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.
Measure the total space that the appliance will occupy next to the clothes dryer. Write down the width and depth measurements. Washers generally range in size from 25 to 27 inches wide and 25 to 34 inches in depth. Purchase a clothes washer that will fit inside the measured space. As a rule of thumb, a clothes washer, as well as clothes dryers, need to be about 1 1/2 to 2 inches apart and the same distance from walls on either side.
