"Sun in a box" would store renewable energy for the grid

Concentrated solar plants store solar heat in large tanks filled with molten salt, which is heated to high temperatures of about 1,000 degrees Fahrenheit. When electricity is needed, the hot salt is pumped through a heat exchanger, which transfers the salt''s heat into steam. A turbine then turns that steam into electricity.
