In this form, the Operating Tank has an open bottom, and is partly submerged in the ocean. The action of these waves then pulls water from the ocean upward into a closed tank through a tube with a check valve. This water is then pushed out of the tank and into a storage container on dry land where the salt-water can be used for a variety of applications.
Solar-Gradient Ponds –
The Hydrautomat can be used to supply salt-water for use in solar gradient ponds, which can be used to produce electricity, salt, and even distilled water.
- What is a Solar-Gradient Pond? – A solar gradient pond is an artificial pond that is filled with brine and water. The top layer of the pond consists of water, while the bottom layer consists of brine (a denser form of salt-water). The water on the top allows light from the Sun to pass through and heat the brine below the water. The heavier salt content in the brine absorbs heat from the sun and prevents the brine from losing heat via convection, which would normally happen with freshwater or seawater. The brine in this pond can get as hot as 194 degrees Fahrenheit.
- Power Generation from Gradient Ponds – The heat from a solar gradient pond can be used to heat a refrigerant which would then be sent to a turbine for generating electrical power. Waste heat could be sent through a heat exchanger to preheat the incoming refrigerant for even more power.
- Solar-Desalination – The Hydrautomat can be used to pump water for Solar-desalinations systems, both supplying seawater for evaporation, and water for use as coolant in a condensing coil.
- Salt Generation - The solar desalination process leaves salt behind after water is evaporated off. This salt can be then sold for a wide variety of purposes, such as rock salt for roads, salt tablets for water softeners, salt as a dietary supplement, uses in various industrial and chemical processes, and many other uses.
