Sunlight can desalinate seawater up to 25% more efficiently

Russian scientists in collaboration with international scientists have developed a new, more efficient algorithm for desalination of seawater.

At the moment, the most common generator of green energy is combined devices, in which solar seawater desalination plants are combined with mini-turbines. With their new method, scientists will increase their efficiency by 15% -25%.

The amount of steam that is produced in solar steam generation devices can be increased by adding nanoparticles with light-absorbing properties to the water. For example – nanoparticles of iron oxide and graphite.

The great advantage of the system is that there are no particles of gold and silver in it. Such processing would be very expensive. So the new method can desalinate and disinfect seawater only with the help of sunlight.

This is an effect that was discovered back in the early 2000s, but its authors, scientists from Australia and the United States, for some reason did not go beyond laboratory experiments.

The generator prototype developed for the application of the new technology, according to the creators, under ideal conditions will provide power up to 5 kW from an evaporation area of ​​200 cm2, and about half that given weather conditions.

The fluids are not nanotoxic. This means that after certain biophysical tests, such water can most likely be used on the farm without additional purification.
