Cover for pond used to collect solar radiation
First Claim
1. A cover for withstanding stormy weather and increasing solar heating of a body of water in a reservoir having a bottom and a side edge extending upwardly from and surrounding the bottom, the cover comprising:
- a) a sheet disposed over the body of water, the sheet being more transparent to visible radiation from the sun than to infrared radiation;
b) means for anchoring the sheet in a substantially horizontal plane down around its periphery to the side edge of the reservoir to prevent wind from lifting the sheet from the reservoir;
c) means forming a retaining wall extending above and around the periphery of the sheet;
d) means for covering the top of the sheet with a layer of water and holding the water on the sheet at a level substantially the same as the top of the retaining wall; and
e) means for drawing water from the top of the sheet.

Abstract
A cover for withstanding stormy weather and increasing solar heating of a body of water is disposed over the surface of the water. The cover is more transparent to visible radiation from the sun than to infrared radiation, and is anchored and sealed around its periphery over the surface of the body of water. Means are provided for reducing the pressure between the bottom of the cover and the top of the water to subatmospheric, and for flooding the top surface of the cover with a layer of water, and draining the layer of water from the top of the cover.
