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.
Look at washing machine models and their capacities. Select the one that suits your needs. A compact washer can hold 8 to 12 pounds of laundry, a top-loading washer can hold 12 to 16 pounds, a front-loading washer can hold 12 to 20 pounds, and some super-capacity machines can hold even more. Scale.
