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.
There is no standard size for a bath sink. Some petite basins are just big enough for washing hands, while the largest sinks are big enough for washing hair or delicate clothing. Most round sinks are 16 to 20 inches in diameter, while most rectangular sinks are 19 to 24 inches wide and 16 to 23 inches front to back. Typical basin depth is 5 to 8 inches.
