Lessons Learned

The receiver area is about 22 square meters, which receiving the sun rays. It consists of porous ceramic elements conducting a flow of air sucked in from outside. The heat storage system is filled with a packing of ceramic elements. These elements are heated by the hot air, and the heat is retrieved by reversing this process, therefore, the power generation can continue with clouds pass overhead.
