My design for a Solar Powered Atmospheric Water Generator: This machine uses mostly scrap and recycled parts and components to cut costs. The left side of the unit is an old refrigerator, the copper coils are the only expense besides the electrical (solar panels). The center compartment of the unit is the condenser coil and the water collector pan below, which is attached to a small low voltage DC water pump/filtration system.
How it Works: Water is cooled in the refrigeration side and pumped out side the sealed unit to the condenser coils which is inside a box made of metal grating to allow outside air to flow through the unit and over the coils (a low voltage DC car radiator cooling fan could be placed inside the center compartment to help circulate the hot air from outside over the cooling coil). Water condenses on the copper coils and drips into the collector where a second pump picks it up and filters the water into a “potable water” holding tank in the third stage.
Cost: The whole system can be built for less than $500 in materials and run on one or two solar panels.
