Abstract:
A buoyant water heating device that may be used in a natural setting, such as a pond or lake, or in a man-made water-containing apparatus, such as a pool or water-treatment lagoon. The device comprises a water-filled, generally cylindrical anchor member coupled to a hollow, generally annular base member, and may he used alone or in combination with multiple other devices to create a free-floating blanket on the surface of the water. The device absorbs solar energy to heat water external to the device, and also provides a layer of thermal insulation between the water and the air above the device.
