This is NOT a GearCrave April Fool’s joke…it’s a concept design entry in the Greener Gadgets Competition ‘08. Sevin Coskun’s combination washing machine and toilet is built to save water by routing the wash water into the toilet tank. Instead of flushing plain water, you use the washing machine’s runoff to wash away your runoff. A brilliant concept with only one major design flaw–there’s nothing to stop your Superman underwear from falling right into the toilet if you forget to close the lid. That aside, we think this is pretty ingenious. [Core77]
