“Water-efficient washing machines could be relics of the past should a new machine that uses plastic chips pan out. Friction and solvent are the main ingredients of getting clothes clean, and the Xeros may be the most efficient machine to utilize these two elements and minimize the role of water. The Xeros uses less than 2% of the water and energy of a conventional washing machine, using just one cup of water, a little detergent, and thousands of reusable plastic chips (as the “solid solvent”) to beat the clothes clean and absorb stains.”
