Title: Solar heating of water utilizing coverites

Patent ·
OSTI ID:6065142

A method and a system of solar heating a body of water, which has its surface exposed to air and radiation from the sun, by covering the surface of the body of water with a floating blanket consisting of thousands of coverites. Each coverite is a sealed bag with its wall comprising a thin flexible translucent film of plastic, which encases a translucent liquid and a translucent gas, so that each coverite compresses its neighboring coverites, whereby its thin flexible wall conforms to the shape of the contacting part of the neighboring coverites' thin flexible walls, whereby the resulting blanket of coverites admits the solar radiation to reach the body of water, and reduces heat absorbing evaporation of the body of water to the air, and thermally insulates the body of water from the air. The liquid and the gas may conveniently be water and air respectively and the plastic may suitably be a polyolefin such as polyethylene.
