phase change and internal recycle of the liquid. Several heat pipes may be disposed radially around the rotating axis of the rotating element. The heat pipes may have a curved inner surface with a curvature not corresponding to the central axis of the heat pipe and positioned opposite the rotating axis so to experience greater centrifugal forces, to advance formation of a liquid film to improve heat transfer. For a rotor, the heat pipes, though individually placed as revolving heat pipes, in total exhibit behavior that approximates the favorable heat-transfer behavior of a single larger rotating heat pipe, but with heat-transfer surface area dispersed throughout the rotor, and without compromising structural integrity of the rotor shaft.
