World Sensation in Seawater Desalination –
Eric Hoyer, August 28, 2025
Water scarcity is one of the greatest global challenges of our time. Millions of people around the world lack access to clean drinking water.
Eric Hoyer has now developed a process that can fundamentally change this situation.
The Invention
-
More than 1,000 liters of drinking water per night – from just one square meter of evaporator surface
-
Operation without chemicals, without high pressure, without complicated technology
-
Energy source: sunlight and natural heat storage (e.g., steatite heated up to 500 °C)
-
Design: multiple vaults or caverns working alternately – evaporation and condensation occur gently, evenly, and in a natural cycle.
How It Works
-
During the day parabolic mirrors and solar energy charge the solid heat storage (steatite).
-
At night seawater evaporates inside the vaults. The water is evenly distributed in thin films (“shot application”).
-
The vapor condenses in cooler sections and delivers pure drinking water.
-
The remaining brine is collected, can be concentrated, and even used for salt recovery.
Advantages
-
✅ Natural – no chemicals, no membranes, no high pressure
-
✅ Sustainable – powered purely by solar heat and solid storage materials
-
✅ Decentralized – suitable for villages, cities, and coastal regions without large infrastructure
-
✅ Efficient – more than 1,000 liters of clean water per night on minimal space
Significance
This process is not just a technical innovation, but a revolution in water supply.
For regions suffering from water scarcity, it opens up a new future: clean water, independent of fossil energy or mega-infrastructure.
Eric Hoyer has taken on the challenge – and delivers a world sensation that can set the new global standard.
