    Molten salt is used with solar energy to create steam, which will eventually be used to power an electric turbine.  The focused reflection of the sun’s rays are used to heat molten salt, and once it is hot enough it is pumped through a steam generator.  The steam is then used to power an electric turbine overnight, and the cold molten salt is pumped back into the collection tower it was heated in.  Thus, while solar panels collect light energy during the day, they also reflect thermal energy which is stored for later use.
