Cellular Element
Summary: The present invention provides a scalable means for the purification,
including desalination, of water by use of multiple layers of thin plastic. These layers would be convoluted into bubbles and manifolds forming
channels, thermal transfer interfaces and containment, as well as thermal isolation in contained gas volumes.
Layer Definitions
1) Layer above ‘2’ forms the outer dome. Provides thermal isolation.2)This Layer, above ‘3’ forms the inner dome and evaporative containment vessel. Is
thermally isolated from airflow above the system by external dome above it.3) Not a complete layer:, but above 4, constitutes the evaporative structure. Should be
porous water insoluble being of food-grade materials and capable of sustained temperatures approaching 100 degrees centigrade.
4) Layer above ‘5’ forms an elevated cup whose interior bottom is formed by the sheet two layers below and is additionally accessed by the end point of the spiral one layer below. The layer is otherwise in contact and seals with the layer below it. It should be non-porous, water insoluble and be of food-grade materials on its upper-surface and capable of sustained temperatures above 100 degrees centigrade.
5) Layer above ‘6’ is composed of a spiral channel of the same curvature as that below. Its spiral is principally contained by the spiral below except at its endpoints on the output end that terminate outside the thermal containment bubble created by layer below, and of the end closest to the center of the cell that terminates opening onto the bottom of the central cup.
6) Layer above ‘7’ forms the incoming channel by means of a spiral conduit where the layer is otherwise in contact with the layer above it forming seals around the perimeter of the spiral channel and in a central depression forming the floor of the cup two layers up. Feeds perforation with effluent process water slightly enriched in saline concentration.
7) Layer above ‘8’ forms the upper boundary of the tube described above. Should be sealed along the sides of the tube of Layer ‘6’. Forms sealed regions around the features on the next layer up to provide thermal isolation of those features. Is perforated into flat tube below. Lower surface is of food-grade materials.
8) Layer constitutes upper boundary of a wide but shallow tube and contains water flowing downhill on a slight grade to provide suction and seawater or process water to be purified for slightly saline enriched water to mix. The water should be at the lowest ambient temperature easily available.
9) Bottom layer constitutes Collection Channel for freshwater effluent to be routed for collection.

Outgoing Water Flow Spiral
Incoming Water Flow Spiral
Details of Spiral Incoming and Outgoing ChannelsDepicted above are the nested spiral layers forming the mechanism for the water’s thermal-transfer counter
current gradient flow. Water enters the outer loop of the upper spiral through a hole in the layer above it. The water then flows around the incoming spiral loops to enter the inner cup. The water level rises to cover the exit
channel’s opening. Warmed water of slightly increased salinity flows around the outgoing spiral loops, exchanging heat as the water moves in opposite directions, incoming water warming, outgoing water cooling,
until it changes course and exits the area under the upper domes, ending its thermal exchange cycle. The increased-salinity water then drains from the system.

Relief KitThis opportunity focuses on development of personal or small village adaptation of the PCDA for impoverished people where humanitarian activities exist in relief-packaged bundles. The adapted version of the PCDA would be portable by small truck (potentially could include a smaller backpack-portable personal configuration) allowing its use in remote areas. Since the PCDA has no moving parts and requires no other energy aside from sunlight, its use by people without facilities or technical training is feasible. The PCDA may be readily integrated as a component of relief packages currently in humanitarian distribution.
