<p><P>PROBLEM TO BE SOLVED: To solve the problem that almost all conventional seawater desalination apparatuses require huge equipment such as an osmotic membrane and a pressurization system and vast electric power consumption and consequently economic burden and environmental load are large. <P>SOLUTION: This seawater desalination apparatus is simple and utilizes infinitely pouring solar light and heat. Thus the apparatus is primitive but is economical because of very small electric power consumption and is good for the natural environment. Further fresh water can be obtained for a long period of time and in addition salt can also be refined as a by-product. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
