One of my favorite appliances is the washing machine and dryer. It didn't use to be, in fact washing machines used to be downright boring. But have you seen the new Samsung and LG washing machines? They are works of art with tons of gadgetry and LCD screens, etc,
With that said, most conventional washing machines are quite wasteful. After cleaning your clothes the water is dumped down the drain. And as much as I don't like the wastefulness, I am not sure I want to recycle dirty underwear water. The Mr. Klein concept washer reuses the water and filters it before the next wash cycle. Still just a concept, will let you know if it makes it to prime-time.
