1 Solar Ponds Maya Braun (Israel) Adam Lipecz (Hungary) Samuel Nel·lo Deakin (Spain) Featuring: The Zebra Layer

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 fluid inside the pipes turns into steam The steam moves the turbine The turbine produces electricity The water in the lowest layer heats up to ≈90°C

4 Essential requirements for a solar pond Space Water Sun Salt

5 Energy Comparison Energy SourceGenerating Cost (Euro per kWh) Range of Power Oil0.251kW-10MW Coal0.031MW-1GW Gas0.031MW-1GW Solar PV0.8010W-10MW Wind W-100MW Biomass0.041kW-150MW Solar Pond0.1331kW-5MW (unlimited)

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 Low efficiency due to: o Heat losses o Bottom losses o Top losses o Radiation losses Efficiency

9 Our Solution Is…

10

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

12

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

14

15 Conclusions 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. Reasons of solar ponds failure Our “zebra layer” solar pond Complicated installationEasy to build Not efficient enough (only 17%) MORE EFFICIENT!!!
