Innovation discovered by scientists could once and for all end the world's thirst with the use of solar energy. Find out how it works!
An innovation promises to change the reality of millions of people around the world: a desalination system solar powered capable of transforming salt water in drinking. Developed by scientists at King's College London in collaboration with MIT and the Helmhotz Institute, this technology holds incredible potential for revolutionize access to clean water, especially in developing countries, according to the Olhar Digital website.
The system uses specialized membranes to separate salt ions from water by adjusting voltage and water flow based on the availability of sunlight. In tests in India and the USA, the solar energy system was shown to produce a significant amount of fresh water daily, offering an economic and sustainable solution for communities affected by water scarcity.
Applications beyond desalination
In addition to transforming salty water into drinkable water using solar energy, this technology has the potential to:
- The price of energy in Germany has soared to R$5.864/MWh due to the dunkelflaute, the terror of renewables, while the average cost in Brazil is around R$600/MWh
- PUC-Rio at the forefront of innovation! New revolutionary method for green hydrogen, with unprecedented materials, promises clean, safe and ecological energy, leading the race for global sustainability!
- Offshore electricity: Project with incentive for COAL in Brazil could cost R$595 billion and increase electricity bills by 11%
- Surprising breakthrough in solar energy! New molecule stores energy for months, creating a revolutionary solution that enables energy use at night and during winter
- Be used in irrigation and wastewater treatment;
- Reduce costs and carbon emissions in the agricultural sector;
- Provide a sustainable solution to global water and climate problems;
- Mitigate the effects of climate change, especially in agriculture;
Furthermore, by providing fresh water to irrigation at a price reduced, without compromising volume, it can help farmers face challenges such as drought and high water costs.

Next steps and future impact
Researchers are planning to apply this technology that uses solar energy to other sectors, such as wastewater treatment and alkaline production to help the ocean absorb more CO2 from the atmosphere. This would not only decarbonise agriculture, but also bring wider environmental and climate benefits.
In a world where around 40% of the population faces water scarcity, this innovation promises to be a game-changer, offering reliable access to safe drinking water, emissions-free on site and at a discount of approximately 22% compared to traditional methods.
This even more improved technology has already been patented in Brazil via INPI and is being applied in the treatment of water produced from oil with secondary generation of reuse water and green hydrogen, being the only technology in the world that uses liquid waste as a primary source for H2V production. and zero carbon emissions.
May God bless this initiative. And don't just talk about it. Or wanting to take advantage, instead of thinking about the population that suffers so much due to the lack of such a precious commodity, which is water
I understand that, in the process, the extraction of salt occurs, which will need to have some destination, so as not to promote an imbalance in the salinization of seawater; which could have devastating effects on the marine biome. Am I right?
That's what I was thinking. What are they going to do with the salt waste? Will our oceans become a Dead Sea? What will the Red Sea and the Persian Golgo be like?
Will the Pacific Ocean become rebellious?
The Atlantic Ocean was once known as Dark! What about the warming of ocean waters, such as the Pacific, which already causes El Niño? How is the situation?
As the process is done over sea, it is less complicated
What a wonderful discovery. This is good for humanity. If the rulers do not extort this good, it will be a joy for humanity.👏👏👏👏👏👏
New system that transforms salt water into drinkable water:
Regarding this system, which I consider to be impactful due to the benefits it could produce, especially in regions that are so lacking in drinking water. However, my question as a layman on the subject that I cannot stop talking about is the following: It is true that every process involving change in relation to the environment generates positive and negative externalities. Regarding the negative ones, which I think are one, I would like to know what happens to the amount of salt that is separated from the salt water.
