coondoggie writes: With barely enough space to um, sit, and with high capacity usage, the commercial airline toilet perhaps is an engineering marvel but little else. Boeing however is looking to that notion with a self-cleaning aircraft bathroom -- known as the Fresh Lavatory -- that the company says uses ultraviolet (UV) light to kill 99.99% of germs in the loo -- and even puts down the toilet seat lid. "We're trying to alleviate the anxiety we all face when using a restroom that gets a workout during a flight," said Jeanne Yu, Boeing Commercial Airplanes Director of Environmental Performance in a statement. "In the prototype, we position the lights throughout the lavatory so that it floods the touch surfaces like the toilet seat, sink and countertops with the UV light once a person exits the lavatory. This sanitizing even helps eliminate odors."
