  • Patent number: 11780745
    Abstract: A solar distillation system includes at least one solar panel configured to reflect sunlight, and a distillation tube adjacent the at least one solar panel that is to receive a liquid to be processed into fresh water. The liquid flows through the distillation tube and is heated by the reflected sunlight. At least one supplemental distillation unit is connected to the distillation tube and has at least one curved surface to receive the reflected sunlight. The least one supplemental distillation unit includes a plurality of sprayers configured to spray the liquid onto the at least one curved surface to be further processed into fresh water.
    Type: Grant

  • Patent number: 11325846
    Abstract: A solar distillation system includes at least one solar panel to reflect sunlight, and a distillation tube adjacent the at least one solar panel. The distillation tube is to receive brine to be processed into fresh water. The brine is to flow through the distillation tube and is heated by the reflected sunlight. A first supplemental distillation unit is connected to a first end of the distillation tube and has a curved surface perpendicular to the distillation tube to receive the reflected sunlight. A second supplemental distillation unit is connected to a second end of the distillation tube and has a curved surface perpendicular to the distillation tube to receive the reflected sunlight. The first and second supplemental distillation units each include sprayers to spray brine onto the respective curved surfaces to be further processed into fresh water.

  • Patent number: 8518202
    Abstract: The present invention provides a method and apparatae used to prepare a shaped and molded multilayered article formed from a heated thermoplastic sheet and a first plastic sheet that are driven into melt-bonding contact by a stream of gas. The method involves applying a stream of gas (450) against the first surface (417) of a first plastic sheet (411) so as to drive a second surface (420) of the first plastic sheet against and into contact with the first surface (432) of a heated thermoplastic sheet (423) as the heated thermoplastic sheet is formed (e.g., extends downstream from the sheet slot 426 of a sheet die 429). The second surface of the first plastic sheet is defined by a thermoplastic layer.
