<p>A method and a system of solar heating 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 (10, 11) is a sealed bag with its wall (12) comprising a thin translucent film of plastic, which encases a translucent liquid (13) and a translucent gas (14), so that each coverite presses against 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 water (15), and reduces heat absorbing evaporation of the water (15) to the air (17), and thermally insulates the water from the air. The liquid (13) and the gas (14) may conveniently be water and air respectively and the plastic may suitably be a polyolefine such as polyethylene.</p> |
