So e.g., it is in every
salad sauce prepared with vinegar and common salt. The used white oil serves
also as a raw product in the cosmetics industry. Diagram 48 shows the function
of a latent heat storage system.

Diagram 49 shows an example
of the technical progress the solar energy technology has went through alone
in the three years from 1995 to 1997. In general, a trend can be noticed towards
always more compact installations. One goal of today's technical development
work is to produce long-term storage systems with a high energy storing capacity
as well as very effective layer storage systems for the immediate use of the
solar energy produced.
