Abstract: A system for cooling the temperature of a body of water having a top surface exposed to sunlight comprises hydrophilic balls distributed on, and in direct contact with, at least part of the top surface characterized prior to the distribution by a pre-distribution surface area. The balls have diameters within a range of 100 microns to 3 mm, and albedos within a range of 0.15-1.0. The balls comprise recycled glass and air-entrapping pores. The hydrophilic surfaces of the balls provide a total wetted surface area after the distribution greater than the pre-distribution surface area of the water, facilitating the cooling.

Abstract: Embodiments generally relate to methods and apparatuses for generating ice. In one embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the formed ice having a higher albedo than it would have had if the step of lowering the temperature had been carried out on the water without first carrying out the step of introducing the material. In one embodiment, the material is selected such that an aqueous solution of the material is alkaline. In another embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the ice forming at a faster rate than the rate at which it would have formed if the material had not been introduced to the water.

Abstract: A polymeric switch in which a switching channel is formed in a polymer layer. The channel is formed by a micro-machining technique such as laser ablation or photo-imaging. A liquid metal switch is contained within the switching channel. The liquid metal switch operates by making or breaking an electrical circuit using a volume of liquid metal. Electrical contact pads within the switching channel are wettable by the liquid metal and provide a latching mechanism for the switch. The polymer layer may be located between two switch substrates. Solder rings are attached to the perimeters of the switch substrates. The solder rings are wettable by solder and facilitate the creation of a hermetic seal between the substrates.
