2. What is a solar pond?
A pool of saltwater which acts as a large-scale solar thermal energy collector
It includes an integral heat storage for supplying thermal energy

3. How do solar ponds produce electricity
The water in the lowest layer heats up to ≈90°C
The fluid inside the pipes turns into steam
The steam moves the turbine
The turbine produces electricity

4. Essential requirements for a solar pond
Space
Water
Salt
Sun

6. Advantages Environment friendly energy – no pollution!
Reliable energy source
Stores heat, so it can be used 24/7/365
Can be constructed according to requirements
Low maintenance costs

7. Disadvantages Localized Low efficiency Space availability
Salt and water supply

8. MAIN PROBLEM! Efficiency Low efficiency due to: Heat losses
Bottom losses
Top losses
Radiation losses
MAIN PROBLEM!

9. Our Solution Is…

10. THE ZEBRA LAYER!

11. Improving the efficiency! Decreasing the heat losses (bottom & sides)

13. The Zebra Layer® All In One solution
Insulation + heat exchanging pipes
People can easily and fast build new Solar ponds
Just lay down the foil
Create the salinity gradient
Your Solar pond is ready to use!
Really cheap

15. Conclusions Reasons of solar ponds failure
Our “zebra layer” solar pond
Complicated installation
Easy to build
Not efficient enough (only 17%)
MORE EFFICIENT!!!
We hope and believe that solar ponds have the potential to become an important source of energy in certain areas, and that the zebra layer will improve their functioning.
