Some solar power plants use mirrors to focus sunlight on a central collector. The energy from sunlight causes water in the
central collector to boil and produce steam. A generator uses
the kinetic energy of the steam to produce electrical energy.
How could a thermal battery help this type of power plant
generate electrical energy 24 hours per day?
