| 20090173678 | Vertical evaporation technologies - This invention captures the salt from salt water in an easily transportable form. Most desalinators of the past were enclosed to capture the water vapour that escaped for the production of salt free water. They are enclosed which subtracted some of the suns energy. This invention has no enclosures. This invention can divide water into smaller units. This invention evaporates the water before it falls off the evaporating surface, thus having less water on the evaporating surface which makes evaporation easier. The surface tension of water is reduced by the small amounts of water on the evaporation cloths and with the use of water loving evaporation cloths. When water is dropped on cotton it wicks away and tries to equally distributes the water over its entire length and width. An equitable distribution of water to evaporation cloths is achieved by this invention. An ability to distribute water at various rates to an evaporation cloth in order to deal with the different evaporation rates of day or night or sunshine or cloud. | 07-09-2009 |
