Abstract: A solar distillation device and method of constructing same are disclosed. The device employs a fluid flow surface for controlling the thickness of a flowing, laminar fluid (i.e., seawater in preferred embodiments) film. The fluid is deposited on an upper end of the flow surface where a relatively thick layer forms. The fluid flows over a fluid dispersal region and then over an active region where the surface area is designed to control the fluid film thickness for maximum evaporation. An outer domed surface surrounds the fluid flow surface and may enhance the heating effect from the sun.

Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing algae film. The algae film flow may be gravity-induced or the result of an alternative force. The algae is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The algae film flows over a fluid dispersal region where the surface area is expanding, which results in thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. While in the active region, the algae film may absorb carbon dioxide, while releasing water vapor. Hydrogen gas may be captured from the process, as well.

The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.
