Abstract
Means for substantially reducing evaporation and heat loss from an open liquid surface comprising a plurality of pentagonal dodecahedrons which substantially cover the surface of the liquid. The dodecahedrons may be hollow or solid but are preferably made of structural foam having a specific gravity which is approximately one-half the specific gravity of the liquid.
Claims20
In combination, a tank containing liquid and a plurality of dodecahedrons floating on the surface of said liquid and substantially covering same, each of said dodecahedrons including twelve identical pentagonal faces, some of the edges of said dodecahedrons making contact with adjacent edges of adjacent dodecahedrons, others of the edges of said dodecahedrons making contact with adjacent surface of adjacent dodecahedrons, and some of the surfaces of said dodecahedrons making contact with adjacent surfaces of adjacent dodecahedrons.
In a system for covering a body of liquid wherein a plurality of bodies are floated on the surface of the liquid to substantially cover same, the improvement wherein each of said bodies is a dodecahedron having twelve identical pentagonal faces.
A float for use in preventing contact between air and liquid comprising:
- a pentagonal dodecahedron, a plurality of said dodecahedrons being adapted to float on the surface of said liquid.
Means for preventing the evaporation of liquid from the surface thereof comprising:
- a plurality of pentagonal dodecahedrons floating on and substantially covering said surface of said liquid, different ones of the surfaces and edges of each of said dodecahedrons making edge-to-edge, edge-to-surface, or surface-to-surface contact with adjacent dodecahedrons.
