The invention comprises a float evaporation reduction apparatus and method of use thereof. Individual floats self-right, self-unstack, and/or self-move through elements of the float design, such as a wind redirection element and/or a stability element. In one case, floats use top-side ridges to redirect wind forces to form, interconnect, and/or stabilize a self-assembled monolayer of floats. In another case, floats use side friction/interconnection forces to stabilize adjacent floats. In another case, one float and preferably a spatially distributed set of floats gather localized information as to the surrounding environment, and/or communicate data and/or information back to a controller.

Present invention relates to the field of a storage tank design and can be used in the construction of tanks for storing light ends and, preferably, for storing gasoline. The claimed tank for storing petroleum products consists of a body, a roof and a floating protective cover comprised of a plurality of floating elements in the form of solids of revolution having the same shape. In the tank, a portion of the floating elements of the protective cover is situated below the surface of the liquid, and a portion is situated in the gas space of the tank. The distinguishing feature of the proposed invention is the floating elements, which differ from one another in shape and size by not more than 5%. Furthermore, the floating elements that make up the floating protective cover have a centre of flotation that is offset from their geometric centre. All of the elements of the protective cover are made of non-sparking metal. The technical result of the invention is that of reducing the rate of evaporation of the liquid and the concentration of vapors, suppressing the process of combustion and preventing the possibility of electrostatic buildup and spark discharge between the floating elements.

A batten bar is configured to secure first and second adjacent flat panels to a structural framework. The batten bar includes first and second inside legs, first and second outside legs, and a plurality of apertures disposed along the length of the batten bar. The first and second inside legs define a central channel. The first outside leg and the first inside leg define a first seal recess configured to receive and retain a first seal. The second outside leg and the second inside leg define a second seal recess configured to receive and retain a second seal. In an installed configuration, the first inside leg and the first outside leg are configured to contact the first flat panel along a first common plane, and the second inside leg and second outside leg contact the second panel along a second common plane.

A reservoir shading structure made of multiple consumer beverage containers. The containers each have a bottle portion, and a top portion preferably with a collar. The top portion is removed, inverted, and replaced in the bottle portion to extend into the bottle portion. The top portion is hermetically sealed to the bottle portion and a cap is welded into the top portion to hermetically seal the consumer beverage container. The consumer beverage containers are UV resistant, made of NSF/ANSI Rule 61 compliant material, and may include carbon black in their construction. Multiple consumer beverage containers are placed in a uniform layer across the surface of the reservoir to form a shading structure that reduces evaporation and microbial growth.

In accordance with one implementation, a floating cover system includes a plurality of cover-tethering mounts mounted along the periphery of a holding tank. Each of the cover-tethering mounts includes a guide portion insertable through a cover-holding element that is attached along a periphery of a holding tank cover. When secured to the plurality of cover-tethering mounts, the holding tank cover can rise and fall within the holding tank responsive to volumetric changes in the liquid and/or gas contained in the holding tank.

A cover system for a storage pond formed using a liner is disclosed. A cover flap, a liner flap and an anchor flap are preassembled either off-site at a factory or on-site. The anchor flap is disposed in an anchor trench and the anchor trench is backfilled. The liner is deployed and the perimeter is welded to the liner flap. The cover is deployed and the perimeter is welded to the cover flap. The above welding is preferably fusion welding and could take place in any order.
