Wearable Japenese Space Toilet

"Japan Aerospace Exploration Agency (JAXA) is designing a toilet, expected to be ready in 5 years, that is worn around the astronaut’s waist at all times. When the astronaut has to go, sensors automatically turn on a rear-mounted suction hose to remove the waste. Then an automatic washer and dryer cleans you up."  Makes going to space sound a lot less fun.
