Abstract
A solar still system including a storage tank, a piping network, a vessel, and a basin having an open top and at least five fins extending vertically from a bottom surface of the basin is described. The basin is disposed in an insulated enclosure with a fiber insulator filling a space between the basin and the insulated enclosure. The insulated enclosure has a top surface with a transparent cover. A collection tray is attached to an inner face of a first side of the insulated enclosure under the transparent cover, a glass stopper is attached to the transparent cover over the collection tray. The vessel has an open top including a lower convective zone, a non-convective zone, and an upper convective zone and includes at least four fins. A method of desalination using the solar still system is also described.

A solar still system, comprising:
- a storage tank;
- a piping network;
- a basin,
- wherein the basin has an open top,
- wherein the basin has at least five fins extending vertically from a bottom surface of the basin,
- wherein the at least five fins are rectangular positioned parallel to one another and are 800 to 1000 mm in length, 30 to 40 mm in breadth, and 0.1 to 5 mm in thickness,
- wherein the basin is disposed in an insulated enclosure,
- wherein a fiber insulator fills a space between the basin and the insulated enclosure,
- wherein the insulated enclosure is a square with a first side having a first height and a second side having a second height,
- wherein the first height is shorter compared to the second height,
- wherein the insulated enclosure has a top surface with a transparent cover,
- wherein the transparent cover is attached to a top of the first side and a top of the second side,
- wherein the transparent cover is at an angle of 5 to 20°,
- wherein a collection tray is attached to an inner face of the first side under the transparent cover,
- wherein a glass stopper is attached to the transparent cover over the collection tray,
- wherein the insulated enclosure is covered in one or more metal sheets,
- a vessel having an open top,
- wherein the vessel having an open top has a lower convective zone, a non-convective zone, and an upper convective zone,
- wherein the vessel having an open top has a conical shape with a top surface and a bottom surface,
- wherein the vessel having an open top has at least four fins extending vertically from the bottom surface of the vessel having an open top,
- wherein the at least four fins are rectangular and are positioned parallel to one another and are 100 to 300 mm in length, 30 to 70 mm in breadth, and 0.1 to 5 mm in thickness,
- wherein a surface area of the top surface of the vessel having an open top is greater than a surface area of the bottom surface of the vessel having an open top,
- wherein the piping network fluidly connects, in the following order, the storage tank with the vessel having an open top and the vessel having an open top with the basin.
