Drop a bowling-ball size gizmo into your clothes hamper or laundry basket. First it burrows through the laundry, steaming everything to loosen soil, then it electrostatically sucks the dirt right out of the fabric before blowing hot air through the pile to dry. This futuristic concept from the Electrolux Design Challenge might make the washing machine obsolete. You’ll still have to fold, press and hang your clean clothes. Some things will never change.
