Solar-Water - Fresh Water Generation Solar Technology

SHARE

The first hydro-infrastructure project to be completely carbon neutral designed to produce and make available a massive ongoing amount of pure, clean water for municipal, industrial, farming and biotech consumption.

hydrologic cycle
Desalination facilities based on technology that mirrors the natural hydrological cycle process: evaporation, condensation and precipitation, with only the sun as the energy source.The technology involves a dome – a hydrological sphere – constructed from glass and steel into which sea water flows. The energy generated to super heat the continuous inflow of water and to create a constant water cycle within the dome – the equivalent of up to 20,000 suns – produced by focusing concentrating solar radiation, from a large number of parabolic mirrors (heliostats) surrounding the domes, onto the glass and super conductive steel frame structure. Through this process, the sea water evaporates, condenses and is precipitated as fresh water. The brine gathers at the bottom of the dome’s basin, is extracted and sold commercially.THE PROCESS

Seawater Intake
In a Solar WaterTM installation, freshwater will be generated from the evaporation of a constant inflow of seawater fed into a large scale geodesic dome steel and glass structure (in various diameters from 20m to 120m).
Solar Power heats the Dome
The water is then heated using energy produced by solar radiation enhanced by the use of solar energy mirrors (heliostats) reflecting sunlight continuously onto the dome throughout the day.
Seawater is Superheated
The radiative flux is focused and super-conducted down to the lower dome to boil the seawater creating a cauldron effect.
Condensed & Precipitated
The resulting fresh water can then be used for irrigation, industrial or general household purposes, and can undergo secondary treatment as necessary for drinking water.
The Four Subsystems
The Solar WaterTMDesalination Plant comprises 4 subsystems:
  • Intake subsystem
  • Freshwater production subsystem
  • Freshwater supply subsystem
  • Salt/Brine removal subsystem.
Volume of Fresh Water
The output of fresh water from the Solar WaterTM domes will provide many thousands of cubic metres of fresh water per day.

There are many variables involved – size of the dome, geography, latitude, availability of continuous sunlight, the number of heliostats and ambient operating conditions. The exact costings and volumes will be determined on a case by case basis, with the dome size being important.

Salt by-product
90% of desalination plants dispose of brine through ocean discharge causing horrific damage to marine ecosystems.

The Solar WaterTM process will not discharge brine into the sea. The salt is sold as a commercial by-product, for industrial use – lithium batteries, grit for roads, fertiliser or detergents.

While 70% of the planet is covered in water, there are increasing water shortages as demand is outstripping the supply of fresh water. Only 3% of the world’s water is fresh water.

Climate change is affecting traditional supplies, even while rapid population growth and industrial development are increasing demand. It is estimated that global demand for fresh water will exceed supply by 40% in 2030, due to a combination of climate change, human action and population growth.

Over one billion people lack access to water and almost a further 3 billion find it scarce for at least one month of the year, thousands are dying every day. Many of the world’s largest cities are in a situation of water stress, some critically so. It is a growing problem. In the poorer areas of the globe, children are literally dying due to lack of access to clean water.

Expanding populations, human activity and their impact on nature are having an increasingly negative impact on the availability of water, especially where water is most needed. It is becoming clearer that more and more regions of the world are facing serious water problems.

In the future, we will also start to see national and transboundary conflicts over freshwater supplies, armed conflict over water shortages and irreversible damage to marine life. There is a real and substantiated water crisis that is getting progressively worse.

TRADITIONAL METHODS ARE NOT WORKING
Change is needed. Current desalination methods are environmentally unsustainable and expensive.
  • 18,500 desalination plants in the world.
  • Highly reliant on burning fossil fuels to extract water.
  • Poisoning our oceans – 90% dump brine into the sea.
