Abstract: Circulation systems for ponds, lakes, or other bodies of water. In one set of embodiments, water is drawn up from the depths of the body for exposure to the atmosphere and to generate an overall, high flow circulation pattern throughout the entire body. In other embodiments, the circulation in the body of water is primarily limited to an upper aerobic zone with only small and controlled volumes from a lower anaerobic zone being brought up. Each system preferably includes a flotation platform, dish, impeller, and draft tube with specific modifications to the various systems to adapt them for use in a variety of environments.

Abstract: Circulation systems for ponds, lakes, or other bodies of water using a flotation platform, dish, and impeller. One embodiment has a connecting arrangement between the drive motor and the impeller that permits the two to be easily and quickly coupled and uncoupled. The connecting arrangement also is designed to accommodate slight misalignments between the shafts. An arrangement to adjust and calibrate the depth of the inlet to the draft tube is disclosed. The system further includes solar panels that can be pivotally swung outwardly to open positions, angularly adjusted about a horizontal axis, and mounted to face toward the central axis of the flotation platform rather than away from it. Arrangements are further provided to monitor and control the components of the system including remotely from shore.

Abstract: A water-cooled distilling apparatus for purifying or distilling raw water. The apparatus includes a boiler, cooling tray assembly, and collection vessel. In use, raw water is initially poured into the boiler which has a self-regulating screen in it. As the water beings to boil, the screen rises to float above the raw water. The height of the screen above the water automatically adjusts proportionately to the rate of boil to proportionately expose more or less surface area of the screen. A water film forms on the exposed surface area of the screen and clean steam rises therefrom into the cooling tray assembly where it is deflected into a condensing area on each level of the assembly. In each condensing area, heat is transferred from the steam into coolant water in a reservoir, causing the coolant water to evaporate from the reservoir and the steam to condense on the bottom of the surface of the reservoir. Distillate formed by the condensing steam is then collected and transferred to a collection vessel.
