A method and apparatus for storing, transporting, and releasing high
grade, thermodynamically useful energy for a wide variety of uses. Solar
energy is collected and reflected onto a heat storage container using a
three-mirror reflecting system. This invention involves a method of
heating the heat storage container using a primary, secondary, and
tertiary system, which has a core that is partially comprised of an
aluminum alloy and a metallic shell with a higher melting point than the
aluminum alloy contained within. Once heated, the storage containers can
then be transported to different storage areas in order to heat secondary
storage containers or can be used in processes such as cooking, powering
heat engines, water heating, absorption refrigeration, or drying garbage,
waste, or biomass.
