Yes, someone invented a miniature tumble dryer, with dimensions of only 20x8x5 inches and a weight of 2 lbs. I suppose this could useful if you’re in an incredibly small apartment, or dry most of your laundry outside. But other then that, it’s kinda silly. I wonder how long it would take to do a load of laundry…probably too long. If you’re interested, it’s available now for $149.
