You would have heard about solar panels making electricity but now Swiss innovators have introduced a sort of “Solar Dish” which is a source of heat and fresh water too.
Who is Producing It?
The intellects of Swiss companies and universities are working upon this idea of producing a solar dish with dual advantages. It will have not only power but also water for the benefit of humanity, and it will use its heat to turn salt water into a drinkable one.
The Swiss government has called it a High Concentration PhotoVoltaic Thermal system. the team working on it is given $ 2.4 million to develop and test it.
How it Works?
Michel says, “sun is the most abundant energy that we have.” We can use it for different purposes as it is the best thing that God has given us. Now, Sun will help in extracting pure water with electric power.
There are millions of tiny mirrors attached to it. These mirrors draw sunlight to a common point and then reflect it to the receivers. Receivers are already made up of millions of energy-converting chips. So they transform this light into electricity.
The material required for it is elementary, and it has replaced expensive steel or glass with simple concrete foils of metal.
“Anti-heating (overheating) coolant system”
It also has a heat-absorber (in-built coolant system), which prevents it from overheating or melting when over-heating. And instead of wasting this extra heat, it uses it to purify salt water. This excessive amount of heat changes the salt water in the desalination chamber into a potable one by evaporation.
The estimate about making freshwater is also satisfactory. IBM reports claim that within 8 hours, the system can produce 30-40 liters of potable water with the help of one square meter of receivers.
Comparison with Solar Panel
- Its shape, work and cost differ from that of a solar panel.
- It has a dish-like shape instead of a flat solar panel.
The Swiss researchers claim that this latest improved technology will cost less than panels and could be affordable to many. The material needed for it is not expensive at all.
Compared to solar panels, it will be more helpful, beneficial, and cheaper. Solar panels can only produce electricity; it will also prepare fresh water for drink and use.

Critics are hopeful that if this formula succeeds than this technology would surely replace coal power technology as it is simpler plus handy.
Researcher Andrea Pedretti told, “The design of the system is elegantly simple.”
