Optical analysis of various reflectors applied in solar beam down tower

The concept of the reflective solar tower is based on the reflection of the solar radiations from heliostats toward reflective mirror at the top of the tower and then redirected the radiation to one of its foci on the ground. This new arrangement would allow setup the energy collection at the ground...
