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.
Size things up. Capacities of front-loaders and high-efficiency (HE) top-loaders keep increasing, with some washers handling up to 28 pounds of laundry. While most washers are 27 inches wide, some with large or jumbo capacities add an extra two or three inches.
