Due to its energy consumption, desalinating sea water is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide. Currently, approximately 1% of the world's population is dependent on desalinated water to meet daily needs, but the UN expects that 14% of the world's population will encounter water scarcity by 2025.
We propose a novel and advanced desalination system that works autonomously using sustainable resources of solar energy and seawater. Normally, the temperature range of the solar thermal heat is around 80 °C which is not high enough to harvest fresh water and salt from fully evaporated seawater. Therefore the conventional solar desalination method is slow and generates brine back to nature that causes ecological problem. Mean while CTEE's Thermal Energy Conversion Technology allows to get an upgraded heat out from low-grade heat source for example 80 °C solar thermal input to 150 °C output heat which makes fast and complete seawater desalination process without producing brine waste.
