Each drop is pure with Solar water Purifier

The solar water purifier collects heat from sunlight and uses it to evaporate unpurified water running through the panel. The vapour collects inside the glass forming the panel’s surface and is collected - leaving behind most impurities. Margaret Folkard and John Ward’s inspiration behind inventing the Solar Water Purifier has been effect of polluted water and water-borne diseases on the health and life expectancy of the population, young people in particular.
Let’s begin with a description of the appearance of the product. The Solar Water Purifier is a rectangular shaped unit that contains an array of 32 shallow, square trays interconnected by a series of weaves. The trays are made from a black plastic sheet that is vacuum formed onto an aluminium pattern to reach the desired cell shapes. The panel of cells is covered by a sheet of white-glass and sealed using the surface tensions of water vapour produced in the unit. The undersides of the black plastic trays have been thermally insulated to maximise heat absorption. The unit is framed by an aluminium mount for strength and to keep shadowing to a minimum. It is also fitted with folding legs, so that the entire system is inclined at 12.5º to the horizontal.
