Molten salt can be employed as a thermal energy storage method to retain thermal energy collected by a solar tower or solar trough of a concentrated solar power plant, so that it can be used to generate electricity in bad weather or at night.
In addition to a washer's external dimensions, you will also want to think about size of the washing drum inside the unit. Excluding compact units, most of which have a drum somewhere in the 2-cubic-foot range, the majority of standard-size front- and top-load washer drums today range from roughly 4 to 5 cubic feet. That's a great range for a typical 8-pound load.
Compact front load washers range from 2.0 to 2.5 cubic feet, and most high efficiency washers range from 3.1 cu. ft. (IEC) up to 4.7 cu. ft. (IEC) â which represents a significant upgrade from conventional top load washers. As a rule of thumb, to accomodate a king-sized comforter, a washer capacity of 3.8 cu. ft. (IEC) or greater is required. For a queen-sized comforter, approximately 3.5 cu. ft. (IEC) or more is needed.
